fix: log seed when only `sequence.shuffle.tests` is enabled by kaigritun · Pull Request #9576 · vitest-dev/vitest

kaigritun · 2026-02-03T05:24:21Z

Summary

This PR fixes #9557 where the seed is not logged when only sequence.shuffle.tests is enabled.

The Problem

When using the config:

sequence: {
  shuffle: {
    tests: true
  }
}

The seed was not being logged, even though it's used to shuffle tests within files.

The Fix

Two changes:

In resolveConfig.ts: Set the seed when either files OR tests are shuffled
In logger.ts: Log the seed when either files (RandomSequencer) or tests are shuffled

Root Cause

The original code only checked if RandomSequencer was being used, but RandomSequencer is only set when shuffle.files is true. When only shuffle.tests is true, BaseSequencer is used but the seed is still needed for shuffling tests.

Testing

Verified the fix with the reproduction from the issue
Ran existing sequencer tests (all pass)
The random.test.ts test was already flaky before this change (unrelated issue)

Previously, the seed was only logged when RandomSequencer was used (i.e., when files were shuffled). This fix ensures the seed is also set and logged when only test shuffling is enabled, since the seed is used for shuffling tests within files. Fixes vitest-dev#9557

Thank you for your contribution. We should add a test confirming the seed is shown. You can see examples in test/cli. Prefer runInlineTests

Added tests using runInlineTests in test/cli/test/seed-logging.test.ts:

Seed is shown when sequence.shuffle.tests is true
Seed is shown when sequence.shuffle.files is true
Seed is shown when both shuffle options are enabled

Keep `sequence.seed` resolved unconditionally at the root, but restore `getSeed(): number | null` returning null unless files or tests run at random (in the root config or any project). This keeps the documented "seed iff random" semantics (vitest-dev#8592, vitest-dev#9576) while sharing one seed across projects. The logger banner now reuses `getSeed()` instead of duplicating the check. Co-authored-by: OpenCode (claude-opus-4-8) <noreply@opencode.ai>
