Frequently Asked Questions about localization-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test internationalization and localization across multiple languages and locales?▼

Localization testing verifies that multi-language products work correctly across locales by checking translation coverage, date/time/currency/number formatting, RTL layouts, and Unicode encoding. Run automated tests across your supported languages to identify gaps in externalization, missing translations, and locale-specific behavior before release.

What does RTL testing cover and why is it important for localization?▼

RTL (right-to-left) testing validates layout, text direction, and UI alignment for languages like Arabic and Hebrew. Proper RTL support ensures buttons, forms, and content flow correctly in RTL languages, preventing broken layouts and ensuring cultural appropriateness across markets.

How do I verify that all user-facing strings are properly translated and formatted?▼

Translation coverage validation checks that all strings are externalized, translated for each locale, and properly formatted according to locale-specific rules for dates, currency, and numbers. Automated testing identifies missing translations and placeholder issues before users encounter them.

When should I run localization testing during product development?▼

Run localization testing when launching in new markets, adding language support, before international releases, and after UI changes. Testing at these stages catches formatting errors, encoding issues, and missing translations early, reducing post-launch rework.

Does localization testing support Unicode character validation?▼

Yes, Unicode encoding checks ensure that special characters, accented letters, and non-Latin scripts display correctly across all locales. This prevents garbled text and ensures proper rendering of culturally-specific characters in your product.
