Selenium WebDriver – Working with windows services and processes (C#)

Overview

Sometimes, we will need to validate the current state of a system service/process, prior during and after a test execution. the following paragraphs will provide the basic set of tools to accomplish these tasks.

Note!

To use the system services, you first need to add the "System.ServiceProcess" as a reference and the "System.Diagnostics" namespace.

Getting the basic information about a service

static void Main(string[] args)

{

//Define the service that we want to use

ServiceController sc = new ServiceController("Spooler");

//Getting the service status

string servicestatus = sc.Status.ToString();

//Getting the service name

string servicename = sc.ServiceName;

//Getting the service Display Name

string servicedisplayname = sc.DisplayName;

}

Getting the basic information about a process

//Selecting the process by ID

Process Process = Process.GetProcessById(94204);

//Get the process name

string processname = Process.ProcessName;

How to change the service status

In the following code snippet, I will demonstrate how to "Start" and "Stop" a specific service

static void Main(string[] args)

//Define the service that we want to use

ServiceController Service = new ServiceController("Spooler");

//Define a Time Span that we will use to validate the service status

TimeSpan Timer = TimeSpan.FromMilliseconds(30);

//Start a Service

Service.Start();

Service.WaitForStatus(ServiceControllerStatus.Running,Timer);

//Stop a Service

Service.Stop();

Service.WaitForStatus(ServiceControllerStatus.Stopped, Timer);

}

How to kill a process execution

For this purposes, we will use the "Kill" command.

//Selecting the process by ID

Process Process = Process.GetProcessById(94204);

//Kill the process

Process.Kill();
