A re-introduction to TDD
-
I don't know where else to post this, so here goes: I've been out of touch with TDD for some time, and am very rusty. I'd appreciate some suggestions on how to TDD the method described below. The method must find a web.config file in a user supplied application directory. It must then extract and return a connection string from that config file. It returns null if for any reason the connection string isn't found, be it a bad path, no web.config, or no connection string in web.config. My initial thoughts are to write a test with setup that creates a directory and writes a web.config file with a connection string. The test would then call my method with the created path and expect a non-null value back, and my initial test run would fail because my method stub always returns null. Then, implement the method, and run the test expecting a pass. Then, as a pre-test (I forget the term), delete the created directory, and call the method expecting a null value.
