What Is Localization Testing?

Updated: Apr 30, 2022

Good communication is the key to any relationship including the relationship with your customers and stakeholders. As apps go global, it is vital to ensure that app quality is maintained across multiple platforms, browsers, and locations.

In this blog post, we will learn about the different aspects of localization testing and its importance in marketing.

Localization testing is one of the least understood areas of the software localization process. It is one of the key parts of the software and website localization process. It takes place when a piece of software or website is being localized for use in a new language or region. Local engineers and translators help to localize software. Let’s find out different aspects of this topic in detail.

Performing your research vs. Localization services


In research, you can find out for yourself what need to do and have an in-house localization tester and localization testing tools. Researching how to test the localization version and testing in-house may prove a more cost-effective action than using a professional localization agency.

A lack of in-house understanding and experience can end up leading to wasted time during the localization testing process.

Localization services

An alternative option is to use professional localization services for a better understanding of the localization testing process for you. A decent localization service will be able to provide experienced localization testers who can undertake to test quickly and efficiently. While using professional testers can save your money on localization testing tools, you still need to pay the localization agency for the work it undertakes.

Localization is based on the results obtained from globalization testing, which verifies the functional support for that particular culture. It can be executed only o the localized version of the product.

Steps in localization testing

The process of localization testing involves several steps:

  • Define and study a list of supported languages

  • Verification of user interface translation

  • Check of translation of system messages and errors

  • Check translation of help and accompanying documentation

  • Check of translation in the context of the subject matter of this product.

The test effort during localization testing focuses on areas affected by localization such as AUI and content and also culture-specific, language-specific, and region-specific sites. Besides, localization should include basic functionality testing, setup and upgrade tests running in the localized surrounding, and planning application and hardware compatibility tests.

Advantages of localization testing:

  • It reduces the cost of testing.

  • It helps in time management by reducing time for testing.

  • It has more flexibility and scalability.

Disadvantages of localization testing:

  • This process may require the hiring of local transporter that increases its cost.

  • A fully trained personnel and domain expert is required.

Localization majorly affects areas such as content and UI. It is done to ensure that product behaves according to its settings or not.
