Is it possible to run all unit test?

python unittest
pip install unittest
python unittest testsuite example
run all unit tests in folder
run all tests
run all unit tests in a directory python
what is the parent class from which a test class has to be derived for running it with unittest?
run multiple unit tests python

I have two module with two different classes and their corresponding test classes.

 foo.py
 ------
 class foo(object):
     def fooMethod(self):
         // smthg

 bar.py
 ------
 class bar(object):
     def barMethod(self):
         // smthg

 fooTest.py
 ------
 class fooTest(unittest.TestCase):
     def fooMethodTest(self):
         // smthg

 barTest.py
 ------
 class barTest(unittest.TestCase):
     def barMethodTest(self):
         // smthg

In any, test and source module, file, I erased the if __name__ == "__main__": because of increasing coherency and obeying object-oriented ideology.

Like in Java unit test, I'm looking for creating a module to run all unittest. For example,

 runAllTest.py
 -------------
 class runAllTest(unittest.TestCase):
    ?????

 if __name__ == "__main__":
    ?????

I looked for search engine but didn't find any tutorial or example. Is it possible to do so? Why? or How?

Note: I'm using eclipse and pydev distribution on windows machine.

You could create a TestSuite and run all your tests in it's if __name__ == '__main__' block:

import unittest   

def create_suite():
    test_suite = unittest.TestSuite()
    test_suite.addTest(fooTest())
    test_suite.addTest(barTest())
    return test_suite

if __name__ == '__main__':
   suite = create_suite()

   runner=unittest.TextTestRunner()
   runner.run(suite)

If you do not want to create the test cases manually look at this quesiton/answer, which basically creates the test cases dynamically, or use some of the features of the unittest module like test discovery feature and command line options ..

How do I run all Python unit tests in a directory?, This is now possible directly from unittest: unittest.TestLoader.discover. import unittest loader = unittest.TestLoader() start_dir  However when I run all tests it's completely random so class 1 method 1 runs first then class 3 method 2. This causes my tests to fail. I tried using ordered test class in visual studio however I get the following message- MStest V2 based tests cannot be used in an ordered test.

When running unit tests based on the built-in python unittest module, at the root level of your project run

python -m unittest discover <module_name>

For the specific example above, it suffices to run

python -m unittest discover .

unittest — Unit testing framework, For a list of all the command-line options: python -m unittest -h. Changed in version 3.2: In earlier versions it was only possible to run individual test methods and  You are looking for nosetests.. You might need to rename your files; I'm not sure about the pattern nose uses to find the test files but, personally, I use *_test.py.It is possible to specify a custom pattern which your project uses for test filenames but I remember being unable to make it work so I ended up renaming my tests instead.

I think you could just run the following command under the folder where your tests files are located:

python -m unittest

as mentioned here in the doc that "when executed without arguments Test Discovery is started"

4. Running & Writing Tests, To run a single test case, use the unittest module, providing the import path to the but the test suite has not reached a point where all warnings have been dealt be thorough, fast, isolated, consistently repeatable, and as simple as possible. I consistently run into issues while debugging unit tests where: The test will either continue to run after it's been cancelled or has completed, preventing it or any other test in the project from being ran again. All unit tests in the project will refresh and certain ones disappear after everything has been reloaded.

I think what you are looking for is the TestLoader. With this you can load specific tests or modules or load everything under a given directory. Also, this post has some useful examples using a TestSuite instance.

EDIT: The code I usually have in my test.py:

if not popts.tests:
    suite = unittest.TestLoader().discover(os.path.dirname(__file__)+'/tests')
    #print(suite._tests)

    # Print outline
    lg.info(' * Going for Interactive net tests = '+str(not tvars.NOINTERACTIVE))

    # Run
    unittest.TextTestRunner(verbosity=popts.verbosity).run(suite)
else:
    lg.info(' * Running specific tests')

    suite = unittest.TestSuite()

    # Load standard tests
    for t in popts.tests:
        test = unittest.TestLoader().loadTestsFromName("tests."+t)
        suite.addTest(test)

    # Run
    unittest.TextTestRunner(verbosity=popts.verbosity).run(suite)

Does two things:

  1. If -t flag (tests) is not present, find and load all tests in directory
  2. Else, load the requested tests one-by-one

Testing Python in Visual Studio Code, Many continuous integration systems also run unit tests after every build. Running the unit test early and often  Test Driven Development (TDD) & Unit Testing. Unit testing in TDD involves an extensive use of testing frameworks. A unit test framework is used in order to create automated unit tests. Unit testing frameworks are not unique to TDD, but they are essential to it. Below we look at some of what TDD brings to the world of unit testing:

With PyDev right click on a folder in Eclipse and choose "Run as-> Python unit-test". This will run all tests in that folder (the names of the test files and methods have to start with "test_".)

Writing and running tests | Django documentation, Django's unit tests use a Python standard library module: unittest . manage.py test animals.tests # Run all the tests found within the 'animals' package $ . by a given TransactionTestCase test, they must be updated to be able to run  The -c/--catch command-line option to unittest, along with the catchbreak parameter to unittest.main(), provide more friendly handling of control-C during a test run. With catch break behavior enabled control-C will allow the currently running test to complete, and the test run will then end and report all the results so far.

Testing Your Code, Each test must be able to run alone, and also within the test suite, regardless of It is a good idea to implement a hook that runs all tests before pushing code to a unittest is the batteries-included test module in the Python standard library. This means that a test run can consist of the execution of the tests of several classes if all the test queue items are inserted in the same bulk operation. The maximum number of test queue items, and hence classes, that you can insert in the Apex job queue is the greater of 500 or 10 multiplied by the number of test classes in the org.

Running the Unit Tests, The unit tests are currently excluded from the 'all' target. To build all of the tests, Running a specific test from a CxxTest test class (not possible via CTest). Debugging unit tests. 02/28/2017; 4 minutes to read; In this article. One of the most significant benefits to unit testing inside Visual Studio is the ability to debug your code during a test, and to debug the tests themselves. Unit tests are code, after all, and that code is prone to its own bugs.

Run and debug unit tests with Test Explorer, This can noticeably reduce the time taken to run all the tests. Run tests after every build  4.1.1. Unexpected Skips¶. Sometimes when running the test suite, you will see “unexpected skips” reported. These represent cases where an entire test module has been skipped, but the test suite normally expects the tests in that module to be executed on that platform.

Comments
  • I would rename the test files to 'test_foo.py' format, and run nosetests in the test directory. nose will autodiscover all the test files and test classes.
  • By far the best, most concise approach on here. Good tip, @mcguip
  • Why the the -1?
