The problem is the tests are running without any problem when only the tests are run. However, when I execute Maven clean install then the tests are failing and the below stack trace is generated. I have tried a few of the solutions in the stackoverflow especially related to the multiple SLF4J bindings but could not completely run it error free.

The eror that I am getting is -
java.lang.ExceptionInInitializerError Caused by: org.apache.logging.log4j.LoggingException: log4j-slf4j-impl cannot be present with log4j-to-slf4j
Class path contains multiple SLF4J bindings. StaticLoggerBinder this is the root cause of the problem, to solve it you should to choice what library do you need to use for SLF4J logback-classic or slf4j-reload4j:
To set it can help you:
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId> or ch.qos.logback
<artifactId>slf4j-reload4j</artifactId> or logback-classic
</exclusion>
</exclusions>
UPDATE
On spring-boot-started dependency exclude spring-boot-starter-logging, something like this.
