From 08e823d6ab4faae74818ac3233efe12f5fd368fd Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Sun, 8 Feb 2026 11:03:50 -0500 Subject: [PATCH] test: add comprehensive test suite for normalization functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add 100+ test cases covering all normalization scenarios: - Empty/nil inputs, whitespace trimming - Titlecasing with hyphens, apostrophes, multi-word tags - Punctuation preference (hyphens, periods, apostrophes) - Case-insensitive deduplication with and without punctuation - Contributor case preservation (CAPSLOCK, Title Case, lowercase) - Edge cases: only punctuation, multiple spaces, mixed content New test scenarios for punctuation preference: - Prefer "Science-Fiction" over "science fiction" - Prefer "O'Reilly Media" over "OReilly Media" - Prefer "ACME CORP." over "acme corp" - Test deduplication when punctuated version appears later in array All tests passing ✓ Relates to Tags & Contributors Migration Phase 4 --- internal/utils/tags_test.go | 518 ++++++++++++++++++++++++++++++++++++ 1 file changed, 518 insertions(+) create mode 100644 internal/utils/tags_test.go diff --git a/internal/utils/tags_test.go b/internal/utils/tags_test.go new file mode 100644 index 0000000..75cbd71 --- /dev/null +++ b/internal/utils/tags_test.go @@ -0,0 +1,518 @@ +package utils + +import ( + "testing" + + "github.com/stretchr/testify/assert" +) + +// TestNormalizeTags tests tag display normalization +func TestNormalizeTags(t *testing.T) { + tests := []struct { + name string + input []string + expected []string + }{ + { + name: "empty array", + input: []string{}, + expected: []string{}, + }, + { + name: "nil input", + input: nil, + expected: []string{}, + }, + { + name: "single tag", + input: []string{" science fiction "}, + expected: []string{"Science Fiction"}, + }, + { + name: "multiple tags", + input: []string{"fiction", "adventure"}, + expected: []string{"Fiction", "Adventure"}, + }, + { + name: "multi-word tag", + input: []string{" science fiction "}, + expected: []string{"Science Fiction"}, + }, + { + name: "hyphenated tag", + input: []string{"non-fiction"}, + expected: []string{"Non-Fiction"}, + }, + { + name: "mixed case", + input: []string{"FICTION", "fiction", "Fiction"}, + expected: []string{"Fiction"}, + }, + { + name: "case-insensitive dedup", + input: []string{"fiction", "FICTION", "Fiction"}, + expected: []string{"Fiction"}, + }, + { + name: "remove empty strings", + input: []string{"fiction", "", "adventure", " "}, + expected: []string{"Fiction", "Adventure"}, + }, + { + name: "whitespace trimming", + input: []string{" fiction ", "\tadventure\t"}, + expected: []string{"Fiction", "Adventure"}, + }, + { + name: "preserves punctuation", + input: []string{"science-fiction", "O'Reilly"}, + expected: []string{"Science-Fiction", "O'Reilly"}, + }, + { + name: "complex real-world example", + input: []string{" science fiction ", "FICTION", "non-fiction", "", " "}, + expected: []string{"Science Fiction", "Fiction", "Non-Fiction"}, + }, + { + name: "prefer punctuation -
