Testing an ant Task

I had to test the SchemaCrawler ant task. Some research shows

1. Include the ant testunit jar - in a Maven project you can add a dependency such as

    <dependency>

    <groupId>org.apache.ant</groupId>

    <artifactId>ant-testutil</artifactId>

    <version>1.8.4</version>

    <scope>test</scope>

    </dependency>

1. Extend your test case from org.apache.tools.ant.BuildFileTest
2. Write a setup like

  @Override

  public void setUp()

    throws Exception

  {

    configureProject( "./build.xml" );

  }

1. Write your test cases, with the methods starting with "test" (as in the classic JUnit)

  public void testAntTask()

    throws Exception

  {

    final File testOutputFile = File.createTempFile("schemacrawler.",

                                                    ".test");

    setAntProjectProperty("outputfile", testOutputFile.getAbsolutePath());

    executeTarget("ant_task_test");

    System.out.println(getFullLog());

    System.out.println(getOutput());

    // some asserts here

  }

1. You can set properties with the utility method

  private void setAntProjectProperty(final String name, final String value)

  {

    final Project antProject = getProject();

    antProject.setProperty(name, value);

  }
