老师，请教2个问题

Question

问题1:单条用例每一条都能执行，但是三条用例时，只执行第二条，其它用例报错：no such session。
问题2:在tearDown(self)下面，if error，保存截图，并没有生效。

第二，当你有错误的时候把self._outcome.errors:这个打印出来，和没有错误对比，这就发现问题了

Answer 2

一，没有session，说明你的driver没有初始化，或者说你case执行完把driver关闭了，把你dricer放在setuoclass里面。

  driver是放在setup(cls)下面，每次关闭driver也是在teardown(self)下面
