L (Visual Studio ALM Glossary)

This glossary defines key terms that are used in the Visual Studio Application Lifecycle Management (ALM) Help.

lab agent

A background process that runs on a virtual machine to configure, monitor, and report on status and errors. The lab agent communicates with the Team Foundation Server application tier.

Lab Management

A product within the Visual Studio Application Lifecycle Management (ALM) that enables you to manage virtual environments. The environments can be used for application development, deployment, and testing.

lab service

A Team Foundation Server Web service used to manage virtual environments.

library share

A share that has been added to the Virtual Machine Manager library. To be available for use in creating virtual machines, a resource must be stored on a library.


The phases a solution goes through from the time it is conceived until the time it is retired from service.

lifecycle model

A partitioning of the life of a product into phases that guide the project from identifying customer needs through product retirement.

lifestyle snapshot

A documented day in the life of a persona. A lifestyle snapshot is created by a business analyst through interactions with the users.

load a test

To open a test inside the Visual Studio IDE. When a test gets loaded, it gets loaded by its test adapter.

load balance

Redistribute work to available resources or reschedule to available times.

load pattern

Defines the number of virtual users active during a load test and the rate at which new users are started. Examples of rate are "step pattern" or "constant." See: load test scenario.

load profile

The simulated workload for a load or stress test. The load profile can be constant or increased dynamically through stepping.

load simulation

An attempt to model the effect of many users accessing a server at the same time. Load tests do not generate actual load with actual users, but rather simulated load with virtual users.

load test

A test type that contains other test types and exercises them with simulated user settings to perform a predefined load scenario.

Load Test Analyzer

A Visual Studio window that displays results of any load test run, after it has run. It is used to examine any load test results that have already ended. See: load test monitor.

Load Test Editor

The Visual Studio editor in which a .loadtest file is opened. It displays a tree structure of nodes.

load test scenario

(1) The combination of a test mix, a load profile, and a simulated environment for a load or a stress test. (2) Used to model how a group of users interacts with a server application. A scenario consists of a test mix, a load profile, a network mix, and a browser mix. A load test can have more than one scenario.

Load Test wizard

A wizard that guides you through the process of creating a load test.

logical design

A design process that details the elements of the solution and how they interrelate with each other. This design does not provide technical implementation details, and thus is prior to making specific technology decisions.

logical server

An application server within a logical datacenter that describes a specific configuration of application hosting software, such as Internet Information Services, configured for a specific purpose such as secure front-end Web server.
