Hi I ve run an issue with testing a Ktor app where the test kotlinlang #ktor

is expected. Running the app and calling the same endpoint via curl works as expected, leading me to believe that I’ve done something wrong with the test client setup. Any pointers would be appreciated. Details in thread.

Test set up is as follows:

testApplication {
  // ... test application setup ...
  
  val testClient = createClient {
      install(ContentNegotiation) {
          json(Json { DefaultJson })
      }

      install(Auth) {
          bearer {
              loadTokens {
                  BearerTokens(jwt, "nope")
              }
          }
      }
  }

  <http://testClient.post|testClient.post>("/some-post-endpoint") {
      accept(ContentType.Application.Json)
      contentType(ContentType.Application.Json)
      setBody(CreationRequest("test", listOf("test"), "testOrg", "testId"))
  }.apply {
      assertEquals(HttpStatusCode.Created, status)
  }
}

ContentNegotiation

plugin config match the server.

Removing the

createClient

bit and doing the post manually

<http://client.post|client.post>("/some-post-endpoint") {
    accept(ContentType.Application.Json)
    contentType(ContentType.Application.Json)
    header(HttpHeaders.Authorization, "Bearer $jwt")
    setBody(
        """
        {
          ... some raw json ...
        }
    """.trimIndent()
    )
  }.apply {
    assertEquals(HttpStatusCode.Created, status)
  }

Still returns

415 Unsupported Media Type

. What am I missing here?

Aha, found it! Completely my fault. I had missed one of the extension methods with plugins when building

testApplication

🤦
