TestOps in Software Testing: What is its Role?

Introduction

Before diving into the TestOps approach, let’s introduce the DevOps first. With the widespread adoption of agile methodologies and DevOps represents a paradigm shift in software development, promoting collaboration, automation, and a continuous feedback loop.

As teams embrace continuous integration (CI) and continuous delivery (CD) pipelines to drive software development through a process of building, testing, and deploying code automatically, this presents a unique challenge: meeting the ever-growing demand to deliver software quickly while maintaining high-quality standards.

In this particular context, software testing is undergoing evolution to keep pace with the accelerated development methodologies, underscoring the critical need for adopting fresh testing approaches, including:

• Quality Engineering: It refers to the systematic approach of ensuring software quality throughout the entire software development lifecycle, where testing happens throughout the development process, not just at the end. This approach advocates not only testing software for defects but also proactively preventing them through rigorous testing processes. Additionally, it promotes a culture of quality where everyone is responsible for delivering a high-quality software product.
• Shift-Left and Shift-Right Testing: Shift-left testing focuses on detecting and preventing defects as early as possible. Often through techniques like unit testing and code reviews. Shift-right testing, on the other hand, emphasizes monitoring software in real-world environments to gather feedback and improve quality continuously. These approaches complement Quality Engineering by integrating testing more seamlessly into the development process.
• Test automation: It involves using software tools and frameworks to automate the execution of tests. That allows the rapid and efficient validation of software functionality, performance, and reliability.
  Continuous Testing: It is the practice of executing automated tests continuously throughout the software delivery pipeline. It’s an extension of the principles of Continuous Integration (CI) and Continuous Delivery (CD). It aims to provide rapid and continuous feedback on the quality of software builds.

As evident, there is a significant emphasis on test automation. It’s widely acknowledged that test automation enables faster execution of test cases, ultimately saving time and effort compared to manual testing. While initial setup costs may be incurred, test automation can lead to long-term cost savings by reducing the need for manual testing resources as illustrated in the ROI chart below:

DevOps & Testing

As teams place greater emphasis on ensuring software quality throughout the entire software development lifecycle through continuous and automated methods, it’s natural that various types of tests are conducted to ensure compliance with both functional and non-functional requirements.

With DevOps, various common types of tests are typically employed to ensure the quality and reliability of the software. These include (though not exclusively limited to):

• Functional Testing: Verifies that individual functions or features of the software behave as expected according to the specified requirements.
• End-to-End (E2E) Testing: Tests the entire software application from start to finish. The goal is to simulate real user scenarios and ensure seamless operation across all components.
• Integration Testing: Validates the interactions between different components or modules of the software to ensure they function correctly when integrated.
• API Testing: Verifies the functionality, reliability, and security of application programming interfaces (APIs). The goal is to ensure they meet requirements and can effectively communicate with other software components.
• Performance Testing: Assesses the responsiveness, scalability, and stability of the software under varying levels of workload. The goal is to ensure that it meets performance expectations.

Striking a balance between efficiency and quality

As an increasing number of these test types are adopted to validate various aspects of the application under test, the number of different automated tools and automated tests tends to grow exponentially. Remember that, in this context, individuals in different roles (including developers, SDETs, testers, among others) will employ various automated testing tools at different stages of the software development lifecycle and within the DevOps pipeline.

It’s crucial to emphasize that implementing test automation on a large scale creates a paradox. While automating more tests can boost efficiency, it also requires dedicating more time and effort to orchestrating the execution, prioritizing, and maintaining those tests.

This requires teams to identify methods that help optimize testing efficiency without compromising quality.

TestOps serves as a valuable ally in supporting these teams in achieving this objective.

TestOps at a Glance

TestOps is an emerging approach that combines various testing methodologies with DevOps principles to streamline and improve testing processes. Its core objective is to enhance the efficiency, coverage, and effectiveness of testing activities by closely integrating and coordinating them with the development process.

TestOps encompasses several stages, as detailed below:

• Planning: Planning what to test, how to test and who should test.
• Management: Management of the team, the tools, test environments and the test themselves.
• Control: Implementing governance and change management practices alongside standardizing the testing processes.
• Metrics and insights: Monitoring and measuring key testing and quality metrics to assess the efficiency of the testing efforts.

TestOps is built upon several foundational pillars that facilitate a smooth transition from traditional testing to a more agile, collaborative, and efficient approach, as outlined below:

• Test automation: It involves using software tools and frameworks to automate the execution of tests, allowing for the rapid and efficient validation of software functionality, performance, and reliability. It aims to facilitate the early discovery of bugs, increase test coverage, speed up testing cycles, and improve overall software quality. Through automated tests, repetitive and time-consuming manual testing tasks are replaced, enabling testing teams to devote their efforts to tackling more complex and critical testing challenges.
• Continuous Testing: It is the practice of executing automated tests continuously throughout the software delivery pipeline. It is an extension of the principles of Continuous Integration (CI) and Continuous Delivery (CD), aiming to provide rapid and continuous feedback on the quality of software builds. By running automated tests continuously, developers and testers receive immediate feedback on the impact of their code changes, enabling them to address issues promptly and iterate rapidly.
• Test Environment Management: It involves the systematic management of provisioning, configuration, monitoring, versioning, and collaboration to ensure the availability, reliability, and efficiency of testing environments across the software development lifecycle. This process facilitates the creation of self-service environments where teams can spin up environments on demand. It ensures that testers have representative environments that mirror production as closely as possible to conduct their tests.
• Test Data Management: It refers to the process of creating, managing, and provisioning high-quality test data to ensure that automated tests have access to the data they need in a timely, realistic, and compliant way. This process is essential for achieving comprehensive test coverage and maintaining the quality and speed of software delivery.
• Test Orchestration: It involves automating the execution of tests, coordinating test environments, managing test data, and facilitating communication among different teams involved in testing.
• Collaboration: TestOps promotes a cultural shift where testing is seen as a shared responsibility across the entire software delivery pipeline rather than being isolated to a dedicated testing team.

Considering this, here are several advantages of embracing TestOps:

• Improved software quality: TestOps ensures that testing is integrated throughout the development lifecycle, not just at the end. This leads to more comprehensive testing and fewer bugs escaping into production.
• Faster release cycles: By automating tests and streamlining the testing process, TestOps can help teams release software more frequently.
  Reduced costs: By automating tests and catching bugs early, TestOps can help to reduce the overall cost of software development.
• Enhanced collaboration: TestOps fosters closer collaboration between development and testing teams, which can improve communication and break down silos.

Embracing Gravity to test the right things with less effort

Gravity leads the way in the Quality Intelligence space by providing a unified platform tailored to support teams that adopt TestOps. It enables teams to monitor and leverage raw data from both testing and production environments, allowing them to optimize testing efforts and focus on the most critical aspects of the application.

Gravity’s primary function is to produce “Quality Intelligence” by processing the ingested data through ML algorithms. This involves translating raw data into meaningful insights using techniques such as pattern recognition, trend and correlation analysis, anomaly and outlier detection, and more.

Gravity sets itself apart from other tools in this space by not only ingesting and analyzing testing data from tools used in pre-production testing environments but also by delving into production usage through the ingestion of Real User Monitoring (RUM) data.

Traditional RUM tools are crafted for different purposes rather than to generate quality intelligence. While they serve a range of teams, including Developers, Performance Engineers, Site Reliability Engineers, and DevOps Engineers, their capabilities may not align perfectly with testing needs, let alone generating Quality Intelligence.

Gravity’s ability to monitor production and testing environments allows it to conduct a comprehensive test gap analysis. By comparing the paths taken by real user interactions in live production with the tests executed in testing environments, Gravity generates insights to enable testing teams to spot gaps in coverage, identify features that are either over-tested or under-tested, and recognize redundant testing efforts in less critical areas.

This enables data-driven test case prioritization, focusing test coverage on high-impact areas that directly affect the end-user experience. By bridging assumptions with insights extracted from testing and production environments, Gravity helps optimize the testing efforts efficiency for relevant coverage.
