[TEST] Add ToastContext unit tests for auto-dismiss behavior

[utksh1]

Summary

Add focused tests for toast lifecycle behavior.

Scope

• Test adding success/error/info toasts.
• Test manual dismiss.
• Test auto-dismiss using fake timers.

Acceptance Criteria

• Tests use the existing frontend test setup.
• Fake timers are cleaned up after each test.
• No production behavior changes unless the tests expose a small bug.

Hi @utksh1 👋

I would like to work on this issue under GSSoC'26.

I will add focused unit tests for the ToastContext lifecycle behavior by:

• Testing success, error, and info toast creation flows
• Verifying manual dismiss functionality
• Testing auto-dismiss behavior using fake timers
• Ensuring timers and mocks are properly cleaned up after each test
• Keeping production behavior unchanged unless the tests reveal a small issue that requires correction

I’ll make sure the tests follow the existing frontend testing setup and remain clean, reliable, and maintainable.

Please assign this issue to me. 🚀

Hi @utksh1 ,
I’m a GSSoC 2026 contributor and I’d like to work on this issue.

I plan to add focused unit tests for:

• success/error/info toast creation
• manual dismiss behavior
• auto-dismiss functionality using fake timers

I’ll also ensure fake timers are properly cleaned up after each test and keep the implementation aligned with the existing frontend test setup. Please assign this issue to me if available.

Hey @utksh1,

I went through the issue and I’d like to work on it under GSSoC’26.

I’m planning to add unit tests around the ToastContext flow, especially for auto-dismiss behavior with fake timers, manual dismiss, and different toast types like success/error/info. I’ll also make sure timers are cleaned up properly after each test so the test suite stays stable.

Would love to contribute to this one if it’s still available 🙂
