This post will walk you through setting up REST Assured Schema Validation for both JSON and XML. Not familiar with schema validation? It basically ensures that the JSON or XML response that you get back from an endpoint matches…

Intellij through Fiddler - Title banner

Running Intellij traffic through Fiddler

By | Automation | One Comment

I recently ran into a need to capture HTTP traffic directly from my Intellij code (i.e. running in the JVM). I released I didn’t know how to capture Intellij through Fiddler. I.e. the http traffic that my application was generating. Even though I am quite familiar with using Fiddler, I did find this took a while to get working. So hopefully someone else benefits from this post on Intellij through Fiddler…

Specification Re-use in Rest-Assured with ResponseSpecBuilder and RequestSpecBuilder

By | Automation, Rest Assured | 10 Comments

When you are writing tests against your API in Rest-Assured you might have some common expected results that you want to check every single time that you call the API.

Going Further with Rest-Assured – Part 2: Parameterised Testing with JUnitParams

By | Automation, Rest Assured | 7 Comments

In part 1 of this series on Going Further with Rest-Assured, we looked at creating classes for our test data within our test code and then saw how we can put that data into a Java Map. We also took some example JSON and used Rest-Assured to create another Map of that data, so that we can compare the two. This post will follow on directly from the last one…

Going Further with Rest-Assured – Part 1: Writing and Using Test Data in your Framework

By | Automation, Rest Assured | 5 Comments

In the previous blog post we looked at how we can extract data from an API call directly into our tests using Rest-Assured and had a look at a couple of basic tests that we could execute against that data. One small issue with the previous post is that we did not have an actual API that we could use (unless you happened to have access to one), but I…

Getting up and Running with Rest-Assured

By | Automation, Rest Assured | 12 Comments

Testing APIs directly is becoming a bigger trend in the Test Automation world. A great open-source Java library that I have been using for this testing, with great success, is Rest-Assured. In this blog post, I am going to cover everything that you need to get up and running quickly with Rest-Assured. So just what exactly is Rest-Assured? Rest-Assured is an open-source Java Domain-Specific Language (DSL). It eliminates the requirement…
