By default surefire configuration includes tests matching "/Test*.java", "/_Test.java" or "/_TestCase.java" pattern.
By default failsafe configuration includes tests matching "/IT*.java", "/_IT.java" or "/_ITCase.java" pattern.

Usage:
mvn install -DskipUTs : Skips Unit tests
mvn install -DskipITs : Skips Integration tests
mvn install -DskipTests : Skips both Unit and Integration Tests
