Salesforce Apex:测试未进行标注 [英] Salesforce Apex: test that callout hasn't been made

问题描述

我想编写一个单元测试来检查是否没有从触发器发出标注.

我知道如何通过实现 HttpCalloutMock 来测试标注是否正确:

I want to write a unit test that checks that callout hasn't been made from the trigger.

I know how to test if the callout is made correctly - by implementing HttpCalloutMock:

global class MyHttpCalloutMock implements HttpCalloutMock {
    global HTTPResponse respond(HTTPRequest req) {
        //test HTTPRequest here
    }
}

但是如果没有发出 HTTP 请求，那么 response() 方法将不会被调用.因此，这种方法根本不会测试是否发出了请求.

我需要这样的东西:

But if no HTTP request is made, then the respond() method won't be called. So this approach doesn't test if the request was made at all.

I need something like this:

HTTPRequest.assertNoRequestsHaveBeenMade();

我该怎么做?

推荐答案

所以我想通了.结果证明 Salesforce 有方法 Test.startTest() 和 Test.stopTest() 使异步标注同步:https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_tools_start_stop_test.htm

So I figured it out. It turns out that Salesforce has methods Test.startTest() and Test.stopTest() that make asynchronous callouts synchronous: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_tools_start_stop_test.htm

使标注同步后，测试它们就容易多了.

After making callouts synchronous it's much easier to test them.
