API Documentation: | `Test`

Executes tests. Supports JUnit (3.8.x or 4.x) or TestNG tests.

### Properties

Property | Description
`allJvmArgs` | The full set of arguments to use to launch the JVM for the process. This includes arguments to define system properties, the maximum heap size, and the bootstrap classpath.
`bootstrapClasspath` | The bootstrap classpath to use for the process. The default bootstrap classpath for the JVM is used when this classpath is empty.
`classpath` | The classpath to use to execute the tests.
`debug` | Returns true if debugging is enabled for the process. When enabled, the process is started suspended and listening on port 5005.
`enableAssertions` | Returns true if assertions are enabled for the process.
`environment` | The environment variables to use for the process. Defaults to the environment of this process.
`excludes` | The exclude patterns for test execution.

### Methods

`afterSuite(closure)` | Adds a closure to be notified after a test suite has executed. A `TestDescriptor` and `TestResult` instance are passed to the closure as a parameter.
`afterTest(closure)` | Adds a closure to be notified after a test has executed. A `TestDescriptor` and `TestResult` instance are passed to the closure as a parameter.

If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.
