我一直在尝试找出 Web 服务标注的测试类。我有四个不同的课程。API_Member它具有所有参数以及字段的所有信息和匹配。我有一API_Response堂课，我有一个AccountTriggerand AccountTriggerHandler。

在 中AccountTriggerHandler，整个 HTTPRequest 和标注在我调用API_Member类的地方处理，然后从AccountTrigger.

现在困难在于测试类，因为我不是经验丰富的开发人员。

我将如何设法处理此代码的测试类（我已经进行了更改以防它是一些重要信息）？

public with sharing class AccountTriggerHandler {

    public void isAfterInsert(list<Account> accountNew) {
        for(Account a: accountNew) {
            sendData(a.Id);
        }
    }

    public void isAfterUpdate(list<Account> accountNew) {

    }

    @future(callout=true)
    public static void sendData(string accountId) {
        API_Member api = new API_Member(accountId);
        api.setupData();
        API_Member.Data data = api.dataList;
        string json = JSON.serialize(data); 
        system.debug('JSON' + json);
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        string url = 'http://api.XXXXXXXXXXXXXXXXXXXXXXX';
        string username = 'Ext-XXXXXXXXXXXXXXX-XXXXXXXXXXXXXX';
        string password = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
        Blob headerValue = Blob.valueOf(username + ':' + password);
        String authorizationHeader = 'Basic ' + EncodingUtil.base64Encode(headerValue);
        request.setHeader('Authorization', authorizationHeader); 
        request.setHeader('Content-Type', 'application/json;charset=UTF-8');
        request.setEndpoint(url);
        request.setMethod('POST');
        request.setBody(json);
        HttpResponse response = http.send(request);
        if (response.getStatusCode() == 201 || response.getStatusCode() == 200 ) {
            API_Response responseCTRL = (API_Response) System.JSON.deserialize(response.getBody(), API_Response.class);
            list<API_Response.Meta> m = responseCTRL.Meta;
            System.debug('recordID='+m[0].recordID);
            api.setResponse(m[0].recordID,response.getStatus());
        }
    }
}

这是 API_Member 类

public class API_Member {
    public Data dataList;
    public Account input;
    public Contact c;
    public class Data {

    public class Info {

                            WHERE AccountId =: input.Id
                            ORDER BY CreatedDate
                            ASC
                            LIMIT 1
        ];
        if(c.size() > 0){
            return c[0];
        }
        return null;
    }

    public Account getAccount(string accountId){
        Account a = [SELECT Id,
                    Ort__c,

这是 API_Response 类

对于单元测试，您将不得不模拟（伪造）您正在调用的服务。我们不能从单元测试中调用真正的服务，因为：

  • 部署成功/失败不应取决于某些 3rd 方服务器是否已关闭
  • 您不想在没有办法回滚的情况下将“我的真棒测试数据！！！111”消息发送到生产服务器。

您需要编写一段代码来假装它是该服务。这取决于你它会有多棒。它总是可以返回相同的消息。或者它可以检查它收到的数据，如果缺少必填字段则抛出错误。真的 - 你决定，你最清楚你应该测试多少个场景（你如何处理返回的错误？）

检查https://trailhead.salesforce.com/en/content/learn/modules/apex_integration_services/apex_integration_soap_callouts

模拟的整个概念也可以用于“正常”顶点，而不仅仅是标注。虽然可能有点高级主题：https ://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_stub_api.htm

编辑：

您需要 2 个可以标记为的类@isTest（因此它们不计入您的正常代码最大值）。这是 REST API，对吧？不是肥皂？也许https://trailhead.salesforce.com/content/learn/modules/apex_integration_services/apex_integration_rest_callouts会更好。在紧要关头，您可以将其设为 1 类，但它有点乱，将它们分开吗？

首先制作API_ResponseMock. 没必要global，public应该够了。就像是

@isTest
public class API_ResponseMock implements HttpCalloutMock {
    public HTTPResponse respond(HTTPRequest request) {
        // Create a fake response
        HttpResponse response = new HttpResponse();
        response.setHeader('Content-Type', 'application/json');
        response.setBody('if you have sample JSON document that the service would return - paste it here. You must have something you used as the JSON2Apex input?');
        response.setStatusCode(200);
        return response;
    }

这是基础，您可能不希望它在每个“标注”上都返回相同的内容，但已经足够好了。

并且AccountTriggerHandlerTest将是“正常”单元测试，创建测试帐户。就像是

@isTest
static void testCallout() {
    // Set mock callout class 
    Test.setMock(HttpCalloutMock.class, new API_ResponseMock());
    Test.startTest();
    insert new Account(Name = 'unit test'); // put whatever required fields you have
    Test.stopTest(); // @future's don't run until this line.

    // hm, what now? You have anything to "assert"? Will this callout be updating account maybe? Setting a Task with status=Completed, anything you can check?
}
