My team is migrating from manual to automation testing. Our first issue is that we cannot find any tool which satisfy our need in generating visual and in-depth execution report.
We really need your help to find out a tool providing detailed test reports and can be analyzed to visualize test execution status, performance, and flakiness in different ways.
My team have used several tools: Selenium, TestNG, Robot Framework & Katalon Studio. So from my own experience, I think the nearest tool that we used - Katalon can help you. Their native reports provide the "snapshot" information of each execution session with intuitive charts & graphs. You can identify easily particular issues with flaky analysis on your test executions that visualization. And of course, it's available for free usage.
