Ktor:使用JUnit Test Class的Spek / KotlinTest instad测试REST端点

我有一个简单的你好世界Ktor app:

fun Application.testMe() {
  intercept(ApplicationCallPipeline.Call) {
    if (call.request.uri == "/")
      call.respondText("Hello")
    }
}

使用JUnit测试类,我可以为它编写测试,如文档中所示;如下:

class ApplicationTest {
    @Test fun testRequest() = withTestApplication(Application::testMe) {
        with(handleRequest(HttpMethod.Get, "/")) {
            assertEquals(HttpStatusCode.OK, response.status())
            assertEquals("Hello", response.content)
        }
        with(handleRequest(HttpMethod.Get, "/index.html")) {
            assertFalse(requestHandled)
        }
    }
}

但是,我想在没有JUnit帮助的情况下在Spek或KotlinTest中进行单元测试,类似于我在ScalaTest / Play中的方式;以更具声明性的方式:

  1. 在测试期间向路线发送FakeRequest(即/)。
  2. 获取页面内容,并检查字符串" hello"。
  3. 问题是我可以在KotlinTest或Spek中以更具声明性的方式编写上述测试吗?

首先,请关注spek setup guide with JUnit 5

然后您可以简单地声明您的规范,如下所示

object HelloApplicationSpec: Spek({
    given("an application") {
        val engine = TestApplicationEngine(createTestEnvironment())
        engine.start(wait = false) // for now we can't eliminate it
        engine.application.main() // our main module function

        with(engine) {
            on("index") {
                it("should return Hello World") {
                    handleRequest(HttpMethod.Get, "/").let { call ->
                        assertEquals("Hello, World!", call.response.content)
                    }
                }
                it("should return 404 on POST") {
                    handleRequest(HttpMethod.Post, "/", {
                        body = "HTTP post body"
                    }).let { call ->
                        assertFalse(call.requestHandled)
                    }
                }
            }
        }
    }
})

这是我的build.gradle(简化)

buildscript {
    dependencies {
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.3'
    }

    repositories {
        jcenter()
    }
}

repositories {
    jcenter()
    maven { url "http://dl.bintray.com/jetbrains/spek" }
}

apply plugin: 'org.junit.platform.gradle.plugin'

junitPlatform {
    filters {
        engines {
            include 'spek'
        }
    }
}

dependencies {
    testCompile 'org.jetbrains.spek:spek-api:1.1.5'
    testRuntime 'org.jetbrains.spek:spek-junit-platform-engine:1.1.5'
    testCompile "io.ktor:ktor-server-test-host:$ktor_version"
}
