The RunInMem extension method takes a fully configured AppRunner instance and runs it in memory.

public void Checkout_NewBranch_WithoutBranchFlag_Fails()
    var result = new AppRunner<Git>()
        .RunInMem("checkout lala");

    result.OutputShouldBe("error: pathspec 'lala' did not match any file(s) known to git" );
