3 Big Questions of Software Automation Test: Why, When, and How?

3 Big Questions of Software Automation Test: Why, When, and How?

As businesses continuously adapt to technological advancements, the need for speed and accuracy converges. Automation in testing not only enhances efficiency but also significantly reduces the potential for human error, ensuring that the final product aligns perfectly with user expectations. This blog delves into the intricacies of software test automation, a key enabler in the quest for excellence in software delivery.


Knowledge Recap

In the previous blog, we learned about test automation and how organizations can integrate it into agile testing. For this one, let’s quickly skim through the roots of automation testing. 

Test automation is conducted using testing tools to confirm the correct functioning of software according to user expectations. It involves automating the execution of test cases, during which problems are identified and addressed as they arise, whether during or after the development process.Furthermore, this form of testing is executed through specialized equipment and software that operates on programming scripts. These scripts expedite the testing process, ensuring that comprehensive coverage is achieved across all types of scenarios and various tests.

Benefits of Test Automation

  1. Seamless Accuracy and Reliability: Automated testing can ensure correct and consistent results because it reduces human errors in testing, which are very important for complex applications.
  2. Better Reporting of Tests: The automation tool creates a detailed report of the test, which gives all the key information about the application’s quality and the effectiveness of the process of testing.
  3. More Test Coverage: Automation permits the test coverage to get deep into cases that are complex, apart from being so vast, thus ensuring comprehensive application testing.
  4. Bug Detection Efficiency: Automated testing accelerates the process of finding bugs or errors, so with this acceleration, there will be a quick solution in the development cycle, which is very necessary to maintain the project’s timelines.
  5. Reuse of Test Case: Automation allows us to reuse the written test scripts for various versions of the application, increasing resources and reducing consumption of time for repetitive tests.


Test Automation Challenges

  1. Maintenance and Scalability: Test cases and scripts need to be maintained and updated after each change/update to the software; this becomes a cumbersome and resource-consuming process when the scope of automation is high.
  2. Initial Setup and Cost: To set automation up requires an initial investment in tools, training, and system integration. Although this can be considered quite hefty, it might not make sense for smaller projects.
  3. Skill Requirements: Programming skills are required for the effective management of automated testing, which makes it challenging to train a team and manage a project.
  4. Tool Limitations: While there is a range of tools available, each tool has limitations and effectiveness that could vary based on the detailed requirements and project context.


Why should companies choose automated tests?

Big 3 Questions of Test Automation: Why, When and How?

Test automation has emerged as a crucial element within software development due to the vast number of applications being used and developed daily. Under the pressure of user demands, applications must evolve rapidly, rendering manual testing inadequate. 

Organizations employ various testing methodologies to ascertain and enhance the quality of their products. Among these, regression testing is crucial for maintaining the quality of a product over time. Furthermore, organizations that lack an automated test suite would derive substantial benefits from implementing a test automation platform specifically designed for their needs.

Additionally, the adoption of automated testing processes significantly reduces organizational time and cost burdens while greatly enhancing product quality. Consequently, this growing realization is rendering manual testing increasingly ineffective. Today, an automated test suite can simulate the interactions of hundreds of virtual users with an application, a capability far beyond the reach of manual testing methods.


When should companies use automation test?

Big 3 Questions of Test Automation: Why, When and How?Considering the advantages of test automation—such as accelerating development and feature rollout, enhancing product quality, and cutting operational costs—it’s certainly worthwhile for businesses for whom these factors are critical.To transition from manual to automated testing, it is advisable to evaluate which tasks or test cases are suitable for automation and to assess the potential return on investment.Besides that, there are a few types of testing that are difficult or not preferred:

  • User Experience: focuses on the overall experience of a user while interacting with a product.
    => UX testing involves subjective assessments that depend heavily on human feelings, preferences, and experiences, which cannot be accurately replicated by automated systems. 
  • Usability Testing: evaluates how easy and intuitive an application is for users. It typically involves observing real users as they attempt to complete tasks on the product and is essential for identifying usability obstacles that could frustrate users.
    => This type of testing depends on real-time feedback and interaction from users, which automated tests cannot mimic. Observing where users struggle, the kind of mistakes they make, and where they get confused requires human observers to interpret complex human behaviors and reactions.
  • Exploratory Testing:  is an approach where testers actively explore the software without a set script or predefined test cases, relying instead on their skills and intuition to discover issues or unexpected behavior.
    => By nature, exploratory testing is spontaneous and creative, relying on the tester’s insight, experience, and intuition to guide the process. 
  • User Acceptance (UAT): is performed to determine if a system satisfies the business requirements and is ready for real-world use.
    => UAT tests whether the solution works for the user in their actual operating environment and meets their business needs.

In all these types of testing, the common limitation for automation is the inherent need for human judgment, subjective feedback, and flexible thinking, which are critical for assessing the usability and user experience of any software application.

How to decide on automation tests?

When determining which tests to automate, it is crucial to assess their importance, as not all tests can be automated. Consider prioritizing tests based on the following criteria:

  • Regression tests are the most frequently run test scenarios.
  • Tests that are labor-intensive or need to be executed repeatedly.
  • Tests are prone to human error that could result in failures.
  • Routine and tedious tests that do not vary.
  • Comprehensive tests that utilize multiple data sets.
  • Tests that are impossible to execute manually.
  • High-stakes tests that provide critical data possibly be used in legal situations.


In conclusion, test automation is increasingly crucial in the fast-paced world of software development. It significantly enhances the speed, efficiency, and accuracy of testing, ensuring software meets the high standards required by users and markets. While automation brings numerous benefits, it’s important for companies to strategically select which tests to automate to maximize their return on investment. By doing so, businesses can achieve better product quality and operational efficiency, staying competitive in a demanding technological landscape.
