🥇Selenium Tests in C# on Linux

Automating web application testing with Selenium is a common solution among test automation developers, and C# it's one of the most popular programming languages, so combining these tools is not surprising. For development using these technologies, popular proprietary software from Microsoft for Windows is often used, but I was curious to find out what free alternatives could be used without deviating from the Selenium + C# stack for this task.

Since I didn't find any articles on this topic in Russian, I will share my experience setting up an environment for developing and debugging automated tests in C# on Linux.

The OS used was Kubuntu 18.04 64-bit with Linux kernel 4.15.0-99-generic, installed from an ISO image downloaded from the official website. I believe any modern and relatively popular Linux distribution will suffice.

For C#, the CLR was the Mono JIT compiler version 6.6.0.166. Its installation consisted of sequentially copying and executing commands in the terminal (in Kubuntu, it's Konsole) from this page.

And as for the IDE used, it was MonoDevelop 7.8.4 (build 2), installed similarly to Mono.

Selenium supports multiple browsers, but I was too lazy to torture myself and limited myself to Activated's, installing the 64-bit .deb package.

Next, we create a solution in MonoDevelop:

launching MonoDevelop
going to the 'File' menu
selecting 'Create Solution'
clicking on '.NET'
choosing 'NUnit Class Library Project' and pressing 'Next'
specifying the name and path of the solution, clicking 'Create'

To control the browser, you will also need a couple of NuGet packages:

we go to the 'Project' menu and select 'Manage NuGet Packages'
search for and install the Selenium.WebDriver package
search for and install the Selenium.WebDriver.ChromeDriver package

That's basically it, all that's left is to write some code to check that everything is set up correctly. When creating a solution, a file for test methods Test.cs is automatically created, into which I placed the following lines of code:

using NUnit.Framework;
using System;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium;

namespace SeleniumTests
{
    [TestFixture()]
    public class Test
    {
        [Test()]
        public void TestCase()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("http://habr.com/");
            Assert.IsTrue(driver.Url.Contains("habr.com"), "Something is wrong =(");
            driver.Quit();
        }
    }
}

Running the test is done from the 'Unit Tests' tab; if it is not displayed, go to the 'View' menu and select 'Test'.

Successful automation =)
