[Java] Class GroovyTestCase

java.lang.Object
  junit.framework.TestCase
      groovy.util.GroovyTestCase

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.

 GroovyTestCase.notYetImplemented(this); 

TEST_SCRIPT_NAME_PREFIX

public static final String TEST_SCRIPT_NAME_PREFIX

log

protected static Logger log

assertArrayEquals

protected void assertArrayEquals(Object[] expected, Object[] value)

Asserts that the arrays are equivalent and contain the same values

Parameters:

expected

value

assertContains

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

Asserts that the array of characters contains a given char

Parameters:

expected - expected character to be found

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

assertEquals

public static void assertEquals(String message, Object expected, Object actual)

assertEquals

public static void assertEquals(Object expected, Object actual)

assertEquals

public static void assertEquals(String expected, String actual)

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

assertLength

protected void assertLength(int length, char[] array)

Asserts that the array of characters has a given length

Parameters:

length - expected length

array - the array

assertLength

protected void assertLength(int length, int[] array)

Asserts that the array of ints has a given length

Parameters:

length - expected length

array - the array

assertLength

protected void assertLength(int length, Object[] array)

Asserts that the array of objects has a given length

Parameters:

length - expected length

array - the array

assertScript

protected void assertScript(String script)

Asserts that the script runs without any exceptions

Parameters:

script - the script that should pass without any exception thrown

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

fixEOLs

protected String fixEOLs(String value)

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

getMethodName

public String getMethodName()

getName

public String getName()

Overload the getName() method to make the test cases look more like AgileDox (thanks to Joe Walnes for this tip!)

getTestClassName

protected String getTestClassName()

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

shouldFail

protected String shouldFail(Closure code)

Asserts that the given code closure fails when it is evaluated.

Parameters:

code - the closure that should fail

Returns:

the message of the thrown Throwable

shouldFail

protected String shouldFail(Class clazz, Closure code)

Asserts that the given code closure fails when it is evaluated and that a particular exception type is thrown.

Parameters:

clazz - the class of the expected exception

code - the closure that should fail

Returns:

the message of the expected Throwable

shouldFailWithCause

protected String shouldFailWithCause(Class clazz, Closure code)

Asserts that the given code closure fails when it is evaluated and that a particular exception type can be attributed to the cause. The expected exception class is compared recursively with any nested exceptions using getCause() until either a match is found or no more nested exceptions exist.

If a match is found the error message associated with the matching exception is returned. If no match was found the method will fail.

Parameters:

clazz - the class of the expected exception

code - the closure that should fail

Returns:

the message of the expected Throwable
