pytest笔记2: fixture

 1. fixture 通常是对测试方法和测试函数，测试类整个测试文件进行初始化或是还原测试环境

# 功能函数
def multiply(a, b):
    return a * b
# ------------ fixture---------------
 
def setup_module(module):
    print("======setup_module  在当前文件中所有测试用例之前=====")
 
 
def teardown_module(module):
    print("======teardown_module 在当前文件中所有测试用例之后=====")
 
 
def setup_function(function):
    print("setup_function=====>在每个测试函数之前执行")
 
 
def teardown_function(function):
    print("setup_function=====>在每个测试函数之后执行")
 
 
def setup():
    print("setup---在每个测试函数之前------>")
 
 
def teardown():
    print("teardown----在每个测试函数之后可以作用于类方法----->")
 
 
# ---------------测试用例-------------
 
def test_mult_3_4():
    print("test_mult_3_4")
    assert multiply(3, 4) == 12
 
 
def test_mult_a_4():
    print("test_mult_a_3")
    assert multiply('a', 3) == 'aaa'

没有 setup/teardown?

2.支持Test 开头的测试类

# 功能函数
def multiply(a, b):
    return a * b
 
 
class TestMultiply:
    # =====fixtures========
    @classmethod
    def setup_class(cls):
        print("setup_class=========>")
 
    @classmethod
    def teardown_class(cls):
        print("teardown_class=========>")
 
    def setup_method(self, method):
        print("setup_method----->>")
 
    def teardown_method(self, method):
        print("teardown_method-->>")
 
    def setup(self):
        print("setup----->")
 
    def teardown(self):
        print("teardown-->")
 
    # =====测试用例========
    def test_numbers_5_6(self):
        print('test_numbers_5_6')
        assert multiply(5, 6) == 30
 
    def test_strings_b_2(self):
        print('test_strings_b_2')
        assert multiply('b', 2) == 'bb'
