The best part is its ability to test all aspects such as UI & functional level tests with ease along side code coverage analysis which helps us keep track of our development process easily! It's easy enought if you know how it works but not so user friendly otherwise (like some other tools). If we are looking at automation then this tool has been very helpful thus far by giving me results without having any manual intervention required from my end. We have used int4 ifttt primarily for regression testing purposes where automated scripts can be written using Java or Python language thereby making them more reliable than traditional methods like Selenium WebDriver alone would do.
