Bun test explicit test timeout third argument overrides --timeout CLI default timeout

💡 Result:

Yes, an explicit per-test timeout provided as the third argument to the test function overrides the --timeout CLI flag [1][2][3]. In Bun, while the --timeout CLI option (or the test configuration in bunfig.toml) sets a global default timeout for all tests [1][4][5], you can specify a unique timeout for an individual test by passing a number (in milliseconds) as the third argument to the test function [1][3]. This per-test setting takes precedence over the global default [3]. Example: test("custom timeout test", async => { // This test will have a 10-second timeout, // even if --timeout was set to a different value via CLI await doSomethingSlow; }, 10000);

Citations:

Raise the Linux batch timeout for tests/shutdown-launcher.test.ts.

The test at lines 121–150 allows 90 seconds for startup, 15 seconds for launcher exit, and 10 seconds for port cleanup. Its explicit 130-second timeout overrides Bun’s 60-second default. However, scripts/ci/run-bun-test-batches.sh:6,112-114 terminates each Linux batch after 120 seconds, so a slow run can be killed before completion and cleanup.

Set BUN_TEST_BATCH_TIMEOUT_SECONDS above 130 seconds, or run this test in a dedicated batch.

batch timeout configured by scripts/ci/run-bun-test-batches.sh so it exceeds the
130-second shutdown-launcher test duration, ensuring the test can finish its
startup, exit, and cleanup phases before the batch is terminated.
