Thanks for the contribution. I went through the changes and the overall approach looks good. The implementation adds solid test coverage for edge cases involving large translated strings and repeated rendering under load.

Labels Applied:

• \level:beginner: This PR is a self-contained addition of a single test file that mocks context effectively without deep architectural coupling.
• \ ype:testing: The sole purpose of this PR is to add unit tests.
• \quality:clean: The tests are readable, well-structured, and use the standard mocking approach for this codebase.
• \mentor:Aamod007\

Once again, great work on these tests!
