Handling Dynamic Tables with Changing Rows and Columns

Finding the rows and columns based on their dynamic changes and determining the table structure are necessary when working with dynamic tables in Selenium. To explain the scenario I use a Demo site.

@Test
public void dynamicTableHandling(){
    WebDriver driver = new ChromeDriver();
    driver.manage().window().maximize();
    driver.get("https://practice.expandtesting.com/dynamic-table");
    List<WebElement> Raws =  driver.findElements(By.xpath("//table[@class='table table-striped']/tbody/tr"));
    System.out.println("The no. of raws : "+Raws.size());

    for(int r=1;r<=Raws.size();r++){
        WebElement name = driver.findElement(By.xpath("//table[@class='table table-striped']/tbody/tr["+r+"]/td[1]"));
        if(name.getText().equals("Chrome"))
        {
            String CPULoad = driver.findElement(By.xpath("//td[text()='Chrome']//following-sibling::*[contains(text(),\"%\")]")).getText();
            System.out.println(CPULoad);
            String Value = driver.findElement(By.id("chrome-cpu")).getText();
            System.out.println(Value);
            if(Value.contains(CPULoad)){
                System.out.println("The CPU Load is equal");
            }
            else{
                System.out.println("The CPU Load is not equal");
            }
            break;
        }

    }
    driver.quit();

}

Here's how to use Java's Selenium WebDriver to manage a dynamic table with shifting rows and columns:

Code Explanation:

As the first step I did setup the driver and navigate to the Demo site.In that case I have Initialized a WebDriver instance (ChromeDriver) and Maximized the browser window and navigates to the given URL.

After that locates all rows in the table using the XPath.

//table[@class='table table-striped']/tbody/tr.

Then prints the total number of rows.

Next Iterated Through Rows using for Loop , through each row using an index (r)and extracted the name in the first column using XPath.

And I checked whether If the name in the first column matches "Chrome", then finds the CPU Load percentage dynamically using

//td[text()='Chrome']//following-sibling::*[contains(text(),\"%\")].

After that retrieved the CPU Load value from a specific element with ID chrome-cpu and compared the two values and prints a message about their equality. Finally Quits the browser after the test.
