Use JUnit and Hamcrest in Maven

Version 4.11 and later

Up until now there were two Maven artifacts for JUnit: junit:junit-dep and junit:junit. From a Maven point-of-view only the former made sense because it did not contain the Hamcrest classes but declared a dependency to the Hamcrest Maven artifact. The latter included the Hamcrest classes which was very un-Maven-like.

From this release (4.11) on, you should use junit:junit which will be what junit:junit-dep used to. If you still reference junit:junit-dep, Maven will automatically relocate you to the new junit:junit and issue a warning for you to fix.

Version 4.10 and earlier

In your pom.xml, declare dependency used as junit-dep, and also override transitive dependency to hamcrest-core, so you can use Hamcrest full library of matchers:

<dependency>
  <groupId>org.hamcrest</groupId>
  <artifactId>hamcrest-core</artifactId>
  <version>1.3</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit-dep</artifactId>
  <version>4.10</version>
  <scope>test</scope>
</dependency>         
<dependency>
  <groupId>org.hamcrest</groupId>
  <artifactId>hamcrest-library</artifactId>
  <version>1.3</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>org.mockito</groupId>
  <artifactId>mockito-core</artifactId>
  <version>1.9.0</version>
  <scope>test</scope>
</dependency>

Discover slowest test from Surefire xml output:

The following one-liner described here.

Reports on the test times, slowest sorted to the top:

$ grep -h "<testcase" `find . -iname "TEST-*.xml"` | sed 's/<testcase time="\(.*\)" classname="\(.*\)" name="\(.*\)".*/\1\t\2.\3/' | sort -rn | head
