LarvaLight provides an easy way to specify complex assertions in your code. 

 

With a few lines in a single location in your code you can specify assertions such as: 

• Whenever a particular method A is called with a particular parameter X, another method B is thereafter always called with some related parameter Y.
• A particular method A is never called within less than 5 seconds after some method B throws an exception.
• The pattern of calling a set of methods adheres to the pattern of a particular regular expression.

When use LarvaLight?

In short, wherever you might need complex assertions: 

• during testing
• for debugging
• checking critical parts during runtime.
