So I really hate when people use
Assert.IsTrue(a == b) as an assertion in a unit test (I blogged my rant) so I decided to find a way to easily convert large test files to be more normal.
You'll want to search with this:
Assert\.IsTrue\((?<Actual>.*)\s*==\s*(?<Expected>.*)\) //or if your language doesn't support named caprutes use: Assert\.IsTrue\((.*)\s*==\s*(.*)\)
