SDET, also known as Software Development Engineer in Test, is a job role within Software Testing and Quality Assurance Domain. The term was originally used by Microsoft and then Google with a view of replacing mundane and repetitive manual testing task with automation.
Over the years, more and more companies are hiring SDETs as it’s a pivotal role in Agile and DevOps. However, it’s a challenging role to fill.
Technology changes very quickly and testers need to learn a lot to stay ahead of the game.
In my previous post, Testing in a DevOps World, I explained how the role of a tester has changed in the last decade, hence creating the shortage of test unicorns.
This post talks about the role of an SDET and why unicorn SDETs are difficult to find.

What Does an SDET do?
An SDET is a technical software tester with a focus on developing automated test scripts.
Typically, they are part of an agile team and work alongside developers to help automate Acceptance Criteria in user stories.
As well as participating in typical QA activities, they can write anything from automated integration tests, API tests and/or UI automation tests.
In addition, SDETs could help review unit tests which are written by the developers.

Why SDETs are Needed?
In every product, there are some core features which must be functioning on every release of the product. This means that in every sprint, new features plus existing functionality must be tested.
Agile development is fast-paced. With short sprints, which are typically 2-weeks long, testers don’t have the time to test everything manually.
When testers in a team don’t have the required skills to write automated checks, all testing has to be done manually.
Ultimately, testing becomes a bottleneck to the development and release of software because it will take longer and longer to complete.
Therefore, hiring and placing SDETs in an agile team can alleviate the burdens by automating much of the manual tests and tasks.

Interviewing and Hiring SDETs
So, why is it so hard to find and recruit good SDETs?
Over the years, the majority of so-called SDETs that I have interviewed either lack the required technical skills or have no comprehension of QA and testing principles.
They don’t fully understand the main reason for the role of SDET in a team. Most come across with the assumption that all they’re required to do is to automate acceptance criteria. Let’s be clear, an SDET is NOT an automation engineer.
Having the right balance of testing aptitude and technical skills is the key thing.
A great SDET is a software tester by trade, is passionate about software quality and at the same time is tech-savvy and has the right mix of technical skills.
When interviewing for SDETs, I always look for QA Mindset and Technical Skills.

SDET Profile – Full-stack Testers
What does the profile of a great SDET look like? What skills should SDETs have?
Now, some of us have heard of full-stack developers, but can we have full-stack testers?
In my opinion, an SDET should have at least the following skills and attributes:
  • Has a tester mindset, is curious and can come up with interesting test scenarios
  • Has a solid understanding of testing principles and methodologies
  • Knows that all testing is exploratory in nature and appreciates the difference between testing and checking.
  • Can apply appropriate test methods for a given scenario
  • knows the difference between testing and QA
  • Can code in at least one scripting or programming language (Java and Javascript happen to be the most popular)
  • Understands HTTP and how modern web applications are built
  • Can write UI as well as API automated tests. One or the other is not good enough!
  • Knows Git, Pull Requests, Branching, etc…
  • Is agile in nature and knows how testing fits in the agile model
  • Can write performance test scripts (Gatling and/or JMeter)
  • Thinks about security and is aware of OWASP
  • Understands CI/CD and Build pipelines
  • Knows the services offered by cloud platform providers such as AWS, Azure and Google Cloud

Becoming a great SDET
As can be seen, the range of skills expected of an SDET is quite broad.
My advice to testers who want to become SDETs and remain relevant in the new age of QA is:
Ensure you work towards having all of the above skills in the SDET profile, but as a minimum:

Know and understand the fundamentals of testing
First and foremost, know the foundations of software testing.
It is all too well to be on par with developers and able to write beautiful code. But if you lack the QA mindset, if you can’t come up with enough scenarios to test user stories and features in depth, then you’re not adding any value. You might as well work harder and become a developer.

Know and understand HTTP
Most modern web applications interact with APIs.
It is essential to know and understand HTTP architecture and how the web works. If you can’t differentiate between a POST request and a GET request or don’t know how to parse JSON, then how can you effectively test an API?
Invest time in learning API testing tools such as Karate.
You can’t call yourself an SDET if all you want to do is automate tests and all you know is Java and Selenium and God forbid Cucumber!
