Novice学Pytest(5)-测试用例执行状态

一、前言

  用例脚本执行完成后,每条用例都有自己的状态,常见的状态有:

  • passed:测试通过
  • failed:断言失败
  • error:用例质量不行,代码报错(eg:fixture不存在,fixture里面有报错)
  • xfail:预期失败,加了@pytest.mark.xfail()

二、error举例

  1.参数不存在

import pytest

@pytest.fixture()
def user():
    print("获取yy用户名")
    user = "liyebin01"
    assert user == "liyebin"

def test_user(user):
    assert user == "liyebin01"

  说明:user参数不存在,所以用例执行error

  2.fixture有错

import pytest

@pytest.fixture()
def user():
    print("获取yy用户名")
    user = "liyebin01"
    assert user == "liyebin"
    return user

def test_user(user):
    assert user == "liyebin01"

  说明:fixture里面断言失败,所以fixture会报错;因为test_user调用了错误的fixture,所以error表示用例有问题

三、failed举例

import pytest

@pytest.fixture()
def user():
    print("===获取yy用户名===")
    user = "liyebin01"
    return user

def test_user(user):
    assert user == "liyebin"

  说明:fixture返回的变量断言失败

import pytest

@pytest.fixture()
def user():
    print("===获取yy用户名===")
    user = "Isaymore"
    return user

def test_user(user):
    raise NameError
    assert user == "Isaymore"

  说明:用例执行期间抛出异常

  summary:

  • 测试用例的代码有异常,包括主动抛出异常或代码有异常,都算failed
  • 当测试用例调用的fixture有异常,或传入的参数有异常的时候,都算error
  • 如果一份测试报告中,error的测试用例数量越多,说明测试用例质量越差

 四、xfail举例

import pytest

# 断言装饰器
@pytest.mark.xfail(raises=ZeroDivisionError)
def test_divide():
    1 / 0

  说明:

  • 代码有异常,且和raised的异常类匹配,所以是xfail(算测试通过的一种,表示符合期望捕捉到的异常),并不算failed
  • 如果和raised的异常类不匹配,则是failed
