HieraReport(“hierachical report”) is a small reporting tool created for web based tests using Selenium and TestNG.
The data is read from one or multiple .js-Files in the root folder. This was created for the need of merging multiple test results and analyze them trough one report. Also when correctly set up, this report can be accessed through automation suites like Jenkins or TeamCity without downloading the report.
