模拟 Webservice 调用实现

Question

Salesforce 中的最近工作测试 classes 由于此错误而开始失败

定义为 TestMethod 的方法不支持 Web 服务标注堆栈跟踪：null

我已经查看了顺丰的回复https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_callouts_wsdl2apex_testing.htm

但不明白在测试中在哪里实现调用class。

我创建了一个 Mock Webserivce class 但不知道在哪里调用 mock class。

这是失败的测试 class：

@isTest
public class OppLineItemInventoryTriggerTest {
    static testmethod void testdemo() {
        Account act = new Account(lastName = 'Testing', Billingstreet = '1234 Main', billing_as_shipping__c = True, Business_Unit__c = 'Vaya');
        insert act;
        Product2 prod = TestUtils.createProduct('product1');
        Id RecordTypeIdopp = Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('Package Lot').getRecordTypeId();
        Opportunity opp = new Opportunity();
        opp.AccountId = act.ID;
        opp.Name = 'Test';
        opp.Status__c = 'Completed';
        opp.Transfer_Type__c = 'Delivery';
        opp.StageName = 'New';
        opp.recordtypeid = RecordTypeIdopp;
        opp.CloseDate = Date.newInstance(2016, 12, 9);
        insert opp;
        Dosage__c dos = new Dosage__c();
        dos.Product__c = prod.ID;
        dos.Unit__c = 'mg';
        dos.Value__c = 5;
        insert dos;
        Product_Lot__c prolo = new Product_Lot__c();
        insert prolo;
        String standardPricebookId = Test.getStandardPricebookId();
        PricebookEntry pdb = new PricebookEntry(Pricebook2Id = standardPricebookId, Product2Id = prod.Id, IsActive = true, UnitPrice = 100);
        insert pdb;
        Opportunity opps = [Select id from Opportunity Limit 1];
        Contact con = new Contact(LastName = 'TestName');
        insert con;
        OpportunityLineItem oli = new OpportunityLineItem(OpportunityId = opps.Id, PricebookEntryId = pdb.Id, Quantity = 10, Shipping_Datetime__c = NULL, TotalPrice = 3000);
        insert oli;
        Inventory__c inv = new Inventory__c();
        inv.Product_ID__c = prod.ID;
        inv.Status__c = 'Completed';
        inv.Opportunity__c = opp.ID;
        inv.Days__c = '30';
        inv.Prescription__c = 'www.google.com';
        inv.Prescription_Line_Item_Id__c = 'test';
        inv.Product_Lot__c = prolo.ID;
        inv.Purchase_Date__c = Date.newInstance(2016, 12, 9);
        insert inv;
        sObject[] sObjectOldList = new sObject[] {};
        sObject[] sObjectNewList = new sObject[] {};
        sObject s11,s12;
        //sObjectOldList.add(oli);
        //sObjectNewList.add(oli);
        OppLineItemInventoryTrigger s1 = new OppLineItemInventoryTrigger(sObjectOldList, sObjectNewList);
        //  s1.execute(sObjectOldList, true);
        s1.execute(sObjectNewList, true);
        s1.executable(s11, s12);
    }

我创建了这个模拟网络服务class

global class YourHttpCalloutMockImpl implements HttpCalloutMock {
    global HTTPResponse respond(HTTPRequest req) {
        HttpResponse res = new HTTPResponse();
        res.setHeader('Content-Type', 'application/JSON');
        res.setBody('Your body');
        res.setStatusCode(201);
        return res;
    }
}

但不确定如何在测试中调用它class。

Answer 1

您不需要在单元测试中显式调用模拟 class。相反，您可以使用 Test.setMock() 调用来配置它，例如

Test.setMock(WebServiceMock.class, new YourHttpCalloutMockImpl ());

对于 SOAP 网络服务，或

Test.setMock(HttpCalloutMock.class, new YourHttpCalloutMockImpl ());

确保在调用要测试的代码之前执行此调用，这会发出标注。系统将自动使用您的模拟 class 响应出站 Web 服务调用 - 无需您进一步干预。

现在，您似乎正在查看 SOAP 文档，但已经编写了一个 HTTPCalloutMock - 确保您采用的模拟接口与您的代码进行的调用类型相匹配。

Answer 2

定义为 TestMethod 的方法不支持 Web 服务标注堆栈跟踪：null

出现此错误是因为测试 class 中不允许 Web 服务标注。

要绕过标注，请添加 HttpcalloutMock class。

这是一个示例测试 class，使用模拟 class 来绕过 Web 服务标注。

************************ 测试 Class ****************** **********

@isTest 
private class Test_class {

    private class RestMock implements HttpCalloutMock {

        public HTTPResponse respond(HTTPRequest req) {
            String fullJson = 'your Json Response';

            HTTPResponse res = new HTTPResponse();
            res.setHeader('Content-Type', 'text/json');
            res.setBody(fullJson);
            res.setStatusCode(200);
            return res;
        }
    }
    static testMethod void service_call() {

        Test.setMock(HttpCalloutMock.class, new RestMock());
        Test.startTest();

        //your web service call code

        Test.StopTest();


    }
}

模拟 class 将处理 Web 服务标注。
