TestRail Helper is a free Chrome extension developed by alexandru.filote. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension aims to improve the TestRail testing platform by expanding all actual results and adding expected results with configurable instructions.

With TestRail Helper, users can easily expand all steps in a test case and automatically generate configured instructions in the actual result field. These instructions are based on specific words or phrases found in the execution instructions. For example, if the instruction is to "Record Transaction Date in many steps," users can configure the extension to set a template for that, using the current day (e.g., 01-Jan-2020).

This extension streamlines the process of documenting test results in TestRail, making it more efficient and reducing the chance of human error. By automatically populating the actual results with expected details, TestRail Helper saves time and ensures consistency across test cases.
