-// ExpectNow asserts that the current state of the editor matches the given

-// It can be used together with Env.Await to allow waiting on
-// simple expectations, followed by more detailed expectations tested by
-// ExpectNow. For example:
-//
-//  env.RegexpReplace("foo.go", "a", "x")
-//  env.Await(env.AnyDiagnosticAtCurrentVersion("foo.go"))
-//  env.ExpectNow(env.DiagnosticAtRegexp("foo.go", "x"))
-//
-// This has the advantage of not timing out if the diagnostic received for
-// "foo.go" does not match the expectation: instead it fails early.
