Application Testing Software: How to Test Software in Different Languages

onpathtesting_foreign-language-guides

Have you ever had to perform software testing on a website or mobile application written in a language you don’t understand? This challenge is common in global projects. Fortunately, many testers face the same situation, and proven application testing software practices can help ensure accuracy and usability across languages.

Understanding how to test multilingual applications when you don’t know the language starts with focusing on structure, layout, and behavior rather than translation alone.

Things to Check for When Testing Projects in Different Languages

When using application quality testing tools for multilingual projects, begin with visual and functional checks.

First, study the User Interface (UI) workflow of the website or application. Look for overlapping text, layout inconsistencies, alignment issues, and formatting errors. These issues often appear when text expands or contracts in different languages.

Next, test each input field by entering text in the target language. Include characters with accents, symbols, or diacritic marks to ensure the system handles them correctly.

After that, review menu items, button labels, and navigation elements. Confirm they display fully and remain readable. Also, check every hyperlink to ensure it leads to the correct destination.

In addition, search for leftover English words or phrases. Even small untranslated elements can disrupt the user experience.

While it helps to have Google Translate or a native speaker available, many websites and mobile applications follow similar UI patterns. Because of this consistency, QA tips for non-native language testing often emphasize understanding layout and behavior first.

Finally, always request a copy of the UI layout in English. This reference helps testers validate expected functionality without guessing intent.

How Web Analytics Supports Application Testing Software

Web analytics play a critical role in multilingual testing. Karen N. Johnson, Director of Mobile Quality for Orbitz, explains how analytics guide testing decisions when working with international applications.

How do I know what mobile devices are popular in other countries when I don’t see those devices or get exposure to them? I’ve learned to use web log analytics to see the trends and usage in different countries….I also use trending analytics from organizations like W3C to see overall trends across the globe. By looking at the trends in general and then reviewing the specific website statistics, I can see what’s in use and strategically align testing accordingly.

Using analytics alongside software validation platforms helps testers prioritize browsers, operating systems, and devices based on real usage data. This approach reduces guesswork and improves coverage.

For reference, tools and resources such as:

  • Google Analytics
  • W3C usage reports
  • Open-source analytics platforms

can provide valuable insights for global testing strategies.

Writing a Successful Multilingual Test Plan

Karen also outlines how analytics inform a strong test plan. When using application testing software, planning should align with real user behavior.

A test strategy factors in the distinct statistics of a site and adjusts to the user audience by gradually shifting testing efforts by browser, operating system and mobile devices as the audience shifts. Test planning is not just “interested” in the analytics; strategic planning is about using the analytics to map out what is needed, what is most at stake and then crafting a test plan that can be executed with that knowledge and awareness.

By combining analytics with risk analysis, testers can turn an overwhelming multilingual scope into a manageable and well-defined testing effort. This structured approach is central to how to test multilingual applications when you don’t know the language.

Jumping the Testing Hurdles of RTL and Vertical Languages

Testing multilingual applications introduces additional complexity. Karen highlights challenges related to right-to-left (RTL) and vertical languages.

The more widespread a user base, the more likely a website supports multiple languages. Languages introduce testing considerations like handling of right to left languages such as Arabic and Hebrew where testing ensures RTL handled correctly on text, lists and data entry fields.

She also explains that languages like Japanese and Chinese may shift testing focus toward UI alignment. Meanwhile, languages such as Romanian and Swedish require careful validation of diacritic marks in search, data export, and display.

Using application quality testing tools alongside targeted QA tips for non-native language testing ensures these language-specific challenges are handled accurately.

Final Thoughts on Multilingual Application Testing

Testing websites and mobile applications in multiple languages introduces many variables. However, by combining structured UI checks, analytics-driven planning, and the right application testing software, teams can confidently support global users—even without knowing every language involved.

Frequently Asked Questions (FAQs)

What is application testing software used for multilingual projects?

It helps validate functionality, layout, and usability across different languages and regions without relying solely on translation knowledge.

How can testers work on apps written in languages they don’t know?

They focus on UI behavior, layout consistency, analytics data, and structured test plans rather than language fluency.

Why are diacritic marks important in multilingual testing?

Incorrect handling of diacritics can cause display issues, search failures, and data corruption.

How do RTL languages affect application testing?

RTL languages require verification of text direction, alignment, lists, and data entry behavior.

What role do analytics play in multilingual testing?

Analytics reveal real-world device, browser, and OS usage, helping prioritize testing efforts.

Are native language testers always required?

They help, but structured QA tips for non-native language testing and strong software validation platforms can significantly reduce dependency.
