📔 Objective

Increases the -maximum-test-execution-time-allowance xcodebuild flag from 1 second to 2 seconds in both test.yml and test-bwa.yml.

Parallelized Swift Testing tests can exceed the 1s limit under system load caused by the parallelization itself, resulting in spurious CI failures. Raising the limit to 2s gives those tests headroom without masking genuinely slow tests. Parallelization is a net win for overall suite speed, so the right fix is a slightly looser timeout rather than reverting parallelization.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR raises the xcodebuild -maximum-test-execution-time-allowance flag from 1 second to 2 seconds in both .github/workflows/test.yml and .github/workflows/test-bwa.yml. The change is symmetric across both workflows, the rationale (parallelization-induced contention causing spurious timeouts on otherwise-correct tests) is clearly explained in the PR description, and the new 2s ceiling still preserves the intent of catching genuinely slow tests. No security, correctness, or breaking-change concerns identified.
