Testing is a crucial a part of SDLC. So, earlier than deploying our code to the manufacturing atmosphere, Salesforce requires at the least 75% of your code to be coated by our check lessons which.

- As soon as your check code runs between Check.startTest() and Check.stopTest(), you have to use assert statements to check whether or not your precise code is executing accurately and giving the outcomes as anticipated. In our case, we’re testing whether or not the e book’s value has been set to 90 or not. If this assert assertion returns false, then your check class will fail, and can let , that one thing is just not right in your code, and it’s worthwhile to repair your authentic code.
