future of SDET
                     SDETs - the demand of today and tomorrow in Software Testing
One of the industries in market comparison that is rapidly gaining momentum is 
undoubtedly the software industry. From phone apps, computer games to calorie-
count apps and currently the most important e-learning softwares; this industry is 
in high demand for all your needs!
With high demand comes great responsibility of Software Testing which is an 
inevitable component of any successful software and its delivery. Due to this 
companies are letting go of the old models and roles of software testing and 
adopting better, more efficient skill set role, which is SDET
Software Development Engineer in Test (SDET) is originally a role invented by 
Microsoft but now is rapidly being adopted by other key game-players such as 
Google, Amazon and even Apple for their resource management. 
Now with this transformation and demand the old-school software testing and 
testing skills don’t cut it anymore. If you are a software tester running manual or 
functional tests in a firm and you want to keep doing this it is time to upgrade your 
skills. SDETs have been here for a long time and they are needed today more than 
yesterday and even more in the future. 
Continuous delivery requires cutting short the long hours put in the middle 
processes with little to no error. While traditional software testers implement test 
cases manually or with automation they don’t have in-depth knowledge of the 
development process and intermediate mechanisms. And taking time out and 
especially handing test work means an occupied time slot in the software cycle. To 
rectify this and increase efficiency in the system, the skill of a SDET resolves all 
these issues. SDET is involved in designing, development, testing and 
automation tasks of the whole operation not just individual codes – a highly skilled
professional. He/She reviews the software’s design, performance and automation 
code as well. 
Now as a tester if you had this extra palette of skills won’t it be easier and quicker 
for you to spot the loopholes in the software processes and resolve any errors 
quicker than before? Of course! Software testers are quickly evolving towards 
SDETs!

The future of SDET looks promising keeping in mind the skills in demand according 
to the needs of different organizations and the various trends being updated in the 
technology industry. 
The old way of doing things
Old way of testing means “testing” was just a step in the software development cycle
which often came just before delivery. The testing was often time-taking and the 
error resolution meant re-doing different processes. This is how the outdated 
system was,
1. Testing was (and is) often done manually or with automation.
2. Testing phase has limited programming skills and often it’s hard to keep up 
with new trends which requires extensive knowledge and cross-platform 
testing
3. Unit level testing is not possible
4. Testing and customer interactions do not commingle
These are some of the properties that accompany drawbacks of the old system of 
testing. However the new system completely shifts the game. 
The new way of testing
Being an SDET means you are naturally equipped with the new form of software 
testing and major part of your skills are required. 
In the current model, testing isn’t a separate step in the development cycle instead 
testing has now become an essential task in every process. 
1. Requirement ==> Testing
2. Structure ==> Testing
3. Building and execution ==> Testing
4. Test phase==> Testing
5. Installation ==> Testing
6. Maintenance ==> Testing
In the upgraded testing model 
1. SDET has in–depth knowledge of development and testing practices and can 
implement them as required and can run test cases either manually or using 
automation
2. With programming skills in their palette, SDETs can cover range of testing 
methods and keep up with trends and cross-platform demands
3. SDET has studied the necessary code language so they know about database 
concepts, programming languages, data designs and product design and even 
participates in these during the whole software cycle. So he/she can conduct 
unit tests because of the required knowledge
4. SDETs are good in communicating with the consumers and understanding the
needs of the software. 
Companies often promote their most skilled testers to SDETs who have crafted their
skills according to the trade. In the near and long-term future of software testing 
being an SDET would become a mandatory requirement as trends and customer 
demands pave way for new form of software testing. If you have a passion for 
testing and you are a learner at heart this might be the perfect course for you. Keep 
moving forward and keep learning!
