Mike Harris' Testing and Quality Blog
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 …

I recently saw a comment about how testers should be able to use decision tables to aid their testing. I decided to refresh my understanding of them and these are the notes I created about them. Decision tables are an analytical tool. They are used to describe logic and can be helpful in understanding the …

I have been using Ghost Inspector to automate tests that run through the UI for a few years. It is an automation tool which says “No coding required”. If you are not a programmer you can use Ghost Inspector to automate tests. You can also use Ghost Inspector to learn about development practices and coding. …

Juran’s Quality Control Handbook is a reference book for people who “are involved with” quality. The 4th Edition of the handbook includes an article by Frank M. Gryna about Quality Costs. Gryna says that as companies began to extend the concept of identifying costs to quality they found that costs relating to quality were much …
I have worked in lean or agile teams for a number of years and developing my knowledge of lean and agile has helped me. The Deming Cycle is something I have found helpful to understand because it is a part of agile and lean and it is also about continuous improvement of quality. Engineering teams …
I am learning JavaScript because it helps me in so many ways when I am testing. Many apps have JavaScript sandboxes that enable you to write some JavaScript that adds to your testing. Examples of where you can write JavaScript are the Tests tab in Postman, and browser dev tools which enable you to write …

An automated test strategy will normally include tests that are automated through the UI, and unit tests. It is an advantage if an automated testing strategy also includes testing that is automated via the API. Automated tests need to run quickly so that developers get fast feedback on their work. Tests that are automated via …

W. Edwards Deming wrote that improving quality results in a chain reaction “lower costs, better competitive position, happier people…and more jobs”. Deming worked in Japan after World War Two where he helped rebuild the Japanese economy. He received honours from the Emperor of Japan and the President of the USA. His work underpins agile, lean …

We want to find bugs as early as possible so that the cost of fixing them is as little as possible. The earlier a bug is found the cheaper it is to fix. If a bug is found and fixed in a specification before any code is written then it costs very little to fix. …

What does it mean when a card is put into the Done column? Done can mean that the coding is completed, it can also include that the code has been reviewed, that it includes unit tests and many other things. Teams sometimes create a “Definition of Done” to state exactly what “done” means and this …

Identifying risks to their work helps development teams. Recently I spoke to a team who had talked through the ways in which their work could fail, and built on this to identify risks to their work. The team adapted Failure Modes Effects Analysis (FMEA) to suit their needs. FMEA is a technique that is used …

Quality is Free is the name of a book by Philip B. Crosby in which he argues that quality is free and lays out a Zero Defects program to improve quality. Crosby’s ideas, along with Deming, Juran, and others, influenced the Quality Movement. Crosby says that there is a cost of quality. The cost of …
There is always more testing that can be done on a feature but there are reducing returns on testing a feature over time. At some point you need to stop testing, and the question as to when to stop is sometimes a difficult call. Also, sometimes there is more than one feature to be tested. …
We want to create quality features, products and services. Using a framework to think through how to achieve this is helpful as the framework ensures that vital points are covered. Testers can provide value by understanding these frameworks and using them to shape their own thinking in order to be able to prompt and/or lead …
