Goal: Get to know the basics about the standard test helper libraries provided by Microsoft.
Supporting their standard tests, Microsoft has created a nice and very useful collection of helper functions in more than 70 library codeunits. These helper functions range from random data generations and master data generation to standard generic and more specific check routines.
Need a new item? You might make use of the CreateItem or CreateItemWithoutVAT helper functions in Library - Inventory (codeunit 132201).
Need a random text? Use the RandText helper function in Library – Random (codeunit 130440).
Want to get the same formatted error messages when verifying your test outcome? Use one of the helper functions in the Assert (codeunit 130000), such as IsTrue, AreNotEqual, and ExpectedError.
A frequently reappearing question during my workshops is:
