FizzBuzz para Dojo Groovy! Caso fuja da memoria...

AssertsSample.groovy

//Segue outros asserts que tambem podem ser utilizados nos testes unitarios do groovy.

void assertArrayEquals(Object[]expected, Object[] value) //Compares the contents and length of each array void assertLength(int length, char[] array) Convenience method for asserting the length of an array

void assertLength(int length,int[] array) //Convenience method for asserting the length of an array

void assertLength(int length,Object[] array) //Convenience method for asserting the length of an array

void assertContains(char expected,char[] array) //Verifies that a given array of chars contains an expected value

void assertContains(int expected,int[] array) //Verifies that a given array of ints contains an expected value

void assertToString(Object value,String expected) //Invokes the toString method on the provided object and compares the result with the expected string

void assertInspect(Object value,String expected) //Similar to the assertToString method, except that it calls the inspect method

void assertScript(final String script)// Attempts to run the provided script

void shouldFail(Closure code)// Verifies that the closure provided fails

void shouldFail(Class clazz,Closure code) //Verifies that the closure provided throws an exception of type clazz
