From 2fcfd8a29931dec065ff113e153837d1d05e172e Mon Sep 17 00:00:00 2001 From: 0xYYBB | ZYY | Bobo <128128010+the-dev-z@users.noreply.github.com> Date: Tue, 11 Nov 2025 09:30:03 +0800 Subject: [PATCH] =?UTF-8?q?fix(web):=20display=20'=E2=80=94'=20for=20missi?= =?UTF-8?q?ng=20data=20instead=20of=20NaN%=20or=200%=20(#678)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(web): display '—' for missing data instead of NaN% or 0% (#633) - Add hasValidData validation for null/undefined/NaN - Display '—' for invalid trader.total_pnl_pct - Only show gap calculations when both values are valid - Prevents misleading users with 0% when data is missing Fixes #633 * test(web): add comprehensive unit tests for CompetitionPage NaN handling - Test data validation logic (null/undefined/NaN detection) - Test gap calculation with valid and invalid data - Test display formatting (shows '—' instead of 'NaN%') - Test leading/trailing message display conditions - Test edge cases (Infinity, very small/large numbers) All 25 test cases passed, covering: 1. hasValidData check (7 cases): valid/null/undefined/NaN/zero/negative 2. gap calculation (3 cases): valid data, invalid data, negative gap 3. display formatting (6 cases): positive/negative/null/undefined/NaN/zero 4. leading/trailing messages (5 cases): conditional display logic 5. edge cases (4 cases): Infinity, -Infinity, very small/large numbers Related to PR #678 - ensures missing data displays as '—' instead of 'NaN%'. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: tinkle-community --------- Co-authored-by: ZhouYongyou <128128010+zhouyongyou@users.noreply.github.com> Co-authored-by: tinkle-community --- web/src/components/CompetitionPage.test.tsx | 329 ++++++++++++++++++++ web/src/components/CompetitionPage.tsx | 30 +- 2 files changed, 354 insertions(+), 5 deletions(-) create mode 100644 web/src/components/CompetitionPage.test.tsx diff --git a/web/src/components/CompetitionPage.test.tsx b/web/src/components/CompetitionPage.test.tsx new file mode 100644 index 00000000..6b06139d --- /dev/null +++ b/web/src/components/CompetitionPage.test.tsx @@ -0,0 +1,329 @@ +import { describe, it, expect } from 'vitest' + +/** + * PR #678 測試: 修復 CompetitionPage 中 NaN 和缺失數據的顯示問題 + * + * 問題：當 total_pnl_pct 為 null/undefined/NaN 時，會顯示 "NaN%" 或 "0.00%" + * 修復：檢查數據有效性，顯示 "—" 表示缺失數據 + */ + +describe('CompetitionPage -
