Principle # 6: Testing is Context Dependent
Testing isn’t a one-size-fits-all process — it’s different for every project.
Whether it's safety-critical software, an e-commerce app, or an Agile project, each context requires a unique expertise. Understanding these differences is crucial in our role as testers.
It’s all about adapting our approach to fit the context and the specific risks involved.

Principle #5: The Pesticide Paradox in Testing
The idea is simple: if we keep repeating the same tests over and over, eventually they’ll stop finding new bugs. This is why it's crucial to constantly update and create NEW tests to catch those pesky, hidden defects that might otherwise slip through.
Regression testing remains a critical part of this process. By running automated regression tests, we ensure that software changes don’t introduce unexpected side effects. It’s all about keeping the software stable and defect-free, at least insofar as the test coverage that has been written.

Today, I'm taking a closer look at ISTQB testing principle #4: Defects Cluster Together
In software testing, it is commonly observed that a small number of modules contain most of the defects , especially during pre-release testing. These modules are often responsible for a majority of operational failures.
Defects tend to group together. Defects love parties. When a bug is found in one area, there is an 80% chance another will be found in the same area, and only a 20% chance that the defect will appear elsewhere—unless the next area is another defect cluster.
This information may feed into your risk analysis in order to focus testing efforts and optimise testing spend.
