public class GroovyAssert extends Object
GroovyAssert contains a set of static assertion and test helper methods for JUnit 4+.
They augment the kind of helper methods found in JUnit 4's Assert class.
JUnit 3 users typically don't use these methods but instead,
the equivalent methods in GroovyTestCase.
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
Backwards compatibility note:
Prior to Groovy 4, GroovyAssert extended JUnit 4's Assert class.
This meant that you could statically import static methods from that class via GroovyAssert, e.g.:
import static groovy.test.GroovyAssert.assertNotNull
This is generally regarded as a code smell since inheritance is primarily to do with instance methods.
From Groovy 4, you should import such methods directly, e.g.:
import static org.junit.Assert.assertNotNull

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
}

shell - the shell to use to evaluate the scriptscript - 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.
