## TestNG Ant Task

You define the TestNG ant task as follows:

    <taskdef resource="testngtasks" classpath="testng.jar"/>

This task runs TestNG tests and is always run in a forked JVM. It accepts the following attributes:

Attribute | Description | Required
--- | --- | ---
`annotations` | Either the string "JDK" or "Javadoc". Defines which kind of annotations are used in these tests. If you use "Javadoc", you will also need to specify "sourcedir". | No. Defaults to "JDK" if you're using the JDK 5 jar and to "Javadoc" if you're using the JDK 1.4 jar.
`classfilesetref` | A reference to a FileSet structure of the test classes to be run. |
`classpath` | A PATH-like structure for the tests to be run. |
`classpathref` | A reference to a PATH-like structure for the tests to be run. |
`dataProviderThreadCount` | The number of threads to use for data providers for this run. Ignored unless the parallel mode is also specified | 1
`delegateCommandSystemProperties` | Pass the command line properties as system properties. | No. Defaults to false
`dumpCommand` | Print the TestNG launcher command. | No. Defaults to false
`enableAssert` | Enables JDK 1.4 assertion. | No. Defaults to true
`failureProperty` | The name of a property to set in the event of a failure. It is used only if the `haltonfailure` is not set. | No.
`haltonfailure` | Stop the build process if a failure has occurred during the test run. | No. Defaults to false |
`haltonskipped` | Stop the build process if there is at least on skipped test. | No. Default to false
`groups` | The list of groups to run, separated by spaces or commas. |
`excludedgroups` | The list of groups to exclude, separated by spaces or commas |
`jvm` | The JVM to use, which will be run by `Runtime.exec()` | `java`
`listeners` | A comma or space-separated list of fully qualified classes that are TestNG listeners (for example`org.testng.ITestListener` or `org.testng.IReporter)` | No.
`outputdir` | Directory for reports output. | No. Defaults to `test-output`.
`skippedProperty` | The name of a property to set in the event of a skipped test. It is used only if the `haltonskipped` is not set. | No.
`sourcedir` | A PATH-like structure for JDK 1.4 tests (using JavaDoc-like annotations) |
`sourcedirref` | A reference to a PATH-like structure for JDK 1.4 tests (using JavaDoc-like annotations). |
`suiteRunnerClass` | A fully qualified name of a TestNG starter. | No. Defaults to `org.testng.TestNG`
`parallel` | The parallel mode to use for running the tests - either methods or tests | No - if not present, parallel mode will not be selected
`threadCount` | The number of threads to use for this run. Ignored unless the parallel mode is also specified | 1
`testJar` | Path to a jar containing tests and a suite definition. |
`timeOut` | The maximum time out in milliseconds that all the tests should run under. |
`useDefaultListeners` | Whether the default listeners and reporters should be used. | Defaults to true.
`workingDir` | The directory where the ant task should change to before running TestNG. |
`xmlfilesetref` | A reference to a FileSet structure for the suite definitions to be run. |
`suitename` | Sets the default name of the test suite, if one is not specified in a suite xml file or in the source code | No. Defaults to "Ant suite"
`testname` | Sets the default name of the test, if one is not specified in a suite xml file or in the source code | No. defaults to "Ant test"

One of attributes `classpath`, `classpathref` or nested `<classpath>` must be used for providing the tests classpath.

One of the attributes `xmlfilesetref`, `classfilesetref` or nested `<xmlfileset>`, respectively `<classfileset>` must be used for providing the tests.

Note: if using JDK 1.4 one of the attributes `sourcedir`, `sourcedirref` or the nested `<sourcedir>` must be provided.

Note: using `<classfileset>` doesn't automatically adds the test classes to your classpath: you might need to repeat these classes in the classpath for the task to work.

### Nested Elements

#### classpath

The `<testng>` task supports a nested `<classpath>` element that represents a PATH-like structure.

#### bootclasspath

The location of bootstrap class files can be specified using this PATH-like structure - will be ignored if `fork` is not set.

#### xmlfileset

The suite definitions (`testng.xml`) can be passed to the task with a `FileSet` structure.

#### classfileset

TestNG can also run directly on classes, also supplied with a `FileSet` structure.

#### sourcedir

A PATH-like structure for JDK 1.4 tests using Javadoc annotations.

#### jvmarg

Additional parameters may be passed to the new VM via nested `<jvmarg>` elements. For example:

    <testng>
       <jvmarg value="-Djava.compiler=NONE" />
       <!-- ... -->
    </testng>

#### sysproperty

Use nested `<sysproperty>` elements to specify system properties required by the class. These properties will be made available to the virtual machine during the execution of the test. The attributes for this element are the same as for environment variables:

    <testng>
       <sysproperty key="basedir" value="${basedir}"/>
       <!-- ... -->
    </testng>

will run the test and make the `basedir` property available to the test.

#### reporter

An inner `<reporter>` element is an alternative way to inject a custom report listener allowing the user to set custom properties in order to fine-tune the behavior of the reporter at run-time.
The element has one `classname` attribute which is mandatory, indicating the class of the custom listener. In order to set the properties of the reporter, the `<reporter>` element can contain several nested `<property>` elements which will provide the `name` and `value` attributes as seen below:

    <testng ...>
       ...
       <reporter classname="com.test.MyReporter">
          <property name="methodFilter" value="*insert*"/>
          <property name="enableFiltering" value="true"/>
       </reporter>
       ...
    </testng>

    public class MyReporter {

      public String getMethodFilter() {...}
      public void setMethodFilter(String methodFilter) {...}
      public boolean isEnableFiltering() {...}
      public void setEnableFiltering(boolean enableFiltering) {...}
      ...
    }

You have to consider though that for the moment only a limited set of property types are supported: `String, int, boolean, byte, char, double, float, long, short`.

#### env

It is possible to specify environment variables to pass to the TestNG forked virtual machine via nested `<env>` elements. For a description of the `<env>` element's attributes, see the description in the exec task.

### Examples

#### Suite xml

    <testng classpathref="run.cp"
            outputDir="${testng.report.dir}"
            sourcedir="${test.src.dir}"
            haltOnfailure="true">

       <xmlfileset dir="${test14.dir}" includes="testng.xml"/>
    </testng>

#### Class FileSet

    <testng classpathref="run.cp"
    		outputDir="${testng.report.dir}"
    		haltOnFailure="true"M verbose="2">
    	<classfileset dir="${test.build.dir}" includes="**/*.class" />
    </testng>
