SuperPlan(1)TaoBao Winner - Prepare the Play

SuperPlan(1)TaoBao Winner - Prepare the Play

1. Upgrade the play framework
First steps, update the play framework to the latest version. 2.1.1
>play new taobaowinner
>cd taobaowinner
>play eclipse

Run and Verify the environments.
>play
>run

It works fine.

2. Prepare the Sample
But I want to take some old projects as references. So I want to upgrade the old projects to new version.
>vi project/plugins.sbt
// Use the Play sbt plugin for Play projects
addSbtPlugin("play" % "sbt-plugin" % "2.1.0")

>vi project/Build.scala
//import PlayProject._
import play.Project._
//val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA).settings(
val main = play.Project(appName, appVersion, appDependencies).settings(

>vi project/build.properties
sbt.version=0.12.2

Once finish the configuration changes, clean and recompile the project.
>play clean
>play run
>play eclipse

Update the IDE to view the codes.

Compile Error Message
not found: object anorm
not found: value DB
not found: value get
object db is not a member of package play.api

Solution:
Change the import packages lines as follow:
import anorm._
import anorm.SqlParser._
import play.api.Play.current
import play.api.db.DB

3. Build and Learn from computer-database
Seq is a collection, Pk is the primary key of the table in anorm

I understand the Models part now. It is much easier, just directly use the SQL, scala is really the powerful language.

Try to understand the Test Case
http://www.playframework.com/documentation/2.1.1/ScalaTest

Test Your Application
Run all the test cases
play>test

Run the specified test case
play>test-only com.sillycat.MySpec

Using Specs2
http://etorreborre.github.io/specs2/

Download the sample and understand the unit tests.
>git clone https://github.com/etorreborre/specs2-test.git
>mvn eclipse:eclipse

Import to eclipse and then we can see a lot of samples.

Scala Function Test
http://www.playframework.com/documentation/2.1.1/ScalaTest
http://www.playframework.com/documentation/2.1.1/ScalaFunctionalTest

The test class should be look like this:
package unit

import org.specs2.mutable._
class HelloWorldUnitSpec extends Specification {
  "The 'Hello world' string" should {
    "contain 11 characters" in {
      "Hello world" must have size (11)
    }
    "start with 'Hello'" in {
      "Hello world" must startWith("Hello")
    }
    "end with 'world'" in {
      "Hello world" must endWith("world")
    }
  }
}


And I will run the command
play>test-only unit.HelloWorldUnitSpec

I suddenly found that my play version is 2.1.0, I plan to update that to 2.1.1.

>play clean
>play eclipse

Running multiple examples inside the same Specification
  "Computer model" should {
   
    "be retrieved by id" in {
      running(FakeApplication(additionalConfiguration = inMemoryDatabase())) {
       
        val Some(macintosh) = Computer.findById(21)
     
        macintosh.name must equalTo("Macintosh")
        macintosh.introduced must beSome.which(dateIs(_, "1984-01-24")) 
       
      }
    }
   
    "be listed along its companies" in {
      running(FakeApplication(additionalConfiguration = inMemoryDatabase())) {
       
        val computers = Computer.list()

        computers.total must equalTo(574)
        computers.items must have length(10)

      }

    }
…snip…

All the tests are based on the memory database and it is based on the SQL files.

Unit Testing Controllers
  "Application" should {
   
    "redirect to the computer list on /" in {
     
      valresult = controllers.Application.index(FakeRequest())
     
      status(result) must equalTo(SEE_OTHER)
      redirectLocation(result) must beSome.which(_ == "/computers")
     

    }
…snip…

Integration Test
  "Application" should {
   
    "work from within a browser" in {
      running(TestServer(3333), HTMLUNIT) { browser =>
        browser.goTo("http://localhost:3333/")
       
        browser.$("header h1").first.getText must equalTo("Play 2.0 sample application — Computer database")
        browser.$("section h1").first.getText must equalTo("574 computers found")
       
        browser.$("#pagination li.current").first.getText must equalTo("Displaying 1 to 10 of 574")
       
        browser.$("#pagination li.next a").click()
       
        browser.$("#pagination li.current").first.getText must equalTo("Displaying 11 to 20 of 574")
        browser.$("#searchbox").text("Apple")

        browser.$("#searchsubmit").click()
