5、-x
遇到错误时停止
新增test_004.py
#!/usr/bin/python3

def test_a():
print("test_a")
assert 1 == 3
def test_b():
print('test_b')

7、-q
简化控制台的输出
pytest -q test_001.py
... [100%]
3 passed in 0.01s
8、--collect-only
罗列出当前目录下所有的测试模块，测试类及测试函数
pytest --collect-only

================================================== 2 warnings in 0.02s ===================================================
9、--lf
当一次用例执行完成后，如果其中存在失败的测试用例，那么我们可以使用此命令重新运行失败的测试用例
pytest test_004.py
============================================== 2 failed, 1 passed in 0.18s ===============================================
2个失败一个成功
pytest --lf
只会重新执行失败的2个用例
=================================================== 2 failed in 0.19s ====================================================
9、–tb=style
屏蔽测试用例输出的回溯信息，可以简化失败用例的输出信息。style可以时'auto', 'long', 'short', 'no', 'line', 'native'
pytest --tb=short test_004.py
