  • Sources of cognitive bias and their impact on software testing

    Researchers have taken a careful look at the way humans think and they have noticed how sometimes people are influenced by a number of factors which cause undesirable bias in the way they take decisions. This research* has been applied principally to business leaders and managers, but it is also highly relevant to the area of software testing.

    In this presentation, we will explore in an easy to follow style the principal way in which people think and take decisions. We go on to describe the main sources of bias and how these impact various aspects of software testing, such as:

    • Creating risk-based test strategies
    • Evaluating the return on investment from testing
    • Estimating testing effort
    • Performing exploratory tests
    • Reporting defects
    • Leading teams

    The presentation is intended for anyone involved in taking decisions in testing. In other words, all of us! You will gain valuable insights into everyday software testing situations where cognitive bias can influence decision-taking. Understanding these situations will help us limit their impact on our projects and their team members.

  • With the increasing use of mobile apps and web-based applications, usability is becoming more and more important. Bad usability can lead to the rejection of an application and damage the image of organizations. This tutorial will give you a full overview of what usability testing is about and how you can approach this important testing aspect successfully. It describes the various aspects to consider: usability, user experience and accessibility. After that we cover commonly used standards and how to the use different approaches in evaluating usability. You will appreciate what is different when testing usability compared to functional testing and significantly raise your awareness. The tutorial is presented in an uncomplicated way with examples.
