Wow! Thanks so much for the rapid response! This is exactly what I was looking for! I'll give it a go, and once I have a working version, I'd be happy to create a PR for the update to the docs.

Cheers!

Hello @tlowrimore!

Thanks for using LightService.

We created the ContextFactory helper for "segmented" outside-in tests. Meaning, when we had 5 actions like this:

[Action1,
Action2,
Action3,
Action4,
Action5]

and we wanted to test Action4, (we had to have a lot of data in the Context, and since we talked to the database anyway as it was fast with database_cleaner transactions) we just executed the pipeline up-to Action3, and used the context in that state at that point in time.

In case you want to call one action in isolation, you can invoke it via the execute method.
See this example for it.

The Context is a more specific Hash, you can initialize it with LightService::Context.make, like in the spec, and then you can add any items your action needs. Invoke execute on your action and assert on the items in the resulting Context.

I am thinking this would be a good paragraph in the README. In case someone would contribute with a small README pr.

Hth.

I had 30 minutes free, so I thought I'd add some docs into the readme about how to run actions in isolation, that led to me turning it into a small "Getting Started" section.

I already have a PR open #194 so I thought I'd sneak it in there, even though it's not strictly related to the PR's content. @tlowrimore, let me know if you'd like me to add anything to the readme. You can see the changes here: 3fe6a63
