Optimizing Selenium Test Cases by Reducing Duplication

Optimizing Selenium Test Cases by Reducing Duplication

16 July 2024 Stephan Petzl Leave a comment QA

When developing automated tests with Selenium, a common challenge is maintaining the login process across multiple test cases. This can lead to redundant code and increased maintenance efforts. In this guide, we will explore effective strategies to keep your tests DRY (Don’t Repeat Yourself) and maintainable.

Understanding the Problem

In Selenium testing, each test case often starts with a login procedure. If the login credentials change, you would need to update each test case individually. This redundancy can be cumbersome and error-prone.

Solution: Refactoring for Reusability

To address this issue, you can refactor your tests to isolate the login procedure into a reusable method. Here are some approaches to achieve this:

1. Use Page Objects

The Page Object Model (POM) is a design pattern that helps create object-oriented classes for web pages. This allows you to encapsulate the login logic in a single class.

For more information on implementing Page Objects, refer to our detailed guide on Page Objects in Selenium.

2. Abstract Classes

Another approach is to use an abstract class that contains the login method. This method can be called at the beginning of each test case. Here’s a sample implementation:

protected void getBaseURLAndLoginTestUser() throws Exception {
    driver.get(BASE_URL);
    WebElement userName = findElementById("j_username");
    userName.clear();
    userName.sendKeys("testing1");
    WebElement password = findElementById("j_password");
    password.clear();
    password.sendKeys("testing1");
    WebElement loginButton = findElementById("modalDialogButton");
    loginButton.click();
}
            

This method can then be invoked in your test setup:

public class NameOfClass extends AbstractClass {
    @Override
    @BeforeClass
    public void setup() throws Exception {
        super.setup();
    }
}
            

3. Modular Test Actions

Modularizing your test actions by breaking them down into reusable steps can also help. For instance, you can define a login action and call it in different test cases.
