I been writing markdown files lately, and have been using the awesome table of content generator (github-markdown-toc) tool/script on a daily basis, but I'd like it to be regenerated automatically each time I press Ctrl+s, right before saving the md file in my sublime3 environment.
What I have done till now was to generate it from the shell manually, using:
gh-md-toc --insert my_file.md
So I wrote a simple plugin, but for some reason I can't see the result I wanted.
I see my print but the toc is not generated.
Does anybody has any suggestions? what's wrong?
import sublime, sublime_plugin
import subprocess
class AutoRunTOCOnSave(sublime_plugin.EventListener):
""" A class to listen for events triggered by ST. """
def on_post_save_async(self, view):
"""
This is called after a view has been saved. It runs in a separate thread
and does not block the application.
"""
file_path = view.file_name()
if not file_path:
return
NOT_FOUND = -1
pos_dot = file_path.rfind(".")
if pos_dot == NOT_FOUND:
return
file_extension = file_path[pos_dot:]
if file_extension.lower() == ".md": #
print("Markdown TOC was invoked: handling with *.md file")
subprocess.Popen(["gh-md-toc", "--insert ", file_path])
Here's a slightly modified version of your plugin:
import sublime
import sublime_plugin
import subprocess
class AutoRunTOCOnSaveListener(sublime_plugin.EventListener):
""" A class to listen for events triggered by ST. """
def on_post_save_async(self, view):
"""
This is called after a view has been saved. It runs in a separate thread
and does not block the application.
"""
file_path = view.file_name()
if not file_path:
return
if file_path.split(".")[-1].lower() == "md":
print("Markdown TOC was invoked: handling with *.md file")
subprocess.Popen(["/full/path/to/gh-md-toc", "--insert ", file_path])
I changed a couple things, along with the name of the class. First, I simplified your test for determining if the current file is a Markdown document (fewer operations means less room for error). Second, you should include the full path to the gh-md-toc command, as it's possible subprocess.Popen can't find it on the default path.
I figured out, since gh-md-toc is a bash script, I replaced the following line:
subprocess.Popen(["gh-md-toc", "--insert ", file_path])
with:
subprocess.check_call("gh-md-toc --insert %s" % file_path, shell=True)
So now it works well, on each save.
I have multiple functions stored in different files, Both file names and function names are stored in lists. Is there any option to call the required function without the conditional statements?
Example, file1 has functions function11 and function12,
def function11():
pass
def function12():
pass
file2 has functions function21 and function22
def function21():
pass
def function22():
pass
and I have the lists
file_name = ["file1", "file2", "file1"]
function_name = ["function12", "function22", "funciton12"]
I will get the list index from different function, based on that I need to call the function and get the output.
If the other function will give you a list index directly, then you don't need to deal with the function names as strings. Instead, directly store (without calling) the functions in the list:
import file1, file2
functions = [file1.function12, file2.function22, file1.function12]
And then call them once you have the index:
function[index]()
There are ways to do what is called "reflection" in Python and get from the string to a matching-named function. But they solve a problem that is more advanced than what you describe, and they are more difficult (especially if you also have to work with the module names).
If you have a "whitelist" of functions and modules that are allowed to be called from the config file, but still need to find them by string, you can explicitly create the mapping with a dict:
allowed_functions = {
'file1': {
'function11': file1.function11,
'function12': file1.function12
},
'file2': {
'function21': file2.function21,
'function22': file2.function22
}
}
And then invoke the function:
try:
func = allowed_functions[module_name][function_name]
except KeyError:
raise ValueError("this function/module name is not allowed")
else:
func()
The most advanced approach is if you need to load code from a "plugin" module created by the author. You can use the standard library importlib package to use the string name to find a file to import as a module, and import it dynamically. It looks something like:
from importlib.util import spec_from_file_location, module_from_spec
# Look for the file at the specified path, figure out the module name
# from the base file name, import it and make a module object.
def load_module(path):
folder, filename = os.path.split(path)
basename, extension = os.path.splitext(filename)
spec = spec_from_file_location(basename, path)
module = module_from_spec(spec)
spec.loader.exec_module(module)
assert module.__name__ == basename
return module
This is still unsafe, in the sense that it can look anywhere on the file system for the module. Better if you specify the folder yourself, and only allow a filename to be used in the config file; but then you still have to protect against hacking the path by using things like ".." and "/" in the "filename".
(I have a project that does something like this. It chooses the paths from a whitelist that is also under the user's control, so I have to warn my users not to trust the path-whitelist file from each other. I also search the directories for modules, and then make a whitelist of plugins that may be used, based only on plugins that are in the directory - so no funny games with "..". And I'm still worried I forgot something.)
Once you have a module name, you can get a function from it by name like:
dynamic_module = load_module(some_path)
try:
func = getattr(dynamic_module, function_name)
except AttributeError:
raise ValueError("function not in module")
At any rate, there is no reason to eval anything, or generate and import code based on user input. That is most unsafe of all.
Another alternative. This is not much safer than an eval() however.
Someone with access to the lists you read from the config file could inject malicious code in the lists you import.
I.e.
'from subprocess import call; subprocess.call(["rm", "-rf", "./*" stdout=/dev/null, stderr=/dev/null, shell=True)'
Code:
import re
# You must first create a directory named "test_module"
# You can do this with code if needed.
# Python recognizes a "module" as a module by the existence of an __init__.py
# It will load that __init__.py at the "import" command, and you can access the methods it imports
m = ["os", "sys", "subprocess"] # Modules to import from
f = ["getcwd", "exit", "call; call('do', '---terrible-things')"] # Methods to import
# Create an __init__.py
with open("./test_module/__init__.py", "w") as FH:
for count in range(0, len(m), 1):
# Writes "from module import method" to __init.py
line = "from {} import {}\n".format(m[count], f[count])
# !!!! SANITIZE THE LINE !!!!!
if not re.match("^from [a-zA-Z0-9._]+ import [a-zA-Z0-9._]+$", line):
print("The line '{}' is suspicious. Will not be entered into __init__.py!!".format(line))
continue
FH.write(line)
import test_module
print(test_module.getcwd())
OUTPUT:
The line 'from subprocess import call; call('do', '---terrible-things')' is suspicious. Will not be entered into __init__.py!!
/home/rightmire/eclipse-workspace/junkcode
I'm not 100% sure I'm understanding the need. Maybe more detail in the question.
Is something like this what you're looking for?
m = ["os"]
f = ["getcwd"]
command = ''.join([m[0], ".", f[0], "()"])
# Put in some minimum sanity checking and sanitization!!!
if ";" in command or <other dangerous string> in command:
print("The line '{}' is suspicious. Will not run".format(command))
sys.exit(1)
print("This will error if the method isnt imported...")
print(eval(''.join([m[0], ".", f[0], "()"])) )
OUTPUT:
This will error if the method isnt imported...

As pointed out by #KarlKnechtel, having commands come in from an external file is a gargantuan security risk!
I'm creating a really basic program that simulates a terminal with Python3.6, its name is Prosser(The origin is that "Prosser" sounds like "Processer" and Prosser is a command processer).
A problem that I'm having is with command import, this is, all the commands are stored in a folder called "lib" in the root folder of Prosser and inside it can have folders and files, if a folder is in the "lib" dir it can't be named as folder anymore, its name now is package(But this doesn't care for now).
The interface of the program is just a input writed:
Prosser:/home/pedro/documents/projects/prosser/-!
and the user can type a command before the text, like a normal terminal:
Prosser:/home/pedro/documents/projects/prosser/-! console.write Hello World
let's say that inside the "lib" folder exists one folder called "console" and inside it has a file called "write.py" that has the code:
class exec:
def main(args):
print(args)
As you can see the first 2 lines is like a important structure for command execution: The class "exec" is the main class for the command execution and the def "main" is the main and first function that the terminal will read and execute also pass the arguments that the user defined, after that the command will be responsible to catch any error and do what it will be created to do.
At this moment, everything is ok, but now comes the true help that I need of U guys, the command import.
Like I writed the user can type any command, and in the example above I typed a "console.write Hello World" and exists one folder called "console" and one file "write.py". The point is that the packages can be defined by a "dot", this is:
-! write Hello World
Above I only typed "write" and this says that the file is only inside the "lib" folder, it doesn't has a package to storage and separate it, so it is a Freedom command(A command that doesn't has packages or nodes).
-! console.write Hello World
Now I typed above "console.write" and this says that the file has a package or node to storage and separate it, this means that it is a Tied command(A command that has packages or nodes).
With that, a file is separated from the package(s) with a dot, the more dots you put, more folders will be navigated to find the file and proceed to the next execution.
Code
Finnaly the code. With the import statement I tryied this:
import os
import form
curDir = os.path.dirname(os.path.abspath(__file__)) # Returns the current direrctory open
while __name__ == "__main__":
c = input('Prosser:%s-! ' % (os.getcwd())).split() # Think the user typed "task.kill"
path = c[0].split('.') # Returns a list like: ["task", "kill"]
try:
args = c[1:] # Try get the command arguments
format = form.formater(args) # Just a text formatation like create a new line with "$n"
except:
args = None # If no arguments the args will just turn the None var type
pass
if os.path.exists(curDir + "/lib/" + "/".join(path) + ".py"): # If curDir+/lib/task/kill.py exists
module = __import__("lib." + '.'.join(path)) # Returns "lib.task.kill"
module.exec.main(args) # Execute the "exec" class and the def "**main**"
else:
pathlast = path[-1] # Get the last item, in this case "kill"
path.remove(path[-1]) # Remove the last item, "kill"
print('Error: Unknow command: ' + '.'.join(path) + '. >>' + pathlast + '<<') # Returns an error message like: "Error: Unknow command: task. >>kill<<"
# Reset the input interface
The problem is that when the line "module = __import__("lib." + '.'.join(path))" is executed the console prints the error:
Traceback (most recent call last):
File "/home/pedro/documents/projects/prosser/main.py", line 18, in <module>
module.exec.main(path) # Execute the "exec" class and the def "**main**"
AttributeError: module 'lib' has no attribute 'exec'
I also tried to use:
module = \_\_import\_\_(curDir + "lib." + '.'.join(path))
But it gets the same error. I think it's lighter for now. I'd like if someone help me or find some replacement of the code. :)
I think you have error here:
You have diffirent path here:
if os.path.exists(curDir + "/lib/" + "/".join(path) + ".py")
And another here, you dont have curDir:
module = __import__("lib." + '.'.join(path)) # Returns "lib.task.kill"
You should use os.path.join to build paths like this:
module = __import__(os.path.join(curdir, 'lib', path + '.py'))
I have a directory that contains my Python unit tests. Each unit test module is of the form test_*.py. I am attempting to make a file called all_test.py that will, you guessed it, run all files in the aforementioned test form and return the result. I have tried two methods so far; both have failed. I will show the two methods, and I hope someone out there knows how to actually do this correctly.
For my first valiant attempt, I thought "If I just import all my testing modules in the file, and then call this unittest.main() doodad, it will work, right?" Well, turns out I was wrong.
import glob
import unittest
testSuite = unittest.TestSuite()
test_file_strings = glob.glob('test_*.py')
module_strings = [str[0:len(str)-3] for str in test_file_strings]
if __name__ == "__main__":
unittest.main()
This did not work, the result I got was:
$ python all_test.py
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
For my second try, I though, ok, maybe I will try to do this whole testing thing in a more "manual" fashion. So I attempted to do that below:
import glob
import unittest
testSuite = unittest.TestSuite()
test_file_strings = glob.glob('test_*.py')
module_strings = [str[0:len(str)-3] for str in test_file_strings]
[__import__(str) for str in module_strings]
suites = [unittest.TestLoader().loadTestsFromName(str) for str in module_strings]
[testSuite.addTest(suite) for suite in suites]
print testSuite
result = unittest.TestResult()
testSuite.run(result)
print result
#Ok, at this point I have a result
#How do I display it as the normal unit test command line output?
if __name__ == "__main__":
unittest.main()
This also did not work, but it seems so close!
$ python all_test.py
<unittest.TestSuite tests=[<unittest.TestSuite tests=[<unittest.TestSuite tests=[<test_main.TestMain testMethod=test_respondes_to_get>]>]>]>
<unittest.TestResult run=1 errors=0 failures=0>
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
I seem to have a suite of some sort, and I can execute the result. I am a little concerned about the fact that it says I have only run=1, seems like that should be run=2, but it is progress. But how do I pass and display the result to main? Or how do I basically get it working so I can just run this file, and in doing so, run all the unit tests in this directory?
With Python 2.7 and higher you don't have to write new code or use third-party tools to do this; recursive test execution via the command line is built-in. Put an __init__.py in your test directory and:
python -m unittest discover <test_directory>
# or
python -m unittest discover -s <directory> -p '*_test.py'
You can read more in the python 2.7
or python 3.x unittest documentation.
Update for 2021:
Lots of modern python projects use more advanced tools like pytest. For example, pull down matplotlib or scikit-learn and you will see they both use it.
It is important to know about these newer tools because when you have more than 7000 tests you need:
more advanced ways to summarize what passes, skipped, warnings, errors
easy ways to see how they failed
percent complete as it is running
total run time
ways to generate a test report
etc etc
In python 3, if you're using unittest.TestCase:
You must have an empty (or otherwise) __init__.py file in your test directory (must be named test/)
Your test files inside test/ match the pattern test_*.py.
They can be inside a subdirectory under test/. Those subdirs can be named as anything, but they all need to have an __init__.py file in them
Then, you can run all the tests with:
python -m unittest
Done! A solution less than 100 lines. Hopefully another python beginner saves time by finding this.
You could use a test runner that would do this for you. nose is very good for example. When run, it will find tests in the current tree and run them.
Updated:
Here's some code from my pre-nose days. You probably don't want the explicit list of module names, but maybe the rest will be useful to you.
testmodules = [
'cogapp.test_makefiles',
'cogapp.test_whiteutils',
'cogapp.test_cogapp',
]
suite = unittest.TestSuite()
for t in testmodules:
try:
# If the module defines a suite() function, call it to get the suite.
mod = __import__(t, globals(), locals(), ['suite'])
suitefn = getattr(mod, 'suite')
suite.addTest(suitefn())
except (ImportError, AttributeError):
# else, just load all the test cases from the module.
suite.addTest(unittest.defaultTestLoader.loadTestsFromName(t))
unittest.TextTestRunner().run(suite)
This is now possible directly from unittest: unittest.TestLoader.discover.
import unittest
loader = unittest.TestLoader()
start_dir = 'path/to/your/test/files'
suite = loader.discover(start_dir)
runner = unittest.TextTestRunner()
runner.run(suite)
Well by studying the code above a bit (specifically using TextTestRunner and defaultTestLoader), I was able to get pretty close. Eventually I fixed my code by also just passing all test suites to a single suites constructor, rather than adding them "manually", which fixed my other problems. So here is my solution.
import glob
import unittest
test_files = glob.glob('test_*.py')
module_strings = [test_file[0:len(test_file)-3] for test_file in test_files]
suites = [unittest.defaultTestLoader.loadTestsFromName(test_file) for test_file in module_strings]
test_suite = unittest.TestSuite(suites)
test_runner = unittest.TextTestRunner().run(test_suite)
Yeah, it is probably easier to just use nose than to do this, but that is besides the point.
If you want to run all the tests from various test case classes and you're happy to specify them explicitly then you can do it like this:
from unittest import TestLoader, TextTestRunner, TestSuite
from uclid.test.test_symbols import TestSymbols
from uclid.test.test_patterns import TestPatterns
if __name__ == "__main__":
loader = TestLoader()
tests = [
loader.loadTestsFromTestCase(test)
for test in (TestSymbols, TestPatterns)
]
suite = TestSuite(tests)
runner = TextTestRunner(verbosity=2)
runner.run(suite)
where uclid is my project and TestSymbols and TestPatterns are subclasses of TestCase.
I have used the discover method and an overloading of load_tests to achieve this result in a (minimal, I think) number lines of code:
def load_tests(loader, tests, pattern):
''' Discover and load all unit tests in all files named ``*_test.py`` in ``./src/``
'''
suite = TestSuite()
for all_test_suite in unittest.defaultTestLoader.discover('src', pattern='*_tests.py'):
for test_suite in all_test_suite:
suite.addTests(test_suite)
return suite
if __name__ == '__main__':
unittest.main()
Execution on fives something like
Ran 27 tests in 0.187s
OK
I tried various approaches but all seem flawed or I have to makeup some code, that's annoying. But there's a convinient way under linux, that is simply to find every test through certain pattern and then invoke them one by one.
find . -name 'Test*py' -exec python '{}' \;
and most importantly, it definitely works.
In case of a packaged library or application, you don't want to do it. setuptools will do it for you.
To use this command, your project’s tests must be wrapped in a unittest test suite by either a function, a TestCase class or method, or a module or package containing TestCase classes. If the named suite is a module, and the module has an additional_tests() function, it is called and the result (which must be a unittest.TestSuite) is added to the tests to be run. If the named suite is a package, any submodules and subpackages are recursively added to the overall test suite.
Just tell it where your root test package is, like:
setup(
# ...
test_suite = 'somepkg.test'
)
And run python setup.py test.
File-based discovery may be problematic in Python 3, unless you avoid relative imports in your test suite, because discover uses file import. Even though it supports optional top_level_dir, but I had some infinite recursion errors. So a simple solution for a non-packaged code is to put the following in __init__.py of your test package (see load_tests Protocol).
import unittest
from . import foo, bar
def load_tests(loader, tests, pattern):
suite = unittest.TestSuite()
suite.addTests(loader.loadTestsFromModule(foo))
suite.addTests(loader.loadTestsFromModule(bar))
return suite
This is an old question, but what worked for me now (in 2019) is:
python -m unittest *_test.py
All my test files are in the same folder as the source files and they end with _test.
I use PyDev/LiClipse and haven't really figured out how to run all tests at once from the GUI. (edit: you right click the root test folder and choose Run as -> Python unit-test
This is my current workaround:
import unittest
def load_tests(loader, tests, pattern):
return loader.discover('.')
if __name__ == '__main__':
unittest.main()
I put this code in a module called all in my test directory. If I run this module as a unittest from LiClipse then all tests are run. If I ask to only repeat specific or failed tests then only those tests are run. It doesn't interfere with my commandline test runner either (nosetests) -- it's ignored.
You may need to change the arguments to discover based on your project setup.
Based on the answer of Stephen Cagle I added support for nested test modules.
import fnmatch
import os
import unittest
def all_test_modules(root_dir, pattern):
test_file_names = all_files_in(root_dir, pattern)
return [path_to_module(str) for str in test_file_names]
def all_files_in(root_dir, pattern):
matches = []
for root, dirnames, filenames in os.walk(root_dir):
for filename in fnmatch.filter(filenames, pattern):
matches.append(os.path.join(root, filename))
return matches
def path_to_module(py_file):
return strip_leading_dots( \
replace_slash_by_dot( \
strip_extension(py_file)))
def strip_extension(py_file):
return py_file[0:len(py_file) - len('.py')]
def replace_slash_by_dot(str):
return str.replace('\\', '.').replace('/', '.')
def strip_leading_dots(str):
while str.startswith('.'):
str = str[1:len(str)]
return str
module_names = all_test_modules('.', '*Tests.py')
suites = [unittest.defaultTestLoader.loadTestsFromName(mname) for mname
in module_names]
testSuite = unittest.TestSuite(suites)
runner = unittest.TextTestRunner(verbosity=1)
runner.run(testSuite)
The code searches all subdirectories of . for *Tests.py files which are then loaded. It expects each *Tests.py to contain a single class *Tests(unittest.TestCase) which is loaded in turn and executed one after another.
This works with arbitrary deep nesting of directories/modules, but each directory in between needs to contain an empty __init__.py file at least. This allows the test to load the nested modules by replacing slashes (or backslashes) by dots (see replace_slash_by_dot).
I just created a discover.py file in my base test directory and added import statements for anything in my sub directories. Then discover is able to find all my tests in those directories by running it on discover.py
python -m unittest discover ./test -p '*.py'
# /test/discover.py
import unittest
from test.package1.mod1 import XYZTest
from test.package1.package2.mod2 import ABCTest
...
if __name__ == "__main__"
unittest.main()
Encountered the same issue.
The solution is to add an empty __init__.py to each folder and uses python -m unittest discover -s
Project Structure
tests/
__init__.py
domain/
value_object/
__init__.py
test_name.py
__init__.py
presentation/
__init__.py
test_app.py
And running the command
python -m unittest discover -s tests/domain
To get the expected outcome

This BASH script will execute the python unittest test directory from ANYWHERE in the file system, no matter what working directory you are in: its working directory always be where that test directory is located.
ALL TESTS, independent $PWD
unittest Python module is sensitive to your current directory, unless you tell it where (using discover -s option).
This is useful when staying in the ./src or ./example working directory and you need a quick overall unit test:
#!/bin/bash
this_program="$0"
dirname="`dirname $this_program`"
readlink="`readlink -e $dirname`"
python -m unittest discover -s "$readlink"/test -v
SELECTED TESTS, independent $PWD
I name this utility file: runone.py and use it like this:
runone.py <test-python-filename-minus-dot-py-fileextension>
#!/bin/bash
this_program="$0"
dirname="`dirname $this_program`"
readlink="`readlink -e $dirname`"
(cd "$dirname"/test; python -m unittest $1)
No need for a test/__init__.py file to burden your package/memory-overhead during production.
I have no package and as mentioned on this page, this is creating issue while issing dicovery. So, I used the following solution. All the test result will be put in a given output folder.

In your test files, you need to have a main like this:
if __name__ == "__main__":
import xmlrunner
import sys
if len(sys.argv) > 1:
outputFolder = sys.argv.pop() #avoid conflic with unittest.main
else:
outputFolder = r'test-reports'
print("Report will be created and store there: " + outputFolder)
unittest.main(testRunner=xmlrunner.XMLTestRunner(output=outputFolder))
Here is my approach by creating a wrapper to run tests from the command line:
#!/usr/bin/env python3
import os, sys, unittest, argparse, inspect, logging
if __name__ == '__main__':
# Parse arguments.
parser = argparse.ArgumentParser(add_help=False)
parser.add_argument("-?", "--help", action="help", help="show this help message and exit" )
parser.add_argument("-v", "--verbose", action="store_true", dest="verbose", help="increase output verbosity" )
parser.add_argument("-d", "--debug", action="store_true", dest="debug", help="show debug messages" )
parser.add_argument("-h", "--host", action="store", dest="host", help="Destination host" )
parser.add_argument("-b", "--browser", action="store", dest="browser", help="Browser driver.", choices=["Firefox", "Chrome", "IE", "Opera", "PhantomJS"] )
parser.add_argument("-r", "--reports-dir", action="store", dest="dir", help="Directory to save screenshots.", default="reports")
parser.add_argument('files', nargs='*')
args = parser.parse_args()
# Load files from the arguments.
for filename in args.files:
exec(open(filename).read())
# See: http://codereview.stackexchange.com/q/88655/15346
def make_suite(tc_class):
testloader = unittest.TestLoader()
testnames = testloader.getTestCaseNames(tc_class)
suite = unittest.TestSuite()
for name in testnames:
suite.addTest(tc_class(name, cargs=args))
return suite
# Add all tests.
alltests = unittest.TestSuite()
for name, obj in inspect.getmembers(sys.modules[__name__]):
if inspect.isclass(obj) and name.startswith("FooTest"):
alltests.addTest(make_suite(obj))
# Set-up logger
verbose = bool(os.environ.get('VERBOSE', args.verbose))
debug = bool(os.environ.get('DEBUG', args.debug))
if verbose or debug:
logging.basicConfig( stream=sys.stdout )
root = logging.getLogger()
root.setLevel(logging.INFO if verbose else logging.DEBUG)
ch = logging.StreamHandler(sys.stdout)
ch.setLevel(logging.INFO if verbose else logging.DEBUG)
ch.setFormatter(logging.Formatter('%(asctime)s %(levelname)s: %(name)s: %(message)s'))
root.addHandler(ch)
else:
logging.basicConfig(stream=sys.stderr)
# Run tests.
result = unittest.TextTestRunner(verbosity=2).run(alltests)
sys.exit(not result.wasSuccessful())
For sake of simplicity, please excuse my non-PEP8 coding standards.
Then you can create BaseTest class for common components for all your tests, so each of your test would simply look like:
from BaseTest import BaseTest
class FooTestPagesBasic(BaseTest):
def test_foo(self):
driver = self.driver
driver.get(self.base_url + "/")
To run, you simply specifying tests as part of the command line arguments, e.g.:
./run_tests.py -h http://example.com/ tests/**/*.py
