Create Custom Robot Framework Libraries

Share DevOps

Robot Framework supports numerous libraries which can be used out-of-the-box. But what if we need functionality which is custom to our application? In that case, we can write our own custom library. In this post, we will take a look at how we can share keywords between Test Suites and how we can create our own custom Robot Framework library.

1. Introduction

In our previous posts Automated Acceptance Testing With Robot Framework and How to Write Data Driven Tests With Robot Framework, we learned the basics of Robot Framework. We also learned how to write keywords in order to reuse commonly used functionality between test cases. All of this remained in one Test Suite, but what if you have created keywords which you also want to use in other Test Suites? We will explain how to make use of resource files and how to create custom Robot Framework Python libraries in order to share common keywords between Test Suites.
