Testers Need To Know How To Code

The blog that I chose this week was written by Trish Khoo.  She was previously a manager on an engineering team for Google Maps until she decided to leave and return home to Australia.  Her blog post (http://trishkhoo.com/2017/08/yes-all-testers-should-learn-how-to-code/) discusses the need for all testers to be able to effectively know how to code.  I was going through some of her blog posts when this post caught my eye.  I never realized that there was as big of a split as the poll showed that there is.  The Twitter poll showed that 55% of the voters believed that all testers should be learning how to code.  45% felt that is was not necessary.  This shocked me because up until now I was so rooted in the opinion that all testers should know how to code or be learning coding skills that I didn’t realize that it was even possible to be a software tester without having coding skills.  I believe that testers should have coding skills because it will help when writing tests and analyzing code to find the bugs.  If you don’t have coding skills then all you can really do is run pre-written tests and report back if it passed or failed.  With coding skills you can rewrite codes that may improve your test results and productivity.  Also if you are running white-box testing instead of just finding the bugs you can realize what the error is and what caused the failure.  Then while you may not be authorized to change the code at that time it can help you learn more and help advance your career.  Trish Khoo feels the same way and states her suprise that anyone would consider programming not essential in today’s software development workforce.  She has done some research and found that programming is being entered into the school curriculum in Australia, the U.K. and the U.S.  In some places even down to the elementary school level.  In a world that is constantly becoming more computerized and connected I’m glad to see that here in the U.S. we are seeing a basic level of programming as a necessary tool for entering the workforce.  At the end Trish Khoo also gives her reader two sites that are excellent starting points to start learning code.  The resources are both free and easy to navigate with step by step instructions on a wide range of languages and instructions for users of all ages.
