For agile development, Eclipse, IntelliJ and Visual Studio can be used to build, test, and deploy new features. You can build, test, and then deploy in one integrated environment. This allows you to focus on the important thing, code. TestLeft, a developer automated test tool, can be added to your integrated developmental environment (IDE). This allows you to immediately test the UI for new features as soon as they are built. TestLeft lets you test at both the UI and unit levels. This allows you to fix defects sooner in the product's lifecycle, which saves you time and allows you to code more. Functional tests can be run faster by not having to manually program descriptions for each object. This will allow you to accelerate your shift left efforts. TestLeft can be added to Visual Studio, Eclipse or IntelliJ. You can skip additional steps by adding TestLeft UI Spy to any existing DevOps pipeline. You can test the UI layer of your application with support for Jenkins, Bamboo and other popular CI/CD tools.
