如何仅运行测试套件中添加的测试用例而不是该类中可用的所有测试用例？

Question

I have written a Test Suite.

myTestsuite.py

import unittest
from myTestCase2 import MyTestCase2
from prime_num_validation import Prime_Num_Validation

def my_test_suite():
    suite = unittest.TestSuite()
    suite.addTest(MyTestCase2('test_greaterCheck2'))
    #To add only test case: test_greaterCheck2 from the MyTestCase2 class
    suite.addTest(Prime_Num_Validation('test_prime_check'))
    #To add only test case: test_prime_check from the MyTestCase2 class
    return suite

if __name__ == '__main__':
    runner = unittest.TextTestRunner()
    runner.run(my_test_suite())

Now when I run this using command line with: python -m unittest -v myTestsuite , It runs all the test cases from the MyTestCase2 class, which actually has 3 TC's, but we added only one out of 3 in our suite.

How should we avoid invoking all test case and executing only those which are present in the suite.

When I run this using Pycharm editor, it again executes all the test cases from MyTestCase2 .

Answer 1

You can have the marker on top of your unit test, something call xfail that will skip the test.

for example,

Below example skip test_function3()

import sys

def test_function1():

def test_function2():

@pytest.mark.skipif(sys.version_info < (3,3),
                    reason="requires python3.3")
def test_function3():

For reference please go through this site, you will find more information py.test skipif

---

the link I provided above has example of using xfail marker also.

You can use the xfail marker or create your own custom marker also. xfail is to indicate that you expect a test to fail.

You can run xfail test using following command.

pytest --runxfail

As with skipif you can also mark your expectation of a failure on a particular platform:

Example

import pytest
xfail = pytest.mark.xfail

@xfail
def test_func1():
    assert 0

@xfail(run=False)
def test_func2():
    assert 0

Answer 2

I also assumed that running python -m unittest -v myTestsuite would execute just the test cases in the defined test suites. Calling the myTestsuite.py test module directly (ie, not passing module as a parameter to the unittest library module), however, should produce the result you are after. Try running the following:

python myTestsuite

NOTE: You will need to pass the "verbosity=1" argument to the TextTestRunner function instead of using "-v" on command line (or modify myTestsuite.py to take a "-v" parameter and pass that to TextTestRunner)
