How to Do Localization Testing & Advantages Explained

How to do localization testing” is often asked question by many testers. Localization testing is the crucial process of determining whether your newly localized software application or website can hold up to the cultural and usability standards of your target audience.

You're basically throwing a party for your software, but you want to make sure that your guests (your new audience) enjoy themselves and feel at home.

To ensure this, you need testers who will put your app through the wringer, assessing everything from the UI to the default language, to currency and time formats. It's like the quality assurance (QA) process of software development, but with the added challenge of cultural adaptation. The testers are like expert partygoers who can spot any areas where your app's localization didn't hit the mark. It's a critical step to make sure that your software is authentic and respectful in the eyes of your new audience. Without localization testing, you could be risking your software's reputation and even offend your new audience.

What Advantages Does Location Testing Have?

Location testing has many advantages, and here is a list of its most prominent advantages:

  • Identify and fix issues in different locations

Location testing allows developers to identify and fix any issues that may arise when the app is used in different geographic locations. For example, an app that relies on GPS functionality may have difficulty getting accurate location data in areas with poor satellite coverage. But developers can identify and fix these types of issues before the app is released to the public according to location testing.

  • Ensure the app is accessible to users

Developers can also ensure that if the app can be used by people no matter where they are located by using location testing. This can help to increase the number of people who will be able to use your app and therefore increase your app's user base.

  • Test app performance in various environments

And location testing help to ensure that the app works well in different types of environments and identifies any issues that may arise, such as connectivity issues in rural areas.

However, there are still some disadvantages of location testing here:

  • Time-consuming and resource-intensive

Testing the app in different locations can be time-consuming and resource-intensive, as it requires testers to physically go to different places and perform the testing.

  • Cannot simulate real-world conditions

It is not easy to simulate real-world conditions in a controlled testing environment, which means that some issues may only become apparent when the app is being used in the real world.

How to do localization testing?

Localization testing primarily focuses on three areas: language, user interface (UI), and user experience (UX). Testing should ensure that content loads correctly in the target language and that it does not negatively impact the overall user experience. And testers also need to check that the code works as intended, that placeholders match the correct strings, and that the correct fonts load for each language.

  • Steps to do localization testing:

When performing localization testing, start by creating a testing checklist or framework. This list should include all the relevant information, context, and variables related to the localization process. Providing as much information as possible to testers can lead to more thorough testing. Some essential steps to follow include:

  • Gather all relevant information about the product or website, including documentation, background information, and industry-specific terms that provide additional context.
  • Create a user guide for testers to follow, such as an ideal use scenario, to help them understand how customers will use the product or website.
  • Perform both guided and exploratory testing to ensure thorough testing.
  • Test for appearance and layout, functionality, cultural appropriateness, and the accuracy of the translation.

Differences between localization testing in software and websites:

While there is some overlap between localization testing for software and websites, they are different enough that knowing what to look for is essential. For example, testing the functionality of an app versus a website requires a different approach. Therefore, it's important to be familiar with the differences between localization testing for software and websites to conduct thorough testing.
