前言
- pytest.mark.skip可以标记无法在某些平台上运行的测试功能,
- 或者您希望失败的测试功能希望满足某些条件才执行某些测试用例,否则pytest会跳过运行该测试用例
- 实际常见场景:跳过非windows平台上的仅windows测试,或者跳过依赖于当前不可用的外部资源(例如数据库)的测试
@pytest.mark.skip
跳过执行测试用例,有可选参数reason:跳过的原因,会在执行结果中打印

执行结果
知识点
- @pytest.mark.skip可以加在函数上,类上,类方法上
- 如果加在类上面,类里面的所有测试用例都不会执行
- 以上小案例都是针对:整个测试用例方法跳过执行,如果想在测试用例执行期间跳过不继续往下执行呢?
pytest.skip()函数基础使用
作用:在测试用例执行期间强制跳过不再执行剩余内容
类似:在python的循环里面,满足某些条件则break 跳出循环

def test_function(): n = 1 while true : print(f "这是我第{n}条用例" ) n += 1 if n == 5: pytest.skip( "我跑五次了不跑了" ) |
执行结果
pytest.skip(msg="",allow_module_level=false)
当allow_module_level=true时,可以设置在模块级别跳过整个模块

跳过标记
- 可以将pytest.mark.skip和pytest.mark.skipif赋值给一个标记变量
- 在不同模块之间共享这个标记变量
- 若有多个模块的测试用例需要用到相同的skip或skipif,可以用一个单独的文件去管理这些通用标记,然后适用于整个测试用例集

pytest.importorskip( modname: str, minversion: optional[str] = none, reason: optional[str] = none )
作用:如果缺少某些导入,则跳过模块中的所有测试
参数列表
- modname:模块名
- minversion:版本号
- reasone:跳过原因,默认不给也行

pexpect = pytest.importorskip( "pexpect" , minversion= "0.3" ) @pexpect def test_import(): print( "test" ) |
执行结果一:如果找不到module
skipped: could not import 'pexpect': no module named 'pexpect'
collected 0 items / 1 skipped
执行结果一:如果版本对应不上
skipped: module 'sys' has __version__ none, required is: '0.3'
collected 0 items / 1 skipped
