UNITED Courses

Certified API, REST & Microservices Tester

Leverage your testing skills by focusing on API and microservices testing with a 3-day hands-on training of the most commonly used tools.

Course overview:

APIs have become mainstream with almost all applications using APIs and microservice to create scalable and maintainable software. Shift-left philosophy as well as DevOps have resulted in API testing gaining huge traction in the market. 

The United – Certified API, REST and Microservices Tester (APIU-CARMT) was created to help Testers get a grip on API and Micro services, the new API and Microservices testing methodologies and tools. The focus of this course is on APIs and microservices testing covering additional aspects of scalability, modifiability and maintainability. 

APIU-CARMT certification course is a 3-day practical, hands-on certification course with various tools being used to perform hands-on API testing on applications implementing microservices and hosted on the cloud.

Major takeaways:

➜   Understand the current trends and industry applications of application programming interfaces (APIs).
➜   Understand REST, SOAP and microservices.
➜   Understand how API testing complements UI Testing.
➜   Define a test strategy for testing of APIs.
➜   Use API test tools to automate testing of APIs.
➜   Apply data-driven testing to API testing.
➜   Use test tools to perform testing of Microservices

Best suited for:

All testers who are looking to get skilled in testing SaaS and cloud need to get certified on this. Additionally, testers who test web-based applications based on standard interfaces like REST and microservices would highly benefit from taking this course.

➜   Functional Testers
➜   Test Managers
➜   Infrastructure Managers
➜   Cloud Architects
➜   Performance Testers
