GroovyAssert contains a set of static assertion and test helper methods and is supposed to be a Groovy
extension of JUnit 4's Assert class. In case JUnit 3 is the choice, the GroovyTestCase
is meant to be used for writing tests based on TestCase.
GroovyAssert methods can either be used by fully qualifying the static method like
groovy.test.GroovyAssert.shouldFail { ... }
or by importing the static methods with one ore more static imports
import static groovy.test.GroovyAssert.shouldFail
import static groovy.test.GroovyAssert.assertNotNull

Asserts that the script runs without any exceptions
script - the script that should pass without any exception thrown
GroovyShell#evaluate calls.
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 for JUnit 3 is:
public void testXXX() {
if (GroovyAssert.notYetImplemented(this)) return;
... the real (now failing) unit test
}
or for JUnit 4
@Test
public void XXX() {
if (GroovyAssert.notYetImplemented(this)) return;
... the real (now failing) unit test
}

script - the script expected to failAsserts 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 matching exception is returned otherwise the method will fail.
