PHPUnit in Laravel: Simple Example of Why/How to Test

Here, I'm showing WHY we need unit-testing and how beneficial it is, in order to avoid bugs. Together, we write tests for existing feature, then refactor that feature, find a bug, and make sure that tests are working again.

This is why you should always write your test before coding. Great work!

This is what I'm looking for, hoping to see more of these. Thanks, Laravel Daily for sharing your daily knowledge. Godbless.

I usually go with the repository pattern, injecting a repository interface into the service and at the Unit test I use a mock of that to get data from the "database". According to Uncle Bob a Unit Test should be able to work either you have a database or not having one. Also by randomly generating data you can not be sure in every test what the outcome will be. Maybe works in this case but if you wanted to check the total amount of a period it would not work unless you insert specific data to test. Anyway, I really like your videos, there are very helpful.

[JohnnyBigodes]

This was a good example... Loved it... Could you share the difference between Unit and Feature tests?? There is a lot of wrong asumptions out there.

[edpogi]

what css framework did you use for this lesson?

[raimonds.L]

I remember doing unit tests on sqlite and dev running on mysql

Hi Povilis. Do you know any "trick" to clone a database as you mention? I have a production database and I want to start testing with a clean database as you mention in the video! (I have no migrations as is a legacy project)

Hi, I have a lot of code in my controller/index, which builds me a json api from all kinds of joined tables. Is there a way to assert if all the json data is provided, that is required by the frontend, and return some error if any of these json items aren't accessible? It would be easier to test like that rather than always swap between the frontend and the backend for errors. Thank you.

How are tests are performing so fast ?
On my local it takes lots of time to load phpunit and then runs test
Please help
