1.测试Apex触发器
在部署触发器之前，编写单元测试以执行触发触发器的操作并验证预期结果。
让我们测试一下我们在编写Apex触发器单元之前使用过的触发器。
如果帐户记录具有相关机会，AccountDelete触发器将阻止删除该记录。
trigger AccountDeletion on Account (before delete) {
// Prevent the deletion of accounts if they have related opportunities.
for (Account a : [SELECT Id FROM Account
WHERE Id IN (SELECT AccountId FROM Opportunity) AND
Id IN :Trigger.old]) {
Trigger.oldMap.get(a.Id).addError(
'Cannot delete account with related opportunities.');
}
}
测试代码：
@isTest
private class TestAccountDeletion {
@isTest static void TestDeleteAccountWithOneOpportunity() {
// Test data setup
// Create an account with an opportunity, and then try to delete it
Account acct &#
