SpringJUnit4ClassRunner和SpringRunner有什么区别

Question

每当我看到一篇与Spring测试相关的博客文章时,我都会看到这些类中的任何一个,但却不了解真正的区别:

@RunWith(SpringRunner.class)
@RunWith(SpringJUnit4ClassRunner.class)

Answer 1

与javadoc没有区别:

SpringRunner是SpringJUnit4ClassRunner的别名.

ref:https://docs.spring.io/spring/docs/4.3.0.RC2_to_4.3.0.RELEASE/Spring%20Framework%204.3.0.RELEASE/org/springframework/test/context/junit4/SpringRunner.html

Answer 2

@RunWith(SpringRunner.class)告诉JUnit使用Spring的测试支持.SpringRunner是新名称SpringJUnit4ClassRunner,它只是在眼睛上更容易.

SpringRunner 仅适用于弹簧测试4.3.

SpringRunner课程延伸SpringJUnit4ClassRunner.

源代码的SpringRunnerIS

package org.springframework.test.context.junit4;

import org.junit.runners.model.InitializationError;

public final class SpringRunner extends SpringJUnit4ClassRunner {

    public SpringRunner(Class<?> clazz) throws InitializationError {
        super(clazz);
    }

}
