IoT Testing

There are more connected devices than ever before as IoT (Internet of Things) technology is gaining traction. IoT testing is conducted to test IoT technology based devices. The various types of testing for IoT systems are as follows:

Usability Testing – To test the usability of an IoT system

Compatibility Testing – To check the compatibility of devices in IoT system

Reliability & Scalability Testing – Simulation of sensors utilizing virtualization tools

Data Integrity Testing – To validate the integrity of data

Security testing – To validate the user authentication process and data privacy controls

Performance Testing –  To test the performance of the connected devices in an IoT network

Selenium and NUnit framework:

Selenium with NUnit framework allows differentiating between various test classes. NUnit also allows using annotations such as SetUp, Test, and TearDown to perform actions before and after running the test.

NUnit framework can be integrated with Selenium by creating a NUnit test class and running the test class using NUnit framework.

The below are the steps needed to create and run a test class using NUnit framework.

Steps to create a NUnit Test class in Selenium:

Step 1) In the Solution Explorer, Right clicked on project > Add > Class

Step 2) Class creation window will appear

  1. Provide a name to the class
  2. Click on Add button

Step 3) The below screen will appear.

Step 4) Add the following code to the created class. Please note that you need to specify the location of ‘chromdriver.exe’ file during chrome driver initialization.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Chrome;


using NUnit.Framework;
using NUnit.Framework.Interfaces;
using NUnit;

namespace RnD
{
    [TestFixture]
    public class TestDemo1
    {
        public IWebDriver driver;

        [SetUp]
        public void Initialize()
        {
            driver = new ChromeDriver();
        }

        [Test]
        public void BrowserTest()
        {
            driver.Manage().Window.Maximize();
            driver.Navigate().GoToUrl("https://www.google.com/");
        }

        [TearDown]
        public void closeBrowser()
        {
            driver.Close();
        }
    }
}

Step 4) Click on ‘Build’ -> ‘Build Solution’ or keypress ‘Ctrl + Shift + B’

Step 5) Once the build is successful, we need to open the Test Explorer window. Click on Test -> Windows -> Test Explorer

Step 6) Test Explorer window opens with the list of available tests. Right-click on Test Explorer and select Run Selected Tests

Step 7) Selenium must open the browser with specified URL and close the browser. Test case status will be changed to ‘Pass’ on the Test Explorer window.
