Test class: Assertion Failed

Question

I m trying to cover and test my apex code so I developped a test class to test my insertion, my the test is failed unfortulately; and gave me this error: Assertion error

here is my test class:

@isTest
private class TestTimeOff {

    static testMethod void myTimeOffTest() {
        Test.startTest();
         Time_Off__c to = new Time_Off__c();
            to.Start_date__c = Date.newInstance(12, 05, 2015);
            to.End_date__c = Date.newInstance(13, 05, 2015);
            //to.My_back_up__c = 'XXXX';
            to.Pattern__c = 'Payed time off';
            to.Comment__c='My Class Test';
      try{
             insert to;
        }
        catch(System.DMLException e){

        System.assert(e.getMessage().contains('Insertion failed'));
       }
       test.stopTest();
 }

}

an other problem; My_back_up__c is a reference to a user, how can I do this? should I give the user ID??

p.s. I have trigger launched before and after adding a Time Off

Thank you

You can use this for create a test user, in your test method.

    User u = new User(
                   FirstName = 'test',
                   LastName = 'test',
                   UserName = '[email protected]',
                   Email = '[email protected]',
                   ProfileId = UserInfo.getProfileId(),
                   Alias = 'TEST',
                   CommunityNickname = 'test.test',
                   EmailEncodingKey = 'ISO-8859-1',
                   LocaleSidKey = 'es_ES',
                   LanguageLocaleKey = 'en_US',
                   TimeZoneSidKey = 'Europe/Paris',
                   IsActive = true
                );
   insert u;

Can you tell us what is doing your trigger? i dont understand your assertion.

for My_back_up__c look up field you can directly query over the User Object without use of SeeAllData = true

You can follow the link:

https://stackoverflow.com/questions/11643324/how-can-i-create-an-user-with-system-administrator-profile-when-seealldata-fal

For Date Type Field in test cases, you can simply use

to_start_date__c = date.today();

to_ End_date__c= date.today().addDays(1);

This Post help me figure this out.

Triggering a DML Exception for Test Coverage You need to Modify your code slightly.

This finally worked for me. c is an invalid Contact that should be allowed in by trigger. The trigger throws a DML exception when it detects the invalid state.

    Test.startTest();
    try{
        if(Test.isRunningTest()){
            insert c;
        }
    }
    catch(System.DmlException e){    
    }
    Test.stopTest();

If you want to use some already existing records for an object in test case then you need to use SeeAllData = True like as

@isTest(SeeAllData=true)

Using this you don't need to insert record in test cases ,what you need to do is simply query the records from the database like:

objectName ob = [select id, name ,... from objectName where predicates.. Limit 1];

But this should be avoided as if we deploy the code to any production then it will query for the record and if it not exist then test case will fail and ultimately your deployment will not succeeded.
