Just a shoutout: mix mneme.watch is amazing

Thank you for saying so! I’ve been wanting to record a new quick demo using it, but have some family in town and so haven’t had time.
I also want to write up some suggestions for its use when I’m able. For instance, I’ve found that I prefer to use it with a single file (mix mneme.watch test/my_lib/some_test.exs) or even a single test (mix mneme.watch test/my_lib/some_test.exs:123) so that it runs really quickly. I plan to add an --exit-on-success flag that would facilitate this even more!

What about mix mneme.watch --stale (`mix mneme.watch`: add flag to only run stale tests · Issue #91 · zachallaun/mneme · GitHub)
Isn’t that magical, it already works

v0.9.4 is now available
This release adds mix mneme.install, an Igniter task for setting up Mneme in a project. Setting up Mneme is now as simple as:
- Add the dependency:
{:mneme, ">= 0.0.0", only: :test} - Fetch dependencies:
mix deps.get - Set up Mneme:
MIX_ENV=test mix mneme.install

With that installer defined, if folks are already using igniter, then
MIX_ENV=test mix igniter.install --mneme --only test
should also work, right? If you put only: [:test] in your installer, then just MIX_ENV=test mix igniter.install --mneme would also work. Additionally, mix igniter.install --mneme would yell at the user telling them to rerun in the test env (if you had only: [:test] in your installer).
Not saying you should make that part of your instructions, it’s your library so you do you 
Just offering it up in case you’re unaware. But I would suggest adding the only: [:test] option to your installer’s info so that it properly yells at users who use mix igniter.install mneme, which is quickly becoming my default way to add packages

I believe it should, yes! At this point, I’m not (yet) assuming that folks will be explicitly using Igniter, so I want the first steps people to see to be the ones you need if you don’t have Igniter installed.
That said, the tip about only: [:test] is great! I didn’t know about that feature and will update the installer to use it.

@zachallaun maybe I’m missing something, but I don’t seem to find in the docs how to run mix test with action: reject. Is the only option to set the CI env variable?

From the command line, at the moment, yes. Right now, options can only be set in code (except for CI). I can definitely see the use for it though and would be happy to explore a more general env var that could set arbitrary options. Something like MNEME_OPTS="[action: :reject]" mix test.
