Test exception occurs when unit tests are in progress

in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;

The error is in pom.xml the dependency, look carefully at the console output and you will find that IntelliJ idea is trying to run my test case using JUNIT5.

By pom.xml discovering that I wanted to run the test case using JUnit4.12, we looked at the pom.xml discovery that junit-jupiter-api this dependency could lead to this error.

<dependency>    <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter-api</artifactId> <version>RELEASE</version></dependency>
