11 Test Automation Best Practices [2026]

What Are the Hurdles of Automated Testing?

Common hurdles include learning new programming languages, selecting the right tools, high initial investment, and overcoming team resistance to change.

Once you build a testing team, the next step is to know what is stopping your team from moving to automated testing. In most cases, it is the idea of learning a new programming language. Can a team learn a new programming language and implement a successful test automation project? These are the hurdles that the team has to overcome. To overcome such fears, a team should start small.

Watch this webinar to learn about enterprise-wide actionable strategies, the dos and don’ts of automation testing and DevOps tooling that will help you improve the release and test velocity.

How to Choose the Right Tools and Frameworks?

Select tools based on test requirements, language compatibility, OS support, whether open-source or commercial, and alignment with your team's expertise.

The main idea is to get your team comfortable with the tools and framework you wish to utilize. It is a fact that the choice of the automation tool has a vital role to play. The tool selected can either be open-sourced and free or commercial ones that need to be purchased but have better features and offer better support. The features associated with the tool should be in line with the test requirements of the software applications that need to be tested. It should be functional with multiple programming languages, operating systems, etc.

3. What to Automate

First and foremost, the team has to prioritize which tests to automate. Just because you can automate tests, it doesn’t mean it should be applied to everything. It’s unnecessary to automate all tests. Many tests are better off being done manually. Automating complex and less often used tests is a definite failure and isn’t worth the team’s effort. In addition, create a list of the browsers and devices that will be essential to your particular test suite.

How to Allocate and Divide the Effort for Automation?

Divide testing tasks based on team members' skills, expertise in scripting languages, test schedule requirements, and team size for optimal efficiency.

Usually, the creation of different tests reflects QA engineers' skill levels. Therefore, it is essential to identify each team member’s experience and skills. Then, divide the testing efforts based on the team member’s skill set. For example, writing test scripts requires an in-depth knowledge of scripting languages. Thus, to perform these tasks, you should have QA engineers that know the script language provided by the automated testing tool. The efficiency of a test automation plan depends on the correct task allocations to personnel based on the test schedule, the expertise of the professionals, and the testing team size.

Why Should You Divide into Smaller Functional Modules?

Smaller modules improve test coverage tracking, simplify defect localization, and make writing and maintaining test scripts easier for testers.

Creating modules makes it easier for the project managers to track test coverage efficiently and understand the exact location of the defect or errors. It is also easier for testers to write test scripts for smaller modules.

Why Use a Custom Test Environment?

Custom test environments replicate production settings accurately, ensuring reliable test results that reflect real-world application behavior and configurations.

Creating an effective customized test environment can only be done by the exact replication of the production environment. Thus the test environment needs to include test automation systems and tools which are used in the development of software with customized configurations.

Why Should You Test Early and With Higher Frequency?

Early and frequent testing reduces defect turnaround time, catches bugs sooner in the development cycle, and improves overall software accuracy.

Testing early and frequently facilitates a significant reduction in the defect or error turn-around time. In addition, frequent testing throughout the different phases of software development also enables it to function with greater accuracy.

What Are the Metrics for Test Result Analysis?

Key metrics include test coverage, execution time, pass/fail rates, defect detection rate, and ROI to monitor quality objectives across development cycles.

Getting the right metrics to assess and monitor the quality objectives throughout the different software development cycles is another crucial aspect of an effective software test automation plan.

Why Is Bug Reporting Important?

Quality bug reporting with clear, detailed information directly reduces defect turnaround time and helps development teams fix issues faster.

There is a direct relation between the quality of bug reporting done and the turn-around time. In addition, the availability of clear, detailed, and precise information on the errors present in the software helps to eliminate them faster.

Why Should Code Be Comment Heavy?

Detailed comments help team collaboration, make code understandable for co-workers and your future self, especially in complex automation sections.

Most of the time, you will not be the only one working on automation. So help your co-workers and yourself by keeping good comments on your code. People are not mind readers and will not understand your thought process. So always add very detailed comments in incredibly confusing sections for your co-workers’ benefit but also your future self!

Why Is Code Reusability Important?

Code reusability saves time by eliminating redundant element finding. Create elements once and reuse them across all test actions efficiently.

One of the most common actions in automation is finding the element for every action like click, enter, etc. Code reusability is essential since finding the same element for every action is a waste of time. Instead, create it once and then reuse the same everywhere required.

The delivery of a quality software or application depends on the effectiveness and efficiency of its software testing plan. Therefore, test automation can only help achieve quality software and reduce time-to-market when it follows certain best practices. However, it’s essential to understand that every enterprise has different requirements. Therefore, study these practices and implement them to best suit the software, the business, and the users.
