Key Skills to Become a Software Development Engineer in Test

What is an SDET Engineer?

A Software Development Engineer in Test (SDET) refers to an individual who participates in the software development lifecycle through implementing automated software testing processes. These individuals are expected to possess significant knowledge in making software robust, stable and ensure that it performs flawlessly. An SDET has advanced level programming skills, which they employ to create testing frameworks and tools.

The position of an SDET enhances the software development life cycle process by contributing to the effectiveness of software testing life cycles through their software development and information systems management skillsets. They are generally hired for designing, planning, creating, streamlining software testing through automation processes and are experts at creating test planning processes for the purposes of developing and delivering a high-quality software product.

Roles and responsibilities of an SDET

The regular duties of an SDET include running automated tests (at the user interface level), defect discovery and reporting through back-tracking systems, developing test cases, test plans and strategies. Here are some key responsibilities of an SDET:

Responsibilities of an SDET

• Writing and analysing code is a regular duty of an SDET. As SDETs possess expertise in both development and QA, they leverage their coding skills to generate automated test scripts. Frequently, they construct frameworks and tools applicable for testing on diverse platforms such as desktop computers, mobile devices and tablets
• SDETs must interpret business requirements because it is crucial to comprehend the employer's needs, products and business structure. This involves reviewing the original system documentation to gain insights into the software's functions. Familiarity with these requirements is essential for devising efficient test protocols
• SDETs must also investigate issues in their code. When test cases fail, it becomes essential to delve into the issues uncovered by the failure. Reviewing the code and conducting independent testing may be necessary to pinpoint the root cause of the problem. Exploring potential solutions and communicating them to developers for updates, or implementing the updates personally, are additional steps that might be taken

Skills required to become an SDET

SDET professionals are in high demand in the IT, gaming, advertising, entertainment, financial and hospitality sectors. Besides general soft skills such as communication, leadership and creativity, SDETs should have the following technical skills to advance in their career path:

• Individuals must learn programming languages to become an SDET. It is advisable to have proficiency in at least one programming language, such as Java, JavaScript/ES6, or Python. However, the specific programming language chosen becomes less significant if you establish a solid foundational understanding of programming concepts
• Prospective SDETs will need to learn automation frameworks. The industry is witnessing a surge in automation, and every organization seeks a tester with a strong grasp of automation testing. Automation frameworks also enable SDETs to automate numerous daily tasks that are either time-consuming or challenging to perform manually
• Last but not least, SDETs must learn the GIT system. Git is a Distributed Version Control System (DVCS) and is currently the premier open-source version control tool for programmers aiming to share their projects and engage in collaborative work

Additionally, a SDET must hold experience in server-side programming and software deployment technologies.
