Field Detail

public static final String TEST_SCRIPT_NAME_PREFIX

Method Detail

public static void assertScript(String script)

Asserts that the script runs without any exceptions

Parameters:

script - the script that should pass without any exception thrown

protected static String genericScriptName()

Returns:

a generic script name to be used by GroovyShell#evaluate calls.

public static boolean isAtLeastJdk(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

public static boolean notYetImplemented(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:

false when not itself already in the call stack

public static Throwable shouldFail(Closure code)

Asserts that the given code closure fails when it is evaluated

Parameters:

code - the code expected to fail

Returns:

the caught exception

public static Throwable shouldFail(Class clazz, Closure code)

Asserts 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

public static Throwable shouldFail(Class clazz, 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

public static Throwable shouldFail(String script)

Asserts that the given script fails when it is evaluated

Parameters:

script - the script expected to fail

Returns:

the caught exception

public static Throwable shouldFailWithCause(Class expectedCause, 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 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
