Types of Localization Bugs with Examples

Types of Localization Bugs with Examples
September 11 11:16 2018 Print This Article

Localization testing is an important part of a development lifecycle of the application, which is designed for the international market. It checks whether the software is adjusted to meet lingual, culture and other requirements of each separate region.

Localization itself is not an easy process, because every country has a lot of peculiarities to be taken into consideration. Consequently, there are always a lot of issues detected during localization testing. Today we are going to present the most common of them that QA engineers frequently face during localization testing.

Missing translation

There is always a possibility to miss this or that text fragment while translating a complex functionality. Often, it happens even with simple elements, like hints or pop-ups.

Missing translation example

Truncation

Sometimes, when a word is translated from one language to another, it can take more space than in the original version. For example, English “no” in German is “nein”, which has more characters. Or compare English “Have a nice day!” to its German equivalent “Ich wünsche Ihnen Einen schönen Tag!”.

The words can be truncated to fit into necessary room. That is also a localization bug.

Truncation example

In order to prevent words truncation during localization, it is recommended to leave around 30-35% of spare space within every block of words. However, sometimes a translation decreases the number of characters in the target language, but this commonly doesn’t cause problems.

Over-localization

Not everything should be localized. For example, logos, abbreviations, trademarks, etc. should be kept as they are. Also, in some cases to use an English word is even more appropriate than to use its translation.

In order not to “over-localize” the content, it is better to create a list of elements which should be used in the original language without translation.

Missing text

During localization, it happens that the text gets lost. Often, it is not obvious at first sight. In order to spot an issue, a tester should use two devices during testing – one with an original language build, and another with a localized version. This way it is easier to check whether there is a text everywhere, where it is needed.

Missing text example

Inconsistent terms

If there are terms in the application, they should be translated the same way throughout it. It is recommended even to make a translation library, and share it with all the parties involved in the localization process.

Encoding issues

If the application is not originally intended, for example, for the Chinese market, it may have problems with displaying Chinese hieroglyphs. The same can happen with a range of other characters. This problem is caused by encoding, and it should be anticipated during the development stage.

Encoding issues example

Data and time formatting

Every region has its own data and time formats, for example, some countries have 12-hour and some 24-hour clock. An application should support various local calendars and data formatting to avoid this issue.

Here is the example of different data formats around the world.

US – month-day-year (09-11-2018)
China – year-month-day (2018-09-11)
The Russian Federation – day-month-year (09-11-2018)

Hardcoded elements

Hardcoded elements are those directly embedded into the code. They often cause problems when changing the location, as far as they will be still displayed in the original language. Hardcoded elements are not the best practice for developers. However, they often insert them in some static elements, e.g., placeholders or headings.

Different names for the same elements

While translating, it is important to use the same translation for each element throughout the application. Sometimes, you can encounter different names for the same elements even within one window. It can really confuse users.

UI defects

User Interface defects can be caused by localization issues, mostly when it is not enough room for the translation of the elements. Consequently, we have incorrect buttons and drop-down sizes, or alignment problems.

UI defects example

Inaccurate translation

Localized products are mostly intended for native speakers, which can easily notice even a slight deviation in the meaning of a translated text. So, the translation should be performed by professional translators and linguist who can convey an exact meaning in a target language.
