AnsibleĪnsible is the simplest way to automate apps and IT infrastructure. Dockerĭocker Engine enables containerized applications to run anywhere consistently on any infrastructure, solving “dependency hell” for developers and operations teams, and eliminating the “it works on my laptop!” problem. It is also more flexible and powerful in many ways than modern tools such as k6, which supports tests written in Javascript, but not the full Node/NPM ecosystem.Īs the next three layers require more setup than would make sense to outline here, we will look at them as a group and provide code examples. For our testing we are able to use Javascript libraries, such as the AWS SDK, within our tests, which makes this much more flexible than traditional DSL based solutions.
This full language support makes this a very powerful solution. You will notice we used were able to use language features such as arrays, loops and functions. Here is an example of a simple puppeteer script, which goes to and has a conversation with the bot then takes a screenshot: You can even use a browser plugin such as Puppeteer Recorder to record website interactions and save them as a Puppeteer script! Functional testing doesn't get much easier. Any Javascript library can be imported, making it incredibly powerful for interacting with Cloud providers via their SDK's. Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium. The core tool we are using is Puppeteer, a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Lets look at how we put this together Puppeteer
Accurately simulate real browser based traffic, downloading the whole app and all remote assets.Holistically test and tune the entire platform, not just the parts you write tests for.Rather than writing something ourselves, we assembled a rag-tag crew of existing tools designed for other tasks, to put together a rough-around-the-edges but extremely useful solution. Ever wished you could perform load testing against your infrastructure with an army of instances running actual web browsers?ĭue to the shortcomings of traditional load testing tools for emulating actual real world traffic, we created a solution to do just that.
