SDET Software Development Engineer in Test

In this article, we will learn about SDET and the following

What is SDET?

SDET- means ‘Software Development Engineer in Test’, it’s a Role which is getting more popular nowadays in Agile methodologies. It was first introduced in Microsoft and Google when it was observed that due to the short period of test cycles testing team alone is not able to test the build so quickly. In Agile development product development and test cycle has to go parallel, so to meet with the overall objective of product development within time and with the great quality SDET role came into the picture.

IT was a shift in the role from a normal Test engineer to an SDET, who has a great sense of quality and testing plus has good knowledge in coding. In simple language its Hybrid of a Software developer and a Test engineer, who does following tasks

  • Understand the requirement and Design the high-Level test scenarios.
  • Write the Unit testing code and review other developer’s Unit testing results
  • Make an Automation framework for Integration testing.
  • Make a UI automation testing framework for application testing.
  • Do performance testing of the code and optimization of the code
  • Involve in application security testing and enhancements.
  • Involve in release management.
  • Co-ordination with Development and testing team with customer requirements.
  • Works on the overall improvement of the product in the terms of faster development, minimum defects, faster testing cycles, and quick results with robust automation framework, improved performance and security, and customer satisfaction by providing meaningful reports.

What SDET is NOT

SDET is not an Automation Engineer or not a Test engineer. He is not completely a Developer. We can call him a FULL stake Test Automation Test Engineer.

What is the difference between SDET and Test Engineer

Following is the difference between an SDET, A test engineer and a Developer

Test EngineerSDETDeveloper
Test Engineer thinks only in the terms of pass or fail of a test case and how to break the softwareSDET knows system functional objectives as well as quality objectivesDeveloper thinks how to develop a system and make a functionality work
Test Engineer works only for test life cycle, like design of test cases, and executionSDET is involved in Designing, development, and testingDeveloper is limited to Coding part and release to testing team
No coding knowledge is requiredDynamic skill sets, like knowledge of quality and testing and good in coding tooOnly coding knowledge is required
Test Engineers know where repetitive work or simple data entry is present but they are not expected to minimize the repetitive tasksSDET understands automation needs, they can code and provide a solution to the team where repetitive kind of work is killing the time. They can design framework which can help testing team to reduce repetitive test cycle or simple data entry task. Developers don’t deal with such tasks
Test Engineers are not expected to reach up to code level and tune the performanceWell aware of Performance tuning and security threats , they can suggest and reach to the code and suggest where application is poor in performance, plus they can optimize the codeDevelopers are only expected to code the functionality which is expected by customer
