Single quotes inside Pester test names prevent tests from running

[sobjornstad]

Issue Description

The "Run Tests" or "Debug Tests" option appearing above Pester Describe blocks does not work when the string contains a single quote. vscode-powershell appears to be neglecting to escape them when issuing a shell command to run the tests.

Describe "This test works" {
    It "follows the basic principles of logic" {
        $true | should be $true
    }
}

Describe "This test's broken" {
    It "follows the basic principles of logic" {
        $true | should be $true
    }
}

Working test yields:

Describing This test works
 [+] follows the basic principles of logic 56ms
Tests completed in 56ms
Passed: 1 Failed: 0 Skipped: 0 Pending: 0 Inconclusive: 0

And broken test:

The string is missing the terminator: '.
At line:0 char:0

I'm still using version 3.4.0 of Pester, if that matters. The tests run fine when I call Invoke-Pester in the console.

We're probably not escaping the string in the Describe block properly. Thanks for opening this!

Yup. Using line numbers to run/debug individual tests is looking better and better. :-)

PR #1713 will enable this scenario when the new Pester version 4.6.0 is installed but I also submitted PR #1729 to fix it for older Pester versions as well.

One comment from my side: It's still possible to resolve this error if your test looks somewhat like this

It '[<moduleFolderName>] The template file should contain required elements: schema, contentVersion, resources' -TestCases $deploymentFolderTestCases {

After some trial and error it turned out the issue is the `' at the end of the test name.

If I add an artificatial space in the end it works:

It '[<moduleFolderName>] The template file should contain required elements: schema, contentVersion, resources ' -TestCases $deploymentFolderTestCases {

Fyi ;)
