Today’s
goal
• Set
up
and
use
Selenium
IDE
• Record
UA
tests
• Convert
to
PHPUnit
• Run
con'nuously
• Mul'

DISCLAIMER
S E L E N I U M T E S T S A R E N OT A
REPLACEMENT FOR REGULAR UNIT
TESTING. THEY ONLY PROVIDE AN
ADDITIONAL SET OF TESTS FOCUSED
ON USER ACCEPTANCE AND USER
EXPERIENCE TESTING.

Func'onal
tes'ng
• Test
func'onal
requirements
-‐ e.g.
no
access
to
proﬁle
without
authen'ca'on
• Test
UI
elements
on
the
web
interface
-‐ e.g.
buTons,
form
elements,
AJAX
controls,
…

A
word
of
cau'on!

• UA
tests
only
test
generated
output
-‐ not
a
replacement
for
unit
tes'ng
• UA
tests
are
heavily
depending
on
DOM
-‐ changes
to
the
DOM
might
lead
to
failing

The
PHPUnit
TestCase
29
<?php
class Example extends PHPUnit_Extensions_SeleniumTestCase
{
protected function setUp()
{
$this->setBrowser("*chrome");
$this->setBrowserUrl("http://www.theialive.com/");
}
public function testMyTestCase()
{
$this->open("/");
$this->click("link=login");
$this->waitForPageToLoad("30000");
$this->type("id=email", "dragonbe+tek13@gmail.com");
$this->type("id=password", "test1234");
$this->click("id=signin");
$this->click("link=Test demo");
$this->assertEquals("Done", $this->getText("xpath=//th[5]"));
$this->click("link=[EDIT]");
$this->assertTrue($this->isElementPresent("id=done"));
$this->click("link=sign off");
}
}
?>

Change
class
name
30
<?php
class Example extends PHPUnit_Extensions_SeleniumTestCase
{
{
}
{
$this->open("/");
}
}
?>
class MarkTaskDoneTest extends PHPUnit_Extensions_SeleniumTestCase

The
PHPUnit
TestCase
31
<?php
{
{
}
{
$this->open("/");
}
}
?>
{
$this->setBrowser("*iexplore");
$this->setHost('192.168.56.101');
$this->setPort(12666);
}

Meaningful

<?php
{
{
$this->setBrowser("*iexplore");
$this->setHost('192.168.56.101');
$this->setPort(12666);
}
{
$this->open("/");
}
}
?>

startSeleniumStandAlone.BAT
33
"C:Program FilesJavajre7binjava.exe"
-jar "C:Jarselenium-server-standalone-2.28.0.jar"

Advantages
38
• You
can
start

immediately
• Even
test
“hard

kind
of
situa'ons
• More
nodes
for
parallel
tes'ng
• Tes'ng
diﬀerent

and
plaforms
• Con'nuous
Integra'on
possible

Modify
MarkTaskDoneTest

<?php
/**

*
* @group Selenium
*/
require_once 'TestCase.php';
class MarkTaskDoneTest extends TestCase
{
public function testMarkTestAsDone()
{
$this->open("/");
$this->type("id=email", TestCase::USERNAME);
$this->type("id=password", TestCase::PASSWORD);
}
}
45
Require the TestCase
and extend it

Benefits
• run
your
tests
on
mul'ple
browsers
• detect
flaws
in
specific
browsers
(e.g.
IE6)
-‐ adapt
your
apps
to
solve
these
flaws

The
GRID
50
• Procedure
-‐ centralized
server
(HUB)
-‐ commands
clients
(nodes)
registered
-‐ and
executes
the
tests
• Goal
-‐ allow
for
automa'on
-‐ adding
clients
as
you
go
