16:16 "I need to mock a function" Higher Order Functions
20:30 "I need to mock a function" Monkey Patching
22:55 "I need to mock a method on a type"
25:55 "Accept interfaces, return structs"
27:00 "I have a large inteface, I need to mock a small set of its methods"
29:15 Embedding can be a hole in the type system

Well done Kyle. As old as this is, it is so relevant and very informative. I love the 'large interface - small set' test. You have opened my mind to a pattern I can use even beyond mock testing. Have an air coffee on me. Thanks dude and be blessed.
The monkey patching thing is fire 🔥
Wish I saw this video a year earlier when I started learning Go. My first language for work env is Go. And even after a 6 months I was not sure about unit testing in Go. This is really helpful for beginners!!!
Probably the best explanation of the golang mocking on the web. Thank you!
excellent talk. Excellent comments. Excellent points. Excellent wisdom
2024 still super super helpful
Invaluable video. Thank you
Great talk!
Just to mention that nowadays gomock is archived, but Uber maintains a fork.
A gem of a video
Thanks for watching!
Kyle, it is really really helpful. Thank you.
Glad it was helpful for you!
Thank you so much Kyle Host for this superb unit testing video.
Is there any way for testing channels, signals, goroutines, locks.
Just got what i really want to know
EDIT: Looks like you get to this at the end of the talk 😂. If you have a large interface and you need to test just a few of the methods then you need to be writing more SOLID and idiomatic go. "Interface Segregation Principle revolves around the idea that clients should not be forced to rely on methods they do not use. To achieve this, the principle suggests creating specific interfaces or classes tailored to the needs of individual clients."
What IDE is he using when doing the demo? I usually just use Vim, but I'm considering my options. It's visible at czcams.com/video/LEnXBueFBzk/video.html

How about not mocking
