The Polish Championship in Software Testing and the biggest testing conference. Join us - become the champion!
Data and web services are bigger than ever and Big Data requires Big Testing. Big data product testing is definitely challenging: in such a massive amount of data, issues can be very complex, hard to find and some of them may even be hidden within unprocessed data.
A couple of years ago, I made a drastic career change: from a manual software tester in a big company, I became the first full time tester for a data driven merchandising tools startup. The first product I had to test was a web service which predicts shoppers' perfect size on e-commerce websites. Surprisingly, this little web service turned out to be fueled by staggering amounts of BIG data. Being new to the world of data driven products, I felt overwhelmed at the start, but, nevertheless, I dived in and slowly but surely learned how to find my way around an area that was a black box to me.
In this session, I will share the story of my progression from a manual UI tester to a data-savvy tester capable of interpreting huge chunks of data. I will talk about the stress of facing such an imposing challenge and how professionally rewarding it was when I finally managed to get to know the beast that is Big Data by finding the right tool. Finally, I will also talk about how understanding the data gave me a better insight into the product itself and helped me to become a better and more pro-active tester.
