For any website or app to succeed in the digital market, it is essential to offer a bug-free user experience across all platforms, browsers, and operating systems. Before making an application available to users, application testing assists developers in locating and resolving errors in the application’s code.
However, when websites and apps have advanced features, manual testing becomes a time-consuming, challenging, and complicated task. Repetitive tests, such as regression and integration tests, are usually left to machines because they are more prone to human error.
Since thorough testing is necessary for efficient application operation, automation makes testers’ lives easier by allowing them to manually test only what is necessary Along with extending coverage and offering more accurate results, automation testing significantly shortens the time it takes to market while improving application quality.
We will cover 10 essential tips for successful Selenium WebDriver testing in this article. Let’s first discuss what Selenium testing and automated testing are before moving on.
Automation testing is the use of a tool to automate a developer’s or tester’s repetitive manual testing process. The execution of several test scenarios can be accelerated by automation testing by executing them in parallel and repeatedly without the need for human interaction, to verify that the outcomes generated by particular processes or lines of code correspond to the desired outcomes.
Human error can occur during manual testing, whereas automated testing can easily run thousands of complex test cases by following the same processes each time. This increases coverage and guarantees that all application features are thoroughly and consistently tested. Once developed, automated testing can be used periodically during various stages of the application development lifecycle.
However, to get results, automation testing necessitates the use of numerous tool sets, test automation frameworks, and technical expertise. Selenium is one of those tools.
After understanding automation testing, let’s take a quick look at Selenium and its most popular component, Selenium WebDriver.
Selenium is a robust and well-known open-source automated testing framework that enables the creation of scripts for automated web browser testing. Selenium’s adaptability is one of the key factors contributing to its popularity. It can be used for numerous purposes, including load testing, functional testing, and regression testing.
Internet Explorer, Firefox, Chrome, and Opera are just a few of the browsers that Selenium can automate testing on. Additionally, Java, C#, Ruby, and Python are among the many programming languages that Selenium supports. This makes Selenium a desirable choice for developers and testers who specialize in several languages.
Selenium is made up of three primary components that help with testing rather than being just a single tool. Among the set of tools, Selenium WebDriver is the most widely used component of Selenium among testers and developers.
Selenium Web Driver is one of the most used test automation frameworks for web automation. It is an open-source library that comes with an extensive set of capabilities that let developers build custom code in a variety of programming languages, including Java, C#, Python, and Perl, and communicate with the browser of their choosing using browser-specific drivers.
Its API communicates directly with the real browser and activates the automation test that the tester created with the browser’s built-in features. JSONWireProtocol is the protocol that WebDriver utilizes to connect with browsers. Together, these features make it the ideal tool for automation.
Additionally, it has several fabulous features including the ability to capture test results and automatically find elements on webpages. Selenium Client Libraries, JSON Wire Protocol, Browser Drivers, and Browsers are the four main building components that makeup Selenium WebDriver.
Although there are no hard and fast rules for efficient Selenium testing, there are some tips developers may use to get the most out of it and set up reliable, exhaustive, and successful data-intensive tests. Testers may organize and run Selenium tests as efficiently as possible and get the most out of their Selenium WebDriver Testing efforts by following the tips provided below.
These tips will help enhance Selenium testing abilities and improve test findings.
Web applications can take some time to load because of network issues, server problems, or several other factors. An effective solution to this is to pause the scripts and wait for all the items to load. The thread.sleep() function can be used to stop the test script for a specified amount of time. But this function has a major problem. For instance, a web page may occasionally take longer to load than expected or load significantly faster on occasion.
Testers may have wasted a significant amount of time executing Selenium test automation in the faster cases, whereas, in the slower ones, they would have received a failure as a result. Developers must therefore use implicit or explicit waits to prevent these occurrences.
Sleep is less efficient in handling delays than Selenium’s implicit and explicit wait. They permit the test to pause for a set period until a particular condition is met before resuming.
Implicit wait instructs the browser to wait for a specific amount of time for all of the web elements available on the page, ensuring that the test runs smoothly and preventing unnecessary failures brought on by timing difficulties. The next line of code is executed if the element becomes available sooner than the implicit delay time.
For speedy and effective results, Selenium automated testing uses the parallel testing technique. Selenium is a fantastic tool for reducing the time it takes to run automated tests and for spreading out the workload across several machines.
It permits executing many test cases concurrently on various browsers, operating systems, or devices, reducing the total time the test suite takes to run and increasing the effectiveness of the testing procedure.
Making a thorough report is a crucial component of automation testing. The automation testing report reduces the time needed to maintain the test data and helps to make test findings easier to understand. Finding the error-prone test case can be difficult if a specific test in a large test suite fails.
Selenium WebDriver has methods to provide reporting systems in such conditions. By managing the test data in an organized way, its report creation can console logs at specific places in the test code aiding with a better understanding of the code, tracing errors, saving valuable time, and improving the overall efficiency of the application. As a result, developers have better control over tests and can analyze when test scripts are failing, which aids in limiting the issue.
When writing Selenium automation tests, following good naming conventions is essential. The development and Selenium testing processes can be made more efficient by establishing uniform naming standards for every type of file created.
The code is easier to read and maintain when its elements, methods, and variables are appropriately named. It’s critical to select names that are relevant, descriptive, and appropriately convey the function and purpose of the corresponding component, to prevent the working teams from wasting time scrolling through the implementation each time they run the same test.
Data-driven testing is a powerful automated testing technique that enables the execution of the same test script repeatedly with various input data sets. The dataset is better kept separate from the test code using data-driven frameworks.
Data-driven testing is frequently used in Selenium WebDriver testing to test web applications against multiple combinations of browsers, devices, and operating systems with varied data combinations, hence assisting in ensuring the application’s reliability and stability in different scenarios. Developers can save time and effort by implementing data-driven testing because they only need to build the test script once and then run it against several data sets.
Selenium WebDriver testing frequently makes use of the Page Object Model (POM), a design structure that offers numerous benefits for streamlining test maintenance, increasing code reuse, and minimizing code duplication.
Every webpage in POM has its page class, which may be used to discover web elements on the page as well as page methods for these web elements. The POM encourages better code organization and helps to maintain the code in a structured and more readable manner by isolating the test cases from the specifics of the UI elements.
Because of this design pattern, it is simple to maintain the test code. The developer can rapidly make changes to the UI elements in the associated page class without having to dig through the entire code.
The maintainability, effectiveness, and testing speed of Selenium WebDriver testing are improved by using shorter, and reusable code. Developers can write code once and utilize it across various test cases when they employ reusable code, which minimizes the amount of code duplication and facilitates upgrades and changes. Since debugging in long codes is time-consuming, the shorter code makes it simpler to detect problems and errors.
Without a doubt, Selenium offers an extensive set of selectors to increase the flexibility of test scripts. But not all work quickly and efficiently. But CSS selectors can accelerate testing. They are frequently used to navigate to and interact with components on web pages.
CSS selectors offer a strong and flexible method for locating and choosing items based on their unique qualities and traits. By mentioning the element’s CSS selector in the code, Selenium developers can quickly target particular items on a web page, such as buttons, links, text fields, or dropdown menus.
Selenium WebDriver testing requires the use of debugging tools. For finding and fixing code problems, debugging tools are crucial. It’s critical to foresee and address potential issues that may occur during the execution of automated tests. These tools assist testers in efficiently debugging the code and locating faults in their specific locations. As a result, tests will not fail due to unexpected issues, and feedback will be more precise and useful.
When a user encounters a pop-up window while surfing a website, these notifications may occasionally draw their focus away from already open windows towards newly opened windows. However, they can readily deal with pop-up windows simply by reading the notification and responding accordingly.
However, it causes discomfort when running automated tests. Fortunately, addressing browser pop-ups is supported automatically by Selenium. Switch_to_alert(), a feature of Selenium, aids in shifting emphasis to a recently launched browser window. The user has the option to fill it out, accept it, or close it.
To make use of the information above, testers should pick a Selenium-based platform that supports automated testing. This will allow them to plan tests, oversee their execution, and easily and quickly provide complete reports.
Selenium is supported by the cloud-based automated testing platform LambdaTest, which also supports all other well-known test frameworks. It enables testers to run manual and automated tests for web and mobile applications on a cloud Selenium Grid comprising more than 3000 real devices, browsers, and operating system combinations online. The Grid can also be used to accelerate the execution of parallel tests, allowing for faster results while maintaining accuracy.
LambdaTest makes testing easier for testers by giving them access to a full suite of testing features, including data-driven testing, cross-browser testing, and parallel testing. It also includes manual exploratory testing with the ability to automate Web, Android, iOS, and API testing, website testing, and mobile application testing all on one platform.
With the help of LambdaTest’s built-in development tools, integrations with well-known CI/CD systems like Jenkins, CircleCI, etc., and well-liked programming languages and frameworks, automated testing is made easier, streamlined, and more result-oriented.
The process of application testing can be accelerated with the help of Selenium WebDriver, an excellent test automation tool. Effective testing using Selenium WebDriver is essential. If testers follow the above essential tips, they will be able to run Selenium tests more quickly and efficiently. This will enable them to increase the quality of the applications they test and execute them more efficiently.
