Today, Kilo Loco covers how to get started with unit testing using XCTest in Swift.
He will cover how to refactor code out of view controllers, what code is best to start testing, and how to implement several different unit tests using functions like XCTAssertTrue and XCTAssertEqual.
Anyone looking to reduce the amount of bugs in their code and increase the amount of code coverage in their codebase should watch this tutorial.

you had me with "Real World ....", there are thousands of videos with iOS content, but it is always the same and with very basic examples, it is what the community lacked, more content creators who gave real examples , with context. And with your charisma and way of teaching it becomes very easy to understand everything. I discovered your channel recently, and you're already one of my favorite swift devs! I wish you success in everything you do !!!

@Kilo_Loco 4 года назад

Thanks Felipe, I really appreciate it!! I'm definitely going to be focusing on real world examples more often, so hopefully you continue to enjoy the content that's on its way

@TheHy6xD 4 года назад

I love your IDE setup and theme, I remember those days a few years ago when I just was learning from you and now I work full-time. Thank you, Kyle!

@SudhanshuSrivastavaIndia 4 года назад

I think this is the most detailed and practical video on Unit Tests.. Thanks Kilo

@Kilo_Loco 4 года назад

Haha Glad you liked it!!

@immmax 2 месяца назад

Thanks for this video. Good clear way to dive into testing. 👍

@BharathGuntupalli 5 месяцев назад

Comprehensive at the same time more detailed. Thanks for making this video, this helped me a lot :-)🙂

@mikaelacaron4694 4 года назад

Great tutorial Kyle! I just started learning Unit Testing. Loved the real world examples!

@Kilo_Loco 4 года назад

Hahaha Glad you liked it Mikaela. Also hmu if there are topics that you want covered. You've been following for a while now and i would like to return the favor of you supporting the channel

@xtcrpk9316 4 года назад

The second part of testing video would be great! With some more specific use cases and real life examples (more complex, mb?) But yep, thanks for the video, its just in time!

@Kilo_Loco 4 года назад

I'll definitely do more on testing. Looking to get into other real world examples

@sashamakedonskii 4 года назад

@@Kilo_Loco It will be nice to test network calls 👍🏾

@finalpets 4 года назад

Love it!, maybe UITest and one more UnitTest but with MockUp Server, will be more realistic because every APP has a network request and its hard to Unit Test that Layer, thanks!!

@bdaralan 4 года назад

Learnt capture error in assert throw and how to check code coverage. Thank you. 😃

@Kilo_Loco 4 года назад

My pleasure!! Hopefully I can keep providing you more value in the future

Haha glad I could help 😁

@sorinmiroiu9404 4 года назад

Very cool video Kilo. When i heard the words "reusable code" i thought to myself "now, that's sexy". Keep up the good work and i hope you have a great experience at your new job. :D

This is an excellent video Kilo!

@Kilo_Loco 4 года назад

Thanks!! I'm glad that you liked it! Now make sure you start adding in tests to your project 😉

@shiaulis 4 года назад

In some TDD approaches "validation" will be called as "sut" - system under test. Sometimes it is convenient to see a system under test in any test file. But anyway thanks for those examples, true help for beginners in unit tests

@Kilo_Loco 4 года назад

Yea, I considered using the word sut, but I figured it would cause more confusion than simply giving it the name “validation”

@ianrust3785 3 года назад

Thanks, very clear and practical.

Love the video and I love your IDE setup + theme. But I don't know how to configure my IDE like that As control + shift + enter does not work on my side 😫

@TheFloydPinkus 4 года назад

Another great video, we learn so much. Just one thing I was missing - that KIlo Loco talk you do in a lot of your videos. You we're a bit too serious this one :)

@Jock3R87 4 года назад

Mate firstly many congrats on your new job... any thoughts on Protocol oriented programming using Dependency injections ... which is in demand

@Kilo_Loco 4 года назад

Yes, I think that protocol oriented programming is a very important concept, especially for making things easier to test. I actually put together a course on POP kilo-loco.teachable.com/p/pop

@Jock3R87 4 года назад

Kilo Loco mate I am UK based so not sure how can I enroll for this...

@666MrGamer 4 года назад

Nice video! Definitely helpful for beginners and a great starting point. Just a suggestion - I would make the XCTAssertTrue(username.count == 20) change to username.count >= 20 that way the test is less restrictive and does not fail for even longer usernames. Also I think testing the expectedError description is redundant. Since the above XCTAssertEqual will only pass when the error and expected error are of the same type it implies that the descriptions will be the same. I would probably just check it against a struct that keeps hold of all the app messages and test it against that. That way we test if we have the correct message for each error.

@Kilo_Loco 4 года назад

Thanks for the tips, I appreciate them 😊 Yea it definitely would have been better to do >= 20 to future proof it a little more. As for the error description, it definitely is redundant, but I thought it would be a nice way to show how to chip away at the coverage. Also, I think there are instances when things like this could actually be useful due to inconsistencies caused by conformance/inheritance

Woooow awesome man! Do you have any plans for a UI testing video?

@jakubgawecki4264 3 года назад

Hey guys. I am still in the phase of getting to know unit testing. Can anyone explain to me what was the purpose of creating methods, then checking them in a simulator, and then, after all, writing tests. Should tests not be done first? What I mean is, if we testing in a simulator first, what is the purpose of further testing in a Unit testing case? Thanks!

@am13476 4 года назад

Can you create more videos about Unit Testing, especially about API testing, network calls etc

@Kilo_Loco 4 года назад

Absolutely

@prahladreddy6839 4 года назад

Hi kilo, can you make more n more videos on unit testing please

@Kilo_Loco 4 года назад

Absolutely! Which aspects of unit testing are you interested in?

@denisp.7850 4 года назад

thank you, Kilo 🤛 btw is it me or there's something wrong with the sound? it seems to be shifted a bit to the right.

@Kilo_Loco 4 года назад

Hmmm I didn’t notice it but I will definitely try to be more vigilant in the future to make sure this doesn’t pop up

@galahador 3 года назад

Very nice!!

@jessie5096 3 года назад

how to unit test without the simulator show up and running? Thanks

@harshhungund5556 3 года назад

Great tutorial Kyle. The best to get started on Unit Testing with practical scenario example. Request you to please make one on UI testing as well. If already made then can you please share the link of that video 👍

@sathishkumardsk 4 года назад

Hey can you do a video about NSOperationQueue?

Yes I most certainly can!! It’s on its way soon 😉

any chance of you covering more in unit testing but with mocking a protocol (interface)?

@Kilo_Loco 4 года назад

Yes!! More unit testing is on its way 😉

@javedsiddique6016 4 года назад

hi I want tutorial on generics like we have. function with parameter as sturture object and as per tht when we call function it should parse the data as per the type we want do database or some other functions as per that structure type we want

@Kilo_Loco 4 года назад

Great topic to cover. Thanks for the suggestions
