如何使用WebDriver和Java在日历表中找到链接？

Question

I'm learning to work with Maven, Java, testng and webdriver by doing a self training course. I been doing great with all exercises until I got to the last one, I honestly don't know how to solve it. Let me give you some context:

Exercise description : Open the site homepage and using the calendar(html calendar in a wordpress site), check how many days of the current month contain posts, then access the first day which has post and print the titles of the posts in the console.

When any day in the calendar has posts, instead of showing the day in plain text, the site shows the day number as a link that once clicked opens the lists of posts in the main page.

This is a screen capture of how this site looks when I click on the day which has posts, in this case October 10th 2013: http://i.stack.imgur.com/wGRO2.jpg

Like I said the site is a wordpress site (unfortunately can only be accessed through VPN so I can't share it), and I need to use the calendar widget which is a table. I was able to go over each row and column of the table and print each column's text.

But how do I find if any of those days have a link in it and then having located that element how can I access it and print it's content (is this case they want me to print the titles of all posts created under that date)?

This is the code I'm using to go over the entire table and print the content:

//Test Case 6
    @Test (timeOut=20000)
    public void TestCalendar(){
        HomePage homePage = PageFactory.initElements(driver, HomePage.class);
        homePage.Go(driver);
        WebElement table = homePage.ReturnCalendarElement();
        //Actual Month has no posts, so we select previous one which has 2 posts
        homePage.ClickPreviousMonth();
        //We Get All rows of the calendar then we get all columns and its data
        List<WebElement> rows = table.findElements(By.tagName("tr"));
        for (WebElement row: rows) {
            List<WebElement> cols= row.findElements(By.tagName("td"));
            for (WebElement col: cols){
                System.out.print(col.getText() + "\t");

            }
        }
    }

I'm adding the HTML code of that page in case it helps you to provide some answers:

Follow this link to open a Public Gist with the HTML code of the page: https://gist.github.com/anonymous/599cd722b5c906808528

The following is the HTML code for the Table I'm testing:

<aside id="calendar-2" class="widget widget_calendar"><h3 class="widget-title">Posts by date:</h3><div id="calendar_wrap"><table id="wp-calendar">
<caption>October 2013</caption>
<thead>
<tr>
    <th scope="col" title="Monday">M</th>
    <th scope="col" title="Tuesday">T</th>
    <th scope="col" title="Wednesday">W</th>
    <th scope="col" title="Thursday">T</th>
    <th scope="col" title="Friday">F</th>
    <th scope="col" title="Saturday">S</th>
    <th scope="col" title="Sunday">S</th>
</tr>
</thead>

<tfoot>
<tr>
    <td colspan="3" id="prev" class="pad">&nbsp;</td>
    <td class="pad">&nbsp;</td>
    <td colspan="3" id="next" class="pad">&nbsp;</td>
</tr>
</tfoot>

<tbody>
<tr>
    <td colspan="1" class="pad">&nbsp;</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
</tr>
<tr>
    <td>7</td>
    <td>8</td>
    <td>9</td>
    <td><a href="http://10.28.148.127/wordpress/2013/10/10/" title="What software testing is, It is used for:">10</a></td>
    <td>11</td>
    <td>12</td>
    <td>13</td>
</tr>
<tr>
    <td>14</td>
    <td>15</td>
    <td>16</td>
    <td>17</td>
    <td>18</td>
    <td>19</td>
    <td>20</td>
</tr>
<tr>
    <td>21</td>
    <td>22</td>
    <td>23</td>
    <td>24</td>
    <td>25</td>
    <td>26</td>
    <td>27</td>
</tr>
<tr>
    <td>28</td>
    <td>29</td>
    <td>30</td>
    <td>31</td>
    <td class="pad" colspan="3">&nbsp;</td>
</tr>
</tbody>
</table></div></aside>

This is the last problem I need to solve to end with this training, so any help and orientation will be highly appreciated.

Answer 1

Use a better CSS query to get the links of the calendar.

It would be something like:

td a

Elements TD with a link A inside.

Not much help without the HTML code of the page.

Answer 2

I ended up finding a solution, while i'm sure there should be a better way to do this. But this worked for me & might help someone else somehow:

// Test Case 6
@Test(timeOut = 40000)
public void TestCalendar() {
    HomePage homePage = PageFactory.initElements(driver, HomePage.class);
    CalendarPage calendarPage = PageFactory.initElements(driver,
            CalendarPage.class);
    homePage.Go(driver); //this just navigates to the page
    homePage.ReturnPreviousMonth().click(); 
    //returns the calendar element mapped in the page
    WebElement table = homePage.ReturnCalendarElement();
    WebElement dayWithPost = calendarPage.GetFirstDayWithPosts(driver,
            table);
    Assert.assertNotNull(dayWithPost);
    System.out.println("We'll be working with the following day: " + dayWithPost.getText());
    dayWithPost.click();
    List<WebElement> articles = driver.findElements(By
            .className("entry-title"));
    for (WebElement article : articles) {
        System.out.println("Retrieved Post's Title: [ "
                + article.findElement(By.tagName("a")).getText() + " ]");

    }



public class CalendarPage {

public List<WebElement> ReturnArticlesOnPage(WebDriver driver) {
    List<WebElement> articles = driver.findElements(By.tagName("article"));
    return articles;
}

public WebElement GetFirstDayWithPosts(WebDriver driver, WebElement table) {

    List<WebElement> rows = table.findElements(By.tagName("tr"));
    for (WebElement row : rows) {
        List<WebElement> cols = row.findElements(By.tagName("td"));
        for (WebElement col : cols) {
            try {
                if (col.findElement(By.tagName("a")).getAttribute("href") != null ){
                    System.out.println("Day: " + col.getText()+ " has posts and was returned.");
                    return col;
                }

            }
            catch (NoSuchElementException e){
                //System.out.println("Day: " + col.getText()+ " has no posts.");
            }
        }

    }
    return null;
}

}
