pytest skip的使用

skip跳过用例（无条件跳过，不运行用例）

使用方法：

1.使用跳过装饰器

class TestClass():
    @pytest.mark.skip(reason='no way of currently testing this')   #标记为skip后，该用例不会执行
    def test_one(self):
        print("test_one方法执行")
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

    def test_three(self):
        print("test_three方法执行")

运行结果：

2.pytest.skip(reason):在测试执行或设置期间强制跳过

import pytest

class TestClass():
    def test_one(self):
        print("test_one方法执行")
        if 1==1:
            pytest.skip("skip") #如果if语句为True时，执行到这里会跳过，方法后面的代码都不会执行
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

    def test_three(self):
        print("test_three方法执行")
        assert 3-2==1

运行结果：

 3.pytest.skip(reason,allow_module_level=True):跳过整个模块

import pytest

if 1 == 1:
    pytest.skip("skip", allow_module_level=True)

class TestClass():
    def test_one(self):
        print("test_one方法执行")
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

    def test_three(self):
        print("test_three方法执行")
        assert 3-2==1

 skip If跳过用例（有条件跳过）

1.装饰器:

@pytest.mark.skipif(sys.version_info < (3, 6), reason="requires python3.6 or higher")

 

import pytest
class TestClass():
    name='one'
    @pytest.mark.skipif(name=='one',reason="skip")   #如果装饰器里面的条件满足会跳过改方法
    def test_one(self):
        print("test_one方法执行")
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

======================================================================================================= 1 passed, 1 skipped in 0.17s =======================================================================================================

2.模块之间共享skipif标记

test_m1.py:在模块中定义一个装饰器name_one

import pytest

name = 'one'
name_one = pytest.mark.skipif(name == "one", reason='skip')  #定义装饰器name_one

class TestClass():
    @name_one   #调用装饰器
    def test_one(self):
        print("test_one方法执行")
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'

test_m2.py:导入test_m1.py模块，并调用它的name_one装饰器

import pytest
from test_cc.test_m1 import name_one

@name_one    #导入test_gy模块并调用它的装饰器name_one
def test_three():
        print("test_three方法执行")
        assert  1==1

def test_four():
        print("test_four方法执行")
        assert  'l' in 'liao'

运行test_m2.py模块的测试用例：

 3.skipif装饰类：当条件成立时，类中的所有方法都不会执行

import pytest,sys

@pytest.mark.skipif(sys.platform=='win32',reason='skip')
class TestClass():
    def test_one(self):
        print("test_one方法执行")
        assert  1==1

    def test_two(self):
        print("test_two方法执行")
        assert  'o' in 'love'
