I've got a set of domain and controller classes called: Organization and OrganizationController respectively.
THe OrganizationController only has one method:
def index() {
def organizations = Organization.list()
[orgs: organizations]
}
I've tried to mock out the Domain class by 2 ways.
The first way was using the #Mock annotation, and creating the objects and saving:
void "test index"() {
given:
new Organization(name: 'JIMJIM').save()
new Organization(name: 'ABC').save()
def expected = [org: [new Organization(name: 'JIMJIM'),
new Organization(name: 'ABC')]]
when:
def actual = controller.index()
then:
actual == expected
}
That caused Oraganization.list to return an empty list. Actual returns [org: []]
I also tried using mockDomain:
void "test index"() {
given:
mockDomain(Organization, [new Organization(name: 'JIMJIM'),
new Organization(name: 'ABC')
])
def expected = [org: [new Organization(name: 'JIMJIM'),
new Organization(name: 'ABC')]]
when:
def actual = controller.index()
then:
actual == expected
}
However I still got the same result. Why is it that my domain classes are not getting mocked?
My test decoration (OrganizationControllerSpec) is the following:
#TestFor(OrganizationController)
#Mock(Organization)
#TestMixin(DomainClassUnitTestMixin)
class OrganizationControllerSpec extends Specification {
I'm using Grails 2.3.8.
The first snippet seems to be ok, but...
First of all, were the Organization objects actually created? Are all required fields provided? Please, try using save(failOnError: true) to make sure.
Moreover, in controller you have orgs, while you use org in the test. Is it only a misspell?
Also, unless you have equals method overwritten in Organization class, the objects from database are not equal to the ones you create with new operator.

I am new in unit-testing in Grails application using Spock. However I would like to ask the following question. Lets say I want to run a test for the following function testfun.
class TestFun{
boolean testfun(long userId, long orderId){
User user = User.findByUserId(userId)
if(user == null)return false
Order order = Order.findByUserAndId(user, orderId)
HashMap<String, Object> = orderContent
orderContent= order.orderContent // the order has an element orderContent for storing the elements that one user orders
if(orderContent!=null){
orderContent.put("meal",1)
order.orderContent = orderContent
return true
}
return false
}
}
The corresponding unit test in that case would be:
class TestFun extends Specification {
def setup() {
GroovySpy(User, global: true)
GroovySpy(Order, global: true)
}
def "test funtest"() {
User user = new User(2).save()
Order order = new Order(3).save()
when:
service.testfun(2,3) == result
then:
2*User.findByUserId(2) >> Mock(User)
1*Order.findByUserAndId(_ as User, 1)>> Mock(Order)
result == true
}
}
However, I think that I have to mock the order.orderContent and I do not know how to mock it. Right now the test fails, because the orderContent is null so the testfun returns false.
Can anyone help me on that?
There are several things going on here, and hopefully fixing them will help you get the test running and passing.
I can't recall for certain, but I believe GroovySpy is an old feature, that isn't used with Spock tests. Instead of using that to mock a domain class, you should be using the #Mock annotation before the class definition, to specify which domain classes you would like to mock.
While you can mock the domain classes, you'll also need to actually populate the in-memory database with those objects, either in a setup: block, or in a setup() method, if they are needed for multiple tests.
You mention creating mocks, and using the Spock Mock() method will create a mock of that object, but you don't want to use that for domain objects. It is more typically used for service classes that will be manually injected into your test class.
When saving a mock domain class, I would suggest including the parameters flush: true, failOnError: true, that way any validation that fails will be indicated immediately and on the appropriate line. Without this, you can get some strange errors to occur later in the tests.
I don't know what you're doing in the when: block, but you should not be doing an assertion with == at that point, do all of those in the then: block.
Given all of this, I think you test class should look more like this:
#Mock([User, Order])
class TestFun extends Specification {
def setup() {
// This object will have an id of 1, if you want a different id, you can either specify it, or create more objects
User user = new User(first: "john", last: "doe").save(flush: true, failOnError: true)
new Order(user: user).save(flush: true, failOnError: true)
}
def "test funtest"() {
User user = new User(2).save()
Order order = new Order(3).save()
when:
boolean result = service.testfun(1, 1)
then:
// Optionally you can just use "result" on the next line, as true will be assumed
result == true
}
}
I have a controller that on the save method calls a thread to retrieve some files. The thread has start() in a domain that has this line-
RetrievalThread retrievalThread = grailsApplication.mainContext.getBean ('retrievalThread').
In my unit test I tried this and it worked(I'll keep the other lines omitted that have no bearing right now). Without this line an error occurs saying can't get mainContext on null object,talking about grailsApplication. .
Def mainContext = Mock(ApplicationContext)
MainContext.getBean(_) >>{ name ->
return new MockRetrievalThread()}
The mock thread doesn't do anything.
This test runs fine but, any test after this fail with a null pointer exception with no real information. Looks like a bunch of background grails stuff. Is there a way to clean this up or use something better than what I'm using?
I'm sure there's a way to clean this up in a tearDown, but I think there is a better way.
1.) I would use DI rather than going through grailsApplication.mainContext.getBean; is there a reason you are doing it this way?
class MyController {
def retrievalThread
getFiles() {
return [files: retrievalThread.getFiles(params.id)]
}
}
2.a.) Using DI, you can then just set the controller's retrievalThread to a new instance of MockRetrievalThread within your test.
void "test getFiles"() {
given:
controller.retrievalThread = new MockRetrievalThread()
when:
params.id = 1
def returnedFiles = controller.getFiles()
then:
// assertions
}
2.b.) Or skip the MockRetrievalThread altogether and mock the retrievalThread bean using the mockFor method, and then set the mocked version to the injected instance in your controller.
void "test getFiles"() {
given:
def retrievalThreadMock = mockFor(RetrievalThread)
retrievalThreadMock.demand.getFiles { Integer input ->
return ['file1', 'file2', 'etc.']
}
controller.retrievalThread = retrievalThreadMock.createMock()
when:
params.id = 1
def returnedFiles = controller.getFiles()
then:
// assertions
}
You can use integration testing instead to run the entire app, in order to avoid any beans not being injected.

I have a several grails controllers that I generated and modified slightly. I'm working with the generated unit tests and getting them to pass, but I think I'm doing it the hard way. This is what I have.
package edu.liberty.swiper
import grails.test.mixin.*
import org.junit.*
#TestFor(AttendanceController)
#Mock([Attendance, Location, Reason, Person, LocCapMode, GuestContactMode, UserAccount])
class AttendanceControllerTests {
def location
def reason
void setUp() {
def capMode = new LocCapMode(description: "loc cap mode", username: "testuser").save(failOnError: true)
def guestMode = new GuestContactMode(description: "Guest Contact Mode", username: "testuser").save(failOnError: true)
location = new Location(description: "foo", locCapMode: capMode, username: "testuser", guestContactMode: guestMode).save(failOnError: true)
reason = new Reason(description: "test reason", username: "testuser").save(failOnError: true)
def person = new Person(firstName: "John", lastName: "Smith", lid: "L12345678", mi: "Q", pidm: 12345).save(failOnError: true)
def userAccount = new UserAccount(pidm: 12345, username: "testuser").save(failOnError:true)
}
def populateValidParams(params) {
assert params != null
params.personId = '12345'
params.username = "testuser"
params["location.id"] = location.id
params["reason.id"] = reason.id
params.timeIn = new Date()
}
void testIndex() {
...
}
void testList() {
...
}
void testCreate() {
...
}
void testSave() {
controller.save()
assert model.attendanceInstance != null
assert view == '/attendance/create'
response.reset()
populateValidParams(params)
controller.save()
assert response.redirectedUrl == '/attendance/show/1'
assert controller.flash.message != null
assert Attendance.count() == 1
}
void testEdit() {
...
}
...
What I'm hoping for is the ability to dynamically mock domain object, i.e. expect(Attendance.save()).andReturn(null) or expect(Attendance.save()).andReturn(testAttendance), so that I don't have to create the web of associated objects in my setUp method that are necessary to validate the domain object that is being manipulated by the controller.
Am I just looking at this all wrong? It seems like I should be able to decouple the controller logic from the validation logic., so that I can just tell the mock to tell the controller that validation passed or failed. Thanks in advance.
I don't think there is a way to tell the mock that the validation of a certain object that is handled by a controller passed or failed but I might be wrong. But as I understand it your main concern is the creation of the web of associated objects right?
Without knowing what your controller looks like I would guess that you are getting needed domain objects in your controller by ID (e.g. Location) and load a Person by pidm and so on.
To simplify the creation of needed domain objects you could use .save(validate: false).
Your setUp method could look like this:
location = new Location().save(validate: false)
reason = new Reason().save(validate: false)
If you only need objects with valid IDs this would be sufficient.
new Person(pidm: 12345).save(validate: false)
new UserAccount(username: "testuser").save(validate: false)
Set certain fields to be able to use a finder like UserAccount.findByUserName().
So if your controller does something like
location = Location.get(params["location.id"])
reason = Reason.get(params["reason.id"])
userAccount = UserAccount.findByUserName(params.username)
...
new Attendance(location: location, reason: reason, userAccount: userAccount, ...)
the aforementioned lines should be satisfactory for your setUp method.
.save(validate: false) is very useful to just set values that are really needed in your test. I hope I got the whole thing right and I could be of help.
When mocking for unit tests, you don't have to have a complete object graph with every required value to test a single domain. For example, you could have something like this..
def department = new Department(name: "Accounting").save(validate: false)
def user = new User(username: "gdboling", department: department).save()
Assuming the only 2 required fields for User are username and department, but department might have many other fields that would fail validation, this will still work if all you really need to test is User.
You still have to specify them in #Mock, you just don't have to populate every bloody field. :)
In one of my unit tests, I am having some difficulty getting a mocked method to executed. I have the following test code:
void testExample() {
def mockICFService = new MockFor(ICFService)
...
//Mock the methods
controller.metaClass.icfList = { def person ->
println "icfList"
return [new IC(conceptId:'12345')]
}
mockICFService.demand.getAllIC(1..1) { def id, def withHist, def appId ->
println "mocking service"
return new Person()
}
...
def model = controller.detail()
}
Inside of detail in my controller class I create a Person via the ICFService's getAllIC(). This part works correctly. Later in the function, however, there is a call to icfList (which is defined in the controller). Through println's I have determined that the call is still being made, although it is returning an empty array. I believe that this is because the array is populated based on data in the servletContext, but in Unit Testing there is no access to that (hence my trying to mock it out).
Does anyone know how to force the test to use the mocked version of controller.icfList instead of calling the actual method in controller?
When I try your code, what blows up for me is the mocked service, and the part that works properly is the mocked-out icfList() method. The opposite of your observation, interestingly. For what it's worth, here's what I did:
First replace new MockFor() class instantiation with the mockFor() method. Then you need to inject the mock service into the controller.
def mockICFService = mockFor(ICFService)
controller.iCFService = mockICFService.createMock()
By doing the above, only the mocked versions of icfList() and getAllIC() get called, so you are not using the servletContext at all. Check out the Grails testing documentation for more info.
I have the following as my unit test:
void testCreateDealer() {
mockForConstraintsTests(Dealer)
def _dealer= new Dealer( dealerName:"ABC",
Email:"abc-motors#global.com",
HeadOffice:"",
isBranch:false)
assertFalse _dealer.validate()
}
But when I run the test I get the following error:
No signature of method: static com.myCompany.Dealer.findByDealerNameIlike() is applicable for argument types: (java.lang.String) values: [ABC]
I use some custom constraints in my domain class. How Can I test this?
static constraints = {
dealerName(blank:false, validator:
{ val, obj ->
def similarDealer = Dealer.findByDealerNameIlike(val)
return !similarDealer || (obj.id == similarDealer.id)
}
)
Try changing mockForConstraintsTests() to mockDomain() - you're using a Dealer.findX() method in the constraint, which relies on the Dealer domain.
Incidentally, the test will still fail unless you've created a similar dealer in the setUp() method of the test class.
In unit tests, even with mockDomain, the id attribute of domain objects is not set automatically, or auto-incremented. All of the domain objects you create will have an id of null unless you explicitly set it.
Your test is probably failing because the test obj.id == similarDealer.id is true, since they both have id: null. Try setting the id attribute of your mocked dealer objects.
