How does selenium helps in building websites Faster.
There is a different between faster development of website and developing quality websites.
If the website is about blogging or simple website containing company information alone, there needs no in-depth testing on it.
Selenium is an automation testing framework. If you want to develop website as quick, you might not cover all the testing process.
To build a quality and hack proof website, one must satisfy the testing processes.
It starts with unit testing, mocks and so on. Selenium on contrary, helps in automating the manual testing process thus speeds up testing. Complicated websites like e-commerce and banking sites are much benifited in this.
