这是我的第一个顶级课程，我真的不知道如何实现一个合适的测试类。我的目标是实现75％的测试覆盖率。
我根据评论进行了更新，但我只获得了70％的成绩。我没有其他想法如何改善这一点。
这是我做的：
Apex类：
public with sharing class AccountController {
@AuraEnabled
public static List<Account> findAll() {
User userDetails =[SELECT Id, Name, Email, Profile.Name, UserRole.Name FROM User
where Id=:userinfo.getUserId() ];
// Theme4t is theme that is used by mobille app for android or iphone
if(((userDetails.UserRole.Name).equals('yon')|| (userDetails.UserRole.Name).equals('bon')|| (userDetails.UserRole.Name).contains('non')
|| (userDetails.UserRole.Name).contains('go')) && UserInfo.getUiTheme() != 'Theme4t'){
return [SELECT id, name, AccountStatus__c, ShippingLatitude, ShippingLongitude, ShippingCity
FROM Account
WHERE ShippingLatitude != NULL AND ShippingLongitude != NULL
LIMIT:22000];
}else {
return [SELECT id, name, AccountStatus__c, ShippingLatitude, ShippingLongitude, ShippingCity
FROM Account
WHERE OwnerId =: UserInfo.getUserId() AND ShippingLatitude != NULL AND ShippingLongitude != NULL
LIMIT:5000];
}
}
Apex测试类：
@isTest
public class AccountControllerTest
{
static testMethod void testMethod1()
{
Account acc = new Account();
acc.Name='Test';
insert acc;
User userDetails =[SELECT Id, Name, Email, Profile.Name, UserRole.Name FROM User
where Id=:userinfo.getUserId() ];
List<Account> lstAcc = AccountController.findAll();
UserRole ur =new UserRole();
userDetails.UserRoleId=[select Id from UserRole where Name='yon'].Id;
System.runAs(userDetails){
List<Account> lstAcc1 = AccountController.findAll();
}
userDetails.UserRoleId=[select Id from UserRole where Name='bon'].Id;
System.runAs(userDetails){
List<Account> lstAcc2 = AccountController.findAll();
}
userDetails.UserRoleId=[select Id from UserRole where Name='non'].Id;
System.runAs(userDetails){
List<Account> lstAcc3 = AccountController.findAll();
}
userDetails.UserRoleId=[select Id from UserRole where Name='go'].Id;
System.runAs(userDetails){
List<Account> lstAcc4 = AccountController.findAll();
}
}
请填写下面的trailhead以了解Salesforce中的单元测试。 https://trailhead.salesforce.com/en/content/learn/modules/apex_testing/apex_testing_intro
而且，当您尝试在帐户插入后创建用户时，它将抛出混合DML错误。你需要使用system.runAs（）方法。请按照以下网址使用该方法。
让我知道，如果仍然，你需要任何帮助。
这是您的类和测试类的代码。请遵循http://blog.shivanathd.com/2013/11/Best-Practices-Test-Class-in-Salesforce.html的最佳实践这次我将为您提供代码以了解如何创建测试类，但下次请按照我分享的步骤和文档进行操作。
public with sharing class AccountController {
//using a test visible variable for setting the ui theme check.
@TestVisible static Boolean isTheme4t = UserInfo.getUiThemeDisplayed() == 'Theme4t';
@AuraEnabled

User userDetails =[SELECT Id, Name, Email, Profile.Name, UserRole.Name FROM User where Id=:userinfo.getUserId()];
// Theme4t is theme that is used by mobille app for android or iphone
if(((userDetails.UserRole.Name).equals('yon')|| (userDetails.UserRole.Name).equals('bon')|| (userDetails.UserRole.Name).contains('non') || (userDetails.UserRole.Name).contains('go')) && !isTheme4t){
return [SELECT id, name, AccountStatus__c, ShippingLatitude, ShippingLongitude, ShippingCity FROM Account WHERE ShippingLatitude != NULL AND ShippingLongitude != NULL LIMIT 22000];
}else {
return [SELECT id, name, AccountStatus__c, ShippingLatitude, ShippingLongitude, ShippingCity FROM Account WHERE OwnerId =: UserInfo.getUserId() AND ShippingLatitude != NULL AND ShippingLongitude != NULL LIMIT 5000];
}
}
}
