Salesforce Apex:测试尚未进行标注

问题描述

我想编写一个单元测试，以检查是否未从触发器进行标注.

我知道如何测试标注是否正确-通过实现HttpCalloutMock:

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，则不会调用response()方法.因此，这种方法根本无法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

所以我知道了.事实证明，Salesforce具有使异步标注同步的方法Test.startTest()和Test.stopTest(): 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，对其进行测试要容易得多.

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