Summary

Many modern web applications use web APIs to exchange information between services. At that layer you can test what a service does without going through the user interface. There are also risks in working with web APIs that have to be tested at exactly this level. Knowing how web APIs are built and how they behave is therefore essential — and yet the field remains unfamiliar to many testers.

This course teaches the basics of web APIs. That not only lets you hold your own in conversation with the development team, it also gives you the ground to learn more about testing them. The training concentrates on testing a web API by hand, using the exploratory approach. You get to know a web API and try it out directly in hands-on exercises.

Topics covered

What is a web API?
What belongs to it? (HTTP verbs, HTTP status codes)
Why web APIs deserve a close look (from a testing point of view)
How do you interact with a web API?

FAQs

Do you also offer in-house training?

Yes — we are happy to plan your own in-house course with you.

Are the costs of a course with you covered by the Federal Employment Agency?

No, BREDEX is not certified for that.

Can I redeem an education voucher with you?

No, BREDEX is not certified for that.

Where do I find your terms and conditions?

After booking you receive a confirmation with a link to the terms and conditions. You can also find them at the very bottom of the BREDEX Academy website.

Can I book an ISTQB exam without having attended your course first?

Yes — you are welcome to sit the ISTQB exam alone.

Do you also offer the courses online?

Yes, as a rule we offer every course online or remote as well. On the BREDEX website you can see whether your course is offered online on the date you want — it is marked as an online course there. If your date is not available online, simply write to us at weiterbildung@bredex.de.

How does an online course work?

Whether it is facilitating a retrospective, a technical course or a design thinking workshop — our experts guide you remotely at the same quality. Despite the physical distance we put great weight on interaction, lively conversation and a variety of methods. You can see what that looks like in this short video.

Does the software for programming courses have to be installed beforehand for an online course?

We offer every one of our programming courses remotely as online training too — at the same quality. All you need is a device with an internet connection and, ideally, a headset and a camera.
The software a programming course normally needs (the development environment, installed language packages such as Java 8 and the like) does not have to be installed by participants beforehand.
During the course you simply open your browser again and follow our link to the virtual machine. That is a virtual computer running on a host system: a sealed-off environment in which several operating systems of an independent guest system can run side by side on one physical machine. Put simply, another (virtual) computer that you operate from your own. Nothing you do there has any effect on your own device. This way you can reach every piece of software and every tool the course needs and start programming right away — without having to take care of anything before or during the course.
