The biggest challenges in API testing

The world is getting more and more connected every day. More than 35 billion independent iOT’ (internet of things) are now already connected to the internet as of 2021. As things in the digital space move at a faster rate, finding the best testing approach is becoming a big challenge, especially when it comes to new measures in test tech such as API’s. Today we’re going to look at what API testing is, and what challenges it brings to the table.

So, without any further ado, let’s dive right in.

What is API testing?

Unlike the previous era of tech, modern apps are distributed over many access points. Instead of being autonomous, multiple services are now tied together to provide a complete CX.

An API (Application Programming Interface) is the bridge that connects all the apps and code modules to the back-end systems.

Benefits of API testing

Below are some of the notable benefits of API testing:


Language independent testing

In most app testing cases, the exchange is using XML or JSON. They are language-independent and used for various dev cycles. As a result, API testing teams can perform the test while selecting any core language.

Protection for code breakage

With API testing, the dev team can remove any vulnerabilities and figure out the perfect inputs. It also helps tackle any issues with code breakage or unknown code.

Increased productivity

During the development phase, the dev team has to start many codes from scratch. However, the API designs help the dev team by providing a solid codebase. This existing code enables them to work faster and reduces work time.

We’re only scratching the surface when it comes to the pros of API testing. That being said, there are major challenges that we have to face while doing API testing.

Below are some of the most common API testing challenges.

API testing challenges

Getting access to connected systems

The goal of API is to pull data from multiple back-end systems. We can express it as a tree that extends deep and wide with each system. As a result, it is almost impossible to access key parts of the tree environments.

This problem can be minimized by emulating the resources that are inaccessible by the API itself.

Initial setup of API testing

To perform a successful API test, we must do it manually to ensure everything is working perfectly. At the same time, automated testing is needed to gauge how they perform under pressure.

As a result, we must build a testing structure to get the testing phase up and running. It’s a big challenge, not because it’s difficult to do, but because it can drain testing motivation. Whereas, getting a good structure up and running can pay off over the long run.

Parameter validation

Validating the parameter sent through the API request is a big challenge as well. The massive number of possible parameters can be quite daunting. Although automated API tools can help testers out, it is still a big challenge for the tester.
