Course Description

In today’s digital landscape, APIs are integral, serving as the connectors that enable different software systems to communicate and interact. They’re essential for the smooth functioning of everything from web applications to mobile apps. However, ensuring these APIs work correctly and efficiently is a critical task – and that’s precisely where API testing steps in.

API testing is crucial to ensure that these vital interactions happen smoothly and securely. But let’s face it, manual API testing can be a real challenge. It’s time-consuming, prone to human error, and struggles to keep up with the rapid pace of development and deployment in today’s agile environments.

That’s where API Test Automation shines. It allows teams to test APIs quickly, accurately, and efficiently, giving them the confidence to deploy their apps knowing that they’ll work as expected. And the best part? You can be the one to provide this invaluable service to your team.

This course, “Mastering API Test Automation using TypeScript“, is designed to equip you with the skills and knowledge you need to become an expert in API Test Automation. We’ll start with the basics and work our way up to advanced techniques, with plenty of hands-on experience along the way.

Here’s what you’ll learn:

  • Project overview and tech stack familiarization

  • Setup and installation of necessary tools and frameworks

  • Proof of concept using different HTTP methods

  • Building and improving API tests on a real project

  • Scaling tests by implementing a testing framework

  • Implementing authentication in the test framework

  • Advanced topics like file uploads, utility files, reports, and CI integration with Jenkins

  • Best practices and tips for successful API test automation

By the end of this course, you’ll be able to confidently build scalable API test automation solutions, making you an invaluable asset to your team and paving the way for success in your career. So why wait?

I didn't need this but had to complete it to get the certificate. Also repl.it doesn't let you start coding, or at least the site I ended up on didn't
