List of bug fixes and enhancements in 0.16.0

New and Noteworthy

New Features

  • Support for parallel test execution with JUnit >= 4.7 has been added.
    If you use Junit >= 4.7, you can now have test classes or methods executed by several threads in parallel by adding -Dparallel=classes|methods|both on the commandline or by configuring
    <plugin>
       <groupId>org.eclipse.tycho</groupId>
       <artifactId>tycho-surefire-plugin</artifactId>
       <version>${tycho-version}</version>
       <configuration>
         <parallel>classes|methods|both</parallel>
       </configuration>
    </plugin>
    

    Executing tests in parallel can be useful e.g. if you have long-running integration tests which are not CPU-bound.
    Under the hood, this feature was enabled by porting the junit4.7 surefire provider to Tycho.
