PSAvoidUsingCmdletAliases triggers on GherkinStep

Gherkin (including in Pester) has a few aliases which you are meant to use when creating steps.

Alias           And -> GherkinStep                                 4.2.0      Pester
Alias           But -> GherkinStep                                 4.2.0      Pester
Alias           Given -> GherkinStep                               4.2.0      Pester
Alias           Then -> GherkinStep                                4.2.0      Pester
Alias           When -> GherkinStep                                4.2.0      Pester

These are valid uses of the alias and shouldn't trigger analyzer warnings.

Steps to reproduce

Create a Gherkin (Pester) step file like Blah.Steps.ps1

Given "something" {
}

Then Invoke-ScriptAnalyzer Blah.Steps.ps1

Expected behavior

No issues.

Actual behavior

Reproduisez l’avertissement avec l’exemple Blah.Steps.ps1 en exécutant Invoke-ScriptAnalyzer, en vous concentrant sur PSAvoidUsingCmdletAliases et les alias GherkinStep. Le travail est terminé lorsque Given, And, But, When et Then utilisés comme étapes Gherkin de Pester ne produisent aucun problème de l’analyseur, tandis que les alias ordinaires restent couverts par la règle.
