What is the order in which PHPUnit tests are run?

Question

Unit testing

The PHPUnit class has a test dependency.

public function test1(){
...
}

/**
* @depends test1
*/
public function test2(){
...
}

/**
* @depends test1
*/
public function test3(){
...
}

When a test is run, it is executed in the following sequence: test3, test1, test2. Because test3 depends on test1 (and it's not executed yet) - test3 is skipped.
I don’t understand why such an execution sequence and how to set it?

Answer 1

In general, tests should be independent.
Is there any way to change the code to avoid this problem?
