Exclude mocks and Cypress specs from eui.d.ts

[cee-chen]

Summary

Per @1Copenut's upgrade Kibana PR (elastic/kibana#119205), the checks step is failing with this error:

ERROR Type check failed in test/tsconfig.json:
ERROR node_modules/@elastic/eui/eui.d.ts:17870:31 - error TS2503: Cannot find namespace 'jest'.

It looks like there's a TypeScript export issue that I traced back to row_height_utils.ts (datagrid mock) and line 17,864 of the eui.d.ts definitions file.

Mocks should not be exported in our eui.d.ts file, nor should any other test files. I've updated our dtsgenerator.js config to exclude all possible mocks, as well as Cypress spec files just in case.

Checklist

• Test against local Kibana somehow before patch release??

Confirmed locally that eui.d.ts does not contain any mock or spec files (and therefore no jest), and compared to main which does have mock file references.

You could use the upgrade PR branch and just replace the eui.d.ts and run the type check. Shouldn't even need a full EUI build.

I can confirm that on latest main's eui.d.ts I can Ctrl+F for jest and find the __mocks__/row_height_utils file:

On this branch when I run node scripts/dtsgenerator.js, the above lines are now gone. I additinally do not see any .test.* or testenv files still so I think my file extension glob change is also safe.

Haha, Greg's 2 fast and 2 furious

Bootstrapping the upgrade PR branch now, may take a while. If we're confident this works and would rather start the patch release process now I'm good with it

Edit: beat by Greg! ❤️

Confirmed mentions of mock are gone from eui.d.ts after running the dtsgenerator script. Spot checked the ts+tsx->{ts,tsx} format change works as intended.

For this I usually copy & paste the generated eui.d.ts into Kibana's node_modules/@elastic/eui/eui.d.ts and run the type checker.

OK, pasted eui.d.ts and ran node scripts/type_check in Kibana and the 4 ts projs that are failing in Trevor's PR are passing locally.

(Unrelated: I saw type failures related to my EuiCodeBlock refactor which I'll shortly push up a fix for - it's in unreleased main and not in the 41.2 release so should be fine to not include in the patch).
