justforfunc #16: unit testing HTTP servers

Let's cover the basics of unit testing in Go and then show how you can test http.HandlerFunc and http.Handler.

You'll learn how to use "testing", including subtests and examples, and "net/http/httptest" with ResponseRecorder and Server.

One of my favorite things about this series is seeing the collection of stickers grow each video.

Wasn't expecting to find a video on exactly what I was looking for, but I did. Thanks for the video! One of the live coding videos I've seen.

Extremely informative video and still holding its value very well as time goes on. Thank you very much for taking your time to help grow the gophers!

Hello, Francesc.

Thanks for the video. It helped lot to get into basic testing.
Can you please record a video how to mock Handlers dependencies that can be anything like connecting to database or invoking external API's and like so.

I love it! Keep up the good work. As a new programmer working with Go, deep dives into the basics of the language are extremely helpful.

i miss this series. i wish there was one that was comparable. justforfunc RULES!

This is really excellent! One tip I discovered just yesterday: if you put "localhost:8080" instead of ":8080" into your ListenAndServe method, it will make that annoying MacOS popup go away (but only after you've run it once)

I learned more from this video than any other tutorial on testing that's currently out there. Keep up the good work! Let me know if you have a Patreon account, I would like to donate.

This series is wonderful. I watched it first in 2017 and I come back from time to time. I also use a similar approach to testing and error handling in C now, since my job doesn't allow me to use golang, but it's super effective.

Been coding in go for 3 years, still picked up some tricks! Great content, thanks!

Excellant video my man. Your channel has been recommended to me, so far, I like your style and topics.

[blondie]

I really enjoyed this episode particularly. I have not been writing tests in my code. It was interesting to see how to write tests for network services that I assumed you couldn't easily write tests for. I learned allot.

[leffenx]

Just a great joy to learn from this series :-) Thanks for providing nice tutorials !

[Trammael]

This is the clearest explanation I've seen, thanks! (or read :) )

[marcoazevedo]

Awesome episode! I had no idea about this way to test router. Thank you so much for this video. By the way I'm really enjoying to learn Go. It is not only pragmatic and fun but also have an impressive and powerful standard library.

[JorgeGomez-xcer]

Very good explanation bro, congratulations!

[plaguewielder]

great one and it helped me a lot, thanks, but why your last video is for 5 years ago? where are you?

[AshwiniKondalakadu]
