From 26033be84dace8a9af77f48199498708023d4d87 Mon Sep 17 00:00:00 2001 From: Mo Kweon Date: Thu, 2 Oct 2025 00:02:26 -0700 Subject: [PATCH 1/6] test: improve floating-point comparisons for cross-platform stability Floating-point values can have slight precision differences across different architectures, compilers, and optimization levels, causing tests to fail intermittently on different systems. - Replace exact equality checks with tolerance-based comparisons using go-cmp library with 0.001 delta for float32/float64 values - Update example test to use formatted output (%.2f) instead of raw float printing to ensure consistent behavior across platforms - Maintain test accuracy while eliminating architecture-dependent test failures This ensures tests pass reliably on ARM, x86, and other architectures regardless of floating-point representation differences. --- go.mod | 9 +++++++-- go.sum | 2 ++ kiwi_example_test.go | 4 ++-- kiwi_test.go | 41 +++++++++++++++++++++++++++-------------- 4 files changed, 38 insertions(+), 18 deletions(-) diff --git a/go.mod b/go.mod index 31ab263..44fe0ab 100644 --- a/go.mod +++ b/go.mod @@ -1,8 +1,13 @@ module github.com/codingpot/kiwigo -go 1.17 +go 1.21 -require github.com/stretchr/testify v1.7.0 +toolchain go1.23.0 + +require ( + github.com/google/go-cmp v0.7.0 + github.com/stretchr/testify v1.7.0 +) require ( github.com/davecgh/go-spew v1.1.0 // indirect diff --git a/go.sum b/go.sum index acb88a4..4c87ed3 100644 --- a/go.sum +++ b/go.sum @@ -1,5 +1,7 @@ github.com/davecgh/go-spew v1.1.0 h1:ZDRjVQ15GmhC3fiQ8ni8+OwkZQO4DARzQgrnXU1Liz8= github.com/davecgh/go-spew v1.1.0/go.mod h1:J7Y8YcW2NihsgmVo/mv3lAwl/skON4iLHjSsI+c5H38= +github.com/google/go-cmp v0.7.0 h1:wk8382ETsv4JYUZwIsn6YpYiWiBsYLSJiTsyBybVuN8= +github.com/google/go-cmp v0.7.0/go.mod h1:pXiqmnSA92OHEEa9HXL2W4E7lf9JzCmGVUdgjX3N/iU= github.com/pmezard/go-difflib v1.0.0 h1:4DBwDE0NGyQoBHbLQYPwSUPoCMWR5BEzIk/f1lZbAQM= github.com/pmezard/go-difflib v1.0.0/go.mod h1:iKH77koFhYxTK1pcRnkKkqfTogsbg7gZNVY4sRDYZ/4= github.com/stretchr/objx v0.1.0/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= diff --git a/kiwi_example_test.go b/kiwi_example_test.go index 8ae0b74..25e077a 100644 --- a/kiwi_example_test.go +++ b/kiwi_example_test.go @@ -14,7 +14,7 @@ func Example() { defer k.Close() // don't forget to Close()! results, _ := k.Analyze("안녕하세요 코딩냄비입니다. 부글부글.", 1 /*=topN*/, kiwi.KIWI_MATCH_ALL) -
