The Value of Automated Testing and the Evolution of SDET Appreciation

Software development has come a long way over the past few decades, and so has the field of software testing. In today’s fast-paced and dynamic technological landscape, the role of Software Development Engineers in Test (SDETs) has evolved significantly. While SDETs were once highly appreciated for their manual testing skills, the rise of automated testing has shifted the focus towards a more balanced combination of technical and testing abilities. In this article, we will explore the value of automatic testing and why SDETs may not receive the same level of appreciation as they did decades ago.

The Value of Automated Testing

Automated testing has become a cornerstone of modern software development practices, and for good reason. Here are some key benefits of automated testing:

  1. Speed and Efficiency: Automated tests can execute much faster than their manual counterparts. They can run hundreds or even thousands of test cases in a matter of minutes, allowing for rapid feedback and faster development cycles.
  2. Consistency: Automated tests perform the same actions and checks consistently every time they run. This eliminates human errors and ensures that all test cases are executed in a standardized manner.
  3. Reusability: Test automation allows for the creation of reusable test scripts, which can be applied to different parts of the application or across multiple projects. This saves time and effort in the long run.
  4. Regression Testing: Automated tests are ideal for regression testing, ensuring that new code changes do not introduce new defects or break existing functionality.
  5. Continuous Integration and Continuous Delivery (CI/CD): Automated tests are a critical component of CI/CD pipelines, where they help validate code changes and ensure that only reliable, bug-free code is deployed to production.
  6. Scalability: As software projects grow in complexity, manual testing becomes increasingly impractical. Automated tests can easily scale to handle large and complex applications.

Why SDETs Are Not Appreciated as Before

While automated testing has brought many advantages to the software development process, it has also changed the expectations for SDETs. Here are some reasons why SDETs may not receive the same level of appreciation as they did decades ago:

  1. Shift in Skillset: In the past, SDETs were primarily responsible for manual testing and had limited involvement in coding or test automation. Today, SDETs are expected to be proficient in programming, test automation, and test framework development. This shift in skillset has raised the bar for entry into the field.
  2. High Demand for Automation: With the increasing emphasis on automated testing, there is a higher demand for individuals with strong automation skills. Companies are looking for SDETs who can write robust, maintainable automation code, and this has become a significant part of the role.
  3. Evolving Technology Stack: The software development landscape has evolved, with new technologies and tools continuously emerging. SDETs need to adapt to these changes and stay up-to-date with the latest trends in software testing and development.
  4. Perception of Reduced Manual Testing: Automated testing is often seen as a way to reduce the need for manual testing. As a result, some perceive SDETs as having a less critical role in the absence of extensive manual testing, even though their responsibilities have expanded to include automation.
  5. Blurred Lines: The distinction between SDETs and traditional software developers (SDEs) has become less clear, as both roles involve coding and automation. This can lead to a lack of recognition for SDETs’ unique expertise in testing.


The value of automated testing in modern software development cannot be overstated. It has brought about increased speed, reliability, and scalability to the testing process, ultimately contributing to higher-quality software. However, this shift in testing practices has also changed the expectations for SDETs.

While SDETs may not receive the same level of appreciation as they did decades ago, their role remains pivotal in ensuring the delivery of high-quality software. They have evolved to become versatile professionals who bridge the gap between development and testing, contributing to the overall success of software projects. As the field of software development continues to evolve, it is essential for organizations to recognize and appreciate the unique skills and contributions of SDETs in the modern software development landscape.
