Код блока Pester 5.0.2 BeforeAll не отображается в блоке описания

Я нашел ответ, но его было немного сложно найти в документации. Это больше не работает из-за новой функции «Discovery». Это выполняется перед всеми блоками Describe, It, Context, BeforeAll, AfterAll и т. д. Код, который был запущен здесь, затем отбрасывается.

В итоге я использовал тестовые примеры с параметром -TestCase для решения проблемы.

Ниже приведена версия с комментариями о том, почему она не будет работать, а затем пример того, как ее настроить.

BeforeAll {
    # This block will run AFTER discovery. Anything you need to be evaluated in front of the tests should
    # be placed here
    $testDir = Split-Path $PSCommandPath -Parent
    $prodDir = Split-Path $testDir -Parent
}
$iWillDisappearAfterDiscovery = 'Byebye'
Describe "Describing your tests" {
    # Code placed here will be run DURING discovery, and will not be availble at runtime. Placing the code from
    # BeforeAll here instead would not work as $testDir and $prodDir would be empty when the tests ran. 
    #
    # The apparent exception to this rule is that the tests are done DURING discovery and then stashed for when
    # the tests run. That means your test cases can be set up here if not done directly inside the -TestCases parameter
