AntUnit

Description

Runs Ant on targets of a build file that follow a certain naming convention. If Ant throws the special subclass of BuildException that the assertTrue task uses, consider it a failed test. Any other exception is considered a failure. If Ant completes the target without any exception, consider it a passed test.

Tests are specified via ResourceCollections.

All targets whose name starts with "test" (but not if the name is "test" exactly) are considered test cases. If a test build file contains a target named setUp, this gets executed before each test target. If it contains a target named tearDown this gets executed after each test target. Each test target is run in a fresh Ant project, i.e. each test target has a fresh set of properties and references.

So in a build file with targets setUp, tearDown, test1 and test2, antunit will run two Ant builds. One will run the targets setUp, test1 and tearDown (in that order), the other one will run setUp, test2 and tearDown. The order of those two Ant builds is not defined.

<antunit> also supports AntUnitListeners, i.e. classes that receive notifications on test runs, failures and so one. Currently two implementations of this interface are provided with this Ant library.

Log output during each antunit test case is captured by an instance of the LogCapturer class that is available via a project reference named ant.antunit.log. The published interface of that class is:

Parameters

Parameters specified as nested elements

any file system resource collection

Specifies the build files to run as tests. At least one resource is required.

any implementation of AntUnitListener

Creates a test listener that gets attached to the task.

Two listeners are part of this antlib <plainlistener/> which creates reports similar to the "plain" <formatter> of the <junit> task and <xmllistener/> which is similar to the "xml" <formatter>.

propertyset

<propertyset>s can be used to pass properties to the build files under test.

Examples

This build file snippet (from src/etc/testcases/antunit/base.xml)

  <target name="setUp">
    <echo>setup</echo>
  </target>

  <target name="test1">
    <echo>test1</echo>
  </target>

  <target name="test2">
    <echo>test2</echo>
  </target>

  <target name="Xtest3">
    <echo>test3</echo>
  </target>

  <target name="test4">
    <au:assertTrue message="test4 fails">
      <istrue value="false"/>
    </au:assertTrue>
  </target>

  <target name="test5">
    <fail message="test5 exits with error"/>
  </target>

  <target name="testLogCaptureActive">
    <au:assertReferenceSet refid="ant.antunit.log"/>
  </target>

  <target name="test">
    <fail>should be ignored</fail>
  </target>

  <target name="tearDown">
    <echo>tearDown</echo>
  </target>

together with

    <au:antunit>
      <file file="antunit/base.xml"/>
      <au:plainlistener/>
    </au:antunit>

results in output similar to
