JarCastingMaven Test Time Profiler
TestTime consists of a maven plugin and extension that show the top N slowest unit tests and suites.
Single Module Projects
For single module builds, use the plugin. It will display the 5 slowest suites and tests in the log after the test phase, and it will create a testtimes.txt file in the target directory with the 20 slowest.
<build>
<plugins>
<plugin>
<groupId>ca.nanometrics.maven.plugins</groupId>
<artifactId>testtime-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<goals>
<goal>display</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
Multi-Module Projects
For multi-module builds, you can use the extension to get a single testtimes.txt file in the top level project target directory, if you want.
In the top-level pom, put:
<build>
<extensions>
<extension>
<groupId>ca.nanometrics.maven.plugins</groupId>
<artifactId>testtime-maven-extension</artifactId>
<version>1.0.0</version>
</extension>
</extensions>
</build>
You can still use the plugin above on multi-module projects too, and get individual project reports, if desired.
Properties
There are 2 system properties to control the number of results that are shown.
- testtime.loglimit - the number of slow tests/suites to show in the log
- testtime.filelimit - the number of slow tests/suites to show in the file
e.g. mvn -Dtesttime.loglimit=10 install
