Managing your dependencies with Test Stacks
Every Testery Test Run has a Test Stack. A Test Stack is a collection of operating systems and softwares to enable your Test Framework to run.
You never need to specify a Test Stack - if you don't provide one, a default stack will be selected for you. However, you have the ability to control the versions of Node.js and Chrome that your tests will run against by providing a testery.yml file in your source repository.
For example, a Cypress run will be assigned by default to the
node-chrome.114-java.17-nodejs.16test stack. This uses Node.js 16 and Chrome 114.
If you wanted to test your code against Chrome 113, you would provide the following in your testery.yml file.
One benefit of this approach is allowing you to test new versions of dependencies on a branch. Testery will respect the testery.yml file in your branch, allowing you to fix issues on your branch, while using the default Test Stack on your
