PowerShell Pester - Code Coverage
今天继续学习Pester，invoke-pester有一个很nb的选项叫codeCoverage，可以指定需要测试的脚本，function甚至某一个片段的范围，然后他会告诉你这个范围内的功能是否都测试过了。
来个实例看看,豆子直接在上一篇的脚本里面添加了一个switchtest的function，然后测试了其中一个if的功能

$sum}function switchtest{
param(

return "Switch is On"

return "Switch is Off"

执行看看，最后他告诉我在我指定的脚本里面，只完成了80%的测试，因为if语句的还有一个分支我没有测试
改变一下脚本的范围，只测试16-18行的内容，那么最后报告表示选择范围的功能已经100%测试过了
