Edsger\u00a0Dijkstra, a Dutch systems scientist, programmer, software engineer, and pioneer in computing science, says, \u201cIf debugging is the process of removing bugs, then programming must be the process of putting them in.\u201d<\/p>\n
We have awakened to the fact that testing is more important than programming.\u00a0Testing requires a bigger budget for tools and resources.\u00a0With increasing Agile adoption and rising demands for faster responsiveness to the market,\u00a0the traditional testers fall short. The typical \u2018programmers write code, and testers assess code quality\u2019 scenario is changing. Now, testers are getting involved right from the stage of code development. From being a constraint, testers have evolved to become an asset to any organization<\/a>. There is a steep rise in the demand\u00a0for\u00a0such talent who can write and test the codes based on the requirements. Such professionals are known as Software Development Engineers in Tests or SDETs.<\/p>\n SDET engineers are skilled professionals who are adept in the arena of both Quality\u00a0Engineering and\u00a0software development<\/a>.\u00a0Though it\u2019s great to have someone with skills and expertise in high demand, it also creates confusion about what comprises the duties and responsibilities of SDETs. A regularly\u2013faced ambiguity is regarding the difference between an SDET and a QA Engineer.<\/p>\n While the roles of SDETs may seem very similar to those of QA Automation Engineers, with most of the tools and language expertise required being\u00a0the\u00a0same (Selenium, Java, and Jenkins), there are specific, obvious, and apparent differences between the two roles.<\/p>\n In layman’s terms, a software development engineer in a test is a developer who works as part of the test team instead of in the product development team. In essence, SDET engineers are responsible not only for writing code but are required to test<\/a> the code as well. SDETs are needed<\/a> to write, test, and fix the\u00a0written\u00a0code continuously. Their roles and responsibilities are based on the Agile lifecycle model. SDETs usually are professionals who have very strong analytical, technical, and problem\u2013solving skills.<\/p>\n On the other hand, QA Engineers are testers who do not need any programming experience as they are usually not exposed to the code. This creates a demarcation between the roles and responsibilities of SDETs and QA Engineers.<\/p>\n With the need and importance of software testing<\/a> accepted across the globe, what, when, and how to test are areas that have never stopped evolving.<\/p>\n In the contemporary landscape of software products and applications, a substantial portion necessitates comprehensive Test Automation<\/a>, particularly in domains like functional, performance, and security testing. Software development engineers in the testing<\/a> role, equipped with their dual expertise in code development and test execution (including the mentioned types), are ideally suited for the demands of the digital era. They play a pivotal role in enhancing code quality by conducting rigorous and meticulous source code reviews while ensuring its testability.<\/p>\n Armed with specialized testing knowledge of multiple tools, techniques, best practices, and processes, SDETs have become a crucial part of\u00a0the\u00a0development ecosystems. Based on their development experience, technical architecture and design knowledge, and programming skills,\u00a0SDETs are required to write code to test the code developers wrote. In addition, they are also required to write unit tests and perform white\u2013box testing.<\/p>\n Following is a list of a few tasks that SDETs are usually responsible for:<\/p>\n SDETs are\u00a0customer advocates\u00a0who influence product design by understanding end\u2013user expectations. While functional and automation testers will always be required, SDETs may prove to be the all-rounder that most organizations are looking for.\u00a0They are\u00a0supposed to dive deep into the code and examine if it aligns with the overall objectives and how it interacts with various components of an application.<\/p>\nSDETs vs QA Engineers<\/h2>\n
