Pytest 断言

pytest 断言

断言：一个标准的用例都包含了断言，编写pytest自动化脚本的时候，也需要设置断言
assert使用
- 常用分三种 1：比较大小与是否相等 2：包含或不包含 3：验证boolean

例子

比较大小

#coding: UTF-8

import pytest

# 比较大小与是否相等

def test_assert_equal

    assert 2+2==2*2

class Test_Class():

    def test_assert_equal(self):

        assert 4==3

    def test_assert_noequal(self):

        assert 4!=3

    def test_assert_greater(self):

        assert 4>=3

if __name__ == '__main__':

    pytest.main("-v -s assert_001_equal_test.py")

包含

#coding: UTF-8

import pytest

# 测试包含或不包含

def test_in():

    a = "Hello,Jerry"

    b = "Hello"

    assert b in a 

def test_not_in():

    a = "Hello,Jerry"

    b = "Jerry"

    assert b not in a

class Test_Class():

    def test_in(self):

        a = "Hello,Jerry"

        b = "Hello"

        assert b in a 

if __name__ == '__main__':

    pytest.main("-v -s assert_002_contain_test.py")

验证boolean

#coding: UTF-8

import pytest

def check(flag):

    if flag!=0:

        return True

    else:

        return False

def test_boolean():

    assert check(1)

class Test_Boolean_Assert():

    def test_boolean(self):

        assert check(0)

if __name__ == '__main__':

    pytest.main("-v -s assert_003_boolean_test.py")
