GPAL Fluent: High-level fluent C# API

//The first step is a lambda because it is one line and naming it would add nothing. The others are methods, which is what you want once a step is worth reading on its own or is used by more than one spec. ExpectResults is where the spec earns its keep: a Then that publishes a FAILURE when the page did not do what the spec said. GPAL does not assert for you, so a Then that checks nothing passes every time.

// a step takes arguments as well, up to three, passed beside it

void SearchFor(string term)

{
