All Implemented Interfaces:

Test

public class GroovyTestCase
extends TestCase

A default JUnit TestCase in Groovy. This provides a number of helper methods plus avoids the JUnit restriction of requiring all test* methods to be void return type.

array - the array

assertContains

protected void assertContains(int expected,
                              int[] array)

Asserts that the array of ints contains a given int

Parameters:

expected - expected int

array - the array

assertToString

protected void assertToString(Object value,
                              String expected)

Asserts that the value of toString() on the given object matches the given text string

Parameters:

value - the object to be output to the console

expected - the expected String representation

assertInspect

protected void assertInspect(Object value,
                             String expected)

Asserts that the value of inspect() on the given object matches the given text string

Parameters:

value - the object to be output to the console

expected - the expected String representation

assertScript

protected void assertScript(String script)
                     throws Exception

Asserts that the script runs without any exceptions

Parameters:

script - the script that should pass without any exception thrown

Throws:

Exception

getTestClassName

protected String getTestClassName()

shouldFail

protected String shouldFail(Closure code)

Asserts that the given code closure fails when it is evaluated

Parameters:

code -

Returns:

the message of the thrown Throwable

shouldFail

protected String shouldFail(Class clazz,
                            Closure code)

protected String shouldFailWithCause(Class clazz,
                                     Closure code)

fixEOLs

protected String fixEOLs(String value)

Returns a copy of a string in which all EOLs are \n.

notYetImplemented

public static boolean notYetImplemented(TestCase caller)

Runs the calling JUnit test again and fails only if it unexpectedly runs.
This is helpful for tests that don't currently work but should work one day, when the tested functionality has been implemented.
The right way to use it is:

 public void testXXX() {
   if (GroovyTestCase.notYetImplemented(this)) return;
   ... the real (now failing) unit test
 }
 

Idea copied from HtmlUnit (many thanks to Marc Guillemot). Future versions maybe available in the JUnit distro. The purpose of providing a 'static' version is such that you can use the feature even if not subclassing GroovyTestCase.

Returns:

when not itself already in the call stack

notYetImplemented

public boolean notYetImplemented()

Convenience method for subclasses of GroovyTestCase, identical to

 GroovyTestCase.notYetImplemented(this); 

.

Returns:

when not itself already in the call stack
