A way to add test specific params to each test using pytest

问题

I'm working on automated testing in pytest, and i'm looking for a way to read params from a config file that are specific to a test and add it to the appropriate test.

for example I would like my config.ini file to look like this:

    [Driver]
    #some genral variables

    [Test_exmpl1]
    #variables that I would like to use in Test_exmpl1
    username= exmp@gmail.com
    password= 123456

    [Test_exmpl2]
    #variables that I would like to use in Test_exmpl2
    username= exmp2@gmail.com
    password= 123456789

Now in the code I would like to be able to use these params in the correct test:

class Test_exmpl1(AppiumTestCase):

    def test_on_board(self):

        self.view = Base_LoginPageObject()
        # view = BaseLoginPageObject
        self.view = self.view.login(config.username, config.password)
        #config.username =exmp@gmail.com
        #config.password = 123456

class Test_exmpl2(AppiumTestCase):

    def test_on_board(self):

        self.view = Base_LoginPageObject()
        # view = BaseLoginPageObject
        self.view = self.view.login(config.username, config.password)
        #config.username =exmp2@gmail.com
        #config.password = 123456789

Does anyone have an idea how I should go about doing that?

回答1:

conftest.py

 @pytest.fixture()
    def before(request):
        print("request.cls name is :-- ",request.cls.__name__)
        if request.cls.__name__ == 'Test_exmpl1':
            return["username","password"]
        elif request.cls.__name__ == 'Test_exmpl2':
            return["username2","password2"]

test_module.py

import pytest

class Test_exmpl1():

    def test_on_board(self,before):
        print("IN CLASS 1")
        print("username :-- %s and password is %s"%(before[0],before[1]))

class Test_exmpl2():

    def test_on_board(self,before):
        print("IN CLASS 2")
        print("username :-- %s and password is %s"%(before[0],before[1]))

You can create a file conftest.py like as above and you can use those values in your test file of pytest.
