class DuplicateTestNameException extends StackDepthException
Exception that indicates an attempt was made to register a test that had the same name as a test already registered in the same suite. The purpose of this exception is to encapsulate information about the stack depth at which the line of code that made this attempt resides, so that information can be presented to the user that makes it quick to find the problem line of code. (In other words, the user need not scan through the stack trace to find the correct filename and line number of the offending code.)

One reason this is lazy is to delay any searching of the stack trace until it is actually needed. It will usually be needed, but not always. For example, exceptions thrown during a shrink phase of a failed property will often be
StackDepthException
s, but whosefailedCodeStackDepth
will never be used. Another reason is to remove the need to create a different exception before creating this one just for the purpose of searching through its stack trace for the proper stack depth. Still one more reason is to allow the message to contain information about the stack depth, such as the failed file name and line number.- Definition Classes
