Automating Software Testing: Benefits and Best Practices

Software testing automation is a process to test and validate software using specialized tools by following test automation frameworks.

The tools test the software to check if it meets the necessary requirements. And if it does, the software will be released for the next step or production.

The goal of automated testing in software development is to find errors, identify bottlenecks, check for missing requirements, and eventually improve software quality. The process is nothing new and has been used since around 1970.

With time and an increasing demand for software in the digital landscape, the process is now adopted widely to ensure faster production and delivery.

Understanding Software Testing Automation

Automated software testing involves testing software by using various software testing tools and frameworks without manual or human intervention.

The scope of automation is always evolving, and it is creating a fast-paced software development landscape with testing tools. These automated testing tools were limited to performing basic tasks in the beginning.

However, as the tools got more and more advanced, they became more capable. Eventually, they began enabling testers to write and perform automated testing scripts.

Now, there are many types of tools for automated test execution, such as,

Functional testing,
Non-functional testing,
Unit testing,
Smoke testing,
Performance testing,
Regression testing,
Data-driven testing, etc.

But how is automated testing different compared to manual testing? Here are some of the differences:

Automated Testing

It eliminates boredom as a QA delegates the repetitive tasks to the computer.
Automated testing is done using software testing tools and following specific frameworks and scripts.
More reliable for repetitive tasks and ensures more accuracy.
Usually less time-consuming.
Cost-effective in the long run.

Manual Testing

It can be repetitive and boring.
Manual testing is done by humans without any scripts.
Less reliable as it is prone to human error.
Very time-consuming process.
Requires a higher budget for using the process for a long time.

Thus, it shows that test automation benefits the software development lifecycle by identifying bugs early, optimizing resource utilization, and accelerating development by automating repetitive tasks.

Benefits of Automating Software Testing

Increased Test Coverage

With the help of automated QA processes, automation tests execute a large number of cases of software testing.

Improved Accuracy and Consistency

Since no manual tasks are involved, the process is more consistent and error-free, and eventually, it ensures more accuracy than the manual process.

Early Detection of Defects

One of the particular benefits of automated testing is that it helps detect various defects, such as bugs, and reduces technical risks.

Cost-Effectiveness

Related to what we stated above, detecting bugs and ensuring fewer errors makes automation a cost-effective testing process.

Enhanced Team Productivity

Automated testing benefits the team by reducing repetitive tasks and taking workload and burdens off the developers’ shoulders. As a result, the process is highly beneficial to increasing team productivity and allows the team to focus on further development.

Faster Time to Market

Automation ensures a more continuous testing process, enabling faster deployment and market delivery.

Best Practices in Automating Software Testing

To ensure the best practices for automated testing, it is essential to start by selecting suitable test cases and then evaluating them to find the right cases.

Next, prioritize the tests that validate the core functionalities and offer long-term benefits. It also includes creating reusable automated test scripts that stimulate action and interaction.

Automation best practices also involve implementing continuous integration to reduce frequent errors, identify bugs, and reduce development costs. Then, there is DevOps, which is one of the significant automated testing best practices.

It encourages companies to foster cross-team practice to break down Silos and streamline the software-delivering process. Then, monitor the test results and maintain automation suites in the following ways:

Planning a test data management approach,
Updating test cases,
Refactoring test codes,
Enhancing test coverage,
Addressing test failure,
Automate new test cases,
Documenting everything.

Choosing the Right Automation Tools

Evaluation Criteria

Evaluate the automation tools criteria by asking necessary questions.

What does the project require?
Can your team utilize the required tools or are they skilled enough to utilize them?
What is the team budget?
What are the features you are looking for?
What are the integration capabilities?

Open-Source Vs. Commercial Tools

Open-source tools are mostly free, whereas commercial tools are not. On top of that, open-source tools come with security vulnerabilities, lack stability, and offer limited features.

On the other hand, the benefits of test automation commercial tools are that they are more reliable and secure, designed to meet the needs, offer a wide range of features, and more.

However, these tools also have certain drawbacks other than the expense, such as lack of customization, limited platforms, and some even charging extra for customer support.

Some of the popular automation frameworks (open-source and commercial) are:

Selenium,
Appium,
Katalon Studio,
Cypress,
Robotium,
Watir,
JUnit,
OpenText UFT One,
Ranorex,
TestComplete, etc.

Support for Various Testing Types

The selected tools must support a wider range of testing types, such as security testing, smoke testing, ROI testing, unit testing, regression testing automation, etc.

It is also necessary to check whether the tools are compatible with the existing system and organization environment. Look for tools that offer scalability and flexibility because that will allow the tools to adapt to new changes in the software while testing.

Overcoming Common Challenges

Configuring a stable environment when initiating automation setup is one of the best ways to implement QA automation successfully.

Handle dynamic interfaces by leveraging stable locators, using more robust XPath and CSS Selectors, regulating maintenance and updates, etc. If there are flaky tests or tests that fail for no apparent reason, here is what you can do:

Identify the root cause of failure,
Repeat the test execution,
Prioritize stable tests,
Eliminate the flaky test,
Take preventive measures, etc.

Overcoming automation in software testing challenges also requires regular maintenance of test scripts, test data management and environment, and proper collaboration among the teams.

Integrating Automation into Development Processes

Implementing agile and iterative methodologies is the best way to integrate automation as it promotes adaptability and increases flexibility.

Integrating test-driven development or TDD ensures faster debugging, modular development, cross-team collaboration, clear documentation, etc.

There is also behavior-driven development or BDD, a software development approach that emphasizes user behavior based on interaction and helps cater to the target audience.

Continuous testing pipelines help automate the test execution in every stage of the cycle, while the shift-left approach identifies and resolves bugs to speed up the development process.

Feedback loops and retrospectives are also essential for automation integration as they improve team performance.
