Bug: ng test fails to run because of ng-mocks error after upgrading to typescript 4.8.2

Description of the bug

With devDependency on ng-mocks 14.2.0, after upgrading to typescript 4.8.2, ng test fails to run with the following error:

Error: node_modules/ng-mocks/index.d.ts:1447:112 - error TS2344: Type 'C' does not satisfy the constraint 'Record<string | number | symbol, any>'.

1447 export interface MockedComponentFixture<C = Record<string | number | symbol, any >, F = DefaultRenderComponent<C>> extends ComponentFixture<F> {
                                                                                                                    ~

  node_modules/ng-mocks/index.d.ts:1447:41
    1447 export interface MockedComponentFixture<C = Record<string | number | symbol, any >, F = DefaultRenderComponent<C>> extends ComponentFixture<F> {
                                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    This type parameter might need an `extends Record<string | number | symbol, any>` constraint.

Everything works fine just downgrading typescript version to 4.7.4

Hi @fagia,

Thanks for the report.
Please, provide a min repo with the issue.

Hi @satanTime
thanks for your answer, I've been able to reproduce the same issue with ng-mocks repo itself:

• check-out master
• in package.json update the typescript dependency to 4.8.2
• npm run build -- --prod
• same error will happen

I've also tried to make few changes to ng-mocks sources to make typescript 4.8.2 happy...they seem to work but, since I do not have the full context, I'm not sure that they would not be breaking anything else... in case, the changes I've tried are attached here:

v14.2.1 has been released and contains a fix for the issue. Feel free to reopen the issue or to submit a new one if you meet any problems.

Cool I can confirm that it's now working fine!
Thanks @satanTime for the quick and effective fix
