Class GroovyAssert
public class GroovyAssert extends Assert
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

Method Details- 
genericScriptNameprotected static java.lang.String genericScriptName()- Returns:
- a generic script name to be used by GroovyShell#evaluatecalls.
 
- 
assertScriptpublic static void assertScript(java.lang.String script) throws java.lang.ExceptionAsserts that the script runs without any exceptions- Parameters:
- script- the script that should pass without any exception thrown
- Throws:
- java.lang.Exception
 
- 
shouldFailAsserts that the given code closure fails when it is evaluated- Parameters:
- code- the code expected to fail
- Returns:
- the caught exception
 
- 
shouldFailAsserts that the given code closure fails when it is evaluated and that a particular type of exception is thrown.- Parameters:
- clazz- the class of the expected exception
- code- the closure that should fail
- Returns:
- the caught exception
 
- 
shouldFailWithCauseAsserts 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. - Parameters:
- expectedCause- the class of the expected exception
- code- the closure that should fail
- Returns:
- the cause
 
- 
shouldFailpublic static java.lang.Throwable shouldFail(java.lang.Class clazz, java.lang.String script)Asserts that the given script fails when it is evaluated and that a particular type of exception is thrown.- Parameters:
- clazz- the class of the expected exception
- script- the script that should fail
- Returns:
- the caught exception
 
- 
shouldFailpublic static java.lang.Throwable shouldFail(java.lang.String script)Asserts that the given script fails when it is evaluated- Parameters:
- script- the script expected to fail
- Returns:
- the caught exception
 
- 
notYetImplementedpublic static boolean notYetImplemented(java.lang.Object 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 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 }Idea copied from HtmlUnit (many thanks to Marc Guillemot). Future versions maybe available in the JUnit distribution. - Returns:
- falsewhen not itself already in the call stack
 
- 
isAtLeastJdkpublic static boolean isAtLeastJdk(java.lang.String specVersion)- Returns:
- true if the JDK version is at least the version given by specVersion (e.g. "1.8", "9.0")
- Since:
- 2.5.7
