Reducing Verification Lead Time by 50% by Lowering Defect Slippage and Applying AI/ML Techniques

Can we increase our flexibility? Can we increase our test coverage? Can we increase our efficiency? And is it possible to reduce our verification lead-time by 50%? One company challenged itself with these questions. This article explores two important “‘pillars”’ of their testing strategy: shifting left and using state-of-the-art techniques to support verification activities.

The Unit in Unit Testing

In this article, we will focus on how developers should consider using fake objects instead of mock objects, as fake objects offer similar isolation benefits while driving high confidence, clear documentation, and loose coupling between implementation and test code.

How I Contributed as a Tester to a Machine Learning System: Opportunities, Challenges and Learnings

Have you ever wondered about systems based on machine learning? In those cases, testing takes a backseat. And even if testing is done, it’s done mostly by developers themselves. A tester’s role is not clearly portrayed. Testers usually struggle to understand ML-based systems and explore what contributions they can make. This is a journey of assuring quality of ML-based systems as a tester.

An Ode to Unit Tests: in Defense of the Testing Pyramid

The switch to the testing diamond approach has not effectively addressed issues caused by the testing pyramid. Instead, the focus should be on using unit tests correctly within a testable architecture.

How We Built Testability with Psychological Safety

Testability can enable teams to make changes to their code bases without requiring extensive regression testing. To build testability, team members must collaborate and leverage each other's unique skills. Unfortunately, effective collaboration does not come naturally to people and therefore needs leadership to nurture people's ability to speak up and share their knowledge.

POCs, Scrum, and the Poor Quality of Software Solutions

POCs and Scrum can play a critical role in implementing Quality software solutions. Poor quality often starts with a POC that was prematurely turned into the development pipeline. Scrum short sprints often create an environment most conductive to working reactively to constantly-changing requirements making it hard for developers to prioritize and achieve Quality over the course of the project.

Open-Source Testing: Why Bug Bounty Programs Should Be Embraced, Not Feared

The growing importance of the Web3 ecosystem based on blockchains shows how important community test programs are. Some within the testing community see this trend as a threat. However, it is actually an opportunity. Bug bounties and open-source test contributions are a great tool for test teams, and there is every reason for testers to embrace this new trend rather than to fear it.
