tests: Add test for avatar error placeholder.

vinodsingh-dev-gsoc · vinodsingh-dev-gsoc · commit 3f692092dae8 · 2025-10-02T12:05:41.000+05:30
This adds a new test case to verify the behavior of the AvatarImage widget when the avatar URL fails to load.

The test uses HttpOverrides with a MockHttpClient to reliably simulate a network error. It then asserts that the expected placeholder widget (identified by its icon, ZulipIcons.person) is rendered, ensuring the error handling is working correctly.
