Problem: failed to create task or type testng. Cause: The name is undefined.

Question

Hi @all,

i´ve got a little problem to run a testng test. I invoke the test with a ant task which returns following error message:

BUILD FAILED
/**/build.xml:136: Problem: failed to create task or type testng
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

The ant task looks like this:

<target name="test-start" depends="test-compile" description="Runs the TestNG tests">
    <testng 
        suitename="pseudo test"
        haltOnFailure="true"
        verbose="2"
        groups="pseudoTest">
        <classpath refid="test.classpath" />
        <classfileset dir="${build.testclasses.dir}" includes="**/*.class" />
    </testng>
</target>

<path id="test.classpath">
    <fileset dir="${lib.dir}">
        <include name="**/*.jar"/>
    </fileset>
    <pathelement path="${extralib.dir}/testng-5.13.1.jar" />
    <pathelement path="${build.testclasses.dir}" />
</path>

This is the test class:

package **.pseudotest;

import org.apache.log4j.Logger;
import org.testng.annotations.Test;

public class PseudoTest {

@Test(groups = { "pseudoTest" })
public void aSingleTest() {
assert false : "The simple test failed and does not return true"; }
}

Can somebody help me to solve this problem?

Thanks

Sounds like you need to add the TestNG tasks to Ant. It doesn't know what class to run when it encounters the <testng> tag.
