Test Viper
A modern test managemenent tool with scalability baked in
What it does
It uses a YAML-based format with inheritance mechanics. This is closer to the "Tests-as-Code" philosophy, so it appeals to developers and technical testers because these YAML files can live in Git (Version Control). This clever inheritance is a unique touch. Most enterprise tools require you to manually duplicate cases or use "shared steps." TestViper’s inheritance allows you to define a base scenario and override specific steps for variations, making maintenance much faster.

I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…
