Thanks for making this as accessible as you are! I would love to see more practical pieces on TDD, especially for the web.

How will you be sharing the source code? I would love to see TDD happen with a test committed followed by a commit to pass the test, etc. to get a sense of the full process or write my own passing code for each test and compare against another implementation.

I have started doing this for my training courses. When I demonstrate live, I commit to git. I use some variation of "FAILING" in the commit messages to call attention to "red" commits, in "violation" of the usual rule that tests pass 100% in all commits.

azundo, I know my examples aren't web apps, but do you have time/energy to explore any of the branches in this code base[1], read the commits, and give me feedback on how easily you follow it?

Will also take a look and let you know! I'm not a serious java dev but can usually parse a bit of code here and there so will try and get you some useful feedback.

You're welcome! I haven't decided how I'm going to share source code. For my current series, I'm committing after every episode and posting on GitHub [1], so I'll do at least that much. Your idea of committing after every step of the TDD cycle is a really interesting one, but I'm not sure if could do that without it detracting from the videos. I've added it to my list of neat ideas.

Hmm... thinking about this further, it shouldn't be too hard to have a wrapper for my build script that stores the most recent pass/fail state, then automatically commits when that state changes. The trick would be not polluting the continuous integration or end-of-episode branches. I'm sure it can be done, but my git-fu is weak and it would take some research. Might be a good stretch goal reward if funding goes well...

Thanks for the reply! Good luck with reaching the funding goal - interested to hear how things go and if you do work out a way to get the build script working as well.

Okay, I did it. :-) I'm not sure how useful/readable the result is, but check it out and let me know what you think.

Awesome! Thanks for making this happen. Have downloaded the git repository and will take a look soon.

Maybe this: in "draft mode", you automatically commit on all changes in pass/fail state. Then, at some point, you "publish", at which point you squash all the commits from commit X to HEAD whose message matches "[ON RED]".

I imagine git rebase -i X | sed -i "magic happens here" would do the job.
