Class TaskDef

java.lang.Object
sbt.testing.TaskDef
All Implemented Interfaces:
Serializable
public final class TaskDef extends Object implements Serializable
A bundle of information used to request a Task from a test framework.

An array of TaskDef is passed to Runner's tasks method, which returns an array of Tasks. Each returned task, when executed, will run tests and suites determined by the test class name, fingerprints, "explicitly specified" field, and selectors of one of the passed TaskDefs.

The "Explicitly specified" field means the user supplied a complete fully qualified test name, such as with the command: 

> test-only com.mycompany.myproject.WholeNameSpec

as opposed to commands like: 

> test-only *WholeNameSpec

or simply: 

> test

The explicitlySpecified field will be true for in the first case, and false in the last two cases, because only in the first case was the fully qualified test class name completely specified by the user. The test framework can use this information to decide whether to ignore an annotation requesting a class not be discovered.

The fingerprint parameter indicates how the test suite was identified as a test suite. This tasks method may be called with TaskDefs containing the same value for testClassName but different fingerprints. For example, if both a class and its companion object were test classes, the tasks method could be passed an array containing TaskDefs with the same name but with a different value for fingerprint.isModule.

A test framework may "reject" a requested task by returning no Task for that TaskDef.

      public TaskDef(String fullyQualifiedName, Fingerprint fingerprint, boolean explicitlySpecified, Selector[] selectors)
      Constructs a new TaskDef with the given fully qualified name, fingerprint, "explicitly specified" fag, and array of selectors.
      Parameters:
      fullyQualifiedName - the fully qualified name of the test class to be run by the requested task
      fingerprint - indicates how the test suite was identified as a test suite.
      explicitlySpecified - indicates whether the test class was explicitly specified by user.
      selectors - a possibly empty array of Selectors determining suites and tests to run

  • Method Details

    • fullyQualifiedName

      public String fullyQualifiedName()
      The fully qualified name of the test class requested by this TaskDef.

    • fingerprint

      public Fingerprint fingerprint()
      The fingerprint that the test class requested by this TaskDef matches.

    • explicitlySpecified

      public boolean explicitlySpecified()
      Indicates whether or not the test class requested by this TaskDef was "explicitly specified."

      For more information on what explicitly specified means, see the main documentation for this class.

    • selectors

      public Selector[] selectors()
      One to many selectors describing the nature of the Task requested by this TaskDef.

      A Selector can indicate a direct, such as command-line, request from the user or a "rerun" of previously run tests. In the latter case, the Selectors would be taken from those passed in events of a previous run or runs.
