Basics of localization testing

Internationalization vs. localization

Internationalization (i18n) and localization (L10n) are two key steps in making software work for different languages and cultures.

Goals of localization testing

Localization testing checks if software works well in different languages and regions. Here are its main goals:

1. Check translations and formatting
2. Make sure content fits the local culture
3. Test if all features work correctly
4. Follow local rules and laws

Types of localization tests

There are several types of tests to make sure software works well in different places:

Getting ready for localization testing

Choosing target markets

When picking markets for your software, think about:

• How big the market is and if it's growing
• What languages and cultures you need to work with
• How many other companies are selling there
• What laws you need to follow

Use market reports, online data, and social media to learn about markets.

Setting localization needs

After choosing your market, decide what to change:

• Translate your software
• Make it fit local customs
• Use the right date and number formats
• Follow local laws

Use translation tools and localization software to help.

Making a test plan

A test plan should say:

• What you want to test
• Which parts of your software to test
• How you'll do the testing
• When you'll do each part

Use test plan templates and project tools to help make your plan.

Building your testing team

Your team should have:

• People who speak the local language and know the culture
• People who know how to test software
• Someone to manage the project

Use job websites or freelance sites to find team members.

Tips for better localization testing

Do market research

Market research helps you understand your target audience better. It shows you what they like and what's important in their culture. Use these methods to learn about your target market:

• Online tools
• Social media
• Customer feedback

Choose what to localize first

Focus on the most important parts of your software for localization. This helps you use your resources well. Pick the features that matter most to your target audience.

Check formatting and cultural fit

Make sure your software fits the target market's standards:

Ensure everything is appropriate for the target audience.

Mix manual and automated tests

Use both manual and automated testing:

Using both helps make sure your software meets the required standards.

Work with local experts

Team up with people who know the target market well:

• Translators
• Cultural consultants
• Local testers

They can help you understand the market's language, culture, and tech needs.

Test throughout development

Test for localization issues while you're building your software. This helps you:

• Find and fix problems early
• Avoid delays
• Keep costs down

Steps in localization testing

Set up your testing space

To set up your testing space:

1. Find out what tech your target market uses
2. Make a test setup that matches their devices and software
3. Install needed tools for testing
4. Set the right language, date, and money formats

Create test data and scenarios

To make test data and scenarios:

1. Pick the main parts of your software to test
2. Write tests for different situations
3. Make test data that fits the target market
4. Check that your tests cover everything important

Run the tests

To run the tests:

1. Do the tests in your test setup
2. Look for any problems
3. Write down what you find
4. Look at the results to spot patterns

Record and report issues

To record and report issues:

Retest and confirm fixes

To retest and confirm fixes:

1. Do the tests again to check if problems are fixed
2. Make sure fixes work and don't cause new issues
3. Write down the new test results
4. Check if the software is ready to use

Localization testing checklist

User interface items

Check these UI parts:

Make sure everything looks good and fits well after translation.

Text and translations

Check all text is correct:

• Translations make sense and use good grammar
• Words and phrases fit the local culture
• Text sounds natural in the target language
• Special letters and symbols show up right

Date, time, and number formats

Make sure these match local ways:

Money and measurements

Check these are right:

• Money symbols and formats
• Unit conversion (e.g., miles to kilometers)
• Show right units (e.g., Celsius or Fahrenheit)

Character sets and encoding

Make sure letters and symbols work:

• Special letters show up right
• Non-English writing systems look good
• Text encoding is correct (e.g., UTF-8)

Legal rules

Check the software follows local laws:

• Data privacy rules
• Tax laws
• Special rules for certain industries

Cultural awareness

Make sure it fits the local culture:

• References make sense to local users
• Respects local customs
• Avoids offending anyone

Tools for localization testing

Testing frameworks

Testing frameworks help organize and run localization tests. Here are some useful ones:

Automated testing tools

These tools speed up testing by doing repetitive tasks:

Translation management systems

These systems help manage translations and can support testing:

Pseudo-localization tools

These tools mimic localization to find issues early:

These tools can help make localization testing easier and more thorough.

Common localization testing problems

Dealing with text size changes

When translating an app, text size can cause issues. Different languages need different amounts of space. This can lead to:

• Text that doesn't fit
• Layouts that look wrong
• App crashes

To fix these problems:

• Use layouts that can grow or shrink
• Test with fake translations early on
• Change font sizes to make text fit
• Set limits on how much text users can enter

Handling multiple languages

Supporting many languages can be hard. This is especially true for languages that write differently, like right-to-left languages. To handle this:

Working with right-to-left languages

Languages like Arabic and Hebrew need extra care. They're written from right to left. To support these languages:

• Use fonts that work for right-to-left text
• Test your app with these languages
• Format things like dates the right way
• Try tools that make fake right-to-left text for testing

Keeping things the same across devices

Making sure your app looks and works the same on all devices is important. To do this:

Checking localization testing results

Key measures for localization testing

To check how well your localization testing is going, keep track of these important numbers:

By watching these numbers, you can see what's working well and what needs to get better.

Looking at user feedback

It's also important to ask users what they think. You can do this by:

• Sending out surveys
• Talking to small groups of users
• Watching users try out your product

This helps you understand what users like and don't like, so you can make things better.

Ways to keep improving

To make your localization testing better over time:

Wrap-up

Key points to remember

Localization testing is important for making software work well in different languages and cultures. Here are the main things to keep in mind:

By following these steps, you can make your software better for users around the world.

What's next for localization testing

As more people use software from different countries, localization testing will become even more important. To stay ahead:

• Keep learning about new ways to do localization testing
• Use computer tools to help with testing
• Keep improving how you test
