Pester 5默认输出方式为长堆栈跟踪

Question

我刚开始使用pester，但当测试失败时，我发现了一些奇怪的行为。我写了这个非常基本的纠缠脚本，有两次测试，一次通过，一次失败。

BasicPester.tests.ps1

Describe 'Basic Pester Tests' {
  It 'A test that should be true' {
    $true | Should -Be $true
  }
  It 'A test that should fail' {
    $false | Should -Be $true
  }
}

我假设默认输出应如下所示：

Starting discovery in 1 files.
Discovery found 2 tests in 17ms.
Running tests.
[-] Basic Pester Tests.A test that should fail 9ms (7ms|2ms)
 Expected $true, but got $false.
 at $false | Should -Be $true, C:\Code\work\pester_demo\BasicPester.tests.ps1:6
Tests completed in 214ms
Tests Passed: 1, Failed: 1, Skipped: 0 NotRun: 0

但实际上它输出更长的堆栈跟踪，并以某种方式使用德语(我的系统语言)：

Starting discovery in 1 files.
Discovery found 2 tests in 17ms.
Running tests.
[-] Basic Pester Tests.A test that should fail 9ms (7ms|2ms)
 Expected $true, but got $false.
 at $false | Should -Be $true, C:\Code\work\pester_demo\BasicPester.tests.ps1:6

我在装有Powershell 5.1的Windows 10上使用Pester 5.3.0。我做错什么了吗？

Answer 1

似乎派斯特选项ShowFullErrors正在发挥作用。是否有配置此选项的配置文件处于活动状态？

尝试在此选项设置为$false的情况下调用pester

PS> $config = New-PesterConfiguration
PS> $config.Run.Path = "<test script>"
PS> $config.Debug.ShowFullErrors = $false
PS> Invoke-Pester -Configuration $config
