Exploring the Power of Collections in Automation Testing

Let's shed some light on how collections enhance our testing endeavors.

?A "collection" typically refers to a group or collection of web elements that share certain attributes or characteristics. These collections are used to interact with multiple web elements that match specific criteria. The primary purpose of using collections in Selenium is to perform actions on multiple elements simultaneously, which can be more efficient than interacting with each element individually.

Using collections is useful when you need to work with multiple similar elements on a web page, such as links, buttons, or checkboxes. It helps in reducing code redundancy and making your test automation scripts more efficient and maintainable.

??? Why Are Collections Important in Automation Testing?

Collections, such as arrays, lists, and dictionaries, are essential tools for managing test data, handling dynamic elements, and streamlining repetitive tasks. They allow testers to:

1. ?Store Test Data: Collections are a great way to store and manage test data. Whether it's a list of usernames and passwords or a set of test cases, collections keep your data organized and accessible.
2. Iterate Through Elements: Automation often involves interacting with multiple elements. Collections make it easy to iterate through web elements, perform actions, and validate results.
3. Dynamic Element Handling: In dynamic web applications, locators can change. Collections help maintain flexibility by adapting to different elements on the page.
4. Parameterization: Use collections for parameterization, where test data can be read from a data source and injected into test scripts, enabling data-driven testing.
5. Test Data Management: Collections allow you to efficiently manage various sets of test data, making it easier to run the same test with different inputs.

?Here are some common scenarios where collections are used:

• ?Finding Multiple Web Elements: When you need to find multiple elements that share the same locator, you can use findElements to return a list of web elements. For example:

List<WebElement> links = driver.findElements(By.tagName("a"));        

• Iterating Through Elements: You can iterate through a collection of web elements to perform actions on each of them. For instance, clicking on a list of links:

for(WebElement link : links) { link.click(); }        

• Checking Element Presence: You can use collections to check if an element is present or absent. For example, checking if a list of elements contains a specific text:

booleancontainsText=links.stream().anyMatch(link -> link.getText().equals("Your Text"));        

• Storing Element Attributes: You can store and analyze attributes of multiple elements in a collection. This can be useful for data validation. For example, storing the href attributes of multiple links:

List<String> hrefs = links.stream().map(link -> link.getAttribute("href")).collect(Collectors.toList());        

• Filtering Elements: You can filter a collection of elements to work with a subset that meets certain criteria. For example, filtering a list of input elements to get only enabled ones:

List<WebElement> enabledInputs = driver.findElements(By.tagName("input")) .stream() .filter(input -> input.isEnabled()) .collect(Collectors.toList());        

• Working with Sets: Selenium also provides methods like findElements to return a Set of web elements, which ensures that each element is unique. This can be useful when dealing with lists of distinct elements like checkboxes.
• Handling Dropdowns: When working with dropdowns (select elements), you can use collections to manage the options within the dropdown. You can select options, get selected options, or verify the options present in the dropdown.
• Validating Tables: Collections can be used to work with tables on web pages. You can extract table data, iterate through rows and columns, and perform data verification or extraction tasks.
• Verifying Page Titles: You can collect all the page titles in different tabs/windows and switch between them. This is useful when working with multiple browser tabs.

?In the ever-evolving world of automation testing, collections are a key tool that helps us achieve efficiency, maintainability, and flexibility in our testing efforts. When used wisely, they can save time and ensure the reliability of our automated tests. ????
