Software Testing Blog

In the third and final installment of our Testing the Limits interview with Google’s Patrick Copeland, we get him to share his advice for youngsters who want to reach tech executive status; his programming language of choice; mobile testing challenges and his New Year’s resolutions (for testing of course). In case you missed our previous interviews, here’s Part I and Part II.

uTest: What advice would you give to young software turks who aspire to become a senior tech exec at a global powerhouse?

PC: Here’s my advice:

1. Be technical: At Google all of our engineering execs have very strong technical backgrounds. They were programmers and many of them can – and do – still program today. Advice: remember your computer science and stay sharp.
2. Be a connector and innovator: One exec commented that his job could be described as being “a very expensive email router.” Get connecting within your company and establish a network of strong peers.
3. Drive your career: Don’t wait for someone to recognize you. Inform people about your plans and successes. You are your own best billboard. People will create a myth about you, like it or not. If you are smart you’ll help them create the myth you want them to have.
4. Play to your strengths: Pick projects that you are passionate about and where you can rock worlds.
5. Bite the hand that feeds you (a little): Don’t be a jerk, but make sure you don’t go passively along with bad ideas. A weak willed tester is a bad thing. Make your concerns known…and know when to fold.
6. Go where there’s opportunity for growth: Not all projects or companies can offer you an ability to grow. Move when you think you are topping out. The biggest mistake I’ve seen is staying too long in a place that hinders growth.

uTest: Google is booming in the mobile apps space; what QA testing challenges do mobile apps present that web or desktop apps do not?

PC: Where do I begin?

A good starting place is the huge diversity of devices. For instance, significant variations in HW and SW: OS, memory, processors, screen size, and input methods. Just having access to a fraction of the devices on the market for testing purposes is a challenge.

On top of that, if you want any automation, you have the problem of simulating input and capturing the actual output on the device. We needed to develop tools that allow up to test and build against multiple platforms. Normalizing the testing is tough. We debated record and playback vs writing abstraction layers vs other methods. All can be brittle in the extreme. We also needed to think about the long term cost of maintaining tests suites on fast moving SUTs.

A couple other issues are the carrier networks and the numerous languages. As I said, I could go on for a long time, but I believe I hit some of the major pain points. Even with all of the automation in the world, a community based test approach can be complimentary.

uTest: Is there a particular programming language to which you are loyal (PHP, Java, Ruby, etc)?

PC: Nope. Not really. At Google the most common ones are Java, JavaScript, Python, Perl, and C++. Perhaps a personal failing, but I still think in C and my code ends up looking kind of C-ish even if it’s in another language. My preference also depends on the thing I’m trying to do, obviously each has strengths and weaknesses.

On a similar topic, I recently met famed computer language innovator, Niklaus Wirth at the last GTAC conference in Zurich. He had in interesting comment on testing and quality, “The experience, judgment, and intuition of programmers who have survived the rigors of testing are what make programs of the present day useful, efficient, and correct.” In other words, you can’t test quality in and quality comes from experience.

uTest: Any new year’s resolutions for Google’s testing & QA efforts?

PC: Yes. Every year I write up a “one pager” describing what I think we need to do. I try to stay focused on general productivity and not specifically testing. Testing is one tool among many we use to make software high quality and delivery faster. We are doing well on many levels, but we aspire to do even better. Here are a few of the high level bullets:

• Greater release velocity. We apply appropriate use of automation, tools, process, and information that solve Google challenges. We introduce and use metrics that fit naturally into the product cycle. We are introducing key metrics that are actionable and representative of the health of the project that allow team members to understand issues and take action quickly.
• Cohesive tools. We’ve built an impressive set of tools that have made significant impact. In our next stage, we need to better integrate some of the data and tools and focus on accelerating the end to end developer workflow. This includes identifying bottle necks that slow people down and keeping an eye on innovative ideas coming from product teams. And of course, continual improvement of build and test speed.
• Driving improvement upstream. We will take advantage of our ability to make good ideas useful across the company. We use our broad view of projects to push adoption of ideas and methodologies that work. We look for ways to compliment existing product strategy by identifying changes where the adoption is in a project’s self interest. We constantly evaluate our own practices by looking at their effectiveness in relation to customer and business needs.

uTest: You went to school at University of Arizona, and USC; you’ve worked at Microsoft and Google; are you a lifetime west coaster or has it just worked out that way? Also, Dodgers or Giants (or D-backs)?

PC: Are there any good East Coast teams? I heard it was so foggy the other day that the Washington Nationals couldn’t even see who was beating them.

They may not be sports teams, but I’m a fan of the testing teams we have on the east coast: NYC “Bubble Sorts”, Boston “Red SOX”, and Pittsburgh “Open Sourcers”. BTW, we just hired a Test Director on the East Coast named John Turek who’s looking for a few good players.

BTW, I actually have lived in other places. My family lived in Maryland and Tallahassee for a bit. I also lived in Madagascar, which is definably on the East Coast (of Africa).

uTest: What sites, blogs or magazines do you read to stay ahead of the curve in the areas of business, technology, etc?

PC: Track and Field, Cosmo and, occasionally, Monster Truck Weekly . Seriously, I have a bunch of custom news feeds on certain topics, like Google, our competitors, and testing. I also read wsj on line and at least one interesting industry technical paper per quarter.

Editor’s note: We hoped you’ve enjoyed our interview with Patrick Copeland. If you have suggestions for our future Testing the Limits guests, we’d love to hear them.
