pytest8-skip与xfail

 

 skip（无条件跳过测试用例）与skipif（有条件跳过测试用例）

 

# test_skip_function.py      函数级别
import pytest
import sys


@pytest.mark.skip(reason='no way of currently testing this')
def test_the_unknown():
    assert 1 == 1


@pytest.mark.skipif(sys.version_info < (3, 7), reason="requires python3.7 or higher")  # 有条件跳过测试用例
def test_function():
    assert 1 == 1

输出结果：D:\myproject\pytest_demo>pytest -qs --tb=no test_skip_function.py
ss
2 skipped in 0.02 seconds

 

# test_skip_class.py   类级别
import pytest
import sys


@pytest.mark.skipif(sys.version_info < (3, 7), reason="requires python3.6 or higher")
class TestSkipClass:
    def test_class(self):
        "requires python3.6 or higher"

输出结果：
D:\myproject\pytest_demo>pytest -qs --tb=no test_skip_class.py
s
1 skipped in 0.02 seconds

# test_skip_module.py   模块级别，跳过整个模块的测试用例
import pytest


pytestmark = pytest.mark.skip(reason='nopass')  
def test_the_unknown():
    assert 1 == 1


def test_module():
    assert 1 == 1

输出结果：
D:\myproject\pytest_demo>pytest -qs --tb=no test_skip_module.py
ss
2 skipped in 0.02 seconds

xfail

# test_xfail.py
import pytest

xfail = pytest.mark.xfail


@xfail
def test_hello():
    assert 0


@xfail(run=False)
def test_hello2():
    assert 0


@xfail("hasattr(os, 'sep')")
def test_hello3():
    assert 0


@xfail(reason="bug 110")
def test_hello4():
    assert 0


@xfail('pytest.__version__[0] != "17"')
def test_hello5():
    assert 0

输出结果：
