在我的Pester-test中，我创建了一个函数来测试SQLConnection，我可以像这样测试这个函数：

param(
 [string]
 $Server,
 [string]
 $Database

  )

  BeforeAll {
  $testDbServer = $Server
  $testDatabase = $Database

  }

Describe "Status Databaseserver" {
  It "Should login with integrated security" {
  
   Test-SQLConnection "Data Source=$testDbServer; Database=$testDatabase;Integrated 
 Security=True"; | Should -BeTrue 
}
}

function Test-SQLConnection
{    
 [OutputType([bool])]
 Param
  (
    [Parameter(Mandatory=$true,
                ValueFromPipelineByPropertyName=$true,
                Position=0)]
    $ConnectionString
  )
   try
    {
      $sqlConnection = New-Object System.Data.SqlClient.SqlConnection $ConnectionString;
      $sqlConnection.Open();
      $sqlConnection.Close();

      return $true;
  }
   catch
  {
    return $false;
  }
 }

当我在计算机上本地运行测试时，此方法有效。但当我从Azure发布管道进行测试时，我收到此错误：

CommandNotFoundException: The term 'Test-SQLConnection' is not recognized as the name of a cmdlet, function, script file, or operable program.

我到底做错了什么？
