Identifying what states exist in functionality and how changes in state take place enables testers to identify tests that should be executed. State transition diagrams provide simple notation for summarising states and how changes in states take place. I recently used a state transition diagram on a project and it helped me identify the tests …

It is helpful for a tester to be able to program as it enables a tester to get a better understanding of the application they are testing. Being able to code also helps create test data, automate tests and build a better relationship with developers. But which programming language(s) should a tester learn? Over the …

Recently I was testing the messages sent from an app to the user when I noticed that the messages were dependent on the interaction of three conditions. I used a decision table to analyse the messaging because decision tables show how many tests are required to test something that is affected by a group of …
“Artificial intelligence and Software Testing” is edited by Adam Leon Smith and has recently been published by the British Computer Society. The book covers both using Artificial Intelligence (AI) to test software and testing AI systems. The book will help testers who want to learn about AI and testing. Rex Black writes in the introduction …

When I started as a tester I learned that test documentation, such as test plans, needed to gain approval from the Director and could be regarded as a project deliverable. I have learned that this is not helpful and that test documentation should support testing and the development. I remember that, before testing started, we …

Sometimes testers need to “coach”, when I do so I draw on my knowledge as a junior cricket coach and use the PoP framework. My cricket coaching qualification also included using the coaching tools that best suit the player, outcome and practice. The tools that we can use to coach are: Having a list of …
Sometimes testers need to “coach” and when I do I use a coaching framework to help me. At the weekend I coach junior cricket and I use what I have learned from cricket to help me as a tester. The PoP framework we use in coaching cricket can be useful to us as testers. In …
Joseph Juran wrote in the 5th Edition that Juran’s Quality Handbook ”is a reference book for all who are involved with quality of products, services, and processes”. I find it a useful book to refer to if I am thinking about a problem. There are eight editions of the Juran’s Quality Control Handbook. They are …
Engineering teams often keep metrics on their work, but are these metrics always helpful?. Metrics could be something that the manager or director has asked for or metrics something that the team has created to help the team. I have found that creating metrics on quality is something testers often do. Creating useful metrics is …

Jobs Theory gives us a way of understanding clients by asking what job did they “hire” a product or service for. An example of Jobs Theory is given in “Competing Against Luck”: by Clayton M. Christensen, Taddy Hall, Karen Dillon and David S. Duncan. The example they give explains why people “hired” milk shakes. Research …
Creating a tree diagram can be a helpful way to visualise functionality that is accessed via hierarchical structures like menus and the tree diagrams can help to plan testing. In my mind’s eye I often see functionality as a tree diagram. C.S French says that trees are “hierarchical data structures rather like the familiar family …

I wrote our test strategy after taking Michael Bolton’s Rapid Software Testing course using what I had learned on the course. I reviewed the strategy recently and one of the thoughts I had while reviewing it was why should you write a test strategy? There are many good reasons to write a test strategy and …
