APEX test user creation
Taken from the documentation:
Generally, all Apex code runs in system mode, where the permissions and record sharing of the current user are not taken into account. The system method
runAs
enables you to write test methods that change the user context to an existing user or a new user so that the user’s record sharing is enforced. TherunAs
method doesn’t enforce user permissions or field-level permissions, only record sharing.You can use
runAs
only in test methods. The original system context is started again after allrunAs
test methods complete.The
runAs
method ignores user license limits. You can create new users withrunAs
even if your organization has no additional user licenses.@isTest private class TestRunAs { public static testMethod void testRunAs() { // Setup test data // This code runs as the system user Profile p = [SELECT Id FROM Profile WHERE Name='Standard User']; User u = new User(Alias = 'standt', Email='[email protected]', EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US', LocaleSidKey='en_US', ProfileId = p.Id, TimeZoneSidKey='America/Los_Angeles', UserName='[email protected]'); System.runAs(u) { // The following code runs as user 'u' System.debug('Current User: ' + UserInfo.getUserName()); System.debug('Current Profile: ' + UserInfo.getProfileId()); } } }
Building on this answer, I construct my test classes @TestSetup
methods such that I can create an arbitrary number of unique users using a shortened 8-char GUID to init the names and emails, like so:
@IsTest
public with sharing class NotificationTests {
@TestSetup
private static void setup() {
// Setup 4 Test Users
Profile p = [SELECT Id FROM Profile WHERE Name='Standard User'];
List<User> uu = new List<User>();
while (uu.size() < 5) {
Blob b = Crypto.GenerateAESKey(128);
String h = EncodingUtil.ConvertTohex(b);
String uid = h.SubString(0,8);
User u = new User(Alias = uid, Email= uid + '@myorg.com',
EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US',
LocaleSidKey='en_US', ProfileId = p.Id,
TimeZoneSidKey='America/New_York', UserName= uid + '@myorg.com');
uu.add(u);
}
insert(uu);
}
@IsTest
public static void myTest() {
/* ... */
}
}
