FR: change print-invocations plugin to put all invocations on one line

[NoahTheDuke]

Currently, when you have multiple failures, the :kaocha.plugin/print-invocations plugin will print each failed test on its own line:

bin/kaocha --focus 'kaocha.history-test/example-one-test'
bin/kaocha --focus 'kaocha.history-test/example-two-test'
bin/kaocha --focus 'kaocha.history-test/example-three-test'

This is because the plugin is implemented with a doseq:

kaocha/src/kaocha/plugin/print_invocations.clj

Line 16 in 9d5bb81

(doseq [test (testable/test-seq results)]

Given how long it can take to start up a Clojure program, I'd like it for all of the invocations to be bundled into a single call:

bin/kaocha --focus 'kaocha.history-test/example-one-test' --focus 'kaocha.history-test/example-two-test' --focus 'kaocha.history-test/example-three-test'

If this is acceptable, I can open a PR.

I can see arguments for both behaviors, the idea with the current implementation is that you would tackle these one by one, hence the separate invocations.

Edit: Let's see if we can get some second opinions on this, or folks can vote with 👍 / 👎 .

Would it hurt to output both?

[plexus]

It's already quite noisy as it is...

This could be a configuration. Default to current behavior, add :kaocha.plugin.print/format :one-line or something. It complicates the implementation a smidge, but I can fix that.

[imrekoszo]

I like the config idea. The two print styles are both useful but for different purposes.
