Pytest参数选项自由执行测试用例详解（二）
运行pytest可以指定目录和文件，如果不指定，pytest会搜索当前目录及其子目录中以test_开头或以_test结尾得测试函数。我们把pytest搜索测试文件和测试用例的过程称为测试搜索（test discovery）。只要遵循pytest的命名规则，pytest就能自动搜索所有待执行的测试用例。所有的包必须要有init.py文件(在使用各种编辑器时会自动生成)
1、测试文件命名规则，test_xxx.py或xxx_test.py
2、方法、测试函数命名规则，test_xxx
3、测试类命名规则，Testxxx，并且不能带有 init 方法
Pytest参数选项在脚本中和命令行用法详解（一）
-k选项 -K EXPRESSION
使用表达式指定某个关键字的测试用例，如果某测试名是唯一的或多个测试名的前缀或后缀相同，可快速匹配，匹配范围是全局相同目录或下层目录所有（包名、文件名、类名、函数名为变量），文件名、类名、函数名，必须是test_开头或_test结尾的。
pytest.main(['-k','关键字'])
关键字包含于或等于文件名、类名、函数名，多个关键字之间用and、or、not连接
测试代码如下：
chengzi\test_04.py
import pytest
class TestClass(object):
def test_one(self):
assert 2 == 1
def test_two(self):
assert 2 == 2
def test_two2(self):
assert 2 == 2
执行匹配包名，运行了3条用例
pytest.main(['-v','-k','chengzi'])
if __name__ == '__main__':
pytest.main(['-v','-k','chengzi'])
