It's a bit weird to test react components like this - could we change this to simple enzyme tests with a snapshot assertion instead? Then we don't have to call into the internal method.

Does it make sense to rename this to metric_vis_type.test.ts? Just to have a mapping to the file its logic it is testing.

It's fine to postpone these types, but could you create a "dummy type" for it? export type MetricVisMetric = any and then use MetricVisMetric everywhere. By doing so it will get much easier to propagate the type through your code once it's added.

Great idea!

Do we really need this alias? I don't know how much fixtures will be used in the future and IMHO it's better to only introduce these if they are really necessary - just using a relative import seems easier to me. But maybe I'm missing an aspect here.

Yeah, I was questioning whether to add this, but the fixtures files have the fixtures/ aliased paths in them so a relative import still fails. Do you think I should change all the paths in the fixtures files to be relative and get rid of this alias?

Ah good point. @elastic/kibana-operations do you have a suggestion?

IMHO I think we keep this for now until we phase out the fixtures completely. Mainly because I think it's strange to have a path alias in javascript that is not also in typescript.

This LGTM - visualization still works and tests look good.

@elastic/kibana-operations & @elastic/kibana-app-arch could I get a review whenever you get a chance? Thanks

Hey @spalger are you ok with the operations codeowner changes?

tylersmalley

LGTM - really not sure how I feel about the fixtures but can't come up with a better solution.

nickofthyme · 2020-01-17T17:58:25Z

@tylersmalley agreed, ideally we phase them out once the mocha tests are gone. Thanks 👍
