I took your Double Your Coding Speed course back in late 2014 / early 2015. I knew you were a rising teaching star when saw how well you presented the course. Every course of yours that I enrolled in since then has been top tier.

[dbassett]

I love that you can actually watch these videos on mobile. Too many other channels don't zoom in on the code window.

Mosh I'm really glad I stumbled across your videos, you're really awesome at teaching how to code, I'm looking forward to keeping up on your videos on your web site.

Thanks for this video, Mosh. Also helpful as an introduction to unit testing in general, independent from any programming language.

24:25 You can run a single test with right click in the body method.

It's a very long video but every second of it is totally worth it.

I watched the entire video and I'm hyped about the full course. Maybe I will buy it....

[hollyferree]

excellent! i was riveted/invested the entire time. excellent pace ! excellent information while showing examples. watching all your videos !

[jorgepiantini]

You have no idea how helpful this video was for me. Every single part of it was awesome, I understood everything and you make it seem way easier than I thought. Thanks for sharing!! (I know that its a year later but It still being useful :D)

[yougiely]

the only channel that do not provide tutorial without being boring.

[nithyas]

Really got a very clear idea on what is TDD !! Thanks Mosh

[Hudgi]

You actually can run one test at a time in MSTest inside of the test explorer window

[mohdotnet]

Thank you so much Mosh, easy to understand, and totally increased my understanding

[pathofmaximumresistance]

The entire lecture is helpful. But there is an awesome little tidbit around the 32-minute mark that may be obvious to more experienced developers but less so to junior folks like me: Well defined and properly named unit tests can help developers new to an existing code base quickly understand the intended function of the classes being tested.

It is possibly common knowledge to most but 'edge cases' (10:20) is testing for extremes of possibility when interacting with your program, like input values which are technically legal but are highly improbable - the effective power bug on iPhone was due to a bug from an unconsidered edge case of text message input

[Gowthamreddykunduru]

you can run/debug single test, Right click in the method body, u will get both Run Tests/Debug Tests (ctrl+R, ctrl+T)

[jaythanki]

Hey Mosh, it seems like your Dropbox link for the Source code is not curretnly working. Can you fix it for me ?

[tryfanevans]

Been looking for something like this all day, it's all super basic and is just throwing exceptions or it's some crazy mess of tools. I can finally get to work on adding unit tests.

[glennpavel]

great video, i have a little question!! how a Test controller if a use session variables in ther constructor, or is possible to simulate a session? thanks for all!!

[JayRGabz]
