# Class FailureRecorder

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.taskdefs.optional.junit.FailureRecorder

All Implemented Interfaces:
  `Cloneable`, `EventListener`, `junit.framework.TestListener`, `BuildListener`, `JUnitResultFormatter`, `JUnitTaskMirror.JUnitResultFormatterMirror`

public class FailureRecorder extends ProjectComponent implements JUnitResultFormatter, BuildListener

Collects all failing test cases and creates a new JUnit test class containing a suite() method which calls these failed tests.

Having classes A ... D with each several testcases you could earn a new test class like

     // generated on: 2007.08.06 09:42:34,555
     import junit.framework.*;
     public class FailedTests extends TestCase {
         public FailedTests(String testname) {
             super(testname);
         }
         public static Test suite() {
             TestSuite suite = new TestSuite();
             suite.addTest(new B("test04"));
             suite.addTest(new org.D("test10"));
             return suite;
         }
     }

Because each running test case gets its own formatter, we collect the failing test cases in a static list. Because we don't have a finalizer method in the formatters "lifecycle", we register this formatter as BuildListener and generate the new java source on taskFinished event.

Since:
  Ant 1.8.0

## Constructor Details

### FailureRecorder

public FailureRecorder()

## Method Details

### setProject

### endTestSuite

public void endTestSuite(JUnitTest suite) throws BuildException
Not used The whole testsuite ended.

Specified by:

Parameters:
  `suite` - the suite.
Throws:
  `BuildException` - on error.

### addError

public void addError(junit.framework.Test test, Throwable throwable)
Add the failed test to the list.

Specified by:
  `addError` in interface `junit.framework.TestListener`
Parameters:
  `test` - the test that erred.
  `throwable` - the reason it erred.
See Also:
  - `TestListener.addError(junit.framework.Test, java.lang.Throwable)`

### addFailure

public void addFailure(junit.framework.Test test, junit.framework.AssertionFailedError error)
Add the failed test to the list.

Specified by:
  `addFailure` in interface `junit.framework.TestListener`

  `test` - the test that failed.
  `error` - the assertion that failed.
See Also:
  - `TestListener.addFailure(junit.framework.Test, junit.framework.AssertionFailedError)`
