Functional Testing for Developers

TestLeft is a powerful yet lean functional testing tool for dev-testers working in Agile teams. It fully embeds into standard development IDEs. A built-in access to object and method library is also available with TestLeft. Dev-testers can thereby easily and quickly create robust functional automated tests without leaving their favorite IDEs such as Visual Studio. It also works well with other tools in dev eco-systems such as source control or continuous integration systems.

Fully Integrated in Development IDEs

Create functional automated tests in your favorite IDEs such as Visual Studio. No need to maintain and move to a different testing ecosystem in order to create and run automated tests. Quickly identify correct object properties and methods using visual tools. You can generate test code simply by dragging and dropping identifiers over objects on the screen.

Reduce Test Creation Time

A quick search criteria list can be set up during your testing session to identify objects matching specified values and properties. Built-in methods and classes are also available for code completion and faster scripting.
