The one time I write code before test is when I am not sure how to
achieve what I want to achieve in the app, For example I may wish to
get a particular visual layout and am not sure exactly what html I
need to generate to get the effect (due to my lack of experience). In
that case I will read docs, google and experiment with the code till
it is what I want and then knowing the html (which I make sure I now
understand) I write the tests. I then comment out the code generating
the html and check the tests fail, then put the code back in a bit at
a time to make sure the appropriate tests now pass.
What I found amazing when I started with TDD was how quickly I got the
stage of writing tests and code to develop the app, often only viewing
the app in the browser almost as an afterthought, as I was confident
it was going to work anyway.
