I have the following functions in a controller
def render201 = {
render(status:201)
}
def render202 = {
response.setStatus(202)
}
def render203 = {
response.setStatus(203)
render(status:203)
}
def render204 = {
response.setStatus(204)
render(status:205)
}
And I have the following tests
void test201() {
controller.render201()
assertEquals(201, controller.response.status)
}
void test202() {
controller.render202()
assertEquals(202, controller.response.status)
}
void test203() {
controller.render203()
assertEquals(203, controller.response.status)
}
void test204() {
controller.render204()
assertEquals(204, controller.response.status)
}
test201 fails with this message
junit.framework.AssertionFailedError: expected:<201> but was:<200>
For some reason, if you don't explicitly set the response status, render will always return 200 when being run from a unit test.
Additionally, if I were to actually call these from a browser, render202 would return an error, but render201 and render203 would work just fine. I don't know what render204 would do.
What's going on here? Is this a bug in Grails?
Try something like this :
assertEquals(201, controller.renderArgs.status)
It worked for me.
If you want to understand the inside of mockController, look at :
https://svn.codehaus.org/grails/trunk/grails/src/groovy/grails/test/MockUtils.groovy
clazz.metaClass.getForwardArgs = {-> fwdArgs}
clazz.metaClass.getRedirectArgs ={-> redArgs}
clazz.metaClass.getRenderArgs ={-> renArgs}
clazz.metaClass.forward = {Map map -> forwardArgs.putAll(map)}
clazz.metaClass.redirect = {Map map -> redirectArgs.putAll(map)}
clazz.metaClass.render = {String text -> delegate.response.writer << text}
clazz.metaClass.render = {Converter arg -> delegate.response.writer << arg.toString()}
expected:<201> but was:<200> means you try to request operation which is returning some response. If you want to test 201 need to void method.

I have a piece of code that goes something like this:
somePublisher
.subscribeOn(...)
.flatMap { x -> someFunctionThatReturnsMono(x) }
.retry(3)
.subscribe()
So far I have managed to unit test happy paths, like whether the code inside map {...} is getting called, using the tools from reactor-test.
Now I want to test errors and retries. How can I test to make sure someFunctionThatReturnsMono(x) is getting called at most 4 times when consecutive errors occur?
Simple way is to mock function and count its calls:
def 'Test retry'(){
setup:
someBean = Mock(SomeBean)
def testMono = Mono.just(X)
.flatMap { x -> someBean.someFunctionThatReturnsMono(x) }
.retry(3)
.subscribeOn(Schedulers.elastic())
when:
StepVerifier.create(testMono).verifyError(IllegalArgumentException)
then:
4 * someBean.someFunctionThatReturnsMono(_ as X) >> Mono.error(new IllegalArgumentException())
}
Another one is to mock funtion to return PublisherProbe and count probe subscriptions:
def 'Test retry'() {
when:
PublisherProbe probe = PublisherProbe.of(Mono.error(new IllegalArgumentException()))
someBean = Mock(SomeBean) {
someFunctionThatReturnsMono(_) >> probe
}
def testMono = Mono.just(X)
.flatMap { x -> someBean.someFunctionThatReturnsMono(x) }
.retry(3)
.subscribeOn(Schedulers.elastic())
then:
StepVerifier.create(testMono).verifyError(IllegalArgumentException)
probe.subscribeCount() == 4
}
This is how I do it for one of my use-cases:
def "should retry failed action given number of times"() {
given:
def invocationCounter = new AtomicInteger(0)
when:
Mono<Void> mono = myService.doSth()
.doOnError { invocationCounter.incrementAndGet() }
then:
StepVerifier.create(mono)
.verifyErrorMatches { it == expectedError }
and:
invocationCounter.get() == 1 + retryNum
}
I have some static method:
class WebUtils {
static httpPostRequest(String url, Map data, Map headers) {
//some code here
}
}
And service:
class ChatService {
void sendMessage(String text) {
//some preparing code
WebUtils.httpPostRequest(url, data, headers)
}
}
Now I want to check invocation of static method in the service by unit-test. Somehow like this:
void "test sending message"() {
given:
String text = 'Test'
def mockedWebUtils = Mock(WebUtils)
when:
service.sendMessage(message)
then:
1*mockedWebUtils.httpPostRequest(_, [text: message], _)
}
But code above is not working. Is there legal way?
Try something like:
void "test sending message"() {
given:
WebUtils.metaClass.static.httpPostRequest = { String url, Map data, Map headers ->
return 'done' // you can do what you want here, just returning a string as example
}
when:
service.sendMessage( 'Test' )
then:
1
// test for something your method has done
}
The correct way is using GroovyMock instead Mock:
void "test sending message"() {
given:
String text = 'Test'
GroovyMock(global:true, WebUtils)
when:
service.sendMessage(text)
then:
1*WebUtils.httpPostRequest(_, [text: text], _)
}
I've found here:http://spockframework.org/spock/docs/1.3-RC1/interaction_based_testing.html#_mocking_static_methods
Given the following setup:
class MockingFilters {
def filters = {
all(controller:"simple", action:"list") {
before = {
log.info "This needs asserting"
return false
}
}
}
}
Is there a way to assert that the log.info has fired? I am unsure how to get a handle on the Filter, and thus be able to interaction test the log object.
void "test list action is filtered"() {
when:
withFilters(action:"list") {
// Important bit
// Not sure how to get a handle to the filter
1 * log.info("This needs asserting")
controller.list()
}
then:
// Whatever here
}
There are also other objects on the Filter that I would like to test, but this example should be reflective of those too.
In the below class, I just need RevShareFormula.withCriteria to return a result,
but getting the exception in resultTransformer() method.
Can anyone tell me how to Mock the below method so that i get some result from withCriteria
Here is the class:
class PartnerFinancialService {
def getPartnerPayeeRevenuShareDetails(long partnerPayeeId, def contextTypeCode) {
def partnerPayeesRevShareFormula = RevShareFormula.withCriteria {
resultTransformer(CriteriaSpecification.ALIAS_TO_ENTITY_MAP)
createAlias('partnerRevShareConfig', 'partnerRevShareConfig')
createAlias('pricingModel', 'pricingModel')
createAlias('partnerRevShareConfig.revshareCategory', 'revshareCategory')
and {
eq("revshareCategory.payeeProfileId", partnerPayeeId)
eq("revshareCategory.referenceContextTypeCode", contextTypeCode)
isNull("partnerRevShareConfig.revshareValidToDate")
}
projections {
property("id", "formulaId")
property("pricingModel.id", "pricingModelId")
property("pricingModel.pricingName", "pricingName")
property("pricingModel.pricingType", "pricingType")
..
..
}
}
}
Here is the test class
#TestFor(PartnerFinancialService)
#Mock(RevShareFormula)
class PartnerFinancialServiceSpec extends Specification {
void "test getPartnerPayeeRevShareDetails"() {
def partnerPayeeRevShare = new PartnerRevShareConfig()
partnerPayeeRevShare.id = 1
def revShareModel = new PricingModel();
revShareModel.id = 1
def partnerPayeeRevShareFormula = new RevShareFormula();
partnerPayeeRevShareFormula.id=5
partnerPayeeRevShareFormula.pricingModel = revShareModel
partnerPayeeRevShareFormula.partnerRevShareConfig = partnerPayeeRevShare
partnerPayeeRevShareFormula.revshareFormula = "revshare*10"
partnerPayeeRevShareFormula.revshareTierHighValue = 0
partnerPayeeRevShareFormula.revshareTierLowValue= 0
RevShareFormula.metaClass.static.withCriteria = {partnerPayeeRevShareFormula}
when:
def result = service.getPartnerPayeeRevenuShareDetails(1,"PKG")
then:
//assert result.pricingModel.id == 1
println "Succesfully Fetched from DB"
}
}
Getting the following exception.

Use an integration test. Never test ORM code with unit tests. I know it's slower and the experience is less enjoyable, but you are fooling yourself if you think that you are actually testing something related to database queries with this test. You are testing the testing framework of grails (the in-memory GORM implementation)
I am using shiro security in my grail application.
Grails version : 2.2.1
shiro : 1.2.0
I have a problem in writing grails unit test case for the controller with filter enabled. When the test case run without filters then it is working fine, if it runs withFilters then it is failing for accessControl() method not found in the controller. I dont know how to make Shiro's api to be visible while running the test case.I referred shiro unit test case link http://shiro.apache.org/testing.html but I couldn't get any info regarding accessControl().I have given sample code how my classes and test case looks like
MyController.groovy
def create() {
// getting request parameters and validation
String emailId = params.emailId
def ret = myService.createUser(emailId)
return ret
}
MyControllerFilters.groovy
def filters = {
loginCheck(controller: 'user') {
before = {
//do some business checks
// Access control by convention.
accessControl() // This is a dynamic method injected by ShiroGrailsPlugin to FilterConfig, but this is not visible during the test case.
}
}
MyControllerTests.groovy
#TestFor(MyController)
#Mock(MyControllerFilters)
class MyControllerTests {
#Before
void setup() {
// initializing some variables
}
void testCreateUserWithFilter() {
request.accessAllowed = true
withFilters(action:"create") {
controller.create()
}
assert response.message == "success"
}
}
Try to use:
ControllerOrService.metaClass.method = {
return "" //what you need to be returned
}
Add parameters to closure if method take parameters:
ControllerOrService.metaClass.method = { def a, def b ->
return a + b
}
Don't forget to use full name of method when you mock them in that way.
