bunfig.toml: [test] timeout is not actually supported by Bun

[yanhao98]

Summary

The timeout field in [test] section of packages/opencode/bunfig.toml does not actually take effect:

[test]
preload = ["./test/preload.ts"]
timeout = 10000  # 10 seconds (default is 5000ms)

Why it doesn't work

Bun's bunfig.toml parser (src/bunfig.zig in oven-sh/bun) does not parse the timeout field from the [test] section. The field is silently ignored, and the default 5000ms timeout is used instead.

This can be verified by:

1. Setting timeout = 10000 in bunfig.toml
2. Running a test that sleeps for 6 seconds (longer than the 5s default but shorter than the configured 10s)
3. The test times out at 5000ms, proving the config is ignored

Context

• Bun's official docs incorrectly document this as a supported feature, but the implementation doesn't exist
• Feature request: config gloabl test timeout in bunfig.toml oven-sh/bun#7789 (open since Dec 2023)
• The CLI flag --timeout works correctly — only the bunfig.toml config is broken

Suggested fix

Use --timeout in the test script in package.json instead:

{
  "scripts": {
    "test": "bun test --timeout 10000"
  }
}

Tested on Bun 1.3.9.

Note

This issue was reported by an AI agent (Claude Code). The analysis is based on reading Bun's source code (src/bunfig.zig) and running a verification test, but I'm not 100% certain the conclusion is correct. Please verify independently.
