I have 2 directories containing tests:
project/
|
|-- test/
| |
| |-- __init__.py
| |-- test_1.py
|
|-- my_submodule/
|
|-- test/
|
|-- __init__.py
|-- test_2.py
How can I run all tests?
python -m unittest discover .
only runs test_1.py
and obviously
python -m unittest discover my_submodule
only runs test_2.py
unittest currently sees project/my_submodule as an arbitrary directory to ignore, not a package to import. Just add project/my_submodule/__init__.py to change that.
A possible solution is to write a test suite file as following:
import unittest
from test import test_1
from my_submodule.test import test_2
loader = unittest.TestLoader()
suite = unittest.TestSuite()
suite.addTest(loader.loadTestsFromModule(test_1))
suite.addTest(loader.loadTestsFromModule(test_2))
runner = unittest.TextTestRunner(verbosity=3)
result = runner.run(suite)
Save the previous file in your folder project and name it runner_test.py. The code uses 3 class of the module unittest:
TestLoader ---> see the instruction:loader = unittest.TestLoader()
TestSuite ---> see instructions:suite = unittest.TestSuite()
suite.addTest(...)
TextTestRunner ---> see instructions:runner = unittest.TextTestRunner(verbosity=3)
result = runner.run(suite)
Info about these classes can be found into the documentation.
I have written two example test files as following:
project/test/test_1.py
import unittest
class MyTestCase(unittest.TestCase):
def test_1(self):
print("test1")
self.assertEqual("test1", "test1")
if __name__ == '__main__':
unittest.main()
project/my_submodule/test/test_2.py
import unittest
class MyTestCase(unittest.TestCase):
def test_1(self):
print("test1")
self.assertEqual("test1", "test1")
if __name__ == '__main__':
unittest.main()
If you execute the following command:
> cd /path/to/folder/project
> python runner_test.py
The output of previous command (python runner_test.py) is:
test_1 (test.test_1.MyTestCase) ... test1
ok
test_2 (my_submodule.test.test_2.MyTestCase) ... test2
ok
----------------------------------------------------------------------
Ran 2 tests in 0.000s
OK
There are other ways to write a test suite: for example see this post and links connected to it.
