Brain made of computer circuits and binary code A Simpler Way of Using Machine Learning to Shift Testing Left

The advantages of shifting left and testing as early as possible are obvious. But as you automate more testing, the test suite grows larger and larger, and it takes longer and longer to run. Instead, just automate the process of finding the right set of tests to run. The key to that is machine learning. This isn't AI bots finding bugs autonomously without creating tests; this is a different way to use machine learning, and it’s far simpler.

Pyramid in Egypt Inverting the Test Automation Pyramid

A growing company was tasked to develop a test automation program from scratch, change its coding practices, and build a continuous testing toolchain. Martin Ivison details how they did it, including realizing that implementing the traditional test pyramid wasn't going to work—it would have to be turned upside down. They found out that small is beautiful, cheap is good, and cultural change matters.

A move to DevOps creates an opportunity to shift the testing process to the left. But what if you went further? DevOps supports continuous testing, so you can advocate for a constant focus on quality, with testing permeating the entire software development process. Here's how you can actually have a faster testing process when the software is tested throughout the lifecycle, by developers, testers, and automation alike.

Before and After You Say ‘I Do’ to Docker

Docker is the most popular containerized solution being used in the software industry for development. However, implementation can get complicated, tricky, and unmaintainable if all you understand is the record-and-playback features or think it is the same as using a virtual machine.

For applications that have fully integrated service middleware, application servers, and backend databases, validation and verification of the entire application ecosystem is critical and complex. The challenge of testing these types of systems is compounded when each integrated application or component is developed by a different team or third-party vendor. Furthermore, application teams with diverse development practices generally require quick responses to system validation checks.

Large-Scale DevSecOps: Bringing Security Confidence to Chaotic Development
Slideshow

Implementing application security (AppSec) programs on a large scale can often seem chaotic and unwieldy. Without the proper knowledge to implement robust AppSec tools, DevSecOps on a large scale can be overwhelming.

Max Saperstone tells the story of how a health care company striving to get to continuous releases built up their automation to secure confidence in regular releases. Initially, as no test automation existed, Max was able to take an opportunity for greenfield test automation and, in the span of twelve months, develop over two thousand test cases. A pipeline was created to verify the integrity of the automated tests and build Docker containers for simplified test execution. These containers could be easily reused by developers and the DevOps team to verify the application. Join Max as he walks through the feedback loop that was created to allow application verification to go from hours to minutes. Max will share his choices of BDD tooling, integrated with WebDriver solutions, to verify the state of web and mobile applications.
