I have a class called
class Trainer {
def showPeople(xhtml : Group) : NodeSeq = {
val user : User = User.currentUser.open_!
...
}
}
I then want to write a unit test to test that returns proper xml.
The test is written as so
def testValue() = {
val xml =
<xml:group>
<tr>
<td>
<p:fullName>My Name</p:fullName>
</td>
<td>
<p:style>Fighter Style</p:style>
</td>
<td>
<p:weight>Weight</p:weight>
</td>
</tr>
</xml:group>
val trainer = new Trainer()
val output = trainer.showPeople(xml)
()
}
The User object inherits from MegaProtoUser.
The problem is I am not sure how to create a mock user and sign them
in.
I have tried in my unit test
override def setUp : Unit = {
val user = User.create
user.firstName("XXX")
user.lastName("YYY")
user.save
User.logUserIn(user)
}
The mock user log-in *seems* to work fine but when
User.currentUser.open_! is called it throws an exception on trying to
open an empty box.
So either how do I do this or how do others do this type of testing.
I am sure I am missing something simple.
Thanks,
ryan

Using Specs 1.6:
object HelloWorldTestSpecs extends Specification {val session = new LiftSession("", randomString(20), Empty)val stableTime = nowoverride def executeExpectations(ex: Examples, t: =>Any): Any = {S.initIfUninitted(session) {... put your User init here. The User.logUserIn will be within the context of a session and thus session (and request) vars will be valid}}
"HelloWorld Snippet" should {"Put the time in the node" in {... do testing here}}}
Hope this helps.

Hi Ryan,
It looks like you're currently using a JUnit TestCase. If you want an
easier port to something that would work you could use a ScalaTest
Suite like this:
import org.scalatest.Suite
class YourSuite extends Suite {
val session = new LiftSession("", randomString(20), Empty)
val stableTime = now
override def withFixture(test: NoArgTest) {
S.initIfUninitted(session) {
}
}
def testValue() {
}
}
A Suite considers methods that start with "test" as tests, like JUnit
3, except they don't need to result in Unit so you don't need an extra
() at the end. The withFixture method is an alternative to
beforeEach/afterEach, which are like JUnit 3's setUp/tearDown methods.
Each test gets passed as a function to withFixture, which is
responsible for executing the test by invoking the function. In this
case, it is executed in the context created by S. initIfUninitted.
This is ScalaTest 1.0, which is available as a SNAPSHOT right now but
should be released proper a week from Monday.

Bill,

Thanks for posting this. I am, by experience (I started using it, I can use it enough to write basic tests, I know no more) using Specs. I would welcome and encourage some sample tests in Lift archetypes that use ScalaTest. I want to make sure that folks who pick up Lift get to experience ScalaTest as well as Specs... that way, folks who have a better understanding of tests can make better choices.
Thanks,
David

Hi David,
Thanks. I appreciate that. I was actually already planning to request
getting some ScalaTest examples in the Lift archetypes right after
ScalaTest 1.0 comes out (on Oct 12, if all goes as planned), and have
already arranged with David Bernard to put ScalaTest examples into
simple-archetype-simple.
I think it is great that we have three decent Scala-specific testing
tools already, specs, ScalaTest, and ScalaCheck, plus the trusty Java
tools JUnit and TestNG. People have a lot of choice, so it is good
that the archetypes would show some of the options. I would also
suggest we include a ScalaCheck example in the archetypes as well. I
can use ScalaCheck from one of the ScalaTest examples I submit if you
like that idea. The downside is that it would add one more dependency,
but really I think people should find out about ScalaCheck.

Awesome!!! Thanks guys for the help. It now works.
I put a how-to wiki document up on github. For me this was one of
those times where my google searches did not seem to turn up anything
fruitful, so I thought this how-to would be helpful. If it is not
helpful, then no hard feelings if the page is deleted. I just wanted
to give back.

You did *the right thing*. I owe you a beer (or other food or beverage of your choice)!

Hi,
I am working at the moment on a small lift demo app and I've added
some enhancements to specs in order to ease the testing inside a
session.
To use those functionalities, you need specs-1.6.1-SNAPSHOT (http://
www.scala-tools.org/repo-snapshots/org/scala-tools/testing/specs/1.6.1-SNAPSHOT).
Here are the specification and traits that I use to test the JPA
requests to save a User in the database:
// First I create Mocks for the lift session
import javax.servlet.http._
import net.liftweb.http.{ S, Req, LiftSession }
import org.specs.mock.Mockito
trait MockRequest extends Mockito { this: Specification =>
var request = mock[Req]
var httpRequest = mock[HttpServletRequest]
var session = mock[LiftSession]
def createMocks: Unit = {
request = mock[Req]
httpRequest = mock[HttpServletRequest]
session = mock[LiftSession]
request.request returns httpRequest
}
// this method can be used to executed any action inside a mocked
session
def inSession(f: =>Any) { S.init(request, session) { f } }
def unsetParameter(name: String) { request.param(name) returns
None }
def setParameter(name: String, value: String) { request.param
(name) returns Some(value) }
}
// Context creation for the specification
//
// This "Specification context" specifies the User table must be
cleaned up before each example.
// It also makes sure that the example expectations are executed in a
mocked session
// see http://code.google.com/p/specs/wiki/DeclareSpecifications#Specification_context_(_from_1.6.1_)
for more information
object DatabaseContext extends Specification with Contexts with
MockRequest {
val setup = new SpecContext {
beforeExample(inSession(Users.createQuery("delete
User").executeUpdate)) // delete the User table before each example
aroundExpectations(inSession(_)) // execute each example inside a
mocked session
}
}
// and finally the specification itself
import org.specs._
import org.specs.specification._
class UserSpec extends SpecificationWithJUnit with MockRequest with
Contexts {
DatabaseContext.setup(this) // set the specification context on this
specification
"A Users repository" can {
"create a user" in {
val eric = User("etorreborre", "password", "Eric")
Users.mergeAndFlush(eric) // the Users object is a LocalEMF
with RequestVarEM so it needs a session
Users.find(classOf[User], "etorreborre") must_== Some(eric)
}
}
"A Users repository" should {
"throw an exception if the user name has a length < 5" in {
Users.merge(User("e", "password", "Eric")) must throwAn
[Exception]
}
}
}
I hope this helps too, please ask if you have any questions.

Eric you may want to add a specs version.

Sweet!!! Thanks Bill for adding a ScalaTest version. I wanted to but
just did not find the time yesterday. I also don't know ScalaTest very
well but will be working with it shortly.
