Is dusk is mandatory to write phpunit test cases?how to write phpunit test cases in laravel 5.4?

Question

I am newbie to laravel. I am using laravel 5.4 version, we have requirement of writing phpunit test cases for our application, So I have searched for writing phpunit testcases and also read the documentation in laravel website. I read about the 'dusk' feature for doing the browser tests. So, I have a doubt that is "Is the dusk is mandatory for writing the phpunit test cases in laravel 5.4? I also tried to install the 'dusk' package into our application but it is not getting installed after I run the command "composer require laravel/dusk".

below is the error that I am getting on command prompt:

c:\xampp\htdocs\ourappname>composer require laravel/dusk

Anyone please tell me how to fix it? and also what is the process for writing the test cases in laravel 5.4? should we use 'dusk'? or any other way to do it? Thanks.

No, Dusk is not required to do unit testing. You can just use the basic tests.

Your error is related to when you installed the Excel package on your application; the Service Provider was added to your config/app.php, but now that you've removed the package from your application ("Removing maatwebsite/excel (2.1.17)") you also need to remove the Service Provider.
