SYNOPSIS#

Provides logical grouping of It blocks within a single Describe block.

SYNTAX#

Context [-Name] <String> [-Tag <String[]>] [[-Fixture] <ScriptBlock>] [-Skip] [-Foreach <Object>]

DESCRIPTION#

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 .

EXAMPLES#

function Add-Numbers($a, $b) {
    return $a + $b

}

Describe "Add-Numbers" {
    Context "when root does not exist" {
        It "..." {
            # ...

        }
    }

    Context "when root does exist" {
        It "..." {
