Test soorten software

With each difference, I would review and decide, based on the test, whether the result was a true failure or defect. Do we really need to test that code? The goal of testing software is not to find bugs or to make software better.

This goal is especially relevant to testing enterprise software with complex digital workflows. In such a case, ensuring smooth functioning, usability, compatibility, and data consistency of the software is of paramount importance due to the higher impact of any issues uncovered after a release. Customers can be impacted by the frequency of an error or undesired functionality, or by the severity of the problem.

The reason I define software testing in this way is because—as any tester will tell you— you can never find all the bugs or defects in a piece of software and you can never test every possible input into the software. For any non-trivial application. So, the idea is not to find every single possible thing that is or can go wrong, or even to verify the software against a spec—as some people like to define software testing—because both are impossible.

Oh, also if you ever find a complete spec for any application in your experience as a software developer, let me know. Instead, the focus and main idea behind software testing is to reduce the risk that the customer is greatly impacted in a negative manner when using the software. Typically this is achieved by first prioritizing what areas of the software are likely to have the biggest impact i.

When the actual functionality deviates from the desired functionality, a defect is usually logged and those defects are prioritized based on severity. Some defects get fixed, other defects are low enough impact that they are just noted and left in the system. Just like the development world has many concepts and methodologies for creating software, there are many ways to think about how to test and the field is changing all the time. Early in my career, it could be perceived as a slight or insult to call someone who worked in testing a tester; they preferred to be called QA or quality assurance professionals.

Just a year or two ago, I attended a testing conference and I made the mistake of calling someone a QA person.

They corrected me and said that tester was the preferred term. When you do black-box testing, you are only concerned with inputs and outputs. Most testing is done in this fashion because it is largely unbiased.

Real white-box testing is when you understand some of the internals of the system and perhaps have access to the actual source code , which you use to inform your testing and what you target. With white-box testing , you have at least some idea of what is going on inside the software. Oftentimes, unit testing is called white-box testing, but I disagree. Met welke data gaan we de omschreven functies testen en op wat voor manier?

Wat verwachten we als uitkomst met deze data? Uitvoeren van de test Vergelijk de daadwerkelijke uitkomst met de verwachte uitkomst om te kijken of de applicatie voldoet aan de verwachtingen. Veel voorkomende soorten van functioneel testen: Unit testing.

Deze testen worden meestal uitgevoerd door de softwareontwikkelaars zelf. Zij testen de code die ze maken op zaken als volledigheid en methode. In het kader van functioneel testen gaat het hierbij of de code goed geschreven wordt en dus functioneert. Smoke testing. Dit is een eerste test die moet aangeven of de basisfunctionaliteiten in orde zijn.

Door middel van een aantal test cases wordt gekeken of deze versie van de software stabiel is en klaar om verder ontwikkeld en getest te worden. Sanity testing. Wordt meestal na de smoke test gedaan om te kijken of alle grote en belangrijke functies van de code functioneren "zijn ze wel goed bij hun hoofd Regressie testen. Met een regressietest wordt gekeken of alle systeemonderdelen nog goed blijven functioneren nadat er wijzigingen in de software zijn aangebracht.

Integratie testen. Wanneer verschillende onderdelen van de software moeten samenwerken, moet er getest worden of deze samenwerking goed werkt.

Ook wel beta test of usability test genoemd. Generate code coverage by adding the flag --coverage. No additional setup needed. Jest can collect code coverage information from entire projects, including untested files. You can use mocked imports with the rich Mock Functions API to spy on function calls with readable test syntax. Jest is a JavaScript testing framework designed to ensure correctness of any JavaScript codebase. It allows you to write tests with an approachable, familiar and feature-rich API that gives you results quickly.

Jest is well-documented, requires little configuration and can be extended to match your requirements. You need to check if someone can easily compromise data, get access to a resource they're not supposed to. A good testing suite should try to break your app and help understand its limit.

And finally, tests are code too! So don't forget them during code review as they might be the final gate to production.

I've been in the software business for 10 years now in various roles from development to product management. After spending the last 5 years in Atlassian working on Developer Tools I now write about building software. Outside of work I'm sharpening my fathering skills with a wonderful toddler.
