* ==================================================================
|
|
* Release Notes:
|
|
* --------------
|
|
* version 1.1
|
|
* - [3] change behaviour of verify() to NOT check unexpected invocations
|
|
* (note: it does check unexpected invocations of calls which were setup as expectations)
|
|
* - [3] added verifyAll() method which will check unexpected invocations
|
|
* - [4] added new assertion method to check for exceptions being thrown, expectThatExceptionThrown()
|
|
* - [4] added new expression to help assert the exception, is.exception({name: ... , message: ..., type: ...})
|
|
* - refactoring, ArgExpectation has been internally renamed to Expression
|
|
*
|
|
* version 1.01
|
|
* - [1] [2] bug fixes: circular references
|
|
*
|
|
* version 1.0
|
|
* - initial release
