Test Driven Quotes

“The approach shown... is a common pattern for testing exception-throwing behavior with JUnit.

@Test 
public void missingValueRaisesException() throws Exception {
 try {
 new Template("${foo}").evaluate();
 fail("evaluate() should throw an exception if "
 + "a variable was left without a value!");
 } catch (MissingValueException expected) {
 }
}
