What are Automation Scripts?

Introduction

What are Automation Scripts? Automation is becoming a crucial technique in the field of software testing to increase accuracy and efficiency. Selenium is a well-liked option for testing web applications out of all the available automation frameworks. The idea of automation scripts is at the heart of Selenium automation.

In this article we will aim to explain the function, design, and advantages of automation scripts in the context of Selenium automation testing. When discussing automation scripts in the context of Selenium testing, programming languages like Java, Python, or C# are used to create a collection of directives and commands.

These scripts engage with the web application that is being tested, simulating user activities and confirming anticipated results. Automation scripts serve as a link between the web application and the testing tool (Selenium), allowing for speedy and trustworthy testing by automating tedious operations.

Structure of automation scripts

Selenium testing automation scripts are organized and structured in a methodical manner. Clarity, maintainability, and reusability are all guaranteed by a well-structured automation script. The primary elements and the functions they play within the framework of automation scripts are broken down as follows:

1. Test Setup: The set-up procedures required before running the test cases are included in this component. Launching the browser, setting needed capabilities, and initializing the Selenium WebDriver may all be necessary.
2. Test Data: The input numbers or parameters needed to run test cases are referred to as test data. It may be kept in the script itself or fetched from external databases or spreadsheets. Flexibility and scalability in test automation are guaranteed by good test data management.
3. Page Objects: The web elements and associated methods are represented on a web page by page objects. They include the operations and communications that take place on a particular page or application component. Page objects enable the modularity, reuse, and simpler maintenance of automation programs.
4. Test Steps: The actions carried out on the web application during test steps serve to mimic user interactions. Finding online items, interacting with them (clicking buttons, typing text, and selecting options), and moving between sites are all included in this process. To carry out these test phases, Selenium offers numerous techniques and APIs, assuring precise user action model.
5. Assertions and Verification: The anticipated results of test phases are validated using assertions and verifications. They include comparing actual results to expectations or analyzing particular circumstances. Assertions provide information on the behavior of the application by assisting in the identification of any inconsistencies or errors during test execution.
6. Error Handling: Mechanisms for handling errors are essential for gently handling exceptions or unforeseen circumstances. To record and handle errors when running tests, try-catch blocks or exception handling strategies can be used. The automation script is guaranteed to continue running or to stop gracefully without causing disturbances through proper error handling.
7. Reporting and Logging: The complete documenting of test execution and results is made possible through reporting and logging. They consist of producing reports with test summaries, screenshots, and logging pertinent data. Reports that are in-depth help with test analysis, bug fixing, and stakeholder communication.

How to Write Automation Scripts Using Selenium?

In order to write your automation scripts using Selenium, you will need to follow a few key steps as detailed below:

1. Set up you Dev-environment:

Begin by installing an Integrated Development Environment (IDE) like Eclipse or IntelliJ for Java, or PyCharm for Python. You can then install the Selenium WebDriver library for your choice of programming language using package managers such as pip (Python), or Maven/Gradle (Java). Next, download an appropriate WebDriver that is executable for the browser you wish to automate. It is important to note that the WebDriver version also matches your browser version.

2. Setup a new project:

You will now need to set up a new Project in your IDE, or simply create a new script file. Then, begin by importing the necessary Selenium WebDriver classes and any additional libraries you might need, such as logging libraries. These include log4j (Java) or logging (Python), and help in capturing useful information for debugging assistance. Other libraries include reporting libraries and assertion libraries. these are used for generating comprehensive and visually appealing reports of your test execution, and improving error messages for better result analysis respectively.

3. Initialize WebDriver and navigate to Webpage:

Next, create an instance of the WebDriver class corresponding to the browser that you want to automate; if needed also specify the WebDriver executable path. In rare cases you might also need to configure any desired options such as setting the setting the browser window size, and enabling or disabling the notifications. Then, use the WebDriver instance to navigate to a specific URL or webpage using ‘get()’ method.

4. Interact with Web elements:

You can now use the WebDriver instance to locate and interact with various web elements such as buttons, input fields, checkboxes, etc. Proceed ahead to verify the expected behavior of the web application.

5. Manage browser windows and execute:

In case your web application uses multiple windows or frames switch between them using ‘switchTo()’ method. Then run your script and inspect for any error messages.

6. Cleanup and close WebDriver:

Once the automation script is complete, make sure to close the WebDriver instance to release resources and close the browser.

Benefits of Automation Scripts in Selenium Testing
