如何在Play框架和工具的单元测试中删除创建会话的代码 [英] how can I remove codes creating session in unit test for Play framework and slick

问题描述

我正在使用play 2.0和slick.所以我为这样的模型编写单元测试.

I'm using play 2.0 and slick. so I write unit test for models like this.

describe("add") {
  it("questions be save") {
    Database.forURL("jdbc:h2:mem:test1", driver = "org.h2.Driver") withSession {
      // given
      Questions.ddl.create
      Questions.add(questionFixture)
      // when
      val q = Questions.findById(1)
      // then
      // assert!!!
    }
  }
}

它运行良好，但是在每个单元测试中都会重复以下代码片段.

it works well but following snippets is dupulicated every unit test.

Database.forURL("jdbc:h2:mem:test1", driver = "org.h2.Driver") withSession {
  Questions.ddl.create
  // test code
}

所以，我想将这段代码移动到before块中，像这样.

so, I want to move this code to before block, somthing like this.

before {
    Database.forURL("jdbc:h2:mem:test1", driver = "org.h2.Driver") withSession {
        Questions.ddl.create
    }
}

describe("add") {
  it("questions be save") {
    // given
    Questions.add(questionFixture)
    // when
    val q = Questions.findById(1)
    // then
    // assert!!!
    }
  }
}

我可以在before块中创建会话，然后在单元测试中使用会话吗?

can I create sesstion in before block and then use the session in unit test?

推荐答案

您可以使用createSession()并自行处理生命周期.我已经习惯了JUnit，但不知道您使用的测试框架的细节，但是它看起来应该像这样:

You can use createSession() and handle the lifecycle yourself. I'm used to JUnit and I don't know the specifics of the test framework you're using but it should look something like this:

// Don't import threadLocalSession, use this instead:
implicit var session: Session = _

before {
  session = Database.forURL(...).createSession()
}

// Your tests go here

after {
  session.close()
}
