Selenium Protractor tutorial: How to Run Your First Test on Cloud


    In today’s fast-paced web development environment, user experience is at the core of success. Today’s users access web applications and websites through a wide range of devices, web browsers, and OSes. Ensuring that your digital creations work seamlessly and seamlessly across these diverse platforms has become mission-critical.This is where the power of Selenium’s capabilities comes into play. It’s shaking up the entire way developers and quality assurance (QA) professionals approach testing from start to finish.

    One of the most popular plug-ins for automating testing, especially for Angular applications, is SeleniumProtractor. Built on top of the popular SeleniumWebDriver, SeleniumProtractor supports Angular’s asynchronous operations, as well as its robust interaction with web elements. This makes it an excellent choice for testing complex UI’s and dynamic content in today’s web applications.But SeleniumProtractor isn’t just good for Angular apps, it’s also great for testing non-angular web applications.

    Amidst this testing revolution, the advent of cloud computing has revolutionised the way tests are planned and executed. The days of setting up and running an internal test infrastructure are quickly being replaced by the ease and scalability of a cloud-based testing platform. Cloud-based testing platforms provide virtualized environments with a wide range of browser, operating system, and device combinations. This allows developers to test their applications across a wide range of real-world environments, without the hassle of managing hardware and configurations.

    Running Selenium Protractor tests on cloud infrastructure offers a host of compelling advantages


    Cloud platforms make it easy to scale up or down testing resources depending on what’s needed. Whether you just need to run one test or a whole suite, cloud computing’s flexibility means you can get the most out of your resources.

    Scalability is at the core of cloud computing, and it’s what makes it so useful for software developers and testers alike. When it comes to automated testing in Selenium Proctor, scalability means that cloud platforms can quickly and easily adjust the amount of testing resources to meet different needs. This kind of fluid and dynamic resource allocation has a lot of advantages that make the testing process more efficient and effective.

    Scalability makes sure that tests are running at their best, no matter how big or small they are. If you have a lot of tests running at the same time, your cloud platform will make sure you don’t run out of resources, so you don’t have to worry about running too many tests at once.

    Cost Efficiency

    Cloud scalability is in line with the “pay-per-use” nature of cloud services, where resources are allocated based on demand. This means that you’re only charged for the resources you’re actually using. In periods of low demand, those resources are automatically scaled down, resulting in cost efficiencies. This is especially important for businesses that face variable testing requirements throughout the development life cycle.

    With cloud-based testing, there’s no need for large upfront hardware and maintenance investments. You’re paying for what you actually use, making cloud-based testing an affordable option for businesses of any size.

    Parallel Testing

    One of the biggest benefits of cloud-based scalability is that you can run tests on multiple virtual machines at the same time. With traditional setup, you might only be able to run tests on one physical or virtual machine at a time, which could mean you’re only able to run one test at a time and it could take a while to finish. But with cloud platforms, you can run your test suites on multiple virtual machines all at once, which means you don’t have to wait as long to finish testing cycles.

    Peak Load Handling

    When you’re testing something out before it’s released, or when there’s a lot of people on the internet, your app might get hit with a lot of traffic. With cloud scalability, you can quickly scale up your resources to simulate real-world usage scenarios. This helps you spot performance issues and potential issues under pressure, so you can make sure your app can handle the traffic you’re expecting.

    Global Accessibility

    The concept of scalability encompasses not only the utilisation of resources, but also the distribution of resources. Cloud platforms are capable of deploying resources across multiple geographic regions, allowing for the implementation of tests from various locations to replicate user experiences across the globe.

    This is of particular importance for applications that have a worldwide user base. With cloud-based platforms, teams can conduct tests from any location with access to the internet, which is especially beneficial for distributed teams or remote work environments.


    With a wide selection of browsers and platform options available, you can quickly assess the performance of your application in a variety of settings, including different browser versions and operating systems.

    Reduced infrastructure management

    You don’t have to worry about setting up and managing your testing infrastructure, since it’s all taken care of by the cloud service provider. This means your team can focus on the real work of testing and development.

    By combining Selenium Protractor’s features with the advantages of cloud testing, developers can make their testing processes much more efficient. This synergy helps web apps not only get built faster, but also get released with more assurance that they’re up to date and compatible with other web technologies.

    As web technologies keep changing, combining Protractor with cloud testing is going to be a must-have for creating amazing digital experiences in the ever-changing world of web development. Executing your first Selenium Protractor test on the cloud involves a series of steps that ensure a seamless and efficient testing experience. This comprehensive process covers everything from setting up your test environment to analysing the test results.

    Let’s delve into each step in detail:

    1.Choose a Cloud Testing Platform

    If you’re looking to test your app, it’s important to pick the right cloud testing platform for your project. There are lots of options out there, like Sauce Labs and BrowserStack, as well as CrossBrowserTesting and LambdaTest, so you can find the one that works best for you. Plus, you can choose from a variety of browsers, operating systems, and devices to test your app on.

    2.Set Up Your Protractor Project

    Make sure your Protractor project is up and running and that your test scripts are ready to go. If you’re just getting started with Protractor, you might want to consider writing a simple test script that will take you to a web page and interact with some of the elements on the page. Ensure that your Conf.js configuration is set up properly so that your tests can run. This includes specifying where your test scripts will be located, setting browser preferences, and other important settings.

    3.Obtain Cloud Service Credentials

    Once you have registered for the cloud testing platform of your choice, you will be provided with a set of unique credentials, including API keys or access tokens, which are necessary for the communication of Protractor tests with the cloud infrastructures. These credentials should be stored in a secure manner and should not be hardcoded in test scripts.

    4.Update Protractor Configuration for Cloud Execution

    The configuration file for the conf.js application should be modified to include the capabilities section. This section should be used to specify the desired cloud testing environment settings, such as the browser, version and operating system, as well as additional options such as test timeouts and report formats. The specifics of these settings will vary depending upon the cloud platform being used.

    5. Configure Cloud Service Connection

    In order to facilitate the integration of Protractor tests with the cloud platform, the connection must be configured. This typically requires the use of environment variables, or configuration files, to provide the cloud service credentials associated with the tests. This ensures that the test scripts are able to access the cloud infrastructure in a secure manner.

    6.Run Your Test on the Cloud

    Run Protractor on the cloud by opening a terminal or command prompt and entering the Protractor command. This command usually contains the info you need to get the Conf.js configuration file up and running. Protractor will talk to the cloud service, get the browser and environment running, and get your test scripts up and running.

    7. Monitor Test Execution

    During the execution of the test, users can observe the progress of the process through the dashboard provided by the cloud-based testing platform. This dashboard offers up-to-date information on the state of the test, as well as detailed data regarding the testing environment, images, videos, and any mistakes made.

    8. Analyse Test Results

    Once the trial is finished, you can access the comprehensive reports created by the cloud. These reports contain all the details of the test, such as the pass/fail rate, the logs, images, and performance measurements. You can then analyse the results to determine if there are any problems, like broken features or differences in rendering between browsers and platforms.

    9. Iterate and Refine

    Based on the results of the tests, adjust the test scripts and settings accordingly. Additionally, make any necessary changes to the application code to resolve the problems identified by the tests.

    10. Repeat for Multiple Scenarios

    As you get more comfortable with cloud testing, keep repeating the steps for different test cases. Test your app on different web browsers, phones, and computers to make sure it works well and is compatible.
