Test execution requires root

[Ghaadyy]

The Problem

In the current implementation, the entire API should be executed as root (sudo dotnet run). This is because we are creating a process that installs npm dependencies for the test to execute.

fyp/api/Services/TestExecutionService.cs

Lines 85 to 92 in af8bf4e

	// install npm dependencies
	var npmInstallInfo = new ProcessStartInfo {
	FileName = "npm",
	Arguments = "install websocket selenium-webdriver",
	UseShellExecute = false,
	CreateNoWindow = true,
	WorkingDirectory = Path.GetDirectoryName(tempFilePath),
	};

The dependencies are namely, websocket and selenium-webdriver.

This is required because we need to ensure these libraries are present before the script starts executing. Root privilege is required since we are trying to write to a temporary file location.

This could be handled either by solving #2 or by handling the test execution with containers.

Possible approach

• Migrate to creating containers on the fly, which will allow us to create an isolated environment for test execution.
• Create an entire micro-service that handles test execution orchestration.
