    Default how to make sure backend code is working when it doesn't have UI

    Hi,

    I am new to jave and I have one qoestion. I am asked to code DAO layer only,

    I can write the code like in DAO layer we write to post some field to the database. I can write the method but I dont know if it really works or not.

    As I dont know how to trigger the method in the first place as it doesn''t have a UI.

    How do we trigger to run a DAO method only when there are no other flow which triggers this method to run.

    In short how to test or debug if this and only this method is working. I need this immediately for my work so please reply as soon as possible.

    Thank you.

    Hi,
    you can setup a JUnit test, or you simply instanciate your DAO class and invoce the method from a small driver class.

    Creating a JUnit test would be the best way to approach this if your backend code is complex, since unit testing will allow you to easily test each individual scenario in one go. If you need any help on how to set up a unit test, feel free to ask and I can walk you through it.
