This pull request introduces important error resilience tests for the ContributorsClient component, which is a great step towards improving the stability of our application. It aligns well with our previous decision to implement similar tests for the ContributorsSearch component, ensuring that we maintain a robust user experience even in the face of errors. Thank you for your contributions, and I look forward to your updates!

Hi @Aamod007 Sir,

I verified this test locally:

✅ npm test -- ContributorsClient.error-resilience.test.tsx passes (5/5 tests)
✅ ESLint passes for the new test file.

The CI failure appears to come from existing TypeScript errors in:

app/generator/components/EditorPanel.type-compiler.test.tsx
app/generator/components/PreviewPanel.type-compiler.test.tsx

These files are unrelated to the changes in this PR.

Hi @Aamod007 sir, review it.

Nice work adding the error resilience and mock integration tests for the ContributorsClient and CustomizeCTA components. However, this PR is currently blocked due to a failing CI check. Please resolve the issues and rerun the CI pipeline.

Hi @Aamod007 sir, please review and merge it.

The mocks and error resilience tests in \ContributorsClient.error-resilience.test.tsx\ look great. However, this PR contains a duplicate file from PR #8090 (\CustomizeCTA.mock-integrations.test.tsx). Please rebase your branch onto \main\ so that this PR only contains your new tests for \ContributorsClient.
