Convert `Assert.IsTrue` to a useful assert statement

regex.md

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.

Search Regex

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\((.*)\s*==\s*(.*)\)

Maybe tweak the casing for your language (I've done this for .NET)

Replace Regex

And do a replacement using:

Assert.AreEqual(${Expected}, ${Actual})
//Or with numbered captures
Assert.AreEqual(${2}, ${1})

//How about NUnit's Assert.That
Assert.That(${Actual}, Is.EqualTo(${Actualy}))

Run that through the Replace tool in your editor and it's all cleaned up, no more crappy assertions!
