MUnit Runtime

The release of MUnit 1.3.0 is all about Maven usability. We have dramatically improved the way our tests run from the Maven command line, starting with the fact that we now run in a whole different VM. We’ve added a new set of features to our MUnit Maven Plugin, to allow the user to have as much control as possible, over this new VM. Thus providing support for really common use cases such as running test over applications using connectors who depend on native libraries, such as the SAP connector use case.

This is a short list of the new features:

  • Run Tests in a separate VM.

  • Allow setting argument lines from the Maven Plugin.

  • Allow to add/remove classpath entries from the Maven Plugin.

  • Allow to set environment variables from the Maven Plugin.

  • Allow to set the Mule Working Directory.

  • Allow test output redirection to a file.

  • Allow shutting down Surefire reports.
