Unravelling the Best Practices for DevOps Testing Strategy

With time progressing, technology is transforming at a lightning speed to make the software development process much simpler, faster, qualitative and convenient. Technologies like machine learning and AI are being utilised in several ways, not only to process qualitative and faster data but also to process predictive data. Having said that, the software development lifecycle has also evolved extensively since the last decade. Till date agile is the go to development process used by most of the development team, but since the introduction of DevOps, teams are either opting for Agile+DevOps or even implementing only the DevOps methodology. The basic difference between Agile and DevOps is that Agile refers to an iterative approach which focuses on collaboration, customer feedback and rapid releases while DevOps brings the development and the operations team together to manage the end to end engineering process. DevOps, especially in the area of testing products, brought a paradigm shift! In this blog, we will dig deeper into the DevOps testing strategies and understand how it contributes as the best testing strategy for Software Development Life Cycle.

What is DevOps ?

Setting the base by ensuring collaboration and Agile — DevOps approach to inculcate ownership throughout the teams

The goal of most DevOps projects is to automate as many manual processes as possible. These manual processes do offer roadblocks in speedy deployment. This is caused by the lack of shared ownership of the end product which is contrary to the basic agile process where the cross functional agile teams are equally responsible for the quality of the product or the success of the project. This causes the agile DevOps team to perform testing by the entire team, be it developers, testers or operations team. In the DevOps model, testing is done continuously, at the earlier stages of development lifecycle, often and even after the applications are in production.

The goal of every DevOps strategy is to build, test and release softwares faster and frequently. In an organisation you might get these two scenarios, where either you start fresh where the coding culture or development pipeline is not yet established or where the development or testing practices are already established.

Set Up a Continuous Delivery Pipeline

Using Workflow Visualization tools

There are several ways to get a handle over the current state of your development process by using workflow visualization tools like business process maps and flow charts to break down and understand the current delivery process and extract its flaws and roadblocks. One Of the simplest visual process management tools is the Kanban Board.

Helps the team to improve workflows through performance indicators

The kanban board, as shown in the image above , is just like sticky notes that depicts the project status, progress, and other issues. The value that it adds in your DevOps pipeline is that it indicates the progress and the bottlenecks in your DevOps roadmap which encourages the team to improve the workflow. It highlights the bottlenecks in the workflow that cause the work to slow down or impact the performance indicators that the entire DevOps team (from testing to development to operations) had mutually agreed on.

Improves collaboration and encourages the Dev and Ops team to follow single workflow

It also helps the Development and Operations team to work in collaboration. It helps them to avoid duplicate work and optimise the company’s release management process, in the future you will likely see an evolution of the two teams merging into one single team with a single workflow that includes both the Development and the Operations activities.

Focus on Continuous Testing

  • Continuous Development;
  • Continuous Integration (CI);
  • Continuous Delivery (CD); and
  • Continuous Monitoring

Best Practices for Continuous Testing

Automate as many tests as you can

As shown in the image above, you can use this figure as a Test Automation Pyramid for your DevOps testing strategy. The base or the first step is made up of Unit tests, this can be a strategy if the developers are integrating the code into a shared repository several times a day. This involves running unit tests or component tests and a variety of acceptance and integration test cases are executed on every check-in (application update).

Use Pair Testing on Tests you do not Automate
