When I am trying to run the following test case
class QuestionsControllerUnitSpec extends PlaySpec with BeforeAndAfterAll with BeforeAndAfterEach with OneAppPerSuiteWithComponents{
{
...
"newQuestion" should {
"should return error if the size of the body in the request is more than the maximum allowed size" in {
val testEnv = new QuestionsControllerSpecTestEnv(components=components)
val body =
s"""
|{
| "practice-question":{
| "description": "some description",
| "hints": ["hint1","hint2"],
| "image": ["image1 data","image2 data","image3 data"],
| "success-test": "success test",
| "fail-test": "fail test",
| "tags": ["${testEnv.tag}","${testEnv.tag}"],
| "title":"some title",
| "answer": "some answer",
| "references":["ref1","ref2"]
| }
|}
""".stripMargin
val sizeConfig = Map("maxAllowedBodySize"-> 10)
val maxBodySizeConfig = Map("codingJedi" -> sizeConfig )
val newConfiguration = Configuration.from(maxBodySizeConfig)
val questionControllerTestEnv = new QuestionsControllerSpecTestEnv(Some(newConfiguration),components)
val jsonBody = Json.parse(body)
val request = new FakeRequest(FakeRequest("POST","ws/questions/new-question")).withAuthenticator(testEnv.testEnv.loginInfo)(testEnv.testEnv.fakeEnv).withBody(AnyContentAsJson(jsonBody))
val response = questionControllerTestEnv.questionsController.newQuestion(request)
val responseBody = contentAsJson(response)(Timeout(Duration(5000,"millis")),testEnv.testEnv.mat)
println(s"received response body ${responseBody}")
val result = (responseBody \ "result").get.as[String]
val additionalInfo = (responseBody \ "additional-info").get.as[String]
result mustBe "error"
additionalInfo mustBe components.messagesApi("error.entityTooLarge")(components.langs.availables(0))
}
}
...
}
I am getting error java.lang.UnsupportedOperationException: NoMaterializer does not provide an ExecutionContext. What does it mean and how can I solve it?
The test case is suppose to reject an incoming request with 413 response
If I don't pass the materializer to contentAsJson, I get error Error:(1480, 39) could not find implicit value for parameter mat: akka.stream.Materializer
val responseBody = contentAsJson(response)
