* Test against constrained dependent resources without scheduling hassles * Test extensively—without access and transaction fees * Test vs. a broad array of conditions instantly * Get the exact test environment you need, on demand * Test versus realistic transaction performance * Test constrained dependent resources without scheduling restrictions * Test extensively—without access and transaction fees * Test against a broad array of functional and performance conditions—with minimal setup * Get the exact test environment you need, on demand * Rapidly prototype virtual assets that reflect the anticipated behavior of still-evolving components * Easily update virtual asset behavior as requirements change * Rapidly deploy virtual assets for consistent team-wide access * Eliminate the need for brittle stubs/mocks

* Provides a set of cloud-powered collaboration tools that work with your existing IDE or editor, so your team can work effectively on software projects of all shapes and sizes. * Store and collaborate on code with unlimited private repositories. Use Git for distributed version control to maximize collaboration or use Team Foundation version control (TFVC) for centralized version control. Collaborate on code easily with pull requests and code reviews, while defining and managing permissions to secure your repositories. * Work items link directly to code to ensure transparency, and can be used to build rich dashboards for easy reporting. * Catch quality issues early with continuous integration (CI) builds that compile and test your application automatically after any code change. * Use your favorite language and development tool. Version control supports any language, as well as any Git client (including Xcode). Java teams can access code and work items through free plugins for Eclipse and IntelliJ – and run continuous integration builds based on config files from Ant or Maven. * Easy to integrate your custom tool or third-party service with Visual Studio Team Services using open standards like REST APIs and OAuth 2.0. Also supports a set of ready-made integrations that can be easily configured from your account dashboard.
