UPDATE

Looks like you are using the unmanaged package. So I think if you don’t want to uninstall before going to production your going to have to fix those errors manually by fixing the code.

Unfortunately, SFDC test methods don’t live in a complete vacuum where you can run tests against your org without bumping other code, even when you go to deploy.

Q476) How Can I Tell the Day of the Week of a Date?

Formulas

There isn’t a built-in function to do this for you, but you can figure it out by counting the days since a date you know. Here’s the concept: I know that June 29, 1985 was a Saturday. If I’m trying to figure out the day of the week of July 9 of that year, I subtract the dates to determine the number of days (10), and then use modular division to figure to remove all the multiples of 7. The remainder is the number of days after Saturday (1 = Sunday, 2 = Monday, etc.) and you can use that number in your logic:

MOD(DATEVALUE( Date_Field__c ) – DATE(1985,7,1),7)

Apex Code

You could do the same thing with time deltas, but you can also use the poorly

documentedDateTime.format() function:

// Cast the Date variable into a DateTime

DateTime myDateTime = (DateTime) myDate;

String dayOfWeek = myDateTime.format(‘E’);

// dayOfWeek is Sun, Mon, Tue, etc.

Q477) What is App in Salesforce?

An app is a group of tabs that work as a unit to provide functionality. Users can switch between apps using the Force.com app drop-down menu at the top-right corner of every page.

You can customize existing apps to match the way you work or build new apps by grouping standard and custom tabs.

Navigation to create an app in Salesforce: Setup ->Build ->Create->App-> Click on new and create your application according to your requirements.

Q478) What is the object in Salesforce.com?

Objects are database tables that allow you to store data specific to your organization in salesforce. You can use custom objects to extend salesforce.com functionality or to build new application functionality.
