Knowing to interpret the phpunit tests - yii

Question

I´m trying to configure the fixtures and phpunit system is returned the next message '.E', but I don´t know how interpret it:
C:\kyopol\Apache 2.22.22\htdocs\demo\protected\tests>phpunit unit/EntityTest.php
PHPUnit 3.7.14 by Sebastian Bergmann.
Configuration read from C:\kyopol\Apache
2.22.22\htdocs\demo\protected\tests\phpunit.xml
.E
Time: 2 seconds, Memory: 6.50Mb
There was 1 error:
1) EntityTest::testRead Undefined variable: newEntity
C:\kyopol\Apache
2.22.22\htdocs\demo\protected\tests\unit\EntityTest.php:37
FAILURES! Tests: 2, Assertions: 3, Errors: 1.
Next, class test EntityTest.php data code:
class EntityTest extends CDbTestCase
{
public function testCreate()
{
//CREATE a new Entity
$newEntity=new Entity;
$newEntity->setAttributes(
array(
'name' => 'Test Entity 1',
'description' => 'Test entity number one',
'type_id' => 1,
'location_lat' => 77,
'location_lon' => 77,
'create_time' => '2013-02-16 20:36:00',
'create_user_id' => 1,
'update_time' => '0000-00-00 00:00:00',
'update_user_id' => 0,
)
);
$this->assertTrue($newEntity->save(false));
//READ a Entity
$retrievedEntity=Entity::model()->findByPk($newEntity->id);
$this->assertTrue($retrievedEntity instanceof Entity);
$this->assertEquals('Test Entity 1',$retrievedEntity->name);
}
public function testRead()
{
//READ a Entity
$retrievedEntity=Entity::model()->findByPk($newEntity->id);
$this->assertTrue($retrievedEntity instanceof Entity);
$this->assertEquals('Test Entity 1',$retrievedEntity->name);
}
}
What is it meaning the capital letter 'E' and the previous point '.' ?
In general: Could nobody said me how knows to interpret output messages in phpunit?
Cheers.

Answer 1

One of your tests is failing so that's why you see the E. The other one is passing, indicated by a ..
If there are any error messages in the tests they will be summarized at the end.
The error message of your failing test is "Undefined variable: newEntity".
Your first line in testRead() is:
$retrievedEntity=Entity::model()->findByPk($newEntity->id);
But you have never setup $newEntity in that test.
