Using specs2 and FakeApplication() to test database fails evolution inserts
playframework, playframework-2.0, scala, specs2, testing
Solution
* UPDATED *
As Jakob stated, the reason evolutions are failing is probably because the SQL written for MySQL is incompatible with H2DB. You can solve this by using a separate MySQL for testing as per the original answer, or put H2DB into MySQL compatibility mode which may fix the problem (see Fixtures in Play! 2 for Scala).
Problem
This is for Play! Framework 2.0. I'm trying to write a simple test case to ensure my user model is functioning properly and persisting data in my database. I'd like to run it in memory if possible so I can get a fresh start with every new run. The issue I have is that my evolutions run(tables are created, data is inserted, but I can't query it as being there). First, my code. ``` CREATE TABLE user_data ( id SERIAL PRIMARY KEY, user_name varchar(256) UNIQUE NOT NULL, email varchar(256) NOT NULL, password varchar(256) NOT NULL, edits int NOT NULL, reports int NOT NULL, active BOOLEAN NOT NULL); INSERT INTO user_data(user_name, email, password, edits, reports, active) VALUES ('user1', 'user1@email.com', '12345678', 0, 0, true); ``` In application.conf ``` db.default.driver=org.postgresql.Driver db.default.url="postgres://user:password@localhost:5432/ME" ``` In build.scala ``` val appDependencies = Seq( // Add your project dependencies here, "postgresql" % "postgresql" % "9.1-901-1.jdbc4" ) ``` The test code ``` class User_dataSpec extends Specification { "The Database" should { "persist data properly" in { running(FakeApplication(additionalConfiguration = inMemoryDatabase())) { //User_data.findAll().length must beEqualTo(1) //Create users User_data.create("user1", "password1", "email@test1.com") must beEqualTo(1) User_data.create("user2", "password2", "email@test2.com") must beEqualTo(2) User_data.create("user1", "password3", "email@test3.com") must beEqualTo(0) //Count users User_data.findAll().length must beEqualTo(2) //Verify users exist User_data.exists("user1") must beTrue User_data.exists("user2") must beTrue //Verify user doesn't exist User_data.exists("user3") must beFalse //Find users by ID User_data.findUser(1).get.user_name must beEqualTo("user1") User_data.findUser(2).get.user_name must beEqualTo("user2") //Fail to find users by ID User_data.findUser(3) must beNone //Find users by user_name User_data.findUser("user1").get.user_name must beEqualTo("user1") User_data.findUser("user2").get.user_name must beEqualTo("user2") //Fail to find users by user_name User_data.findUser("user3") must beNone //Authenticate users User_data.authenticate("user1", "password1") must beTrue User_data.authenticate("user2", "password2") must beTrue //Fail to authenticate users User_data.authenticate("user1", "password2") must beFalse User_data.authenticate("user3", "passwordX") must beFalse //Confirm the user was inserted properly val user = User_data.findUser("user1") user.get.user_name must beEqualTo("user1") user.get.email must beEqualTo("email@test1.com") user.get.password must beEqualTo("password1") user.get.edits must beEqualTo(0) user.get.reports must beEqualTo(0) user.get.active must beTrue } } } } ``` This code will pass as written, however it shouldn't. If I uncomment the first test case inside the running block to test that my findAll() function should be a length of 1 it will fail immediately. However, if I change this to use a persisted PostgreSQL DB on my machine, it will still fail immediately, but when I look at the PostgreSQL DB, my user_data table has the single evolution applied insert in it, and the play_evolutions table has the entry for my evolution and is marked as state = "applied" and last problem = "". Any help would be appreciated, thanks. (P.S., I am a first time poster, but will do my best to accept an answer as soon as possible for those willing to lend their help)
