K6 Grpc Testing

Provide confidence through repeatable automated tests

What you'll learn

How to tests gRPC Web-Services using K6.

How to Automate gRPC Web & Micro Services using k6

How to use the specific proto type "any" and "oneof" in our k6 tests.

How to create a framework to host all of your k6 gRPC tests.

Automate your k6 gRPC tests using Kubernetes cron job?

Automate your gRPC tests using Jenkins.

Take a deep dive into how spike, load, soak and smoke test run inside of gRPC

Start bullet proofing your tests so that you capture all exceptions, not surfaced by K6 and bring them back into the K6 fold

Learn how to share a single gRPC connection over all iterations of a spike test

Learn how to share a single gRPC connection per user over a spike test

Learn how to data drive your smoke tests

Learn how to randomise your parameters in within a spike test

Learn the theory of why having an automated process for smoke testing your gRPC test affords confidence, repeatability amongst other great benefits.

Requirements

General programming knowledge would be handy although I will step through how to install and work the required software, line by line.

This course is run using a Mac book pro, if you want to use windows, I recommend git bash, linux sub system or converting part relating to the framework into a windows related scripts.

Description

In this course we take a look at what K6 has to offer the world of automation for gRPC tests.  I also explore other technologies that we can use to enhance this product into a framework that we can use to add more functionality to our arsenal.  What do you want from a gRPC test framework?:A counter of successes and failures, with a no colour option.  Negative and positive test pass as intended.Exit framework on first tests failure.Dependant gRPC requests shown as part of your systemData driven gRPC testsThe ability to run your gRPC framework on kubernetes or Jenkins.What do you want from your scaled up gRPC performance tests?:The ability to have reliable tests that will report all errors and in turn give a true representation of your gRPC reliability.The ability make these test simulate randomness of data input. The option to share connection on a per user basis or over all iterations.Self recovering tests that try to recover on failureWhat do you want from your gRPC Micro Services?: The ability to have confidence that a change has not broken anything.The ability to say to managers in a matter of minutes that it works as it should. the ability to work efficiently and independently from the consuming/producing team.The ability to run tests as part of your CI/CD system The ability to run tests at  a scheduled time of day. If the answer is yes to any of the above then this is the course for you.  Also look a the rarer proto types such as "any" and "typeOf".
