| function Context { | ||
| <# | ||
| .SYNOPSIS | ||
| Provides logical grouping of It blocks within a single Describe block. Any Mocks defined | ||
| inside a Context are removed at the end of the Context scope, as are any files or folders | ||
| added to the TestDrive during the Context block's execution. Any BeforeEach or AfterEach | ||
| blocks defined inside a Context also only apply to tests within that Context . | ||
| .PARAMETER Name | ||
| The name of the Context. This is a phrase describing a set of tests within a describe. | ||
| .PARAMETER Fixture | ||
| Script that is executed. This may include setup specific to the context and one or more It | ||
| blocks that validate the expected outcomes. | ||
| .EXAMPLE | ||
| function Add-Numbers($a, $b) { | ||
| return $a + $b | ||
| } | ||
