unit-testing - Rspec的let的Grails等效于什么？

Question

来自Rails，在Grails中进行单元测试非常困难。在Grails中，以下内容等同于什么？
let(:some_variable) { SomeObject.new(name: 'Blabla', ...) }
我想定义一些可以在每个测试中使用的变量。此外，我希望保存对象，例如:

def "some test"() {
    // given variable1 and variable2

    then:
    response.json.size() == 2
}

因此，测试将具有两个变量，并且响应将产生这两个对象的数组，大小为2。

Answer 1

简单的情况:

@TestFor(SomeController)
class SomeControllerSpec extends Specification {
    def "some test"() {
        given:
            def var1 = new SomeObject(name:"AAA").save(flush:true)
            def var2 = new SomeObject(name:"BBB").save(flush:true)
        when:
            controller.someAction() 
            // assuming someAction fetches the SomeObject instances 
            // and marshals a JSON Response
        then:
            controller.response.json.size() == 2
    }
}

也许:

@TestFor(SomeController)
class SomeControllerSpec extends Specification {

    // var1 and var2 are saved to the DB, and persist across all
    // the tests in this specification
    def var1 = new SomeObject(name:"AAA").save(flush:true)
    def var2 = new SomeObject(name:"BBB").save(flush:true)

    def "some test"() {
        when:
            controller.someAction() 
        then:
            controller.response.json.size() == 2
    }
}
