Good software sometimes seems to work like magic. Until suddenly, it doesn't. Buttons don't respond, something loads just a little too slowly, or a feature quits unexpectedly. That is exactly why we take testing seriously at Tible.

The testing levels

An application consists of more separate components than you might think. That is why at Tible, we test at different levels:

• Integration testing: We test the software to see if everything works together. In this phase, we often spot bugs that arise when different components interact.
• Regression testing: After implementing changes to the software, we run a regression test. This checks if everything that worked previously still functions correctly.
• Unit testing: During unit testing, we test individual pieces of code (units). This way, you know immediately if a change causes any unwanted surprises.
• Functional testing: Does the software do what it's supposed to? We test based on scenarios and use cases to ensure the software operates correctly.

More than just working software

Software shouldn't just work quickly, but also handle sensitive data securely and feel logical to the people using it. That is why at Tible, we look beyond just the code.

We test how stable *and* fast an application remains under various conditions, actively hunt for potential security risks, and involve users to see if the software actually does what it needs to do in practice.

Finally, we scrutinize usability, because ease of use is always a requirement for our software.

Testing in practice

Testing at Tible never gets stuck in complicated theory or models. We want to know the real status of the software and processes, where the risks lie, and what is needed to take the next step. We do this with practical audits, sharp analyses, and advice that teams can get to work with immediately.

ISO 27001 certification for KnowL: We supported KnowL with the renewal of their ISO 27001 certification. In a short time, we mapped out the current situation using interviews, assessments, and a targeted audit. The outcome was not an abstract judgment, but a clear overview of the compliance status, with concrete improvement points and a realistic plan towards recertification.

Code review for Houthoff Buruma: For Houthoff Buruma, we performed an independent technical code review of the existing website. We analyzed the front- and backend on code quality, security risks, performance, and maintainability. We bundled the findings in a clear report with distinct priorities, allowing for targeted improvements. This provided confidence in the technical basis and ensured a solid foundation for future digital developments.
