store/index.js tests don't run on `npm run test`

[subtle-byte]

Describe the bug

test/store/index.js tests don't run on npm run test.

Seems like any non index.ts does not run due to this line in the test/test.ts:

const test_folders = glob('*/index.ts', { cwd: 'test' });

To Reproduce

I've made one test in test/store/index.js always fail and got following result:

Tail of `npm run test` output

Then I've replaced the line with const test_folders = glob('*/index.{js,ts}', { cwd: 'test' }); in test/test.ts and got following result:

Pay attention now there is store section after stats and before validate.

Expected behavior

All tests run on npm run test.
