You explain the Mock in unittest that very easy understanding, you have reproduced difference use cases are very important to understand!! Thank you so much!

[@GaryClarkeTech]

Welcome! Glad it was helpful!

[@GaryClarkeTech]

Thanks Archaf..I appreciate the kind words. More to come soon!

Yes I also trz my best on it and hope that will work

Thanks for this great video. So basically when we type hint the return type of the method that we're testing, and we call it on the mocked object we'll get null casted to that type.

[@GaryClarkeTech]

Exactly that

i want to hit the like button for every test passed. Thanks, the best tutorial available on this subject.

Ty Gary!!

[@GaryClarkeTech]

Welcome 👍

[@NeverCodeAlone]

Thx a lot for your work here.

[@GaryClarkeTech]

My pleasure!

[@МухаметджинТимур]

Thanks for video. I have one question: how can i test the private or protected methods of class which return void?

[@GaryClarkeTech]

There are a couple of ways... 1) Don't test them in isolation...only test the public API of the class 2) Use Reflection to make the method accessible

[@МухаметджинТимур]

@@GaryClarkeTech thanks!!!

[@NeverCodeAlone]

Makes this sense?

[@parijke]

Nice Gary

[@wisamalkhatib4020]

Hello would you please explain how to mock protect method and return specific value

[@GaryClarkeTech]

You can use Reflection to make methods public on the reflected object..BUT...I don't recommend doing that and recommend that you just test your public API. I cover this in the full course.

[@wisamalkhatib4020]

@@GaryClarkeTech Hello Thank you for your quick reply in Reflection i get the method and set as pupblic method what should i do after that ? how can i say return true because this protect method calle an api to return bool value

[@qkenkenu]

What you do @Gary Clarke - is defenatly amazing, I'm watching carefully tutorials where the key feature is to make "TESTS", and have no idea what the test are really needed for? Maded to check, is sometching that we anyway overriding each time will bring proper value? I dont know, are test are bringed to life just because to keep programers at work ???

We have a PDO class at work that takes care of creating a PDO db instance. Is it possible to mock that?

[@GaryClarkeTech]

Yeah..if you own it, I don't see why not. It won't work if it uses a static factory method to do this though...you can only stub instance methods.

[@NeverCodeAlone]

Very nice video thx a lot

[@markwilkinson276]

I have a trait which is used for handling HTTP requests. Is it possible to mock and test a trait? Really like your video and have been able to apply it so far for other areas of my app, but now I've hit a wall where I'm unsure how to handle traits. It's worth noting that I have a get() method which calls a protected makeRequest() method inside it - is it possible to test nested method calls? Again, can't think how this would work

[@GaryClarkeTech]

Yes..you can stub all of the public, non-static methods of your class, even if you are getting them from traits. Testing a nested protected method will require a bit of imagination...also consider refactoring for testability. Lots of that kinda stuff in the full course!

[@lmartyn]

This is great. I know and use it now, but wish I had known sooner

[@GaryClarkeTech]

Cheers Łukasz..bookmark it, it will come in handy as a reference 👍
