Are you a new software tester trying to utilize the full potential of Selenium Java? This is the perfect article for you. We will help you explore the essential tips for creating highly efficient test cases using Java programming.
In the current software testing industry, Selenium holds the crown for being the most popular open-source framework that helps testers automate web app testing. This test suite supports multiple programming languages, including the highly popular Java.
By combining Java with Selenium, the developers will have access to an efficient and massively robust way of creating automated web app test cases. However, the developers must increase their knowledge beyond basic understanding to utilize the full potential of Selenium Java.
Tips for Efficient Use of Selenium Java
Let us now go through some of the most efficient tips that can help the testers properly set up the testing environment and also utilize the full capabilities of automated Selenium testing and the Java programming language:
1. Setting Up The Environment
Before understanding the advanced tips for Selenium testing with Java, we must understand how the testers can set up the testing environment. This is because the proper setup of the app testing environment also plays a massive role in the overall test efficiency:
- The first step involves installing the latest version of the Java Development Kit. The testers can easily download this software from the official Oracle website.
- Finished installing JDK? Divert their focus towards downloading the Selenium WebDriver Java bindings, which are also available on the official Selenium website.
- Next, the testers have to use Maven, which, in turn, is a powerful build automation tool. This is mainly used while working on Java-based application testing projects. To use Maven, the developers must create a new project and add the Selenium dependency in the “pom.xml” file. The following code snippet will allow the testers to perform this process:
2. Writing Maintainable and Readable Test Cases
Now, the testers have to divert their focus towards writing readable and maintainable suits. This practice is very important to maintain the efficiency of Selenium testing. Using the following tips, the developers can improve the efficiency and the maintainability of the test cases:
- We recommend that testers implement Page Object Models, a design pattern to create an object repository for web elements. Using this approach, testers can improve maintenance and reduce the possibility of code duplication. In this approach, a class represents each page of the web app, and the elements on the page are presented as variables.
- We also encourage using descriptive names for the test methods and variables. Use this approach to not only identify the test cases but also make them easy to understand, even for the non-technical members of the team.
3. Using Efficient Element Locators
The testers must realize that it is highly important to choose the right locators for web elements to increase the testing stability and the speed of the test execution process.
It is a common idea that CSS selectors are much faster and more readable than XPath. So, we recommend the testers use XPath only when they can’t achieve the goal while using CSS selectors.
If you use indexes in locators, you will realize the test cases become more and more fragile. On the other hand, if the structure of the HTML changes, the test cases might break in the middle of the execution process. So, we advise the testers to use more stable attributes like ‘name’ or ‘ID.’
4. Test Synchronization
Maintaining the synchronization between the test cases is crucial for handling dynamic web elements and avoiding flaky test suites. Selenium has various native offerings to implement waits and improve test synchronization:
- The testers can use implicit waits as the default time between two consecutive testing steps across the entire test script. Implicit wait is the best practice for pausing the test suite before the required element or web page becomes visible. The following code snippet allows the inclusion of implicit wait in Selenium testing:
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
- On the other hand, the testers can also use explicit waits for a specific condition to be met. After this condition is met, the testing scenario will automatically proceed with the next step as predefined in the test plan. To implement explicit wait, the app testers have to enter the following code snippet in the terminal window:
- Finally, Selenium also offers a third waiting mechanism known as fluent waits. Fluent waits are nothing but a combination of explicit wait and periodic polling. Using the following code snippet, the application testers can integrate fluid waits in the Selenium terminal window:
5. Handling Browser Interactions
It is very important for the testers to effectively handle the browser interactions to maintain the efficiency and stability of the Selenium test cases.
Selenium’s ‘window handles’ method will allow the testers to handle multiple browser windows or tabs at the same time. Using the following code snippet, the application developers will be able to utilize the capabilities of this method:
The testers can also handle JavaScript alerts, prompts, and confirmations using the native alert interface with Selenium.
6. Utilizing Test Frameworks
The tests can utilize the capabilities of various test frameworks like JUnit and TestNG to enhance the efficiency of the Selenium test cases. These test frameworks also help improve the test data management and execution process.
We will start our discussion with TestNG, a powerful testing framework that wNUnit and JUnit inspire. Using TestNG, the testers will have access to annotations, data-driven testing, parallel execution, and many more advanced features in the palm of their hands.
To further explain the working process of TestNG, we have mentioned a code snippet for performing automated testing with TestNG and Selenium:
On the other hand, JUnit is yet another well-known testing framework in the modern application development and testing industry. The main selling point of this framework is its straightforward approach and easy integration with multiple application development tools.
Using the following code snippet, the application testers can easily integrate JUnit with Selenium and perform the automated web test cases:
7. Parallel Test Execution
Considering the thousands of components present in modern apps, it is highly important to integrate parallel test execution with Selenium Java. Implementing this practice will significantly reduce the overall test execution time. The testers can use both JUnit and TestNG for this purpose.
To configure parallel test execution with TestNG, the developers must set the required parameters in the ‘testing.xml’ file. We have mentioned the required code snippet to allow the testers to implement this process.
On the other hand, if you are using JUnit testing, you can integrate parallel test execution using the ‘@Parameterized’ and ‘@RunWith’ annotations. Using the following code snippet, the app developers can initiate parallel test execution with JUnit.
Alternatively, LambdaTest is a cloud platform that can also integrate parallel test execution on more than 3000 different combinations of real devices, operating systems, and browser versions. LambdaTest is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale. LambdaTest also allows the testers to integrate JUnit testing with Selenium testing to reduce build times.
8. Integrating With CI/CD Pipelines
We advise the testers to integrate the Selenium Java test cases with continuous integration and deployment pipelines. By implementing this approach, testers can ensure the test cases can automatically run whenever there is any change to the application source code.
The first approach to implementing this process is integrating Jenkins, a popular CI/CD tool. To integrate Selenium testing and Jenkins, the testers can either use a Jenkins file or directly implement it through the Jenkins user interface.
To shed more light on the integration process, we have mentioned a sample code snippet that will assist in this process:
The developers can also integrate continuously and deploy using GitHub actions. Using the following code snippet, the application testers can set up a powerful workflow in GitHub to run the Selenium test cases with every code commit:
9. Handling Advanced Scenarios
While running the Selenium test cases with Java, it is very common that you will come across various advanced scenarios like handling frames, performing actions, and uploading or downloading files. So, to avoid the challenges of this process, we have created a list of some of the most efficient tips that will help you in this regard:
- The testers can use the ‘sendKeys’ method to handle the file upload process. Using the following code snippet, the application testers can implement this method within the terminal window of Selenium:
- On the other hand, the testers can also switch to frames using the ‘switch’ method and easily handle the frames that might be present on the web application or multiple web pages. The testers must simply enter the following code snippet in the Selenium terminal window to implement this method while testing the web frames.
- Finally, the testers can use the ‘Actions’ class that comes natively with Selenium to perform multiple user interactions. These interactions might include clicking on certain web application elements, filling out forms, or navigating the user interface. To spread more awareness about this process, we have mentioned a sample code snippet for the same:
While handling multiple advanced scenarios, we advise the testers to be prepared for various bugs and errors that might arise during the code execution process. So, it is very important to keep track of the entire test execution process and maintain references for previously known errors.
