In any software
test automation, we may often run in to some challenges w.r.t usage of the
automation tool or the support it does provide for the Application under test (AUT).
We have listed some
of the challenges we generally face in the automation phase.
1. Handling multiple browser windows
Handling
the multiple browser windows is always been a challenge. This includes:
New popup window for date selection in the application.
New popup window for date selection in the application.
Here is the sample code to handle the date
popup
// Tp open calender
webdriver.findElement(By.xpath("//img[@alt='calendar']")).click();
Store the main window in a variable
String mainwindow = webdriver.getWindowHandle();
//switch from main/parent window to new
window using the windowhandles
for
(String newwindow : webdriver.getWindowHandles())
{
webdriver.switchTo().window(newwindow);
// perform action on new calendar window
opened webdriver.findElement(By.id("calendar_month_txt")).click();
}
Again, we need to switch back to main window
which has been initially opened to continue the test steps execution.
We will be using the SwitchTo command to
again select the main application window.
webdriver.switchTo().window(mainwindow);
Every
link clicked on the application will open a new window with dynamic title.
To switch between the window having the dynamic title
a.
Having
the date and time stamp in the title
Eg: “Test Application 2014-05-07
04:05PM”
b.
Having
the version number of the application release
Eg: “Test Application Ver: 14.02
release”
In order to work with these we need to use the regular expression to
switch between the windows by using the title names
Eg: assuming some part of the title is constant, then
webdriver.switchTo().window("Test Application *");
& if there is any random string before and after the required title
webdriver.switchTo().window(".*Test Application.*");
Now a days,
Requirements are very rich in nature where the developer are expected to handle
the every functionality in one single page with different frames in place.
Iframe
is used to embed the one document with in the other html document by which one
can handle new document or DOM with in the main webpage.
But
it will be obvious challenge to handle the different frames and switching
between them. And often the frames will be given under the
<frameset> </frameset>
Sample frames structure 1:
<frameset>
<iframe id=”frm1”>
<body>
<input
id=”txt1” type=”text”>FirstName</input>
</body>
</iframe>
<iframe id=” frm2”>
<body>
<input
id=”txt2” type=”text”>LastName</input>
</body>
</iframe>
</frameset>
In
the above case,
1.
Switch
to frame1
a.
webdriver.switchTo().frame("frm1");
2.
Perform
the action on the input box
a.
Webdriver.findElement(By.Id(“txt1”)).sendKeys(“user
name”);
3.
Then
switch back to the main content using the method called “defaultContent”
a.
webdriver.switchTo.
defaultContent();
4.
Again
switch to another frame2 to interact with other textbox
a.
webdriver.switchTo().frame("frm2");
b.
Webdriver.findElement(By.Id(“txt2”)).sendKeys(“password”);
Sample 2:
<frameset>
<iframe id=”frame1”>
<body>
<input
id=”txt1” type=”text”>FirstName</input>
</body>
<iframe id=”
frame2”>
<body>
<input
id=”txt2” type=”text”>LastName</input>
</body>
</iframe>
</iframe>
</frameset>
1.
Switch
to frame1
a.
webdriver.switchTo().frame("frm1");
2.
Perform
the action on the input box
a.
Webdriver.findElement(By.Id(“txt1”)).sendKeys(“user
name”);
3.
Again
switch to another frame2 to interact with other textbox
a.
webdriver.switchTo().frame("frm2");
b.
Webdriver.findElement(By.Id(“txt2”)).sendKeys(“password”);
4.
Then
switch back to the main content using the method called “defaultContent”
a.
webdriver.switchTo.
defaultContent();
3. Interacting
with the hidden elements in a webpage
Like
we see some of the applications are the webelements overlapped on top of the
actual elements like text box, combox box etc. Refer the image below.
We have the combo
box with Yes/No values, but actually “select” html tag is hidden and added a
span over it with anchor <a> tag to select the items in it.
Using Webdriver, we
are having the challenge to invoke the elements which are hidden. To handle
such elements we need to rely on java script executor as shown below.
String javascript = "
javascript:var s = document.getElementById('testobject');"
+ ln + "for (i = 0; i<
s.options.length; i++){"
+ ln + " if
(s.options[i].text.trim().toUpperCase() == '"+valuetomatch+"')
{"
+
ln + " s.options[i].selected = true;"
+
ln + " s.click();"
+
ln + " if (s.onchange) {"
+
ln + " s.onchange();"
+ ln + " }"
+
ln + " break;"
+
ln + " }"
+ ln + "}"; ((JavascriptExecutor)
webdriver).executeScript(javascript);
To click on any
hidden element
String Script =
"javascript:document.getElementById('testobject').click();";
((JavascriptExecutor)
webdriver).executeScript(Script);Here the java script command is formed as a string and being executed by the javascriptExecutor. As every browser we use has in built capability of executing the java script commands.
