From c9e782030a768da471616d626096eb325e12c38c Mon Sep 17 00:00:00 2001 From: Georgii Gorbachev Date: Wed, 20 Nov 2024 22:12:02 +0100 Subject: [PATCH] [Security Solution] Fix flaky test for multiline diff algorithm (#201019) **Fixes: https://github.com/elastic/kibana/issues/201014** **Related to:** https://github.com/elastic/kibana/pull/199388 ## Summary This PR increases the threshold (time limit) value for the test by 2x from 500 ms to 1000 ms. Hope it should be enough to eliminate flakiness on CI. --- .../algorithms/multi_line_string_diff_algorithm.test.ts | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/x-pack/plugins/security_solution/server/lib/detection_engine/prebuilt_rules/logic/diff/calculation/algorithms/multi_line_string_diff_algorithm.test.ts b/x-pack/plugins/security_solution/server/lib/detection_engine/prebuilt_rules/logic/diff/calculation/algorithms/multi_line_string_diff_algorithm.test.ts index 72e87fde6ca2f..8f0b3586066fa 100644 --- a/x-pack/plugins/security_solution/server/lib/detection_engine/prebuilt_rules/logic/diff/calculation/algorithms/multi_line_string_diff_algorithm.test.ts +++ b/x-pack/plugins/security_solution/server/lib/detection_engine/prebuilt_rules/logic/diff/calculation/algorithms/multi_line_string_diff_algorithm.test.ts @@ -174,9 +174,11 @@ describe('multiLineStringDiffAlgorithm', () => { const result = multiLineStringDiffAlgorithm(mockVersions); const endTime = performance.now(); - // If the regex merge in this function takes over 500ms, this test fails + // If the regex merge in this function takes over 1 sec, this test fails // Performance measurements: https://github.com/elastic/kibana/pull/199388 - expect(endTime - startTime).toBeLessThan(500); + // NOTE: despite the fact that this test runs in ~50ms locally, on CI it + // runs slower and can be flaky even with a 500ms threshold. + expect(endTime - startTime).toBeLessThan(1000); expect(result).toEqual( expect.objectContaining({
