What is the difference between SpringJUnit4ClassRunner and SpringRunner
There is no difference, from the javadoc:
SpringRunner is an alias for the SpringJUnit4ClassRunner.
@RunWith(SpringRunner.class) tells JUnit to run using Spring’s testing support. SpringRunner is the new name for SpringJUnit4ClassRunner, it’s just a bit easier on the eye.
SpringRunner is only available on spring-test 4.3.
SpringRunner class extends SpringJUnit4ClassRunner.
Source code of SpringRunner is
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); }}
