在这个例子中,我们使用assert_raises来验证除以零是否会抛出ZeroDivisionError异常。如果异常未被抛出,测试将失败。 assert_called_with: 这个函数用于验证某个可调用对象是否被以预期的方式调用。例如: def test_function_call(): mock_function.assert_called_with(1, 2, 3) 在这个例子中,我们使用assert_called_with...
res = mathlib.add(a, b) assertres == expected 3.pytest进阶测试 3.1.Fixture Fixture(预置) 是 pytest 提供的一种特殊的函数,它将测试前的准备工作和解除步骤打包成一个函数,以供测试用例调用。这样做可以提高测试的可重用性和代码的可读性。 例如,我们要为数据库相关的测试都创建一个测试数据库,并在测试...
学习pytest时，总会习惯性的和unittest对比使用，自然就断言pytest和unittest也是有些区别的。
In the same file, append the tests for theadmin_command()function. The tests use a helper method that returns a sample command: Python classTestAdminCommand:defcommand(self):return["ps","aux"]deftest_no_sudo(self):result = admin_command(self.command(), sudo=False)assertresult == self.co...
Here's what a simple test function looks like:Python Copy def test_main(): assert "a string value" == "a string value" Note If you are familiar with unittest, it might be surprising to see the use of assert in the test function. We cover plain asserts in more detail later, but ...
# content of test.pydeftest(test_input):asserttest_input ==0 定义在conftest.py文件中 metafunc有5个属性,fixturenames,module,config,function,cls metafunc.parametrize() 用来实现参数化 多个metafunc.parametrize() 的参数名不能重复,否则会报错
In the failure traceback we see that the test function was called with a smtp_connection argument, the smtplib.SMTP() instance created by the fixture function. The test function fails on our deliberate assert 0. Here is the exact protocol used by pytest to call the test function this way:...
使用unittest.TestCase中的self.assert*方法下断言。 虽说这个代码量相当大,但因为这是任何测试所需要的最低限度的代码,我们最终仍然会重复写类似的代码。我们可以通过pytest直接使用Python的assert关键字来简化这个工作流程。 代码语言:javascript 复制 # test_with_pytest.py ...
