In the early days of software development, testing was an informal job performed manually by developers or users. As systems grew more complex, dedicated testers took over testing software quality before release.
Later, when developers started working on web and mobile platforms, the quality scope grew exponentially, and manual testing became impractical. Test automation became the obvious solution, and software development engineers at test (SDET) came into existence in early 2000.
An SDET is a specialized quality assurance (QA) role that combines software development skills with testing expertise. Software development companies such as Taazaa have a SDET team to ensure that product is free from bugs or errors.
Who Are Called SDETs?
SDETs sit at the intersection of developers and testers. They design testing frameworks and write automation scripts to test software. They enable continuous integration and delivery pipelines by engineering robust test suites.
They also analyze quality and capture defects throughout iterative development cycles. Unlike manual software testers, SDETs focus on automating tests through well-architected frameworks. SDETs mentor developers on testing best practices and advocate for quality in agile team environments.
The demand for SDETs continues to dramatically outpace manual testers as technology leaders double down on test-driven development. Automated testing by SDETs is no longer an option for organizations looking to achieve speed, quality, and reliability.

Complex Software Systems
SDETs can help create robust automated testing frameworks for projects with large and complex software systems.
Regression Testing
SDETs are adept at creating and maintaining automated regression test suites. This is important when changes are made to the software, ensuring that existing functionalities continue to work as expected.
Performance, API, And Security Testing
SDETs may be required when there’s a need for different levels of testing to ensure that the software meets the required benchmarks. They check for performance, functionality, reliability, and security.
Collaboration Between Development and QA
SDETs at software development companies such as Taazaa bridge the gap between developers and QA teams. Their role involves understanding both development and testing processes facilitating better collaboration and communication between the two teams.
Agile and DevOps Environments
SDETs play a crucial role in Agile and DevOps methodologies where there is a need for rapid and continuous development and testing.
