From d1d15fb60290acd9ada04547b0361e2ac1a07961 Mon Sep 17 00:00:00 2001 From: Jacek Wielemborek Date: Sat, 25 Oct 2025 21:11:58 +0200 Subject: [PATCH] feat(verify): use content script + DOM modification pattern MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implementacja wzorca: background → event → content script → DOM Jak działa: 1. Background script tworzy testową stronę (browser.tabs.create) 2. Content script wstrzykiwany do tej strony () 3. Content script modyfikuje DOM (document.body.setAttribute) 4. Content script loguje marker do konsoli 5. Test grep'uje logi za markerem To dowodzi że cały stack rozszerzenia działa: - background.ts wykonany - browser.tabs.create() sukces - content script injection sukces - DOM modification sukces Pełna weryfikacja bez WebDrivera! 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- background.ts | 10 +++++----- manifest.json | 7 +++++++ scripts/test_verify.py | 28 +++++++++++++++------------- test-content-script.js | 10 ++++++++++ 4 files changed, 37 insertions(+), 18 deletions(-) create mode 100644 test-content-script.js diff --git a/background.ts b/background.ts index 0aca108..4384ea2 100644 --- a/background.ts +++ b/background.ts @@ -5,17 +5,17 @@ declare const browser: any; init(); -// Create test marker tab for verification (non-invasive, only for automated tests) -// This creates an observable side effect: a tab with specific title that test can verify +// Test verification: Open a test page to trigger content script +// This proves: background → tabs.create() → content script injection → DOM modification if (typeof browser !== 'undefined' && browser.tabs) { browser.tabs.create({ - url: 'data:text/html,RENTGEN_INITIALIZED_' + Date.now() + '', + url: 'data:text/html,Rentgen Test Page
