Agile Practitioners Conference

When we're talking about testing APIs, we usually think about the results as either working or not.
But APIs are like windows into our system, and sometimes, these windows are open too much. When that happens, they might expose more information than they need. There is such thing as Too Much Information with APIs.

And that's the topic of my next video.

Enjoy!

The API Series - TMI In this series, I'm talking about APIs and API testing. In this one, I talk about APIs that expose too much. And as testers, we need to make sure they don't ...

APIs are complex. Testing them is complexer. Yes, you it's a word.
Since REST APIs are based on HTTP and HTTP is based on text, you can play with what you send to see if the system can handle it.

Let's take white space for example. If you're sending JSON or XML, whitespace shouldn't matter. As long as the right non-space-y characters are in order, the server will be able to read it, right?

There's a hidden assumption (that most of time is true, that's why it's tricky). Most frameworks you use in the back-end will do the transformation from JSON to objects for you. That means they handle the "ignore the white space for you". In special cases, the developers will build the white-space filtering.

Most of the time it works. But bugs can happen. Now, what is the risk of that happening?

In the first case - low, in the second higher. The lesson is that you need to know how things are built, before deciding how to test and what.

And I made this video, on how else you can play with input data. Also visible characters.

Enjoy.
