Foreword

Pytest can support custom tags, which can divide a web project into multiple modules, and then specify the name of the module to execute. When app automation, if you want to share a set of code between android and ios,
you can also use the mark function to indicate which are ios use cases and which are android. When running the code, specify the mark name and run it.

1. The following use case, mark test_send_http() as webtest

# content of test_server.py

import pytest

@pytest.mark.webtest
def test_send_http():
 pass # perform some webtest test for your app

def test_something_quick(): 
 pass

def test_another():
 pass

class TestClass:
 def test_method(self):
 pass< br />
if __name__ == "__main__":
 pytest.main(["-s", "test_server.py", "-m=webtest"])

Run only tests marked with webtest. When cmd is running, add the -m parameter to specify the parameter value webtest

$ pytest -v -m webtest

If you don’t want to implement the use case for marking webtest, use “not webtest”

$ pytest -v -m “not webtest”

import pytest

@pytest.mark.webtest
def test_send_http():
 pass # perform some webtest test for your app
def test_something_quick():
 pass
def test_another():

class TestClass:
 def test_method (self):

-v specified function Node id

If you want to specify a use case in the class to run under a certain .py module, such as: test_method use case in TestClass
Use cases and functions at the beginning of each test_ (or at the end of _test) The name of the (or method) is the node id of the use case. Specify the node id to run with the -v parameter

$ pytest -v test_server.py::TestClass::test_method

Of course, you can also choose to run the entire class
 < p>$ pytest -v test_server.py::TestClass

You can also select multiple nodes to run, separated by spaces between multiple nodes

$ pytest -v test_server.py::TestClass test_server.py::test_send_http

You can use the -k command line option to specify the expression that matches the case name

$ pytest -v -k http
