如何使用specs2框架在liftweb中测试代码段代码

Question

I'm trying to write a Specs2 test case that will test the snippets. My snippet would look something like this:

class RegisterTest extends Specification {
  val testurl = "http:/html/register?username=liftvalues"
  val testSession = MockWeb.testS(testurl) { S.session }
  def inSession[T](a: => T): T = S.initIfUninitted(testSession) { a }
  def is = s2"""   example1 $e1   """
  val html = <form><input name="username" value="liftvalues"></input></form>
  def e1 = {
    inSession{
      register(html)
    }
  }  
  def register(in:NodeSeq):Result = {
      val username = S.param("username") //Here we are getting "Empty Value" for the S object. 
      username === "liftvalues"  and  UserSchemaTest.registerData("data")
  }
}

This test fails since S.param is Empty . What should I do to supply the snippet with a mocked Request?

So far I have looked at Unit Testing Snippets With A Logged In User and Mocking HTTP Requests , but I do not understand how to achive my goal.

Your code as-is shouldn't even compile, since among other things testSession would return a Box[LiftSession] and S.initIfUninitted requires an unboxed LiftSession . Also, that shouldn't even be needed since MockWeb.testS will initialize the session for you, see here .

I'm not super familiar with Specs2, but I believe something like this should do what you want or at least get you close:

class RegisterTest extends Specification {

  val testurl = "http://html/register?username=liftvalues"

  val html = <form><input name="username" value="liftvalues"></input></form>
  def e1 = register(html)  

  def register(in:NodeSeq):Boolean = {
      val username = S.param("username") //Here we are getting "Empty Value" for the S object. 
      username === "liftvalues" and  UserSchemaTest.registerData("data")
  }

  MockWeb.testS(testurl) {
    s2"""   example1 $e1   """
  }

}

Everything that gets called from within the MockWeb.testS block should have access to your session and request - so you'd be able to make your method calls normally.

Also, your test also looks wrong, a s2""" will probably throw an error. But, I'm not entirely sure what you are wanting it to do so I couldn't suggest an alternative.
