Simplium aids the developer to create selenium based unit test that can be executed in different browsers and enviroment. With enviroment means the same test can be run against the developers own machine as well as a test machine somewhere on the network or even the production machine.

A Simplium unit tests doesn't have any reference to which URL the test is executed against as well as no reference to which browser the test should be executed in. Instead the Simplium test cases are annotated with Simplium specific annotations which allow Simplium to take control of the test cases when executed.

Simplium looks for which enviroment it is executed in (development, test or production) and based on this information Simplium will execute the test cases against different servers, against a local selenium remote control or selenium grid and execute each test in the browsers that the enviroment has specificed.
