Though I would encourage people to skip tests while building a project but sometimes its helpful to go down this path.
Skip Unit Test
To skip the entire unit test, uses argument “-Dmaven.test.skip=true“.

 mvn install -Dmaven.test.skip=true
 mvn package -Dmaven.test.skip=true

Or define skipTests in maven-surefire-plugin.

pom.xml
   <plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-surefire-plugin</artifactId>
	<version>2.12.4</version>
	<configuration>
		<skipTests>true</skipTests>
	</configuration>
    </plugin>

Now, build the project again, the entire unit tests will be ignored.
