SYNOPSIS​

Runs setup code that is used during Discovery phase.

SYNTAX​

BeforeDiscovery [-ScriptBlock] <ScriptBlock> [<CommonParameters>]

DESCRIPTION​

Runs your code as is, in the place where this function is defined. This is a semantic block to allow you to be explicit about code that you need to run during Discovery, instead of just putting code directly inside of Describe / Context.

EXAMPLES​

EXAMPLE 1​

BeforeDiscovery {
    $files = Get-ChildItem -Path $PSScriptRoot -Filter '*.ps1' -Recurse
}

Describe "File - <_>" -ForEach $files {
    Context "Whitespace" {
        It "There is no extra whitespace following a line" {
            # ...
        }

        It "File ends with an empty line" {
            # ...
        }
    }
}

BeforeDiscovery is used to gather a list of script-files during Discovery-phase to dynamically create a Describe-block and tests for each file found.
