我正在尝试使用findOrCreateBy
来搜索对象,或者如果我找不到匹配的对象,则会实例化一个对象,但它没有按预期工作。
这就是我所拥有的:
String myBaz = "some unique string"
FooType myFooType = FooType.findByName("Large")
// The Foo table is empty, so this should give me a new Foo
Foo myFoo = Foo.findOrCreateByBazAndFooType(myBaz, myFooType)
assert myFoo.baz == myBaz
assert myFoo.fooType == myFooType // Fails because myFoo.fooType is null,
// but should be set to myFooType
我做错了什么?为什么fooType
未正确设置?这是预期的行为还是Grails中的错误?

我不确定,但看起来你试图做这个测试。 (根据你的断言)
除非您模拟域类,否则Grails框架添加的动态方法在单元测试中不可用。现在这是从另一个Question site 获取的旧grails代码,但它可能有帮助
import grails.test.GrailsUnitTestCase
class MessageControllerTests extends GrailsUnitTestCase {
def savedMessages
void setUp() {
super.setUp()
savedMessages = []
mockDomain(Message, savedMessages) //mocking the domain class
mockController(MessageController) //mocking the controller
}
void testMessageCanBeCreated() {
def messageController = new MessageController()
messageController.params.title = 'detail'
messageController.params.detail = 'some detail'
messageController.save() // executing the save action on the MessageController
assertEquals('list', messageController.redirectArgs.action)
assertEquals(1, savedMessages.size()) //assert the message has been saved
}
}
