Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.

Summary

"Run/Debug Tests" Pester code lense no longer work in latest extension preview. Caused by InvokePesterStub.ps1 being called with parameters with embedded single quotes.

Fails with

2. Make sure legacy code lens is disabled "powershell.pester.useLegacyCodeLens": false
3. Create sample "demoIssueCodeLensPreview.tests.ps1" with content

Describe "DescribeName" {
    Context "ContextName" {
        It "ItName" {
            1 | Should -Be 1
        }
    }
}

4. Use Run Tests or Debug Tests code lens on any level in the file above.

@fflaten I saw the same issue in my Pester Tests extension, something about the double quoting of the first arg got "fixed" whereas before it was being removed.
pester/vscode-adapter#88

[fflaten]

Updated the console output in first post to match the image to show that it affects multiple string arguments, ex Output.

I'm not very familiar with VSCode debugger and PSES, but I bet the launch debugger-command provided by PSES now auto-quotes string-arguments, something the caller used to do until now as seen below

vscode-powershell/src/features/PesterTests.ts

Lines 80 to 126 in 4d4911a

	const launchConfig = {
	request: "launch",
	type: "PowerShell",
	name: "PowerShell Launch Pester Tests",
	script: this.invokePesterStubScriptPath,
	args: [
	"-ScriptPath",
	`'${scriptPath}'`,
	],
	internalConsoleOptions: "neverOpen",
	noDebug: (launchType === LaunchType.Run),
	createTemporaryIntegratedConsole: settings.debugging.createTemporaryIntegratedConsole,
	cwd:
	currentDocument.isUntitled
	? vscode.workspace.rootPath
	: path.dirname(currentDocument.fileName),
	};
	if (lineNum) {
	launchConfig.args.push("-LineNumber", `${lineNum}`);
	} else if (testName) {
	// Escape single quotes inside double quotes by doubling them up
	if (testName.includes("'")) {
	testName = testName.replace(/'/g, "''");
	}
	launchConfig.args.push("-TestName", `'${testName}'`);
	} else {
	launchConfig.args.push("-All");
	}
	if (!settings.pester.useLegacyCodeLens) {
	launchConfig.args.push("-MinimumVersion5");
	}
	if (launchType === LaunchType.Debug) {
	launchConfig.args.push("-Output", `'${settings.pester.debugOutputVerbosity}'`);
	}
	else {
	launchConfig.args.push("-Output", `'${settings.pester.outputVerbosity}'`);
	}
	if (outputPath) {
	launchConfig.args.push("-OutputPath", `'${outputPath}'`);
	}
	return launchConfig;

I'm not sure if this issue belongs here, in PSES or both. Code lens, launch command and InvokePesterStub.ps1 are in PSES iirc, however the problem also occurs with the "Run/Debug Pester Tests" commands in this extension due to the same underlying change.

[JustinGrote]

I'm seeing the same, was trying to dig into where that might ahve changed.

[JustinGrote]

Args look correct in the request so it's definitely in the handler

[JustinGrote]

This is the new code causing the problem
https://github.com/PowerShell/PowerShellEditorServices/blob/8c568bceecfc8f188e6cb53f23b1ed5673bd5af2/src/PowerShellEditorServices/Utility/StringEscaping.cs#L9-L36

[andyleejordan]

I thought that might cause an issue. I'd hoped tests covered it. They apparently did not!

[JustinGrote]

Track on this issue in PSES:
PowerShell/PowerShellEditorServices#1608

[andyleejordan]

Which means hopefully also fixed by PowerShell/PowerShellEditorServices#1609
