How Crucial is Localization Testing in Software Testing?

Establishing a world-class business is never an easy task, let alone expanding to a neighborhood country. Because each region comes with a different set of habitats, languages, ideologies, and standards, even their customer-centric perspective could be different. But it isn’t impossible if you integrate localization testing in software testing because it can steadily improve your service flexibility and consistency while creating scope to generate a greater source of income.

So, let us see what localization testing has to offer in this blog!

How can localization testing be defined?

Localization testing in software testing is a popular method to verify that the application fits the local environment or region. It tests the proper translation of data, usage of correct symbols, and compliance with regional regulations. In other words, it’s customizing an application based on the targeted audience’s language, preferences, and standards.

In truth, this particular test process is a crucial element in estimating the success or maybe failure of an application in a certain regional market. Thus, developers must particularly focus on the way the content, functionality, UI, and enhancement of app programs appear in several places. Additionally, localization is primarily created for software, websites, E-learning platforms, games, etc.

In the following section, explore the significance of localization testing in software testing in detail.

Why are localization tests crucial in software testing?

Localization supports the "one country, one culture, one language" slogan. That suggests it is not important to master English for browsing. Readers can comfortably replace the settings as per their region preferences for much better use. So today, let's see many more benefits of localization testing in software testing:

1.    Enhanced user experience

Localization testing in software testing guarantees the application is well-adjusted to the local regulations and language demands. Thus, it emphasizes a good user experience by changing to various time zones, time formats, and accurate translation.

2.    International market reach

By localizing, you can expand your service venture beyond your country's origins. At the same time, you can target international markets and foreign customers for reach. Furthermore, developing such an interface increases the overall growth potential.

3.    Compliance with local standards

Localization testing in software testing also ensures that your software abides by different visual and content regulations for different regions. For example, healthcare apps and websites must follow regional compliance while giving out drug or medicinal-related information.

4.    Reduced costs

If you use localization testing tools from the beginning of the project, you can complete the overall testing for less time and money. And even avoid support costs like repairs, bug fixing, modifications, or updates for a long time.

5.    Scalability

Unlocalized apps frustrate consumers in other regions due to unfamiliarity with features. For example, the date format in Asian countries and Europe is different. Thus, localization testing helps to include familiar terms and formats of their culture.

In the next section, unravel the important features of localization testing services.

What components make up the localization tests checklist?

A checklist helps you to calculate the adaptability of merchandise to the target audience and market. Consequently, we have ready all the essential elements required for proper localization testing in software testing:

1.    Language

This very first component verifies whether text labels & messages are adequately converted into particular words or perhaps not. Additionally, search for text spacing issues because of language differences. Finally, check out the screen of emojis & text scripts on the unit.

2.    Currency format and measurement units

Second on our list of localization testing in software testing is the validation of the currency symbols, decimal points, and rate of conversion on the local currency format. On the flip side, check out the units of measurement, etc., imperial, like weights, in sync with the target area.

3.    Time and calendar systems

Date and time formats vary for various countries in localization testing and software testing. Thus, verify the appropriate time structure for the locale and include the essential time zones. Additionally, check for particular calendar systems, if any, widely used in the area.

4.    Legal rules

The region-specific settings you have created should comply with the compliance regulations. For that reason, adding a local research team or SME to the regional laws on information privacy and safety requirements is safer.

5.    UI/UX and UAT

The product in localization testing in software testing needs to align with local user expectations. Thus, completely examine the UI layout and graphics on the culturally appropriate standards. Additionally, use user acceptance testing to collect responses for improvement.

These are only a few. There is a lot more to see. So, let’s see the step-by-step procedure to perform localization tests in the next section.

How can you perform localization tests in software testing?

Localization testing in software testing is a repeated process; therefore, performing it many times is essential to achieve efficiency and high quality for the item. If so, select suitable localization assessment programs and stick to these steps:

1.    Define product needs

To start with, understand your project requirements for localization, languages, local culture, including audience, and compliance demands. They will allow you to outline the localized palette required for any application program to reach the indigenous market.

2.    Build your team

Try to blend in experienced designers combined with native speakers of the language alongside engineers. Moreover, to promote interpretation in the application program, it's recommended to have subject matter experts and translators on board.

3.    Create a test plan and strategy

A comprehensive test program is a structure for the project. So, meticulously produce the plan, like the scope of evaluating, etc., content and features, that will be your guide to managing workflow. Additionally, pick a good testing strategy to enhance the process.

4.    Set up the test environment

Prepare test locations depending on the target market conditions. Additionally, adapt your devices, browsers, and operating systems to match the local necessities. In effect, employ localization testing tools with automation to mimic the circumstances and improve testing.

5.    Implement translation

This particular stage is crucial, as we imply translation to transform all text content material inside the program. Hence, collaborating with indigenous speakers for cultural and language input will aid you in customizing your functions into reality.

6.    Perform functional testing

Evaluate your software performance to determine if it is effective as intended in the localized version or perhaps not. Meanwhile, double-check several factors such as usability, regression, and compatibility of your project with region-specific needs.

7.    Content validation

After functionality testing, confirm the translated text for troubles in UI elements. Ensure that all text is displayed properly, including RTL nature. Further, validate features are contextual.

8.    Analyze reports and retest

Lastly, examine all your documented data as a test program, font style, and instructions. Next, iterate tests until you achieve your goals and provide a detailed summary to stakeholders about the funds, test coverage, and challenges faced.

Possible challenges & solutions of localization testing

Following are some of the challenges to look for when performing localization testing in software testing. Also, along with them, there are solutions so that you can instantly implement the changes without wasting any further moments:

1.    Language barriers

Testers should be proficient or native in the area language to look at the program. Or else it is tough for them to create such complicated software. This problem could be fixed very easily by arranging language training courses for non-native speakers.

2.    Different technologies

In truth, converting to various other devices and operating systems of the overseas market is quite costly, rough, and resource-consuming. Therefore, it is better to partner with local QA services to ensure the same process with reduced cost and high quality.

3.    Lack of automation

Many localization testing services haven’t adopted AI-based technology and tools. So, it leaves a high chance for human errors and decreasing quality. Therefore, it’s better to consider local companies that use automation for testing without human intervention.

4.    Expensive experts

The domain and language experts for many regions might be expensive. Hence, outsourcing the localization testing in software testing within your budget means all of the staff requirements and applications will be supplied by them.


Localization testing in software testing is the most recent work culture for developing apps. From MNCs to small start-ups, everyone can use several platforms, such as smartphones and browsers, to broaden beyond horizons. Hence, do not view it as a single opportunity to make a bigger pool of revenue, but find out how globalizing your venture could ultimately help you.
