Problem: slf4j: failed to load class “org. Slf4j. Impl. Staticloggerbinder” error occurs when creating Maven project with idea for unit test

solution: add dependency in pom.xml. Because it is in the test environment, the scope tag is test. If it is running in main, you can change test.

<dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.7.25</version>
            <scope>test</scope>
        </dependency>
