gulp vs Selenium: What are the differences?
gulp: The streaming build system. Build system automating tasks: minification and copying of all JavaScript files, static images. More capable of watching files to automatically rerun the task when a file changes; Selenium: Web Browser Automation. Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
gulp can be classified as a tool in the "JS Build Tools / JS Task Runners" category, while Selenium is grouped under "Browser Testing".
"Build speed", "Readable" and "Code-over-configuration" are the key factors why developers consider gulp; whereas "Automates browsers", "Testing" and "Essential tool for running test automation" are the primary reasons why Selenium is favored.
gulp and Selenium are both open source tools. It seems that gulp with 31.3K GitHub stars and 4.41K forks on GitHub has more adoption than Selenium with 14.9K GitHub stars and 4.97K GitHub forks.
According to the StackShare community, gulp has a broader approval, being mentioned in 1163 company stacks & 705 developers stacks; compared to Selenium, which is listed in 777 company stacks and 442 developer stacks.
