pytest常用Console参数：

-v 用于显示每个测试函数的执行结果
-q 只显示整体测试结果
-s 用于显示测试函数中print()函数输出
-x 在第一个错误或失败的测试中立即退出
-m 只运行带有装饰器配置的测试用例
-k 通过表达式运行指定的测试用例
-h 帮助

首先来看什么参数都没加的运行情况

class TestClass():
    def test_zne(self):
        print(1)
        assert 1==2

    def test_two(self):
        print(2)
        assert 1==2

    def test_a(self):
        print(3)
        assert 1==1

if __name__ == '__main__':
    pytest.main()

现在我也找了很多测试的朋友，做了一个分享技术的交流群，共享了很多我们收集的技术文档和视频教程。
如果你不想再体验自学时找不到资源，没人解答问题，坚持几天便放弃的感受
可以加入我们一起交流。而且还有很多在自动化，性能，安全，测试开发等等方面有一定建树的技术大牛
分享他们的经验，还会分享很多直播讲座和技术沙龙
可以免费学习！划重点！开源的！！！

-q 只显示整体测试结果

简化测试整体结果。F：代表测试失败、.：代表测试通过

import pytest
class TestClass():
    def test_zne(self):
        print(1)
        assert 1==2

    def test_two(self):
        print(2)

        assert 1==1

-s 用于显示测试函数中print()函数输出

import pytest

    def test_two(self):

-m 只运行带有装饰器配置的测试用例

用例中，第二和第三条用例加上了装饰器，装饰器最后一个单词分别为“slow” 和 “faster” ，-m 拿着两个单词去识别带这个装饰器的用例，识别到就执行，没有识别到的就不执行。

-m后面接的是表达式：['-s','-m slow or faster'] 、['-s','-m slow and faster']、['-s','-m not slow'] 这些表达式都支持。

import pytest
class TestClass():
    def test_zne(self):
        print(1)
        assert 1==2

    @pytest.mark.slow
    def test_two(self):
        print(2)
        assert 1==2

    def test_a(self):

-k 通过表达式运行指定的测试用例

通过表达式匹配用例的函数名去执行用例，not test_zne 意思是不执行“test_zne”这条用例，所以就会执行第二第三条。同理 ['-s','-k test_zne'] 表示只执行第一条。

import pytest
class TestClass():
    def test_zne(self):
        print(1)
        assert 1==2

    @pytest.mark.slow
    def test_two(self):
        print(2)
        assert 1==2

    @pytest.mark.faster
    def test_a(self):
        print(3)
        assert 1==1

-h 帮助

这才是重点，学会使用这个，剩余的都学会了

import pytest

        print(1)
        assert 1==2

    @pytest.mark.slow
    def test_two(self):
        print(2)
        assert 1==2

    @pytest.mark.faster
    def test_a(self):
        print(3)
        assert 1==1
