I wrote the selenium test for code written to automate normalization to 1NF. Here is the pull request[0]. I was expecting the code coverage reported by coverall will increase at least 1 to 2% but it didn't. Means selenium test doesn't increase coverage ? May be because it seems to cover only the behaviour of the system.
If it is the case then how to cover the code segments which interact with database ?
Is there a way to write test cases for codes interacting with databases using normal phpUnit framework ?
