Refactor : scripts/__mocks__/@pdfme/generator.test.ts from jest to vitest

Is your feature request related to a problem? Please describe.

This file is currently tested using Jest. As part of our migration to Vitest, we need to refactor the file's test cases to align with Vitest's syntax and features.

Acceptance Criteria

1. Replace Jest-specific functions and mocks with Vitest equivalents
2. Rename the test file from having a .test.* suffix to a .spec.* suffix
3. Ensure all tests in the file pass after migration using npm run test:vitest
4. Maintain the test coverage for the file as 100% after migration
5. Upload a video or photo for this specific file coverage is 100% in the PR description

@syedali237 There appear to be flags related of jest and combined still in codecov . I think there are few references of them andremove them and make only one flag or else remove flags too

[syedali237]

@varshith257 ok assign it to me.

[syedali237]

@varshith257 should i also remove the "test" script from the package.json that runs jest test cases?

[syedali237]

and also all the jest devDependencies mentioned and also remove jest anywhere mentioned in a file?

[varshith257]

Yes, remove it and replace with vitest

[palisadoes]

@syedali237 @varshith257

Do any of these files need to be updated too? There are multiple references to jest related packages

[varshith257]

@syedali237 Remove them we also have equivalent exact syntax in vitest for mockResolveValueOnce etc..

[syedali237]

@varshith257 should I open a new issue and raise PR for it, as it includes removing dependencies as well?

[varshith257]
