Mohr notes, “Localization testing, There are ten characters between the letters L and n, thus this notation is also used. Pin code, data, phone number, currency, and other formats can all be tested for localization with the help of localization. Internationalization (i18n) is the process of making software compatible with several languages and cultures. Finding design flaws in applications that can prevent them from being used internationally. I18n testing ensures the product works as intended by simulating all conceivable international user input. It guarantees that the code can support all languages without breaking.”

Singhe says, “Globalization testing is the process of ensuring that a product operates as expected in multiple locations, languages, and cultures. It is different from localization testing which focuses on adapting the product to a specific language and culture. Globalization testing ensures that the product is capable of functioning in multiple cultures, while localization testing ensures that it is tailored to the needs of a specific culture. To summarize, globalization and localization testing are essential components of the software development lifecycle. By leveraging the right resources and technologies, companies can make sure that their products are accessible to a global audience, culturally appropriate, and relevant to their target markets.
