Python unittest 模块，expectedFailure() 实例源码
我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用unittest.expectedFailure()。

#@unittest.expectedFailure
# To my opinion it is ok if different compound scenarios work in different affected samples
# i.e. two samples can be affected but each one with a different compound pair.
