C. Test automated acceptance testing with Selenium
D. All of the above
E. None of the above

An assertion is…?
A. Verifying that an expected value matches the
result of a process?
B. Verifying that a process produces results
C. A transformation of a value

Assertion
• is a true/false statement
• to match an expectation
• with the result of functionality under test

Available assertions
• assertArrayHasKey()
• assertArraySubset()
• assertClassHasAttribute()
• assertClassHasStaticAttribute()
• assertContains()
• assertContainsOnly()
• assertContainsOnlyInstancesOf()
• assertCount()
• assertEmpty()
• assertEqualXMLStructure()
• assertEquals()
• assertFalse()
• assertFileEquals()
• assertFileExists()
• assertGreaterThan()
• assertGreaterThanOrEqual()
• assertInstanceOf()
• assertInternalType()
• assertJsonFileEqualsJsonFile()

• assertJsonStringEqualsJsonString()
• assertLessThan()
• assertLessThanOrEqual()
• assertNull()
• assertObjectHasAttribute()
• assertRegExp()
• assertStringMatchesFormat()
• assertStringMatchesFormatFile()
• assertSame()
• assertStringEndsWith()
• assertStringEqualsFile()
• assertStringStartsWith()
• assertThat()
• assertTrue()
• assertXmlFileEqualsXmlFile()
• assertXmlStringEqualsXmlFile()
• assertXmlStringEqualsXmlString()

Example usage
Assertions
// Asserting a value returned by $myClass->myMethod() is TRUE
$this->assertTrue($myClass->myMethod());
// Asserting that a string matches type and value of $myClass->toString()
$this->assertSame('my string', $myClass->toString());
// Asserting that the value matches $myClass-
>addOne(0), type check not necessary
$this->assertEquals('1', $myClass->addOne(0));
// Assserting that the result of $myClass->getBirthday()->format('Y')
// is greater than the expected value
$this->assertGreaterThan(1900, $myClass->getBirthday()->format('Y'));
// Asserting a value is NULL with a specified error message
$this->assertNull(
$myClass->getProperty(),
'When instantiating MyClass the property value should be NULL but is
' . $myClass->getProperty()
);

Exercise 0.0
• What will happen when you run PHPUnit now?
• Checkout branch ex-0.0
php composer.phar dump-autoload
• Run PHPUnit

Let’s write our ﬁrst test
<?php
namespace In2itTestWorkshopCtsr;
use In2itWorkshopCtsrSampleClass;
class SampleClassTest extends PHPUnit_Framework_TestCase
{
    public function testSomethingReturnsGreeting()
    {
        $sampleClass = new SampleClass();
        $this->assertSame(
            'Hello World!', $sampleClass->doSomething()
        );
    }
}

Exercise 0.1
• Run PHPUnit

Error?
Got Error?
error: Your local changes to the following files would be overwritten by checkout:
composer.lock
Please, commit your changes or stash them before you can switch branches.
Aborting
Solution
git checkout -- composer.lock

Write our class
<?php
namespace In2itWorkshopCtsr;
class SampleClass
{
    public function doSomething()
    {
        return 'Hello World!';
    }
}

Exercise 0.2
• Run PHPUnit

Exercise 0.3
• Test that you can provide an argument and the
argument will be returned as “Hello <arg>!”
• Write the test
• Modify the class

Modifying the test class
    public function testSomethingReturnsArgument()
    {
        $sampleClass = new SampleClass();
        $argument = 'Class';
        $this->assertSame(
            sprintf('Hello %s!', $argument),
            $sampleClass->doSomething($argument)
        );
    }

Modify the SampleClass
<?php
class SampleClass
{
    public function doSomething($argument)
    {
        return 'Hello ' . $argument . '!';
    }
}

Update further
<?php
class SampleClass
{
    public function doSomething($argument = 'World')
    {
        return 'Hello ' . $argument . '!';
    }
}

Functional requirements
• Application needs to manage cron entries, where
all scheduled tasks are stored in a database and
written to the crontab when saved.

What is crontab?
• A tool on UNIX-like systems to execute tasks at a certain interval
• Each line contains the following items:
• Minutes and/or interval
• Hours and/or interval
• Days of the month (DOM) and/or interval
• Months and/or interval
• Days of the week (DOW) and/or interval
• Executable command

Example crontab
# Minutes Hours DOM Months DOW Command
# Warm up caches with new products
# Every 5 minutes each day
*/5 * * * * /bin/sh /path/to/productCollector.sh 2>&1
# Send marketing mail to active customers
# Every Monday at 9:30am
30 9 * * 1 /usr/bin/php /path/to/marketingMailSender.php 2>&1
# Clean up waste
# Every day at 6am, 1pm and 5pm from Monday to Friday
0 6,13,17 * * 1-5 /bin/sh /path/to/wasteCleaner.sh 2>&1

Analysis
• crontab = collection of entries
• Each entry contains 5 assets and a command
• Each asset can contain a
• Wildcard (full range)
• Range n-m (subset of full range)
• List n,m,o
• A single value n
• With similar intervals (without the wildcard)

https://www.ﬂickr.com/photos/caveman_92223/3968354387

• cronmanager
• collection of crontab entries
• each entry contains
• minutes (collection) and interval (collection)
• hours (collection) and interval (collection)
• days of the month (collection) and interval (collection)
• months (collection) and interval (collection)
• days of the week (collection) and interval (collection)
• command string
• each entry collection (minutes, hours, dom, months, dow) requires a range
• minutes (0 - 59)
• hours (0 - 23)
• days of the month (1 - 31)
• month (1 - 12)
• days of the week (0 - 7) (0 & 7 are Sunday)
• crontab is write-only, so we need to update the full crontab completely

<?php
class CronManagerTest extends PHPUnit_Framework_TestCase
{
    public function testCronManagerCanAddAnEntry()
    {
        $entry = new stdClass();
        $cronman = new CronManager();
        $cronman->addEntry($entry);
        $this->assertCount(1, $cronman);
    }
}

<?php
class CronManager implements Countable, Iterator
{
    protected $stack;
    protected $pointer;
    protected $counter;
    public function addEntry($entry)
    {
        $this->stack[] = $entry;
        $this->counter++;
    }
    // Implement the Iterator and Countable methods here.
    // - Iterator: http://php.net/manual/en/class.iterator.php
    // - Countable: http://php.net/manual/en/class.countable.php
    public function current() {/**... */}
    public function next() {/**... */}
    public function key() {/**... */}
    public function valid() {/**... */}
    public function rewind() {/**... */}
    public function count() {/**... */}
}

<?php
use In2itWorkshopCtsrCronManager;
class CronManagerTest extends PHPUnit_Framework_TestCase
{
    public function testCronManagerCanAddAnEntry()
    {
        $entry = new stdClass();
        $cronman = new CronManager();
        $cronman->addEntry($entry);
        $this->assertCount(1, $cronman);
    }
}

Exercise 1.0
• Create a test for the Entry class

Something like this…
<?php
use In2itWorkshopCtsrCronManagerEntry;
class EntryTest extends PHPUnit_Framework_TestCase
{
public function testEntryContainsAllFields() { /** ... */ }
public function testEntryCanSetEntryElements() { /** ... */ }
}

Something like this… (2)
public function testEntryContainsAllFields()
{
    $entry = new Entry();
    $this->assertCount(0, $entry->getMinutes());
    $this->assertCount(0, $entry->getHours());
    $this->assertCount(0, $entry->getDom());
    $this->assertCount(0, $entry->getMonths());
    $this->assertCount(0, $entry->getDow());
    $this->assertSame('', $entry->getCommand());
}

Something like this… (3)
public function testEntryCanSetEntryElements()
{
    $assetCollection = $this->getMock(
        'In2itWorkshopCtsrCronManagerAssetCollection'
    );
    $entry = new Entry();
    $entry->setMinutes($assetCollection);
    $this->assertInstanceOf(
        'In2itWorkshopCtsrCronManagerAssetCollection',
        $entry->getMinutes()
    );
    /*
     * Similar routines for Hours, Days of the Month, Months and Days of the week
     */
    $command = $this->getMock('In2itWorkshopCtsrCronManagerCommand');
    $entry->setCommand($command);
    $this->assertInstanceOf(
        'In2itWorkshopCtsrCronManagerCommand',
        $entry->getCommand()
    );
}

Exercise 1.1
• Have a look at all the tests

Pop-quiz
// Why are we using Mock objects to test functionality?
$assetCollection = $this->getMock(
    'In2itWorkshopCtsrCronManagerAssetCollection'
);
$asset = $this->getMock(
    'In2itWorkshopCtsrCronManagerAsset'
);
$entry = $this->getMock(
    'In2itWorkshopCtsrCronManagerEntry'
);

Question
• Are we protected against bad input?
• Yes
• No

Create some bad data
public function badDataProvider()
{
    return array (
        array ('foo'),
        array (new stdClass()),
        array (array ()),
        array (1.50),
    );
}

And let’s test it!
/**
* @dataProvider badDataProvider
* @covers In2itWorkshopCtsrCronManagerAsset::__construct
* @covers In2itWorkshopCtsrCronManagerAsset::setValue
* @covers In2itWorkshopCtsrCronManagerAsset::getValue
* @expectedException InvalidArgumentException
*/
public function testRejectBadData($badData)
{
$asset = new Asset($badData);
$this->fail('Expected InvalidArgumentException to be thrown');
}

Let’s ﬁx that!
/**
* @param int $value
* @throws InvalidArgumentException
*/
public function setValue($value)
{
    if (!is_int($value)) {
        throw new InvalidArgumentException(
            'You've provided an invalid argument'
        );
    }
    if (false === ($result = filter_var($value, FILTER_VALIDATE_INT))) {
        throw new InvalidArgumentException(
            'You've provided an invalid argument'
        );
    }
    $this->value = (int) $value;
}

House of Reﬂection

Let’s do this…
<?php
require_once 'include.php';
class DependencyTest extends PHPUnit_Framework_TestCase
{
    public function testConstructorSetsProperSettings()
    {
        require_once 'include/module_dependency.php';
        // We have a problem, the constructor is private!
    }
}

Let’s use the static
$params = array (
    'moduleName' => 'Foo_Bar',
    'minVersion' => 0,
    'maxVersion' => 1,
    'maxOk' => true,
);
// We use a static method for this test
$dependency = Dependency::requires_range(
    $params['moduleName'],
    $params['minVersion'],
    $params['maxVersion'],
    $params['maxOk']
);
// We use reflection to see if properties are set correctly
$reflectionClass = new ReflectionClass('Dependency');

Use the reﬂection to assert
// Let's retrieve the private properties
$moduleName = $reflectionClass->getProperty('module_name');
$moduleName->setAccessible(true);
$minVersion = $reflectionClass->getProperty('version_min');
$minVersion->setAccessible(true);
$maxVersion = $reflectionClass->getProperty('version_max');
$maxVersion->setAccessible(true);
$maxOk = $reflectionClass->getProperty('compare_max');
$maxOk->setAccessible(true);
// Let's assert
$this->assertEquals($params['moduleName'], $moduleName->getValue($dependency),
    'Expected value does not match the value set’);
$this->assertEquals($params['minVersion'], $minVersion->getValue($dependency),
$this->assertEquals($params['maxVersion'], $maxVersion->getValue($dependency),
$this->assertEquals('<=', $maxOk->getValue($dependency),
    'Expected value does not match the value set');
