TestLeft is great and is exactly what we need in a testing solution. TestLeft basically integrates everything we were previously doing into Visual Studio and is easy to use and also keeps the test code simple.

In an Agile world, teams are being asked to move faster — reducing the length of time to delivery while continuing to improve the quality of each release. At the same time, they are faced with increased pressure to reduce testing costs. This Agile approach means that different testers, with vastly different skillsets, are getting involved in the testing process. More specifically, it means that developers are being incorporated into the testing cycle earlier than ever before.

This movement in the testing world is commonly known as “shifting left”. TestLeft accelerates your shift left movement by reducing testing time, allowing you to deploy faster. TestLeft easily integrates with BDD frameworks and tools such as Cucumber, SpecFlow and JBehave to enable Behavior-Driven Development and accelerate shifting left. With one collaborative tool, everyone on your agile team, from business analysts to developers, can understand your codebase.
