Ways to Generate Quick Test Ideas

As testers, we look at everything with a critical eye. As soon as something comes up for testing, our instinct is to get down to examining it and looking for problem areas. After getting a written test script, a new tester would be tempted to begin executing scripted tests right away.

But stopping to gather our thoughts about possible test ideas first is a smarter approach that leads to better, more unbiased test coverage. However, we don’t always have a lot of time to imagine scenarios and different paths. Luckily, there is always some planning we can do beforehand.

In my article published at Gurock Testrail blog I shared some tips for generating test ideas in a time crunch.

Revisit classic test techniques

Our old, trusted test design techniques like boundary value analysis, equivalence class partitions, decision tables, and state flow diagrams are always a help when thinking about test cases. Although most of them are ingrained in the thought process of a tester and are mostly common sense, giving them a revisit, however informal, may still give us some more test ideas.

For example, creating a quick decision table for the interaction of two or more variables to observe the behavior of the system may reveal some unique combination that we might have missed. Or a quick boundary value analysis for the age field in our we form may show us a special case we might have missed.

Similarly, using state transition diagrams to draw end-to-end flows can help not only the testers, but also the developers in imagining the overall system flow and revealing problem areas.

Look at the history

The history of the project or the system can give us many insights into what we are dealing with, where the common defect clusters are, and the most problematic components.

If you are new to the test team, start by having a look at the defect tracking from past sprints or releases. You can then define and think of more test cases based on past defects and the components that have had the greatest number of defects.

If you’ve been part of the team for a while, you are probably intuitively bound to focus on these areas. But even then, it will help to consciously make an effort to list the most common types of bugs encountered and most problematic areas based on your experience. This will help not only you, but also your new and junior team members. Read full post->
