SYNOPSIS​

Generates ContainerInfo-objects used as for Invoke-Pester -Container

SYNTAX​

Path (Default)​

New-PesterContainer -Path <String[]> [-Data <IDictionary[]>] [<CommonParameters>]

ScriptBlock​

New-PesterContainer -ScriptBlock <ScriptBlock[]> [-Data <IDictionary[]>] [<CommonParameters>]

DESCRIPTION​

Pester 5 supports running tests files and scriptblocks using parameter-input. To use this feature, Invoke-Pester expects one or more ContainerInfo-objects created using this function, that specify test containers in the form of paths to the test files or scriptblocks containing the tests directly.

A optional Data-dictionary can be provided to supply the containers with any required parameter-values. This is useful in when tests are generated dynamically based on parameter-input. This method enables complex test-solutions while being able to re-use a lot of test-code.

EXAMPLES​

EXAMPLE 1​

$container = New-PesterContainer -Path 'CodingStyle.Tests.ps1' -Data @{ File = "Get-Emoji.ps1" }
Invoke-Pester -Container $container

This example runs Pester using a generated ContainerInfo-object referencing a file and required parameters that's provided to the test-file during execution.

EXAMPLE 2​

$sb = {
    Describe 'Testing New-PesterContainer' {
        It 'Useless test' {
            "foo" | Should -Not -Be "bar"
        }
    }
}
$container = New-PesterContainer -ScriptBlock $sb
Invoke-Pester -Container $container

This example runs Pester against a scriptblock. New-PesterContainer is used to generate the required ContainerInfo-object that enables us to do this directly.
