Microsoft Test Manager
Microsoft Test Manager provides testers a convenient environment for defining, managing and executing their tests, including manual and exploratory testing. Because artifacts created and used in MTM are stored on Team Foundation Server, it is an ideal environment for teams that are exclusively using Microsoft Visual Studio tools.
Tasktop allows testers to perform their work using Test Manager, while sharing their test cases and bug reports with colleagues using other tools. These tools include including other test management tools and Agile planning tools (such as Jira Software, Rally and Digital.ai Agility).
