I'm trying to do a test on controller that uses 3 Domains and a service to perform persistence, when I use these values in view he is saving normally, but in my unit test does not pass validation, I do not understand why . If someone who has been there can help me, I do not know if the Mock I'm doing is correct, I followed the examples in the documentation oficial .
thats the error message:
junit.framework.AssertionFailedError: expected:<1> but was:<0>
Thats my code for Test:
#TestFor(UsuarioController)
#Mock([SecRole, UsuarioService, Usuario, Cliente, Secuser])
#TestMixin(ControllerUnitTestMixin)
class UsuarioTests {
private def usuarioCommand
private def service
#Before
void setUp() {
usuarioCommand = mockCommandObject(UsuarioCommand)
service = mockFor(UsuarioService)
}
#Test
void testCadastrarUsuarioCorreto() {
usuarioCommand.perfil = 2
usuarioCommand.nome = "Michael Swaltz"
usuarioCommand.cpf = "381.453.718-13"
usuarioCommand.email = "michael.s#mail.com"
usuarioCommand.login = "login"
usuarioCommand.senha = "senha"
usuarioCommand.senhaRepeat = "senha"
assertTrue( usuarioCommand.validate() );
controller.usuarioService = service
controller.create(usuarioCommand)
assertEquals(1, Usuario.count())
}
This is my controller action:
def create = { UsuarioCommand usuario ->
if(!params.create) return
if(!usuario.hasErrors()) {
def secuser = new Secuser(username: usuario.login, password: usuario.senha, senha: usuario.senhaRepeat, enabled: true)
def user = new Usuario(nomeUsuario: usuario.nome, email: usuario.email, cpf: usuario.cpf, idNivelAcesso: usuario.perfil)
def cliente = Cliente.findByUsuario( session.usuario )
user.setIdCliente(cliente)
def secrole = SecRole.get( usuario.perfil )
try{
usuarioService.save(user, secuser, secrole)
flash.message = "Usuário ${usuario.nome} cadastrado.".toString()
redirect (action: 'list')
}catch(ValidationException ex) {
StringBuilder mensagem = new StringBuilder();
ex.errors.fieldErrors.each { FieldError field ->
mensagem.append("O campo ").append( field.field )
.append(" da classe ")
.append( field.objectName )
.append(" com o valor ")
.append( field.rejectedValue )
.append(" não passou na validação.")
.append("\n")
}
flash.error = mensagem.toString()
return [usr: usuario]
}catch(ex) {
flash.error = ex.message
render "Erro"
//return [usr: usuario]
}
}else {
usuario.errors.allErrors.each { println it }
render "Erro"
//return [usr: usuario]
}
}
mockFor would give you back a mock control. You have to explicitly call createMock() on the mock control to get the actual mocked object.
service = mockFor(UsuarioService).createMock()
Have a look at "Mocking Collaborators" from the same link you referred. The test can be optimized if you still face an issue.
similar example and one here.
You need to set an expectation on the UsarioService to say what will be returned when usarioService.save(...) is called.
Before getting to that point, you need to say in the test
mockUsarioService.createMock() which will create the actual instance of the mock object, that's what you will pass to the controller usarioService attribute. Copied the code below from the Grails documenation. http://grails.org/doc/1.1/guide/9.%20Testing.html
String testId = "NH-12347686"
def otherControl = mockFor(OtherService)
otherControl.demand.newIdentifier(1..1) {-> return testId }
// Initialise the service and test the target method.
def testService = new MyService()
testService.otherService = otherControl.createMock()

I could use some advice in how to mock an auto wired dependency used in a Grails unit test. I've omitted most of the unnecessary code and just given the test class and the relevant methods in the file class under test
class UserService {
def springSecurityService // spring bean
def passwordEncoder // auto wired as per
//https://stackoverflow.com/questions/33303585/spring-//security-encode-password-with- bcrypt-algorithm
.....
def passwordPreviouslyUsed(String newPassword, def userId){
def passwordExists = false
def usersPasswords = findPasswordsForUser(userId)
usersPasswords.each{ password ->
if (passwordEncoder.isPasswordValid(oldPassword, newPassword, null)) {
passwordExists = true
}
}
return passwordExists
}
.....
def findPasswordsForUser(def userId){
User foundUser = User.findById(userId)
def passwordsForUser = UserPasswords.createCriteria().list {
eq('user', foundUser)
projections{
property('password')
}
}
passwordsForUser
}
My test
class UserServiceSpec extends Specification implements DataTest, ServiceUnitTest<UserService> {
def passwordEncoder
def setupSpec() {
mockDomains User, UserPasswords
}
def setup() {
def stubPasswordEncoder = Stub(passwordEncoder) {
isPasswordValid(_, _, _) >> true
}
service.passwordEncoder = stubPasswordEncoder
}
void "test for user passwordPreviouslyUsed"() {
given: "a user already exists"
setup()
service.createNewUser("testName", "testy#test.com", "Secret1234" )
//^(does some validation, then User.save())
User foundUser = User.findByEmail("testy#test.com")
foundUser.fullName == "testName"
long testUserId = foundUser.id
and: "we update the password for that user, and it to the userPasswords"
UserPasswords newUserPassword = new UserPasswords(
user: foundUser,
password: "newPassword1"
)
newUserPassword.save()
//use passwordPreviouslyUsed method to check a string with the same value as the
//previously
//updated password to check if it has already been used
when: "we check if the password has been used before"
def response = service.passwordPreviouslyUsed("newPassword1", fundsyId)
then:
response == true
}
Without stubbing or mocking this dependency, I get the error
Cannot invoke method isPasswordValid() on null object
I tried to stub password encoder and have it return true
def stubPasswordEncoder = Stub(passwordEncoder) {
isPasswordValid(_, _, _) >> true
}
service.passwordEncoder = stubPasswordEncoder
But this gives an error message:
Stub in 'spock.mock.MockingApi' cannot be applied to '(java.lang.Object, groovy.lang.Closure)'
Is there any way to mock this dependency with Spock?
Stub and Mock take a class - you're giving it an instance that is null - hence the exception.
You should be able to mock it as so:
def mockPasswordEncoder = Mock(PasswordEncoder)
// note this is the class
// org.springframework.security.crypto.password.PasswordEncoder
I tried enrichelgeson's approach, and it worked!
I first imported PasswordEncoder to the test class
import org.springframework.security.crypto.password.PasswordEncoder
then implemented the normal mocking procedure. I was initially confused because they class under test just implicitly created an instance of the class by defining it.
def stubPasswordEncoder = Stub(PasswordEncoder) {
isPasswordValid(_, _, _) >> true
}
service.passwordEncoder = stubPasswordEncoder
I also found another solution that didn't require mocking
service.passwordEncoder = [ isPasswordValid: { String rawPass, String salt, Null -> true } ]
Both approaches work fine. Thanks for the help!
Hi guys i am on trouble about getting the current user provided by spring.
Here's my unit test code
void "Test if adding project will sucess"() {
given:
def createProjectMock = mockFor(UserService)
createProjectMock.demand.createNewProject { Map projectMap ->
return true
}
controller.userService = createProjectMock.createMock()
when: "saveProject is execute"
controller.saveProject()
then: "page will to the list to view the saved project"
response.redirectedUrl == '/user/index2'
}
Here's my controller
def saveProject(ProjectActionCommand projectCmd) {
def currentUser = springSecurityService.currentUser
if (projectCmd.hasErrors()) {
render view: 'createProject', model: [projectInstance: projectCmd, user:currentUser]
} else {
def getProjectMap = [:]
getProjectMap = [
projectName: params.projectName,
user: currentUser
]
def saveProject = userService.createNewProject(getProjectMap)
if (saveProject) {
redirect view: 'index2'
} else {
render 'Error upon saving'
}
}
}
And here's my service
Project createNewProject(Map projectMap){
def createProject = new Project()
createProject.with {
projectName = projectMap.projectName
user = projectMap.user
}
createProject.save(failOnError:true, flush: true)
}
And i always getting this error:
Cannot get property 'currentUser' on null object.
Hope you can help me. Thanks
Cannot get property 'currentUser' on null object.
means that you haven't mocked springSecurityService. Let's do it in setup section (I assume it may be useful also in other methods in this class):
def springSecurityService
def setup() {
springSecurityService = Mock(SpringSecurityService)
controller.springSecurityService = springSecurityService
}
At this point your code is going to work. However remember that you can always mock also the actual logged user and test it at any point:
User user = Mock(User)
springSecurityService.currentUser >> user
I am unit testing a Grails controller method that internally creates an user instance. User domain class uses the springSecurityService of the Spring Security plugin to encode the password before inserting it into the database.
Is there a way to mock that springSecurityService from my unit test in order to get rid of that error?
Failure: Create new individual member(MemberControllerSpec)
| java.lang.NullPointerException: Cannot invoke method encodePassword() on null object
Please find my unit test below.
#TestMixin(HibernateTestMixin)
#TestFor(MemberController)
#Domain([User, IndividualPerson])
class MemberControllerSpec extends Specification {
void "Create new individual member"() {
given:
UserDetailsService userDetailsService = Mock(UserDetailsService)
controller.userDetailsService = userDetailsService
def command = new IndividualPersonCommand()
command.username = 'scott#tiger.org'
command.password = 'What ever'
command.firstname = 'Scott'
command.lastname = 'Tiger'
command.dob = new Date()
command.email = command.username
command.phone = '89348'
command.street = 'A Street'
command.housenumber = '2'
command.postcode = '8888'
command.city = 'A City'
when:
request.method = 'POST'
controller.updateIndividualInstance(command)
then:
view == 'createInstance'
and:
1 * userDetailsService.loadUserByUsername(command.username) >> null
and:
IndividualPerson.count() == 1
and:
User.count() == 1
cleanup:
IndividualPerson.findAll()*.delete()
User.findAll()*.delete()
}
}
One way to mock a service is to use Groovy's MetaClass
import grails.test.mixin.Mock
import grails.plugin.springsecurity.SpringSecurityService
...
#Mock(SpringSecurityService)
class MemberControllerSpec extends Specification {
def setupSpec() {
SpringSecurityService.metaClass.encodePassword = { password -> password }
}
def cleanupSpec() {
SpringSecurityService.metaClass = null
}
....
In this example, the call to SpringSecurityService.encodePassword() will simply return the password in plain text.
An approach using Mocks is discussed here.
You can to use this code to encode password in User:
def beforeInsert() {
encodePassword()
}
def beforeUpdate() {
if (isDirty('password')) {
encodePassword()
}
}
protected void encodePassword() {
password = springSecurityService?.passwordEncoder ? springSecurityService.encodePassword(password) : password
}
When springSecurityService is null, encodePassword is not called and NPE is not raised
When you use controller unit test with spring security rest plugin in Grails v4/v3, if your controller method reference springSecurityService methods like 'athenticatedUser', there will be NullPointException, because springSecurityService is not autowired into the spring application context.
Add code like below, you can inject springSecurityService and mock it's methods.
class GuessControllerSpec extends Specification implements ControllerUnitTest<GuessController> {
#Override
Closure doWithSpring() {
return {
// mock method
SpringSecurityService.metaClass.getCurrentUser = {return new User()}
// inject into spring context
springSecurityService(SpringSecurityService)
}
}
...
}
I have the following lines of code
username = username.stripIndent()
user = User."${databaseInstance}".findByUsername(username)
if (user == null){
return "User does not exist"
}
I'm trying to unit test this functionality with:
def setup() {
def mockUser = Mock(User)
myClass.user = mockUser
}
void "userNotFoundGetUserInfo"(){
given:
myClass.databaseInstance = 'X'
_ * mockUser._ >> null
when:
def result = myClass.getUserInfo(username)
then:
result == "User does not exist"
}
but I keep getting an error of "No such property: X for class mypackage.User"
I realize this is because i'm mocking the "user" object and not the "User" class, so how do I get around the fact that my code is making a direct call to a domain class?
Use Grails built-in #Mock annotation instead of Spock's Mock() method. Go like:
#Mock(User)
class YourTestSpecification extends Specification {
def setup() {
myClass.user = new User()
}
}
#Mock is meant to mock Grails domain classes.
I'm writing controller unit tests and I'd like to test json result when creation fails.
How can I register VndErrorJsonRenderer in unit test ? I tried simply defineBeans in setup() but it doesn't work :(
import com.vividsolutions.jts.geom.Coordinate
import grails.transaction.Transactional
import org.codehaus.groovy.grails.web.servlet.mvc.GrailsParameterMap
import static org.springframework.http.HttpStatus.CREATED
import static org.springframework.http.HttpStatus.NO_CONTENT
#Transactional(readOnly = true)
class UserController {
static namespace = "v1"
static allowedMethods = [profile: 'GET', create: "POST", update: "PUT", delete: "DELETE"]
static responseFormats = ['json', 'vnd.error+json']
def springSecurityService
def geometryFactory
/**
* Saves a resource
*/
#Transactional
def create() {
User instance = createResource(params)
instance.validate()
if (instance.hasErrors()) {
respond instance.errors, view: 'create' // STATUS CODE 422
return
}
instance.save flush: true
respond instance, [status: CREATED]
}
protected User createResource(GrailsParameterMap params) {
Double x = params.double("location.x", 0)
Double y = params.double("location.y", 0)
User user = new User()
bindData(user, params, [include: ['username', 'password', 'profile.*']])
if (x > 0 && y > 0)
user.location = geometryFactory.createPoint(new Coordinate(x, y))
else
user.location = null
user.roles = []
user.roles.add(Role.findByAuthority(Role.ROLE_USER))
return user
}
}
And my test :
#Before
void setup() {
defineBeans {
vndJsonErrorRenderer(VndErrorJsonRenderer)
}
}
void "Test the create action with a non unique username"() {
User.metaClass.encodePassword = {
"aaa"
}
// Create first user
assertNotNull getValidUser().save(flush: true)
when: "The create action is executed with a username already used"
def user = getValidUser()
controller.request.addHeader("Accept", "application/vnd.error+json,application/json")
controller.request.contentType = "application/json"
controller.request.content = JsonMapperUtil.mapAsJson(user)?.getBytes()
controller.create()
then: "The response status is UNPROCESSABLE_ENTITY and the username unique error is returned"
println response.text
response.status == UNPROCESSABLE_ENTITY.value
def json = JSON.parse(response.text)
assertNull "VND format not returned", json.errors
}
I'm using grails 2.3.6 with restful controller.
Thanks
In the case you are showing where you depend on respond it would be best to test this more as an integration test so all components that may interact with respond are all wired for you.
In a unit test for what ever beans are needed in the class under test I find it easiest to directly set them on the class under test.
