This channel is offering quality material worth your time. Thank you Gio. The only drawback since the content is mostly training related all topics are rushed through and hard to follow along especially when learning something new. The speach is way to fast and it help to playback slower in order to follow. Jumping between different screens quickly is also adding to the problem. But otherwise good material.

Hi Gio, I'm trying to learn PHP from your guide and so far it's going great, thank you! I tried to include a stylesheet and it doesn't seem to work though. I found that some people fixed it by adding "include /etc/nginx/mime.types;" into the nginx.conf location part, but that doesn't solve it for me. Any idea how this could be fixed? Thank you again!

[@ProgramWithGio]

Hey, how are you including the stylesheets? DM me on Twitter with screenshot & I'll help you troubleshoot it

[@g7k993]

What software do you suggest to improve my typing speed? Thank you for the video

[@ProgramWithGio]

[@dietrichmccray795]

Thank you for making this video!! I'm currently trying to do this and whenever I "extends TestCase", it gives me this error "Undefined type 'PHPUnit\Framework\TestCase'.". Are you able to tell me what it is wrong?

[@ProgramWithGio]

Have you set up autoloading properly in composer.json? DM me on Twitter and send me a screenshot of your composer.json and the test class and I can take a look.

[@keemkorn]

For anyone that may face a hurdle with class dependencies not being picked up properly when you run phpunit, make sure you include the autoload object within your composer, which Gio talked about in this video: kzbin.info/www/bejne/qKLdipd-md6AfpI. I had skipped that video and jumped straight into this one, and couldn't figure out why my classes weren't able to be found when running tests.

[@Armando-px8hi]

Gio I have some problems bro, so after downloading the phpunit in the vendor folder it creates only sebastian folder and nothing else. What can be the problem?

[@Armando-px8hi]

I just solved it GIO, in xampp I had the extension=zip in comments after uncommenting it, it helped. Thanks!

[@ProgramWithGio]

Awesome, glad you got it working, good job

[@nuvia1484]

Hello! I have a question. Our code is a mix of procedural and functional. Still, I want to have unit testing for my code. Is it possible to use PHPUnit for testing the functions? All of the examples given in the videos I watched are used for OOP and I don't know if I have to change something for PHPUnit to work.

[@ProgramWithGio]

Hello! You could use PHPUnit to test procedural code. You may need some additional setup within the setup method but it's doable. Depending on what the function is or how complex it is, it might not be that hard to actually write tests for it. You could use include/requires if you are not using namespaces but I would recommend starting converting to OOP when possible.

[@nuvia1484]

@@ProgramWithGio Thanks Gio! I really like to explore and practice OOP but we don't have much time to implement OOP and MVC to our project since we have little knowledge about it. Thanks again!

[@ProgramWithGio]

@@nuvia1484 Makes sense. You're welcome

[@vuejs1]

why do we use parent::setUp(); in the setUp function? what the point? I thought we use it if our class extends other parent custom class?

[@ProgramWithGio]

In this specific example yes there is no need because its empty in the parent class. The parent::setUp() call was generated by IDE automatically when I overrode the method. That being said, it does not hurt to call the parent when overriding methods unless you specifically dont want to call it because in some cases it may contain crucial setup procedures needed for testing.

[@jordanbicanic9343]

I noticed that you run compose to install phpunit directly in docker image. Is that necessary? I have composer installed globally

[@ProgramWithGio]

Depends on your setup, in some cases you may not need it but I prefer to have it available in container

[@pat1938]

Hey Gio, I've got a weird problem. After installing phpunit with composer and building the app I do get the PHPUnit folder with the files within the vendor directory, but there is an issue with vendor/bin. The explorer in VS Code doesn't see any phpunit files in there, and when I manually go there using the file explorer I see two empty files without extensions. They seem to be broken because I cannot even open them from there. Reinstalling phpunit with composer doesn't change anything. Do you reckon what could be the issue?

[@ProgramWithGio]

Hello 👋. That is strange, have you tried deleting vendors directory and running composer install after?

[@DigitaSkills101]

Bro mine is same

There is no extension but the file works and opens juat fine

[@ProgramWithGio]

Yup, third section is more challenging for sure, so take your time

[@tanjakahlo5255]

Really great content! But in my opinion, very difficult to listen to. The whole video series follows a melancholy tone of reading the text, without a dot or comma, as if everything was read in one breath, which makes it difficult for me as a listener to follow your video tutorials. If you use audio editing programs where you eject parts without voice, to reduce the length of the recording, then you get a robotic audio recording. Maybe my English is not that good, but that is my honest opinion and constructive suggestion to change for the next tutorials.

[@ProgramWithGio]

Thank you for feedback. English isn't my native language so that combined with me speaking fast can be a factor. Also yes I've done wrong audio editing on some videos so that is something I'm gonna get better at 👍. That being said though I don't think "entire series" are like that, just few videos in my opinion. Changing playback speed on KZbin might help a little bit.

Bro, for vscode in Windows 10, the command line for initiating phpunit is "php phpunit --version".

[@ProgramWithGio]

Depends how its installed, maybe on your side its installed globally & the executable is part of the system's PATH variable. Or maybe its just an alias to `vendor/bin/phpunit`.

[@truthteachers]

@@ProgramWithGio Its ok. We have lots of problems with KZbin courses. Most trainers use either the Mac or Linux server and we use XAMPP on windows which works well with VPS servers running CPanel. We try and figure it out or give up on the course and move on. Hehehe..

[@ProgramWithGio]

@@truthteachers XAMPP shouldn't be used in production to be honest. And the OS shouldn't really matter, you can use WSL in Windows and have Linux subsystem. I'm not sure I understand what the issue is with KZbin courses or this specific course. I use Windows in the series with WSL but we use Docker instead of XAMPP, XAMPP we used in 1st section

[@truthteachers]

In my testing (timestamp 23:44), PHPUnit requires the "routeNotFoundCases" method to be static. Is it because i am using PHP 8.1.12?

[@ProgramWithGio]

Did you add @dataProvider routeNotFoundCases to your test method? github.com/ggelashvili/learnphptherightway-project/blob/3.1/tests/Unit/RouterTest.php check this out and compare to your version
