How to set specific class properties for a PHPunit test?

Question

What is a good best practice for phpunit to set some default configuration values in a test?

I'm thinking of values like

username

client id no.

so on..

Normally I would set this using the constructor or some setters but I'm not sure how to do this when I only have a class like this

class RestTest extends PHPUnit_Framework_TestCase {

For example I'm trying to make test cases for a REST and SOAP service.

I need to specify the url/user and pass but they change on dev/test/production so I need a clean way to specify them.

If you have some default values like a UserId that you need in every testcase of your test I'd suggest setting those in the setUp method of your class.

Just an example for setting the values:

class MtTest extends PHPUnit_Framework_TestCase {

    // As a property
    private $testUser = 7;

    // In the setUp
    public function setUp() {
        $this->testUser = 7;
        $this->defaultName = "BOB";
        $this->MtClass = new Mt();
    }

    public function testFoo() {
         $this->assertTrue($this->MtClass->userExists($this->testUser));
    }
}

If you have a set of values that you need to feed into one test method use DataProviders like @SilverLight (+1) suggested.

Response to comment:

If you need some kind of environment setup (for whatever you are trying to do, I'll just go with username for now since i can't guess) you could set those in your PHPUnit Bootstrap (or the file you pass to --bootstrap):

bootstrap.php

<?php
define("PHPUnit_Username", "Fuuu");
// or
$phpunitConfig = new Array(
     "username" => "fuu",
)
// or whatever suits you there. No reason for me to type a config object i guess
class MyPHPUnitConfig {
     public function getUsername() { return "wtf"; }
}

and maybe have your own base Testclass

<?php
class MyBaseTest extends PHPUnit_Framework_TestCase {

    public function setUp() {
        parent::setUp();
        $this->config = new MyPHPUnitConfig();
    }
}

and extend from that. Or use setUpBeforeClass to only do it once per test class.

If that doesn't answer your question i just don't get what you are ameing at. It's a testcase, it doesn't have any strong dependencies and it kinda shouldn't have any (Isolation) and i don't guess your problem is how to get a value into your setUp function is it? (Because thats kinda not a phpunit issue).

Let me know if that helped
