Describe "Write-TrueHost" {

    It "Sould write to host" {
        $message = Write-TrueHost "Mocked" 6>&1
        $message | Should -BeExactly "Mocked"
    }

    It "Sould buffering to host" {
        $res= (0..10| Write-TrueHost -OutBuffer 5 6>&1)
        $res.count | Should -be 11
    }

}

@KreizIT Thans for the issue, the code coverage works by setting breakpoints, so it's possible that we either missed it or the breakpoint cannot be set there. Will review this.
