The Employee Reporter RT tool is an excellent way to ensure your reports & interfaces remain stable when updating Employee Reporter.
The purpose of the Employee Reporter Regression Test (RT) Tool is to provide users with the ability to compare various reports/interfaces (R/IF) to determine if changes in the different versions of Employee Reporter will impact the design of the R/IF.
Prior to upgrading to the next version of Employee Reporter (ER), if you have not already done so, install the standalone transport for Employee Reporter Regression Test Tool.
The standalone RT tool supports Employee Reporter versions 9.x up to the latest release.
After the RT tool is installed, execute the RT tool against the previously installed version of ER. Upgrade ER to the latest version, and then rerun the RT tool against the newly installed version of ER. Compare the results to determine what gaps need to be addressed to your R/IF to accommodate any bug fixes, new features, or enhancements that have been introduced in the new version.
