How can I test Selenium test scripts? Or should I?

I'm working in a project with a quite large suite of tests (about 800 scenarios). Our code grew quite a lot and now I'm lo开发者_运维百科oking for ways to test some parts of our test library. Have you ever tested (parts of) your selenium scripts? How are you doing it? I thought about using some sample pages only for these tests, but it looks like a lot of work, doesn't it?

I know I can mock WebDriver, but white box testing doesn't seem quite right for me. Perhaps I have not yet grasped all the mock concepts properly. Any concerns or tips?

Here's one school of thought..

1. Create the test case manually
2. Ensure that the test case passes when a tester manually executes it
3. Create an automated selenium script to replace this test case.
4. Have a different dev or QA test the automation works correctly.
5. Integrate the automated test into some kind of nightly run.

I would not recommend having automated tests (like a unit testing or acceptence testing framework) test your selenium tests. It seems like an unnecessary layer of test automation.
