What is Unit Testing, Why We Use It, and Sample Test Cases

Unit testing is a huge part of Software Development, however it's one of those topics that is not easy to understand until you are given some proper examples and context. In this video, we explore a simple test case that prevents some embarrassing mistakes from being introduced into our production application.

Enjoy.

This is a very underserved topic. Thanks for putting out a video on it. All devs need to know this.

[JoseSalazar-cjgd]

I know this video is three years old, but it's very educational about this topic of unit testing. Thank you!

[mattlarsen]

Fantastic and quick introduction to something that is whispered in hushed tones amongst junior developers.

Brian Voong you are to iOS what Andrew Ng is for Maching Learning : concise, clear, and brilliant !

[ChordToday]

Not aa iOS programmer here but your video explanation is so clear that I understand the concept anyway. Thank you!

[maklasik]

Not even coding in swift, but very interesting to watch. This channel is awesome. Talking about very important stuff for newbies. Much appreciated

[adamsmidov]

First time I see such a simple way for the explanation. Great!

[anshuparihar]

Nice, elaborate and to the point. Need some advance examples but for gaining basic understanding this is superb.

First I heard of built in test functions. Reminds me of sales force development. Thank you.

I have a second interview in about two hours, thanks for this video! Wish me luck!

[utberoxsobad]

Yes please! Can you make unit testing videos! Especially for networking and requests and model objects as well!!

[syedaurangzaib]

This topic is most important for us. I understand it clearly, because your teaching method is great :)
please also make a video on test case for web services, api testing.
I'm waiting for your kind video.

I don't use swift, but this was a really helpful primer on unit tests! I've worked at too many companies that don't see the value in them, so I'm working hard to start integrating them into our code base

[arkter]

Some of your videos made me convince to learn programming. Thank you! :)

[yonasstephen]

I never bother to learn what's that UnitTesting in Xcode for before. thanks for this! nicely put along with real-life example use case. now that you mentioned about Continous Integration, would be great if you could talk more about it in your next video, what tools you're using, and so on! Cheers

[marcaupont]

Very nice! I like the new effects! It gives your videos a polished look

Unit testing is a way of testing one unit of a software application. A unit is the smallest piece of software that is isolated and tested as an individual for functioning. Avo Automation provides the best automated testing platform for all types of software testing, including unit testing

I really liked this video. I am relatively new to testing, and find it a big challenge sometimes, especially when it comes to UI. Can you do some more complex testing tutorial as well please?

[krutomjer]

Great video Brian, I always thought that testing is tedious but this really makes it logical and appealing.

[rl-pavel]

I would *love* to see more videos about Unit Testing! Keep it up, please!
