How to fix TypeScript compilation error?

Question

typescript

For a long time I did not study ts and for a long time I forgot what and where. Now it is necessary to return to my old craft... When assembling the project, everything is clearly assembled - no problems, but if you run npm testit for some reason, it gives out this:

TSError: ⨯ Unable to compile TypeScript:
src/plugin/modules/model.ts:7:13 - error TS2304: Cannot find name 'Settings'.

settings: Settings = {

The script itself npm testexecutes the following commands:

[email protected] test /Users/nikita/Desktop/работа/FSD-plugin
mocha -r ts-node/register src/plugin/tests/*.ts

I posted the whole project on github: https://github.com/burningyouth/FSD-plugin

Maybe someone knows what the problem is? Why does not see interfaces? I have them in src/plugin/@typesand during normal assembly everything is OK, but the tests do not work. It seems to me that the problem is that when compiling @types is taken into account, but not when testing. I'm clearly missing something, and the obvious, but I don't understand what.

UPD: Tests work if you remove the Settings interface. And if this interface is put directly into a file, then everything is OK ... So mocha simply does not see my interfaces.
