The tests are then re-run to ensure an utterly error-free application. Manual testing has its own drawbacks, however, a few of which can include:. Considering all the drawbacks, a desperate need to automate the testing process was in demand.

Now, let us understand the advent of Selenium before looking into what Selenium is. Jason Huggins, an engineer at ThoughtWorks, Chicago, found manual testing repetitive and boring. He developed a JavaScript program to automate the testing of a web application, called JavaScriptTestRunner.

Initially, the new invention was deployed by the employees at Thoughtworks. However, in , it was renamed Selenium and was made open source. Since its inception, Selenium has been a powerful automation testing tool to test various web applications across different platforms.

Selenium is an open-source, automated testing tool used to test web applications across various browsers. Selenium has a dedicated suite that facilitates easy testing of web applications.

Developed by Shinya Kasatani in , Selenium IDE is a browser extension for Firefox or Chrome that automates functionality. Typically, IDE records user interactions on the browser and exports them as a reusable script.

IDE was developed to speed up the creation of automation scripts. IDE ceased to exist in August when Firefox upgraded to a new Firefox 55 version, which no longer supported Selenium IDE. Applitools rewrote the old Selenium IDE and released a new version in The latest version came with several advancements.

Paul Hammant developed Selenium Remote Control RC. Initially, a tool called Selenium-Core was built. It was a set of JavaScript functions that interpreted and executed Selenese commands using the browser's built-in JavaScript interpreter.

Selenium-Core was then injected into the web browser. js used by google. This program can access pages like google. Connect Now. Platform ASPM. Company About Us. Differentiating capabilities:. ADD-ON PRODUCTS. Audio-Visual Platform One Platform For All Your Media Testing.

You can use multiple Dust mites languages Seleniu Metabolic enhancers, CPython, Metabolic enhancers to create Selenium Test Scripts. Testing done using the Selenium testing tool is usually referred to as Selenium Testing. Selenium Software is not just a single tool but a suite of software, each piece catering to different Selenium QA testing needs of an organization. Here is the list of tools. At the moment, Selenium RC and WebDriver are merged into a single framework to form Selenium 2.

Selenium automation testing -

Same Origin policy prohibits JavaScript code from accessing elements from a domain that is different from where it was launched. Example, the HTML code in www.

The same origin policy will only allow randomScript. js to access pages within google. com such as google. However, it cannot access pages from different sites such as yahoo. com because they belong to different domains. This is the reason why prior to Selenium RC, testers needed to install local copies of both Selenium Core a JavaScript program and the web server containing the web application being tested so they would belong to the same domain.

Unfortunately; testers using Selenium Core had to install the whole application under test and the web server on their own local computers because of the restrictions imposed by the same origin policy. This system became known as the Selenium Remote Control or Selenium 1.

Selenium Grid was developed by Patrick Lightbody to address the need of minimizing test execution times as much as possible.

Shinya Kasatani of Japan created Selenium IDE , a Firefox and Chrome extension that can automate the browser through a record-and-playback feature. He came up with this idea to further increase the speed in creating test cases.

He donated Selenium IDE to the Selenium Project in Simon Stewart created WebDriver circa when browsers and web applications were becoming more powerful and more restrictive with JavaScript programs like Selenium Core.

It was the first cross-platform testing framework that could control the browser from the OS level. In , the whole Selenium Team decided to merge WebDriver and Selenium RC to form a more powerful tool called Selenium 2 , with WebDriver being the core.

Currently, Selenium RC is still being developed but only in maintenance mode. The Name Selenium came from a joke that Jason cracked once to his team. Since Selenium is a well-known antidote for Mercury poisoning, Jason suggested that name and his teammates took it.

So that is how we got to call this framework up to the present. Selenium Integrated Development Environment IDE is the simplest framework in the Selenium suite and is the easiest one to learn.

It is a Chrome and Firefox plugin that you can install as easily as you can with other plugins. However, because of its simplicity, Selenium IDE should only be used as a prototyping tool.

If you want to create more advanced test cases, you will need to use either Selenium RC or WebDriver. Selenium RC was the flagship testing framework of the whole Selenium project for a long time.

This is the first automated web testing tool that allows users to use a programming language they prefer. As of version 2. The WebDriver proves to be better than Selenium IDE and Selenium RC in many aspects.

WebDriver, unlike Selenium RC, does not rely on JavaScript for Selenium Automation Testing. It controls the browser by directly communicating with it.

Selenium Grid is a tool used together with Selenium RC to run parallel tests across different machines and different browsers all at the same time. Parallel execution means running multiple tests at once.

Because of their architectural differences, Selenium IDE, Selenium RC, and WebDriver support different sets of browsers and operating environments. Quick Test Professional QTP is a proprietary automated testing tool previously owned by the company Mercury Interactive before Hewlett-Packard acquired it in Its later owner is MicroFocus and the tool is renamed UFT one.

The Selenium Tool Suite has many advantages over QTP as detailed below —. Skip to content. Table of Content:.

Report a Bug. Previous Prev. Next Continue. Finally we update our test cases to search for different terms and verify that the resulting page content contains the web addresses we want to check for.

Each test case uses our new search function to start the search. We then use the assert. isTrue function to tell our testing framework if the test passes or fails.

When you then run the tests with the npm run test command again, Mocha will execute one test case after the other, which will launch a new Chrome browser session and search DuckDuckGo. Each test will verify that the web address we want to check for exists on the result page.

Once all tests have been run, Mocha will print the test results to the console for us to review. To make the test suite even more useful, we can also take screenshots at the end of each test. For this we are adding new code to the afterEach function to take a screenshot of the browser window and save the file to the screenshots sub directory.

You can see the full test. mjs script and our new screenshot code in the repository on GitHub. Submitting and reporting our Selenium test results to a test management tool such as Testmo allows us to track test runs over time, share test results with our team, identify problematic test cases such as slow or flaky tests and improve our test suite.

It also allows us to manage our automated tests together with other testing efforts such as manual test case management or exploratory testing sessions. To report our test results to Testmo, we start by installing the Testmo command line tool. We will again use the NPM package manager for this and commit the updated package config files to our repository:.

So far, our test automation suite prints all test results to the console. To submit our test results to a testing tool, we need a better and more structured way to save our results.

Over the time the JUnit XML file format has become the de facto standard to store and share test automation results. So we will tell Mocha to write our results to such an XML file. Pretty much any test automation tool or framework supports this file format directly or indirectly, so this approach will work with any tool.

When we previously updated our package. json file with additional script aliases, we also added a script called test-junit , which calls Mocha with additional parameters to generate such a file. If you run this script npm run test-junit you can find the newly created result file in the results sub directory.

We can then use the testmo command line tool to upload the results from this file and create a new test run. We just set the Testmo URL and API key first which can be generated from the user profile page in Testmo and specify additional parameters such as the project ID, new test run name, etc.

After the test run has been created in Testmo and the test results have been submitted, we can see all tests and results by accessing the run in Testmo. The run will list all test details such as execution times, test names, passed and failure statuses, assertions etc.

This is what the test results of a run look like in Testmo:. We first started our Selenium automation suite by running Mocha via npm run test-junit , which executed our test cases and wrote the results to an XML file. We then called the testmo command after that to report and submit the results.

But there's a slightly better way to do this. We can call testmo and pass the Mocha test run command as the last parameter instead. The testmo command line tool will then launch our test suite with Mocha itself. This has the added benefit that Testmo can then also capture the full console output of our tests, it can measure the execution time and it can record the exit code which it also passes through by default.

Testmo will then also show all these details along with the test results, so we can see the full console output, for example. We also added a script alias to our package.

json file for this. Simply run npm run test-ci from the command line. This will launch testmo and tell it to run our Mocha tests before uploading the results. We've accomplished our goal of creating a sample Selenium test automation suite for this project and then report the results to a QA tool.

But no Selenium guide can be complete without also looking at Selenium Grid and explain what it is. Remember when we discussed how the Selenium WebDriver binding library connects to a browser driver application such as ChromeDriver to launch and drive a browser? This is what you would often do for a simple local development environment.

To run your tests against different browsers, browser versions or operating systems, you would usually connect to a Selenium Grid setup instead. When you then request a specific browser and browser version, Selenium Grid can launch a browser on a separate node that matches the requested details it also makes it easier to run multiple browsers simultaneously at the same time.

We have actually been using Selenium Grid when we executed our tests for this example project. So when our script connects to selenium , it asked the Selenium Grid instance to launch a Chrome browser session for us. Setting up a full Selenium Grid cluster with multiple nodes is outside of the scope of this article and you don't usually need this in many cases.

But if you are using a third-party cloud service to run your Selenium tests see below , remember that you are likely using and connecting to a Selenium Grid setup to launch and drive browsers.

Here's what this usually looks like:. This is especially useful for Selenium tests, as it can take a long time to run a large browser automation suite and CI platforms make it easy to run multiple tests in parallel. If you want to run your Selenium tests against many different browsers and version combinations, or want to run your tests against platforms that are difficult to host yourself such as macOS or mobile platforms , then it can be useful to use a cloud service for this.

You can learn more about using such services with Testmo with our Sauce Labs test management and BrowserStack test management integrations and we will also have more upcoming code examples and articles for these platforms.

Things are fortunately much easier than they sound and lets start by looking at the basic concepts of Selenium and how it interacts with web browsers: Automation script: It all starts with your automation script. To automate a browser and develop automated tests with Selenium, you start by writing a script in a programming language of your choice.

The language you use doesn't really matter: you can use Selenium with most popular programming languages such as Java, Python, Ruby, C , PHP, JavaScript etc. We recommend using the programming language you are already familiar with. For our article we are going to write our examples in JavaScript Node.

js , but any language will work. Selenium WebDriver : This is the library binding you use with your programming language. It provides various APIs to drive and automate a web browser, such as navigating to a page, clicking buttons, entering text into fields, checking for visible text etc.

This is what most people understand as the core Selenium component they use on a daily basis. Browser driver ChromeDriver, GeckoDriver etc. The above mentioned Selenium WebDriver library uses a specific protocol also called WebDriver to talk to browsers. The library doesn't talk to the browser directly though.

Instead, browser vendors provide a small driver application to connect to. The driver application then actually implements the browser automation. The drivers are named differently for different browsers.

For example, Google calls their driver application for Chrome ChromeDriver. For Firefox, Mozilla provides an application called GeckoDriver. Then there's SafariDriver from Apple, EdgeDriver from Microsoft etc. The important thing you need to know is that you need to run the relevant driver for your browser if you want to automate it we will look at this below.

Basic Selenium components and how everything fits together. Setting Up Selenium Environment There are different options to get started with Selenium development and to set up the local development environment. Watching the browser activity inside the Selenium container via VNC.
