Specs2 and @ Before / @ After-Methods

Question

Based on the code:

class RESTAcceptanceTest extends Specification { override def is = anonymous ^ signinOAuth def anonymous = "Something" ^ givenSomething ^ "must happen" ^ mustHappen end def signinOAuth = "Signin" ^ givenSignin ^ "works as expected" ^ userExistsInDatabase end // rest of object definitions } 

how can I make sure that before and after the code is executed before / after “anonymous” and “signinOAuth”, and the “after” method should be executed even if the test itself does not work?

Answer 1

If you use Given / When / Then steps, you can use Context to control what happens before and after each example.

 import org.specs2._ import specification._ class MySpec extends Specification { def is = "anonymous" ^ "something" ^ something ^ "must happen" ^ mustHappen ^ endp^ "OAuth"^ "signing" ^ signing ^ "works ok" ^ worksOk lazy val something: Given[Int] = (s: String) => { s.pp; 1 } lazy val mustHappen: Then[Int] = (i: Int) => (s: String) => context { s.pp; i must_== 1 } lazy val signing: Given[Int] = (s: String) => { s.pp; 2 } lazy val worksOk: Then[Int] = (i: Int) => (s: String) => context { s.pp; i must_== 2 } lazy val context = new BeforeAfter { def before = "before".pp def after = "after".pp } } 

In the above code, the apply method of the context object is used to port the code executed with before and after . Also, if you add an error to one of the examples, you will see that the "after" code is always executed.

PS: pp is a utility method, for example println to display something in the terminal at runtime. The advantage over println is that it returns its argument so you can write 1.pp must_== 1
