Karina Chang Test class for extension
Hi, I need to move the following extension to production - however, I am not sure how to write the test class for the code below (since there is a VisualForce using the Extension):
public class TrainingExtension {
private final Training_Courses__c tc;
public List<Training_Courses_Dates__c> Training_Dates {get;private set;}
public String TrainingCourseDateId {get; set;}
public String LocationDate {get; set;}
public TrainingExtension (ApexPages.StandardController stdController) {
this.tc= (Training_Courses__c)stdController.getRecord();
Training_Dates = [SELECT Status__c,Class_Name__c,Location__c, Start_Date__c, Start_Date_Formula__c, Location_and_Date__c from Training_Courses_Dates__c where Training_Course__c =: tc.id and Status__c != 'Completed' order by Start_Date__c asc LIMIT 100 ];
}
public void DisplayDate ()
{
TrainingCourseDateId = ApexPages.currentPage().getParameters().get('TCDID');
List <Training_Courses_Dates__c> crtCourseDates = [SELECT Location_and_Date__c from Training_Courses_Dates__c where ID = : TrainingCourseDateId];
LocationDate = crtCourseDates [0].Location_and_Date__c;
}
}
Thanks,
Karina

Please try below test class as sample
@isTest public class TrainingExtensionTest { static testMethod void testMethod1() { Training_Courses__c tc = new Training_Courses__c(); // Add all required field insert tc; Training_Courses_Dates__c tcd = new Training_Courses_Dates__c(); tcd.Training_Course__c = tc.id; tcd.Status__c ='Open'; // Add value according to your org insert tcd; Test.StartTest(); ApexPages.StandardController sc = new ApexPages.StandardController(tc); TrainingExtension ext = new TrainingExtension(sc); ext.DisplayDate(); Test.StopTest(); } }Please follow below salesforce Best Practice for Test Classes :-
1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .
