The main benefit of developing a test automation strategy is it provides a clear plan of action for implementing automation in a structured and effective way. This structured approach leads to several key advantages, including faster detection of bugs, improved collaboration, and shorter time to market.
Faster detection of bugs
A well-defined test automation strategy ensures that testing processes are streamlined and automated. Automated tests can be executed more quickly than manual tests, allowing for the rapid identification of bugs and issues in the software.
Automation enables testing to occur continuously throughout the software development lifecycle, from the early stages of development to post-release. This early and consistent testing helps catch bugs at their inception, reducing the cost and effort required to fix them.
An automation strategy establishes clear objectives and roles for team members involved in testing. It defines responsibilities, processes, and communication channels. This clarity fosters better collaboration among developers, testers, and other stakeholders.
Automated tests provide consistent and repeatable results, reducing the ambiguity and disputes that can arise from human interpretation. Team members then have complete trust in the test results and can focus on resolving identified issues.
A test automation strategy defines a process for communicating goals and plans to stakeholders. This sparks important discussions around new proofs-of-concept or technologies to implement within your organization.
Shorter time to market
Automated tests offer rapid feedback on the quality of the software, enabling timely adjustments and corrections. This leads to a more efficient development process with shorter feedback loops.
With automated testing, you can perform regression testing swiftly, ensuring that new features or changes don't introduce new defects. This accelerates the release cycle and allows for more frequent product releases.
Shortening the time to market is crucial in today's fast-paced software development landscape. Organizations that can release high-quality software faster gain a competitive edge and meet customer expectations more effectively.
The primary drivers for test automation include reducing risk, cutting costs, and enhancing execution.
Automation minimizes the risk of error by executing tests consistently and thoroughly, enhancing test coverage, and enabling early bug detection. When software isn’t tested properly, it can lead to system failures, which have catastrophic consequences. Earlier this year, a technical issue caused the Bank of England payments system to fail for six hours. This disruption impacted millions of transactions and prevented homebuyers from finalizing property purchases, imposing additional administrative burdens on solicitors and conveyancers.
Automation boosts efficiency and reduces labor costs, resulting in lower overall testing expenditure. In the short term, investing in automation can help your organization operate more efficiently and with fewer overheads while making better use of your existing resources. In the long term, your organization will be better positioned for economic growth.
Lastly, automation enables faster test execution, integration into CI/CD pipelines for continuous testing, and scalability to handle larger and more complex projects, expediting the software development process.
Once you are sold on the benefits of test automation and want to start automating, the next step is to figure out how.
During the automation adoption phase, challenges are common in different testing stages, so having a strategy in place is essential. Transitioning from manual testing to automated testing without a clear strategy can result in potential issues for your software development and testing process. Here are some of the consequences and challenges you might encounter without an automated testing strategy:
Testing with an automated approach is more efficient, consistent, and comprehensive. It provides rapid feedback, facilitates integration with development and deployment processes, and helps identify and address issues early in the software development lifecycle. While manual testing still plays a role in exploratory testing and usability testing, automation significantly enhances the testing process.
The test automation life cycle is a structured process that outlines the stages and steps involved in planning, designing, developing, and maintaining automated tests. It provides a roadmap for creating and managing automated test suites.
The test automation life cycle consists of six stages, including determining the scope of test automation, selecting the right tool, creating a test plan and strategy, setting up the test environment, developing and executing automation test scripts, and generating and analyzing test results.
In most cases, automation will encompass various application types, including web-based, desktop-based, and mobile. Ensure you select a test automation tool that meets all your automation requirements.
You should also outline which kinds of tests you’re looking to automate. Unit and integration testing are usually an integrated part of development practices and happen earlier than other testing practices. Still, there is a long list of other test activities that are ripe for automation.
The most suitable test types for automation are:
We have compiled a checklist of eleven areas to focus on when initiating automation or optimizing the current automation process.
This checklist presents a comprehensive approach to creating a test automation strategy, outlining key phases in the automation test life cycle and essential considerations for successful implementation.
Selecting the right tool defines the success of your test automation strategy and will make or break your test automation project. For this reason, it’s the first step in this checklist.
Every organization is unique, with varying people, processes, and technologies. Each QA team faces different challenges while working with various applications in diverse environments. Therefore, aligning tool requirements with these setups is crucial.
Consider costs, application support, and usability when determining the right tool. Shortlist tools that meet your specific requirements.
Defining a project’s scope from an automation perspective involves setting timelines and milestones for each project sprint.
In this stage, you clearly define which tests to automate and which to keep doing manually. Not all test cases can or should be automated. Utilize the 80/20 rule to prioritize tests, concentrating on repetitive and mission-critical scenarios.
When choosing a test automation approach, consider three areas: Processes, technology, and roles.
Define structured processes for developing automated test cases, maintaining them, and analyzing their results. Select appropriate tools and technologies that align with the applications being automated.
Identify the types of tests suitable for automation, encompassing functional, performance, regression, and cross-browser testing. Define the roles and responsibilities of team members, designating roles like Automation Lead, Automation Engineer, and Automation Architect.
To measure the success of test automation, you should set clear objectives that align with your business goals. These objectives should be ambitious but realistic.
Common objectives in test automation are:
Risk analysis is an essential aspect of project planning, particularly within automation.
This analysis involves creating a list of identifiable risks with the following details:
A stable and predictable test environment is essential for generating reliable automation results. This environment should closely replicate production environments to reflect what end users will experience.
Consider the following aspects related to test environments:
An execution plan should outline the day-to-day tasks and procedures related to automation.
Select test cases for automation based on the criteria defined in part 2 of this checklist. Before any automated test cases are added to your regression suite, they should be run and verified multiple times to ensure they run as expected. False failures are time-consuming, so test cases must be robust and reliable.
A consistent test naming convention is a simple yet impactful way to create an effective testing framework.
Here’s what a test naming convention should contain:
In a release pipeline, regardless of its complexity and maturity, there is a point when a team needs to decide whether to release a build or not.
Parts of this decision-making can be automated, while others require a human touch, so the final release decision will often be based on a combination of computed results and manual inspection.
Establish clear criteria for passing, such as ensuring that all automated regression tests pass and evaluating application test logs. Whatever the criteria look like in your business, it needs to be clearly defined.
Having a plan for analyzing failing test cases and taking necessary actions is a crucial, yet sometimes overlooked, part of a test automation strategy.
The time it takes from when a tester is notified of a failing test case until the fix is described, understood, and accepted in the development backlog, is usually much longer than teams anticipate. Having a well-defined process for this can save a lot of time and frustration for a development team.
Finally, once you’ve made a draft of a test automation strategy, make sure to have it reviewed and approved by all members of the involved development team.
Foster a culture of continuous learning and improvement by embracing feedback from stakeholders, peers, and team members. Lessons learned during software automation should be captured and documented for future reference. Continuously enhance your test automation strategy based on these insights.
