localization-testing

This skill provides a comprehensive quality engineering framework for verifying the global readiness of software applications. It is designed for engineering teams, QA leads, and developers managing multi-language products who need to ensure that their interface remains functional and culturally appropriate across diverse regions. By automating the validation of string externalization, layout consistency, and locale-specific data rendering, it helps reduce the risk of UI breakage and user friction during international market launches.

• Automated translation coverage verification to ensure all strings are present across supported locales and missing placeholders are identified.

• Locale-specific format validation for dates, currencies, and numeric data to comply with regional standards like en-US vs. en-GB or ja-JP.

• RTL (Right-to-Left) layout analysis for languages such as Arabic and Hebrew, verifying that CSS directions, mirror images, and navigation elements flip correctly.

• Unicode character support testing to ensure stable rendering and storage for non-Latin scripts, including CJK characters and emojis.

• Hardcoded string detection that alerts developers to maintenance-heavy practices that hinder future translation efforts.

• Cultural appropriateness checks to validate icons, colors, and content-driven visual elements for regional sensitivity.

• Ideal for use during the CI/CD pipeline phase when adding new language support or refactoring UI components for global scalability.

• Integrates directly with browser automation tools such as Playwright or custom fleet scripts to perform visual regressions and dynamic content inspection.

• Expected outputs include detailed reports on translation gaps, format inconsistencies, RTL layout errors, and a log of detected hardcoded string identifiers.

• Ensure all user-facing strings are externalized into managed resource files (e.g., JSON/PO) before initiating testing to maximize scan accuracy.

• Operates best when coupled with visual testing skills for pixel-perfect RTL diffing and performance monitoring for localized latency issues.
