Localization QA Testers: Guardians of Quality

Last Updated May 10, 2013

Since I manage a team of localization QA testers, localization engineers, linguists and translators and I continuously hire new members, I’m often asked to explain how the different roles interact and what they’re responsible for.

Today I want to focus on localization QA testers.

They’re an integral part of the localization process, but their role is sometimes not fully understood, or not as easy to see.

We rely on them to make the final product really shine, so they deserve some recognition!

Why do localization QA testers play such a vital role in the localization process?

From the Past to the Present of QA Testing

In the past, when much of translation was focused on documentation, localization QA testing was not nearly as common.

Final reviews were typically completed by translators just before the files were sent to publishing.

The work and expertise of localization QA testers became a necessity in the translation process with the rise of digital content and localization activities for mobile applications, software and websites.

Putting it simply, localization QA testers ensure the quality of the localized product.

What are Localization QA Testers and What Do They Do?

It’s a good idea to begin with an explanation of precisely what localization QA testers do.

This will help with understanding the qualities that they need to possess to be successful in what they do.

Unlike translators, who mostly work with text which is isolated from the rest of the user interface, localization QA testers are the very first people to see the localized product in its entirety – translated text, images and the rest of the user interface all together.

They get to experience the project in the way it will be consumed by the end users.

The localization QA testers then have to analyze the product in three ways:

1. Linguistic testing

2. Cosmetic testing

3. Functional testing

The Qualities of Localization QA Testers

So, keeping all of this in mind, what characteristics make for successful localization QA testers?

The job may seem easy at first, but in reality it’s complicated and demanding.

In a nutshell, it requires a combination of language skills, strong computer literacy and great attention to detail.

It may be challenging to locate testers who have all of these skills. Ideally, localization QA testers should have:

When you’re curious about something new, there’s nothing better than consulting an expert. To get even more insight, we’ve asked some friends to answer a few questions about the challenges and rewards of being a localization QA tester.

If you meet someone at a party and they ask you what you do, how do you describe your job?

When I say that I am a “testeur”, I get the look “Huh??” Then I say “I review the quality of the adaptation of a product into French”, and people understand. For most people, I have a weird job, out of the ordinary. I have to say that I moved back to my French hometown and it doesn’t take much to get off the beaten path.

What’s the most common localization mistake that you see?

Format issues: French uses a lot more words than English, so often, French text doesn’t fit in buttons, windows, boxes; there is a lot of overlapping… Then comes punctuation standards and special characters.

What skills do you think are important in LQA?

I think a tester needs to be focused, flexible, have good communication skills and of course be comfortable with working remotely, not to mention have an understanding family.

What’s the most difficult part of your job?

Because I work from France mostly with American vendors, the time difference is sometimes difficult: I make myself available basically from when I wake up to bed time (i.e. sometimes very late). Worst case scenario is when I start a job in the morning (night time in the US or Canada), I have a crucial question (links that don’t work, sites under maintenance, instructions related questions…) and I don’t get an answer before mid afternoon. The stress level can get high as the deadline approaches.

Also, the workload fluctuates: some weeks I have no work, others, I have too much.

What do you love the most about your job?

I love my flexible schedule.

I like the fact that I rarely work on the same type of project and if I do, I can only get better at it.

I like all the aspects of the localization/adaptation industry whether it’s testing, translating, reviewing, transcribing, subtitling etc.

They are the guardians and have the final say about the quality of your product before it reaches the eyes of your customer.
