Test automation is crucial to enhance application testing effectiveness, broaden test coverage, accelerate execution speed, provide more accurate results, and deliver faster. It also helps testers to launch new features to market instantly and ensure a bug-free user experience.

But when the application is built for release globally or into a local market, it becomes challenging for developers to ensure that the application features including the content function as expected in the target market. For instance, when users download an app globally they expect it to work in their native language, with their native currency, and without acing any UI issues. Failing to test these things can lead to bad reviews or rejection of the app.

Therefore to provide a positive user experience that appeals to the target market’s local audience it is important to create applications that are relatable and flexible enough to take into account each user’s native language and culture as well as regional settings including currency, date, and time format. In this case, localization testing is required.

Localization testing plays a vital role in the application development life cycle as it ensures that the application’s features are locale-specific. This means when residents of the specific region open the website or app, they will see that the app user interface is rendering text, images, documents, currencies, keyboard usage, and the app’s content translated into local languages. In short, it ensures that the application is ready for use in that specific region.

Additionally, the test will also verify other factors such as default language settings, complying with local regulations, ad content, offers, date and time format, and documentation.

In this article, we will explore in detail what localization testing is, why it is important to perform, and what are its advantages and disadvantages. Lastly, we will see how the LambdaTest platform can help to enhance this testing technique.

Localization testing

Localization testing is a testing approach that verifies a website or app’s quality, content, UI, functionality, accuracy, and usability concerning specific locations, regions, default languages, culture, audience, currency, date and time format, preferences, and other requirements of a specific region. A specific region could be a particular city or an entire country.  

The purpose of localization testing is to ensure that the behavior of an application is appropriate for users in a specific target audience region.

It involves validating the globalized application’s functionality such as the correct translation of the text, the use of appropriate symbols, icons, colors, and characters, documentation, and compliance with area-based regulations and standards (country or state) as per the local environment.

Why perform localization testing?

It’s crucial to conduct this testing to ensure the application’s success and that it meets the needs and expectations of users in a specific regional market. It includes changes in the user interface or even in the initial settings according to the requirements.

This method of testing intends to analyze and validate how the application would behave globally to provide linguistic and cultural importance for different parts of the world. However it not only aims to ensure that the app or website works as expected but to serve a personalized user experience by offering features to individuals according to where they are and what they might prefer.

In this type of testing, different testers repeat the same functions to verify various aspects like typographical errors, cultural suitability of UI, linguistic errors, etc.

Advantages of localization testing

There are several advantages of Localized testing performed to test websites, apps, and interfaces for users in a specific region. Below are some of the advantages of performing this testing.

Avoiding misunderstandings

Misunderstandings or mistakes can arise when applications are not localized. For example, unfamiliar or incorrect date/time format can cause confusion and frustration for users, or language translation mistakes can harm its reputation and success.

Localizing an application can reduce the risk of mistakes, misunderstandings, and cultural insensitivity. An adequate localization testing process ensures that the application uses familiar formats and terminology, and catches mistakes early so they can be corrected before it is ready to release.

For example, if an application is originally developed for an English audience and after testing localization they found that a specific emojis used in the English version can have a different meaning in other languages, cultures, or country regions. Ignoring these minor details can have a severe impact; and harm the success of the application.

Increased market reach and more revenue

If users can read the content on the app, naturally they will not use it. Through localization testing it would be easier to identify the preferences of the users in specific regions, the user interface that they like and the functionalities that they prefer.  users get the tailored and localized experience that they are looking for.

Therefore, localizing an application helps to expand the market reach and target users in different regions by providing tailored and localized experiences that they are looking for. This can help to increase the user base and potential market share.

Competitive advantage and trust in global markets

If users don’t know the app they will not trust it or use it. Therefore designing the app for the international market helps to pay this off.  Localization testing gives a competitive advantage in the global market over competitors who do not offer localized applications in certain regions. 

Effective translation and localization can significantly grow the audience in new places. Localization testing is important because it provides an improved localized user experience and increases market reach globally.

For example, one country might prefer an app with a minimalistic design and another may prefer a more enhanced visually appealing app design. This information obtained from the localization testing technique, helps the app stand out from its competitors and thus gain more revenue.

Compliance with local regulations

Different regions have different regulations and standards that applications must adhere to. Localizing an application ensures that it complies with local laws and regulations in each target market, Localization testing helps to ensure that the application is compliant with local regulations, avoiding the risk of legal or regulatory issues.

Improved user experience

Localization testing ensures that users can navigate the application more effectively and easily in different regions, as it ensures that the localized application is adapted to their local language, cultural preferences, and regulatory requirements. As a result, this helps improve the user experience and increases user satisfaction with the application.

Disadvantages of Localization Testing

Despite the above advantages, localization testing has some disadvantages as well. They are-

  • Localizing application content and UI components to different languages, there are chances of potential bugs and errors that may creep in and affect the functionality and usability of an application for all users. Therefore translating and adapting content and UI elements to a different language requires attention to detail, to avoid any mistakes that may have damaging outcomes. Additionally, it requires hiring local translators to translate and adapt UI elements to different languages, which often makes the process costly.
  • Localization issues adequately require finding domain experts and assembling a dedicated testing team. this can be challenging, time-consuming, and costly.
  • Ensuring that the localized versions of the application provide consistency and seamless experience for users compared to the original version is essential. This requires testing regularly and carefully throughout the development process, which is quite challenging.
  • Balancing resources between developing new features and releasing localized counterparts, is not easy, as any arising issues can delay the release of the application as additional time is needed to resolve the issue. Therefore it is essential to use resources wisely by prioritizing the task of developing new features and the localization process to maintain efficiency throughout and minimize potential delay.
  • Maintaining the functionality after the application has been localized might be difficult. The application may need to be translated during updates and adapting the application to different languages and cultures during that period adds time and resources to the process.

Best practices for localization testing

To localize an application successfully testers need to know some of the best practices and implement them in their journey of testing localization.

Plan the testing strategy

Planning a test strategy means understanding the objective of this testing. That is what are the different cultures and languages the application should be tested on, which component of the application requires more focus, the system requirements, different operating systems testing should be performed on, a tool to be used, etc. Hence, these points should be clearly and carefully noted before starting localization testing.

Do not rush

A perfectly localized website or app is not an overnight result. It takes time to integrate the resources necessary to run these tests. Marketing teams also require sufficient time and capabilities to research their targeted audience which is different for each country, state, and city.

For successful optimization, teams must know about their target users’ preferences and need to tailor the application design test cases accordingly

Ensuring accurate translation also needs time, confirming that nothing is remotely offensive, or insensitive requires extremely keen sight to make it to the production stage, as well as it takes time to understand cultural differences, especially when the tester is not from that particular culture. In short, localization testing needs time and patience to perform.

Test early, and often

Localization testing should be incorporated into the application development lifecycle from the beginning. It is recommended not to wait to run these tests until after most development is finished, just right before pushing the application to production.

This is because translations, text arrangement, adding or keeping out services and other aspects of localization cannot be managed last-minute. Therefore it’s best to start testing as early as possible to avoid any costly and time-consuming changes later on in the process.

Consider automating localization testing

A better way to achieve the requisite mix of speed and accuracy in localizing an app is by combining manual testing with automation. Because for repetitive tasks automating tests as much as possible saves time, accuracy, and productivity of the team.

 Following these best practices will help ensure that the application is adapted to local requirements and meets the needs and expectations of users in different regions.

It verifies the quality of the application and checks whether it meets the cultural, linguistic, and other requirements of the users of the particular region or locale where it is to be launched, and provides a seamless experience.

However, localization testing is a complex process that must consider many factors and guidelines for delivering the application to a local market. It requires testing different language translations, date and time formats, currency and number formats, and other critical user interface components. This also involves testing the application across different operating systems, web browsers, and devices to ensure compatibility.

Additionally, it includes examining the application’s compliance with local laws and regulations, including data privacy laws, and cultural norms. All of this requires comprehensive testing which can only be achieved using automated testing tools like LambdaTest.
