Overview of this book

Web technologies are becoming increasingly complex and there is a need to test your web applications against a vast number of browsers and platforms, so you need to build highly reliable and maintainable test automation. This book will help you test your web applications effectively and efficiently with Selenium WebDriver."Selenium Testing Tools Cookbook" is an incremental guide that will help you learn and use advanced features of Selenium WebDriver API in various situations for building reliable test automation. You will learn how to effectively use features of Selenium using simple and detailed examples. This book will also teach you best practices, design patterns, and how to extend Selenium."Selenium Testing Tools Cookbook" shows developers and testers who already use Selenium, how to go to the next step and build a highly maintainable and reliable test framework using advanced features of the tool.The book starts with tips on advanced location strategy and effective use of Selenium WebDriver API. Then it demonstrates the use of design patterns such as Data Driven Tests and PageFactory for building maintainable test automation. It also explains extending Selenium WebDriver API along with implementing custom tasks and setting up your own distributed environment to run tests in parallel.It concludes with tips on integrating Selenium WebDriver with other popular tools, testing mobile web applications, and capturing videos of test runs. This books provides examples in Java, C#, Ruby, and Python."Selenium Testing Tools Cookbook" will help you in building a highly robust and maintainable test automation framework from start to finish.

Locating table rows and cells


While working with tables, we can locate the rows and cells effectively by using a set of the By class methods.

In this recipe, we will see how to locate rows and columns in table.

How to do it...

Let's create a simple test that will print data from a table, locating its rows and columns as follows:

@Test
public void testTable() { 
    
    WebElement simpleTable = driver.findElement(By.id("items"));
    
    //Get all rows
    List<WebElement> rows = simpleTable.findElements(By.tagName("tr"));
    assertEquals(3, rows.size());
    
    //Print data from each row
    for (WebElement row : rows) {
        List<WebElement> cols = row.findElements(By.tagName("td"));
        for (WebElement col : cols) {
            System.out.print(col.getText() + "\t");
        }
        System.out.println();
    }
}

How it works...

A table in HTML is a collection of <tr> and <td> elements for rows and cells, respectively. In the sample test, the table can be located as a WebElement using its ID as follows:

WebElement simpleTable = driver.findElement(By.id("items"));

To get all the rows from a table, the findElements() method is called on simpleTable and the tagName strategy is used to get all <tr> elements. These are rows of a table.

List<WebElement> rows = simpleTable.findElements(By.tagName("tr"));

Each <tr> element then holds the <td> elements, which are the columns or cells of the table. The test iterates through the row and columns to print the data in the following way:

//Print data from each row
for (WebElement row : rows) {
    List<WebElement> cols = row.findElements(By.tagName("td"));
    for (WebElement col : cols) {
        System.out.print(col.getText() + "\t");
    }
    System.out.println();
}

This method comes in handy when you have a test that needs to verify data in a table.

There's more…

We can also use CSS selectors or XPath for locating table rows and cells using index matching. In the following example, CSS selector is used to locate the first cell of the second row in the table:

WebElement cell = driver.findElement(By.cssSelector("table#items tbody tr:nth-child(2) td"));

Similarly using XPath, it can be done in the following way:

WebElement cell = driver.findElement(By.xpath("//table[@id='items']/tbody/tr[2]/td"));
