Add `IsProgram` mock method to `MockGLESImpl`, use it in `BufferBindingsGLESTest` by b-luk · Pull Request #192196 · flutter/flutter

b-luk · 2026-09-02T18:36:40Z

Previously, this method was not mocked and would return an undefined value when it was called in the BufferBindingsGLESTest unit tests. When the returned value happened to be false, this makes the tests fail. We've seen this failure pop up multiple times recently.

Examples:
https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20linux_unopt/47431/overview
https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20linux_unopt/47434/overview
https://ci.chromium.org/ui/p/flutter/builders/prod/Linux%20linux_unopt/19763/overview

I can't consistently repro the failure at HEAD or at the PRs which produced the example failures. But I I tested that modifying this PR to return GL_FALSE instead of GL_TRUE does consistently reproduce the failure.
