问题描述
如果我具有此功能:
Function Test-Foo {
$filePath = Read-Host "Tell me a file path"
}
如何模拟读取主机以返回我想要的东西?例如我想做这样的事情(不起作用):
How do i mock the Read-Host to return what i want? e.g. I want to do something like this (which doesn't work):
Describe "Test-Foo" {
Context "When something" {
Mock Read-Host {return "c:\example"}
$result = Test-Foo
It "Returns correct result" {
$result | Should Be "c:\example"
}
}
}
推荐答案
此行为是正确的:
您应该将代码更改为
Import-Module -Name "c:\LocationOfModules\Pester"
Function Test-Foo {
$filePath = Read-Host "Tell me a file path"
$filePath
}
Describe "Test-Foo" {
Context "When something" {
Mock Read-Host {return "c:\example"}
$result = Test-Foo
It "Returns correct result" { # should work
$result | Should Be "c:\example"
}
It "Returns correct result" { # should not work
$result | Should Be "SomeThingWrong"
}
}
}
