pytest fixture中scope试验，包含function、module、class、session、package

上图是试验的目录结构

conftest.py：存放pytest fixture的文件

 1 import uuid
 2 import pytest
 3
 4 @pytest.fixture(scope="module")
 5 def test_module():
 6     return "module"+str(uuid.uuid4())
 7
 8 @pytest.fixture(scope="class")
 9 def test_class():
10     return "class"+str(uuid.uuid4())
11
12 @pytest.fixture(scope="function")
13 def test_function():
14     return "function"+str(uuid.uuid4())
15
16 @pytest.fixture(scope="session")
17 def test_session():
18     return "session"+str(uuid.uuid4())
19
20
21 @pytest.fixture(scope="package")
22 def test_package():
23     return "package"+str(uuid.uuid4())

test_class.py：类测试文件

 1 class Test_for_pytest_scope(object):
 2     def test_case1(self,test_module,test_class,test_function,test_session,test_package):
 3         print("testcase/test_class.py-test_case1||" + test_function)
 4         print("testcase/test_class.py-test_case1||"+test_module)
 5         print("testcase/test_class.py-test_case1||"+test_class)
 6         print("testcase/test_class.py-test_case1||" + test_session)
 7         print("testcase/test_class.py-test_case1||" + test_package)
 8
 9     def test_case2(self,test_module,test_class,test_function,test_session,test_package):
10         print("testcase/test_class.py-test_case2||" + test_function)
11         print("testcase/test_class.py-test_case2||"+test_module)
12         print("testcase/test_class.py-test_case2||"+test_class)
13         print("testcase/test_class.py-test_case2||" + test_session)
14         print("testcase/test_class.py-test_case2||" + test_package)

其它测试文件都是打印fixture的返回信息

下图是打印结果

结论：

package的试验结果和预期有些出入，其它的作用范围大小关系为   function<class<module<session

补充：翻看官方文档，发现package还处于试验阶段。
