Class: Buildr::JUnit

Inherits:
TestFramework::Java show all
Defined in:
lib/buildr/java/tests.rb

Overview

JUnit test framework, the default test framework for Java tests.

Support the following options:

  • :fork – If true/:once (default), fork for each test class. If :each, fork for each individual

    test case.  If false, run all tests in the same VM (fast, but dangerous).

  • :clonevm – If true clone the VM each time it is forked.

  • :properties – Hash of system properties available to the test case.

  • :environment – Hash of environment variables available to the test case.

  • :java_args – Arguments passed as is to the JVM.
