Should we provide a package/api like create-jest-ruuner.
It will make writing custom sequencer easier.

Thank you for the great work here!

We've released 24.6, so could you merge in master, and ensure version numbers are correct and that the changelog entries are in the correct place? Happy to merge after that!

WeiAnAn · 2019-04-02T08:14:19Z

Merge 24.6 and update version number to 24.6.0.
Thank you everyone to help me complete this PR.
I learned a lot from this experience.

jeysal

Thanks a lot @WeiAnAn, I think this will make a lot of people in #6194 happy 😅

+Sort test path alphabetically

+const Sequencer = require('@jest/test-sequencer').default;


This could do import Sequencer from '@jest/test-sequencer'; instead to avoid the .default part. Fine as-is though

Thanks @WeiAnAn!

This value doesn't get fully resolved unless explicitly set, so it cannot work with PnP. It should be done like here: https://github.com/WeiAnAn/jest/blob/301a5cda50bf82617fe776938ee3fbd1c24b4a7c/packages/jest-config/src/normalize.ts#L477-L479

We resolve it in normalize already don't we?

I'm checking, but I think it only get resolved when the testSequence option is explicitly set - otherwise it uses the default value as-is.
