Failure to pick global types

[weidox]

Hello,

With 26.5.3, I'm getting compilation errors in TS files like this "error TS2503: Cannot find namespace" - seems unable to pick up a custom .d.ts file with global type definitions (global/namespace stuff). With 23.1.4 it completely ignores types (could even delete the .d.ts file and ts-jest would work without complaining), which is also not good but at least it works. Am I missing some configuration for 26.5.3, or is there potentially an issue?

The custom type should work as ts-jest e2e test passed https://github.com/kulshekhar/ts-jest/tree/v26.5.3/e2e/__external-repos__/custom-typings

Would you please share your project?

@ahnpnl attached stripped down project to just config and few code lines with .d.ts file and test sample. On purpose left so that tests are executed on both .js and .ts files (change testMatch in jest config). To run test, using "npm run test" - will execute tsc and actual test. If things would be working right, I would not be compiling .test.ts files with tsc at all I think. Test sample is in /src-ts/tests folder, and .d.ts file in /src-ts folder. Also in /src-ts/api folder there's one sample file to see how tsc is able to use .d.ts file in regular code - this one also fails in test in case I modify .test.ts file to not use declarations from .d.ts file.

Probably related #2445

Yes removing outDir fixes this issue. When I made configuration with outDir I remember there was no other way as Strapi was not accepting anything it could not compile in target folders, but by now that issue seems to be gone. Still probably not worth to rework as I can run tests on .js files as well (and existing structure with outDir is more clean). Meanwhile I wonder if #2445 could be fixed so that it does not exclude what's in rootDir.

Yes I will prepare the fix for it soon :)

fixed in 26.5.4
