需要 JSON 内容的远程 Web 服务的 Grails 2.2 功能测试

Question

我正在使用 Grails 2.2 并正在编写一个功能测试来验证从远程 Web 服务收到的 JSON 响应。 Web 服务需要在请求中传递一些 JSON 内容。

当我使用 "Postman" 之类的工具测试此 Web 服务时，我收到了正确的 JSON 响应。

我为此在 Grails 2.2 中编写了一个功能测试用例。下面提供了我的示例代码片段。

import com.grailsrocks.functionaltest.*
import com.grailsrocks.functionaltest.client.APIClient

class RemoteWebServiceFunctionalTests extends TestCaseBase{

    void testPost() {
        post("http://remoteAddress:8080/services/getData", {
            param1 = "value1"
            param2 = "value2"
            ...
            ...
            param3 = "value3"
        })

        assertStatus 200
    }

    @Override
    Class getDefaultClientType() {
        APIClient
    }
}

下面提供了运行测试用例的输出以供参考。

|Running 1 functional test... 1 of 1

== Making request POST http://remoteAddress:8080/services/getData parameters: ==
param1: value1
param2: value2
...
...
param3: value3

== Request headers: ============================================================

================================================================================
== Response was 200 (OK) headers: ==============================================
Server: Apache-Coyote/1.1
Content-Type: application/json

================================================================================
== Content =====================================================================
{"errors":[{"Error0001":"Invalid request. Please refer to API definition"}],"result":null,"warnings":null}
================================================================================

当我运行测试时，我确实得到了状态 200，但是没有收到正确的 JSON 响应内容。我想我没有正确格式化请求。我需要知道在功能测试用例中向远程 Web 服务调用提供 JSON 内容的正确方法。

Answer 1

我找到了在正文中提供 JSON 以发出 POST 请求的正确方法。

import com.grailsrocks.functionaltest.*
import com.grailsrocks.functionaltest.client.APIClient

class RemoteWebServiceFunctionalTests extends TestCaseBase{

    void testPost() {

        post("http://remoteAddress:8080/services/getData") {

            headers['Content-Type'] = 'application/json'

            body {
                """
                {"param1":"value1","param2":"value2",...,"param3":"value3"}
                """
            }
        }

        assertStatus 200

        // assuming that the POST method is sending a response with the original request content,
        // similar to the sample web service available at "http://httpbin.org/post"
        assertContentContains "param1"

    }

    @Override
    Class getDefaultClientType() {
        APIClient
    }
}
