PROBLEM:PROBLEM:
I am receiving a "Method is not visible: Boolean VerifyDate.DateWithin30Days(Date, Date)" on my 3rd, 4th, and 5th. I am also receiving a "Method is not visible: Date VerifyDate.SetEndOfMonthDate(Date)" on my 6th method. Does anyone have any ideas? Your help would be greatly appreciated. Thank you!
CHALLENGE:CHALLENGE:
Create a unit test for a simple Apex class.
Install
Install a simple Apex class, write unit tests that achieve 100% code coverage for the class, and run your Apex tests. The
The Apex class to test is called 'VerifyDate', and the code is available here. Copy and paste this class into your Developer Edition via the Developer Console. 'VerifyDate' is a class which tests if a date is within a proper range, and if not will return a date that occurs at the end of the month within the range. The unit tests must be in a separate test class called 'TestVerifyDate'. The unit tests must cover scenarios for all lines of code included in the Apex class, resulting in 100% code coverage. Run
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.
