Question

I have a method where i have taken the rowcount of 10 records on page load and 15 records after changing the page no to 15 question here is how to validate by creating a Assert method seperatly in order to validate the count

Below is my method:

    public void pagenation()
{

    List<WebElement> noofrowbefore = driver.findElements(By.xpath("//table/tbody/tr/td[1]/p"));
    int beforecount = noofrowbefore.size();
    for(int i=0;i<noofrowbefore.size();i++)
        JavascriptExecutor js = (JavascriptExecutor)driver;
    js.executeScript("window.scrollBy(0,2500)");

    elementInteraction.onClick(pagedropdown);
    wait.until(ExpectedConditions.visibilityOfElementLocated(pagenumberselection));
    elementInteraction.onClick(pagenumberselection);
  //after selecting  the pagenumber need to validate the number of records in the grid
    List<WebElement> noofrowAfter = driver.findElements(By.xpath("//table/tbody/tr/td[1]/p"));
    int aftercount = noofrowAfter.size();
}

Any inputs..

To validate the count of records before and after changing the page number, you can create a separate Assert method. Here's an example of how you can modify your code to include the Assert method:

import org.testng.Assert;

public void pagination() {
    List<WebElement> noOfRowsBefore = driver.findElements(By.xpath("//table/tbody/tr/td[1]/p"));
    int beforeCount = noOfRowsBefore.size();

    // Scroll down the page
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("window.scrollBy(0,2500)");

    elementInteraction.onClick(pagedropdown);
    wait.until(ExpectedConditions.visibilityOfElementLocated(pagenumberselection));
    elementInteraction.onClick(pagenumberselection);

    // Wait for the page to load with new records
    // Add necessary wait condition here if required

    List<WebElement> noOfRowsAfter = driver.findElements(By.xpath("//table/tbody/tr/td[1]/p"));
    int afterCount = noOfRowsAfter.size();

    // Assertion
    Assert.assertEquals(afterCount, beforeCount + 5, "Number of records is not as expected after changing the page number.");
}

In this example, I have used the assertEquals method from TestNG's Assert class to compare the count of records before and after changing the page number. The expected count after changing the page number is beforeCount + 5, assuming each page displays 5 records.

You can customize the assertion according to your specific requirement. If the count doesn't match, the assertion will throw an assertion error with the provided message.
