Imagine launching your cutting-edge app, only to see it falter in a key international market due to unreadable characters or culturally insensitive visuals. Frustrating, right? Now, every tech company dreams of becoming a global fan favorite.

While a big part of this is having a top-notch software product, it also demands understanding and meeting the unique expectations of users across diverse geographies.

You see, many regions prefer to use software in their local language. For instance, South Koreans or the French often prefer interfaces and content fully adapted to their cultural and linguistic preferences.

Managing all of that can be a real challenge.

Luckily, that’s exactly what globalization testing is designed to do. In this blog post, we’ll discuss how it works, including its types and key elements and what to consider when testing your software for global compatibility.

But first, let’s start with the basics.

What is Globalization Testing?

Simply put, it’s the process of checking whether an app or website delivers a customized experience to global users while maintaining consistent quality. It evaluates elements like currency, local time, and language to ensure they adapt seamlessly to the user’s region.

It’s essential to understand the difference between globalization and localization testing:

Localization testing is a subset of globalization testing that ensures the app’s performance is attuned to a specific location or culture. However, globalization testing focuses on the app’s adaptability to various locations and cultures.

Types of Globalization Testing 

To ensure comprehensive global readiness, your testing process should include:

  • Localization testing: This identifies region-specific formatting expectations, cultural nuances, and user preferences and aligns the software with these factors. It tests with a focus group to ensure users in the targeted region feel entirely comfortable using it.
  • Internationalization testing: This assesses the software’s ability to support different languages, configurations, text alignments, and character sets without compromising functionality or data integrity.
  • Linguistic testing: This involves working with native-speaking linguistic testers to review the software for readability, cultural sensitivity, consistent terminology, and suitability for different contexts.

Importance of Globalization Testing

Today, tech companies everywhere are opting to expand to international markets, meaning their products must be ready to cater to different types of users in different regions without major code changes. 

Globalization testing ensures that an application is ready to function appropriately across multiple linguistic and cultural settings by catching any bugs early on.

This not only creates a smooth user experience (by avoiding errors like faulty characters being displayed or incorrect date formats) but also boosts the brand’s reputation in the regions being targeted.

Moreover, different countries have their own digital compliance standards that any software with a presence in the country needs to adhere to (e.g., GDPR in Europe). Globalization testing ensures that the software is designed to meet those requirements.

Key Elements of Globalization Testing 

Multiple elements must be considered during globalization testing to ensure that your software product is ready for global markets.

1. Date, time, and currency formats

First, it must correctly display dates, times, currencies, and units of measure in the local formats. The U.S., for instance, displays dates as MM/DD/YYYY instead of DD/MM/YYYY, which is the preferred format for many Asian and European countries.

In addition, ensure currency symbols and decimal separators are handled correctly—for example, $1,000.50 in the U.S. vs. €1.000,50 in Europe.

2. Content nuances

Any foreign language needs to be rendered correctly, especially complex scripts like Chinese, Devanagari (used in Hindi), or Arabic. The tone of the language needs to be considered, too—some regions may prefer formal communications over informal ones.

For example, formal and polite language (Keigo) is often preferred in professional or business contexts in Japan. In contrast, in the U.S., a more casual tone might be acceptable and even expected in similar situations.

3. Symbol usage

Be mindful of cultural contexts and nuances with regard to the emojis, images, and colors you use. Emojis, in particular, may mean different things in different contexts, so do your research to ensure you don’t come across as negative or offensive.

4. Visual aesthetics

Different colors can also mean different things depending on which country you’re in—red, for instance, symbolizes prosperity in China but may be viewed as a “danger” or “stop” signal in other countries.

5. Sorting and collation

Lastly, ensure data sorting and collation in the app or website respects locale-specific rules. For example, sorting names alphabetically might differ depending on the language, such as how “ñ” is handled in Spanish.

It would help if you were also mindful of case sensitivity rules, which can vary—for example, in Turkish, uppercase “I” and lowercase “i” are treated as distinct characters.

How to Perform Globalization Testing on Real Browsers and Devices

Typically, QA teams will follow these steps to ensure that they can accurately test their software in diverse contexts.

1. Pick the right automation tool

Manual globalization tests are highly time-consuming, so an automation tool is the best way to see how your app or website behaves with end users. It gives you the experience of seeing how the user journey takes place on test real browsers and devices, including potential hurdles as they navigate.

You can also test for situations like low battery, unstable network connections, or transitions between network zones. Choose a tool based on market reviews, suitability for your industry, ease of use, and budget.

2. Choose a team of human testers

Human testers remain indispensable to the process, even if automation tools handle the testing at scale. Choose those adept at crafting test scripts, supervising the testing, analyzing the results, applying their intuition, and making final decisions about software quality. 

3. Decide which elements to test

Work with your team to identify which UI elements make a core difference to users across different regions. Typically, GUI testing will include language, currency display, date and time format, address format, vocabulary nuances, and so on—basically, everything we’ve covered in this blog so far.

4. Write and run test scripts

Based on the elements and scenarios you choose to test, write suitable automation scripts for each. Then, feed the tests into your automation tool and have them run each. You can use CoTester to create test scripts without the need for extensive coding knowledge.

It helps you do so by analyzing your app’s workflows and requirements. You can customize these scripts to match specific testing needs, ensuring thorough coverage. It can detect bugs and performance issues before and after deployment, pass those bugs to the team, and get them fixed.

5. Study the results

Have your human testers examine the results provided by the automation testing tool to understand what problems cropped up and where. Then, send appropriate reports to the dev team so they can make the necessary fixes.

Common Challenges in Globalization Testing 

Every region and culture has its own requirements and preferences regarding the software it uses. While tuning your software to meet those needs is a key part of gaining international recognition, there are several difficulties with doing so effectively.

  • For instance, adapting the text to support multiple languages can be time-consuming. You’ll need to test for dynamic space expansion and right-to-left UI adaption to support different languages, as well as text alignment and navigation flows.
  • Geolocation testing for consistency across devices, browsers, and operating systems is also key—especially in regions that use proprietary or region-specific systems instead of common ones like iOS or Android
  • Typically, adapting your software to suit different languages will involve collaborations with translators and cultural consultants, which will require you to maintain up-to-date records of translations and region-specific nuances and keep adapting the software on the go.
  • Finally, remember to test time-sensitive features like alarms, calendar reminders, and scheduled notifications in the user’s local time zone.

Frequently Asked Questions (FAQs)

1. Why is Unicode support critical in globalization testing?

Unicode is a universal character encoding standard that ensures consistent text representation across platforms and languages. Without Unicode support, some characters might display incorrectly or cause errors in data processing.

2. How do you handle text expansion during globalization testing?

Some languages require more space than others to convey the same message, particularly for character-heavy scripts. For example, German sentences can be 30–40% longer than English. Test dynamic UI layouts, including buttons, labels, and text fields, to ensure they accommodate longer strings without truncation, overlap, or distortion.

3. How do you test for Right-to-Left (RTL) languages?

Key steps for testing RTL languages like Arabic or Hebrew include:

  • Ensuring UI mirroring works correctly (e.g., menus shift to the right)
  • Verifying text alignment, navigation flows, and direction-sensitive elements
  • Evaluating bidirectional content scenarios (e.g., RTL languages with embedded LTR text like numbers or URLs)
  • Checking compatibility across different browsers and devices

4. What is pseudo-localization, and why is it important?

Pseudo-localization is a testing technique that replaces text with pseudo-strings (e.g., “Hèllö Wörld!”) to simulate different languages, including text expansion and special character rendering. It helps identify issues like text truncation, encoding problems, or hard-coded strings before actual localization begins.

5. How do you address SEO for globalized websites?

Please ensure your site incorporates regional-specific keywords in translations, including testing for localized URLs and metadata. A good globalization testing example would be verifying that hreflang tags are correctly implemented and that the regional URLs resolve properly for different locations.
