From 07aa7f1de0ae1d31533c7824ecb63fc85a06be9f Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 26 Jan 2026 18:20:43 +0000 Subject: [PATCH 1/6] test: add tests for timestampOutputFormat/useInt64Timestamp defaults Add 7 new system test cases to `system-test/timestamp_output_format.ts` to verify the behavior of `Table.getRows` when `formatOptions.timestampOutputFormat` or `formatOptions.useInt64Timestamp` are omitted. These tests confirm that `useInt64Timestamp` defaults to `true`, causing conflicts with incompatible formats like `FLOAT64` unless explicitly disabled. --- system-test/timestamp_output_format.ts | 63 ++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) diff --git a/system-test/timestamp_output_format.ts b/system-test/timestamp_output_format.ts index a8f2c2b6..8befb3fe 100644 --- a/system-test/timestamp_output_format.ts +++ b/system-test/timestamp_output_format.ts @@ -133,4 +133,67 @@ describe.only('Timestamp Output Format System Tests', () => { assert.strictEqual((e as Error).message, 'Cannot convert 2023-01-01T12:00:00.123456789123Z to a BigInt');
