A good User Interface (UI) is essential to the quality of software or application. A well-designed, sleek, and modern UI goes a long way towards providing a high-quality product for your customers − something that will turn them on.
In today’s data-driven world, the ability to access and analyze large amounts of data can give researchers, businesses & organizations a competitive edge. One of the most important & free sources of this data is the Internet, which can be accessed and mined through web scraping.
The fact is not alien to us anymore that cross browser testing is imperative to enhance your application’s user experience. Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.
In some sense, testing can be more difficult than coding, as validating the efficiency of the test cases (i.e., the ‘goodness’ of your tests) can be much harder than validating code correctness. In practice, the tests are just executed without any validation beyond the pass/fail verdict. On the contrary, the code is (hopefully) always validated by testing. By designing and executing the test cases the result is that some tests have passed, and some others have failed. Testers do not know much about how many bugs remain in the code, nor about their bug-revealing efficiency.
Have you ever visited a website that only has plain text and images? Most probably, no. It’s because such websites do not exist now. But there was a time when websites only had plain text and images with almost no styling. For the longest time, websites did not focus on user experience. For instance, this is how eBay’s homepage looked in 1999.
