Depends Annotation
The @depends annotation helps you to define some dependencies between methods.
Format
1
2
3
/**
* @depends methodName
*/
Please note that dependencies don’t define the order in which the test methods are executed, so you still have to keep to proper order for your methods.
Example 1
Let’s check the following basic example.

/**
* @return int
*/
public function testOne(): int
{
$number = 2;
$this->assertEquals(2, $number);
return $number;
}
/**
* @depends testOne
*
* @param $number
*/
public function testNumber($number)
{
$this->assertEquals(2, $number);
}
Example 2
If using multiple dependencies, arguments are passed in the annotations’ defined order.

/**
* @return int
*/
public function testTwo(): int
{
$number = 2;
$this->assertEquals(2, $number);
return $number;
}
/**
* @return int
*/
public function testOne(): int
{
$number = 1;
$this->assertEquals(1, $number);
return $number;
}
/**
* @depends testOne
* @depends testTwo
*
* @param $one
* @param $two
*/
public function testNumber(int $one, int $two)
{
$this->assertEquals(1, $one);
$this->assertEquals(2, $two);
}
Example 3
Let’s check the following practical example, where we’ll be checking the customer email by customer ID.

public function testEmail(CustomerInterface $customer)
{
$this->assertEquals('customer@example.com', $customer->getEmail());
