The  lt scope gt  element can take 6 values  compile  provided  runtime  test  system and import   This scope is used to limit the transitivity of a dependency  and also to affect the classpath used for various build tasks      compile      This is the default scope  used if none is specified  Compile dependencies are available in all classpaths of a project  Furthermore  those dependencies are propagated to dependent projects       provided      This is much like compile  but indicates you expect the JDK or a container to provide the dependency at runtime  For example  when building a web application for the Java Enterprise Edition  you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes  This scope is only available on the compilation and test classpath  and is not transitive       runtime      This scope indicates that the dependency is not required for compilation  but is for execution  It is in the runtime and test classpaths  but not the compile classpath       test      This scope indicates that the dependency is not required for normal use of the application  and is only available for the test compilation and execution phases       system      This scope is similar to provided except that you have to provide the JAR which contains it explicitly  The artifact is always available and is not looked up in a repository       import  only available in Maven 2 0 9 or later       This scope is only used on a dependency of type pom in the  section  It indicates that the specified POM should be replaced with the dependencies in that POM s  section  Since they are replaced  dependencies with a scope of import do not actually participate in limiting the transitivity of a dependency    To answer the second part of your question      How can we use it for running test    Note that the test scope allows to use dependencies only for the test phase   Read the documentation for full details

pom dependency scope can contain   compile - available at Compile-time and Run-time provided - available at Compile-time   this dependency should be provided by outer container like OS     runtime - available at Run-time test - test compilation and run time system - is similar to provided but exposes  lt systemPath gt path some jar lt  systemPath gt  to point on  jar import - is available from Maven v2 0 9 for  lt type gt pom lt  type gt  and it should be replaced by effective dependency from this file  lt dependencyManagement  gt

Scope tag is always use to limit the transitive dependencies and availability of the jar at class path level If we don t provide any scope then the default scope will work i e  Compile
