In fact, we all know that test cases in unittest start with test, so we want to customize, whether we can implement this requirement, this article will take you to do.
So let’s see how we do that.
First we use unittest.main() to load the running test case. Let’s click on main to see if we can jump in. Normal jump to this function. \
We can see that there is a \ that loads the test case
The default is defaultTestLoader, so LET’s see if there’s anything we want in there.
\
So here we can see it’s a class, there’s a test defined here, let’s see. Here’s how it works.

All test modules must be importable from the top level of the project.
If the start directory is not the top level directory then the top
level directory must be specified separately.
If a test package name (directory with '__init__.py') matches the
pattern then the package will be checked for a 'load_tests' function. If
this exists then it will be called with (loader, tests, pattern) unless
the package has already had load_tests called from the same discovery
invocation, in which case the package module object is not scanned for
tests - this ensures that when a package uses discover to further
discover child tests that infinite recursion does not happen.
If load_tests exists then discovery does *not* recurse into the package,
load_tests is responsible for loading all tests in the package.
The pattern is deliberately not stored as a loader attribute so that
packages can continue discovery themselves. top_level_dir is stored so
load_tests does not need to pass this argument in to loader.discover().
Paths are sorted before being imported to ensure reproducible execution
order even on filesystems with non-alphabetical ordering like ext3/4.

Copy the codeWe need to add one to the config
testname="leizi"
Copy the codeThen we can implement our function. The main changes are as follows:
1. Modify testMethodPrefix first. As you can see, when we load it again,
This is where you get the name of the test case. So once we’re done here,
When we load the test case, we also need to modify it, and after that, we can write a way to test it. \
Let’s first write a test method like this:
import unittest
from newmain import main
class testone(unittest.TestCase) :
def setUp(self) - >None: pass
def leizi1(self) :
print("leizitest")
self.assertTrue(True)
def tearDown(self) - >None: pass
def leizi2(self) :
print("leizitest")
self.assertTrue(True)
def testone(self) :
print("test test")
self.assertFalse(False)
if __name__=="__main__":
main()
