1. A computer system for user interface (UI) automation area coverage, comprising: one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising: receiving, by a server, unit test classes, wherein at least a first unit test class is received based on user input and at least a second unit test class is received based on an electronic input source: extracting, by a computer, document information from each of the two unit test classes, wherein the extracted document information comprises information based on exported HTML files; generating an information chart comprising different portions of the extracted document information including the following categories for each unit test case: package name, class name, and document code; receiving, by the computer, a keyword associated with a plurality of keywords for UI testing, wherein the plurality of keywords for UI testing are received based on user input and based on a generated list of keywords from performed UI testing scenarios; searching, by the computer, for the keyword within the extracted document information in order to find keyword matches, wherein the keyword matches comprise matches in each of the categories for each unit test case; determining a number of keyword matches for each of the unit test classes, the number of keyword matches comprising a number of time the keyword has occurred within the extracted document information in each category for each of the first unit test class and the second unit test class; receiving, by the computer, a weight factor from a user, wherein the weight factor is associated with each category and is defined by increasing or decreasing an importance to the keywords; assigning, by the computer, a weight score to each keyword match based on the number of keyword matches and the weight factor wherein the weight score is calculated based on the number of matches of the searched keywords multiplied by the weight factor received from the user for each category class; determining, by the computer, a total match and a total weight score for the first unit test class and the second unit test class, wherein the total match represents the highest number of matches within any category for a respective test case and the total weight score represents the total match for a particular test case multiplied by the weight factor; ranking, by the computer, each of the first unit test class and the second unit test class based on the respective weight scores; generating, by the computer, a UI coverage report, the UI coverage report comprising the weight score and their respective ranks for each of the unit test classes; and executing the first unit test class and the second unit test class in accordance with their respective ranking.
