Fighting Test Flakiness: A Disease that Artificial Intelligence Will Cure
Artificial Intelligence (AI) is making it possible for computers to diagnose some medical diseases more accurately than doctors. Such systems analyze millions of patient records, recognize underlying data patterns, and generalize them for diagnosing previously unseen patients. A key challenge is determining whether a patient's symptoms and history are attributed to a known disease or other factors. Software testers face a similar problem when triaging automation failures. They investigate questions like, Is the failure due to a defect, environmental issue, or nondeterministic test script?...
The Logic of Verification
Software testing is sometimes described as “verification and validation”—or, according to Wikipedia, “the process of checking that a software system meets specifications and that it fulfills its intended purpose.” Yet, renowned tester and teacher Michael Bolton argues, if we examine the concept and logic of verification, we quickly recognize that there are serious limitations to what can and cannot be checked and verified. This is not to say that checking is a bad thing—on the contrary; checking can be very valuable. Still, it’s important for testers and their clients to recognize the...
The Art of Software Investigation
Although processes and tools play an important role in software testing, the most important testing tool is the mind. Like scientists, testers search for new knowledge and share discoveries—hopefully for the betterment of people’s lives. More than sixty years ago, William I.B. Beveridge reframed discussion of scientific research in his classic book The Art of Scientific Investigation. Rather than add to the many texts on the scientific method, he focused on the mind of the scientist. Join Ben Simo as he applies Beveridge’s principles and techniques for scientific investigation to software...

Improve Planning Estimates by Reducing Your Human Biases
PreviewAre you puzzled about why your estimate turned out wrong, or stressed from working to meet an impossible deadline? Some teams on inaccurately estimated projects suffer stress, burnout, and poor quality as pressure is applied to stick to an unrealistic schedule. Such project teams also descend into irrational decision-making—with potentially catastrophic consequences. Frustratingly, even when teams perform well, they are often judged by their failure to meet impossible deadlines. Andrew Brown will show how estimation errors are caused not just by new technology or intentionally...
Managing BDD Automation Test Cases inside Test Management Systems
Behavior-driven development (BDD) has been around for a while and is here to stay. However, the added abstraction levels pose a technical problem for writing and managing tests. While BDD does a great job of marrying the nontechnical aspect of test writing to the technical flow of an application under test, keeping this information under source control becomes problematic. Frameworks such as JBehave, Cucumber, or Robot give subject matter experts that additional ability to write tests, but they are often restricted access from them; because people treat test cases as code, they get stored...
How to Automate Testing for Next-Generation Interfaces (BOTs, Alexa, Mobile)
PreviewToday’s IT systems communicate with customers through multiple points of engagement and various interfaces, ranging from web, mobile, and voice to BOTs and apps like Alexa and Siri. Sanil Pillai says these systems need to provide seamless handoffs between different points of interaction—while at the same time providing relevant and contextual information quickly. To accomplish this, a team must be able to successfully pair device hardware capabilities and intelligent software technologies such as location intelligence, biometric sensing, and Bluetooth. Sanil shows that testing...
Automation and Test Strategies to Save Our Project from the Brink of Collapse
Teams are sometimes asked to turn a mess of undocumented, poorly structured legacy code into a robust product under impossible deadlines. Test strategies blending automation, exploration, and refactoring can help focus development efforts and converge even the most chaotic projects. But, where do you start? Join Jonathan Solórzano-Hamilton as he shows how automation can help drive products into a state of release readiness. Learn how refactoring, test-driven development, SOLID principles, dependency injection, and mocking frameworks help break down complex development problems into...
Compliance and Agility—How It Can Be Done
PreviewDelivering a compliant product is a resource intensive and challenging activity for most teams. Whether a team is trying to adhere to company, industry, or international standards, it needs to produce deliverables under tight deadlines with the right level of quality. When you work with Forensic teams the stakes are high! Next Generation Sequencing (NGS) is a new forensic DNA sequencing technology which can result in increased detection ability for degraded and complex mixture samples. It can also provide ancestry and physical trait information which help's narrow down suspects....

Frontend Testing: Stepping in and Collaborating with Developers
Testing is shifting left, moving closer to testing the code itself before the full product is ready for release. While the backend world already has established methodologies for testing, frontend developers and testers are still trying to figure out how to work together to effectively test the code. Gil Tayar suggests testers need to communicate with the frontend developers to understand the framework by which frontend code is tested, the various kinds of testing that can be performed on frontend code, and which tools can be used. During this session, Gil helps ease your fear of the...
Being More Agile Without Doing Agile
The most common requests Dawn Haynes gets as a consultant these days is to help testers transition to an agile development process, or to help testers be more effective in “agile-ish” environments. But Dawn recognises that transforming the process and the environment is not enough. Interestingly, the core answer to these questions starts with forgetting the process for a moment and focusing on yourself and what you’re trying to accomplish. Being agile starts with a mindset and an attitude that drive focus, approaches, and solutions. When you start there, the path to improvement can almost...
Building a Modern DevOps Enterprise Testing Organization
The DevOps movement is front and center across enterprises. Companies with mature systems are breaking down siloed IT departments and federating them into product development teams and departments. Testing and its practices are at the heart of these changes. Traditionally, development organizations have been filled with mostly manual testers and a limited number of automation and performance engineers. Adam Auerbach says this has to change. To keep pace with development in the new “you build it, you own it” environment, testing teams and individuals must develop new technical skills and...
Working with Anxiety: From Personal Weakness to Career Strength
PreviewEach of us has personal weaknesses that are often perceived to have negative impacts on performance and capability in the workplace. When this weakness is prominent to yourself or others, are you capable of benefiting IT teams and qualified to do the job? In dealing with negative impacts of her Generalized Anxiety Disorder, Julene Johnson falls into this category and has experienced personal doubt in her ability to perform her job well. Over time, however, she’s noticed that habits and techniques developed while dealing with anxiety can be applied in a manner that improves her life...
What Aircrews Can Teach Testing Teams
PreviewUnited Flight 232 should have crashed with all 296 lives lost. Asiana Flight 214 should not have crashed at all. But the reality is very different. Peter Varhol and Gerie Owen explain that the critical difference between the two flights was the interactions of their respective aircrews. United Flight 232 divided up responsibilities and worked as a team, using Aircrew Resource Management (ARM) to guide how the crew behaved during the flight, and especially in a crisis. Asiana Flight 214 deferred to the captain, neither communicating nor questioning his decisions in crisis. ARM helps...
Testing Imprecise Requirements
Articles on abc.net and elsewhere reported that Volvo has recently discovered a non-traditional requirement: Any self-driving vehicle approved for use outside Australian cities must recognize kangaroos on or near the roadway and take proper actions. The kangaroo’s bounce confused the large animal detector! In this session, industry expert David Gelperin shares a new perspective on the value of imprecise requirements and explores the nature of testing them. Excess precision may hamper the development of optimal solutions by excluding effective designs. Imprecise statements reduce the risk...
