pytest 用 @pytest.mark.usefixtures("fixtureName")装饰类，可以让执行每个case前，都执行一遍指定的fixture

 

 

conftest.py

1 import pytest
2 import uuid
3 
4 @pytest.fixture()
5 def declass():
6     print("declass:"+str(uuid.uuid4()))
7     return "declass"

test_forclass.py
 1 import pytest
 2 
 3 
 4 @pytest.mark.usefixtures("declass")
 5 class TestClass(object):
 6     def test_case1(self):
 7         print("test_case1:")
 8         assert 0==0
 9 
10 
11     def test_case2(self):
12         print("test_case2:")
13         assert 0 == 0

 

 

执行结果：

可以从结果中看到每个case执行前，都执行了declass这个fixture，且每次都是重新调用。  （这种使用方法，从官方给出的例子来看，应该用于数据清理或准备比较合适。）

 

还支持引用多个fixture

conftest.py

 1 import pytest
 2 import uuid
 3 
 4 @pytest.fixture()
 5 def declass():
 6     print("declass:"+str(uuid.uuid4()))
 7     return "declass"
 8 
 9 @pytest.fixture()
10 def declass2():
11     print("declass2:"+str(uuid.uuid4()))
12     return "declass2"

test_forclass.py
 1 @pytest.mark.usefixtures("declass","declass2")
 2 class TestClass(object):
 3     def test_case1(self):
 4         print("test_case1:")
 5         assert 0==0
 6 
 7 
 8     def test_case2(self):
 9         print("test_case2:")
10         assert 0 == 0

执行结果：
