What is Localization Testing?
Localization Testing is the process of verifying a product’s adaptation for a specific region, language, or culture. It ensures translations, layouts, formats, and content meet local requirements.
Objectives of Localization Testing
- Ensure correct translation and language usage
- Verify regional settings, currency, date, and number formats
- Check UI layout for different text lengths and fonts
Advantages
- Improves user experience for target locale
- Ensures cultural appropriateness
- Reduces risk of misinterpretation or errors in local markets
Limitations
- Time-consuming for multiple locales
- Requires local language experts
- May need extensive test data for each locale
Localization Testing Process
- Identify supported locales and languages
- Prepare test cases for translation, UI, and formats
- Test translations and local settings

- Report issues and fix before release
️ Example
Example: A mobile app displays prices in USD for US users and in INR for India, and all buttons and text appear correctly in the local language.
