On major software projects like the OSS you’re building, testing is an important phase of course. You’ll have undoubtedly incorporated testing into your planning. After all, testing is a key component of any Software Development Life Cycle (SDLC). There are various SDLC models / methodologies such as Waterfall, V-Model, Agile and others that you can consider.
Unfortunately, most OSS project teams tend to underestimate the testing phase, thinking it can just fit in around other major activities towards the end of the implementation. Experienced testers will suggest that they should be involved right from the requirement capture phase, because they’ll have to design test cases to prove that each requirement is met.
More importantly, your test strategy and test phase transitioning can play a major part in maintaining momentum through a project’s delivery phase. We’ll look into a number of related details in a series of posts this week.
Today we’ll look at the V-Model. It can be a helpful model for mapping requirements to test phases / cases. The diagram below, which comes from my book, Mastering your OSS, shows a simplified, sample version of the V-Model. It highlights the relationship between key test artefacts (eg plans / designs / specifications / requirements) on the left with the corresponding test phases on the right.
Your documentation and test phases will probably differ. You can find a discussion about some other possible OSS test phases here.
We’ll take a closer look tomorrow at how your different test phases could map to the OSS environments you might have available.
Standing out in a highly saturated and fragmented OSS market can be really difficult. We’re regularly involved in bake-offs where we see dozens of OSS
