Episode 33 —Testing in Data Science

In this week’s testing podcast episode, Brian explores testing in data science with the famous Katharine Jarmul. Katharine is a expert in data science and machine learning. She mainly uses python to write unite tests for her projects. I picked this podcast because after listening to this, I learned more about how to put together testing teams, how to manage and direct traffic in a testing team and how to be the driving force for success in the team. According to her, no matter how much we know as a team, with each testing project, we need to bring together all our resources and ideas. Testing often goes out of the scope of what is considered the norm. This is because in testing, we normally try to find the boundaries and limits if products and software. As a teacher and owner of a consulting company, Katharine often spends her days developing testing strategies that requires the implementation of new and modern testing technologies such as Integrating QA through agility and TCoE , Higher Automation Levels with a focus on security and Context driven testing.


Integrating QA through agility and TCoE

Though agile development teams have been around for a long time, agility in testing is still nascent. With the continuous pressure to quickly deliver software, businesses are investing time and money into setting up a TCoE with the objective of reducing CoQ, increasing test effectiveness and generating more ROI out of testing. From 2011 to 2014, the number of operational TCoEs has increased from 4% to 19% and is expected to increase further in the future.


Higher Automation Levels with a focus on security

System robustness and security has always been a top priority but with growth in social media and mobility and need for software that can be integrated to multiple platforms, systems are becoming more vulnerable. There is a pressing need to ensure enhanced security, particularly in applications handling sensitive data. This is causing QA to focus more on security testing.


Context driven testing

The challenge for businesses to maintain central hubs of hardware, middleware and test environments necessary to comprehensively test them has caused context driven testing to become more popular as it ensures more testing coverage from diverse angles. It is expected that this will impact skill development among testers, as there will be more demand for testers with exposure to different contexts.
