SpringJUnit4ClassRunner 和 SpringRunner 区别是啥？

[esolve]

经常看见这俩和 RunWith 用 譬如

@RunWith(SpringRunner.class)

[kaktos]

一样的 没区别

可以参考 spring 官方文档：
https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/test/context/junit4/SpringJUnit4ClassRunner.html
https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/test/context/junit4/SpringRunner.html

第二链接里面说了“ SpringRunner is an alias for the SpringJUnit4ClassRunner.” 所以 @kaktos 说的对。

从代码中也可以看出来：
···java
public final class SpringRunner extends SpringJUnit4ClassRunner {
public SpringRunner(Class<?> clazz) throws InitializationError {
super(clazz);
}
}
