Hi,

I've been reading into testing my PHP code particularly unit testing using PHPUnit. The problem I have is that most of my code is procedural with not even many functions. I have read that unit testing is more suitable for OO PHP however i have seen that many people say it can be used to test procedural. However, the examples i have seen of this have not been with code similar to mine.

I was wondering if anyone could demonstrate with some of my code how i would unit test parts of it. I have included my file that validates login details below if someone could help?

`<?php
session_start();
include'db_config.inc';

$error_flag = false;
$_SESSION['L_ERR_MSG'] = '';

try {
    $dbh = new PDO("mysql:host=127.0.0.1;dbname=$db", $user, $password);
}
catch (PDOException $e) {
    die($e->getMessage());
}

try {
$username = filter_var($_POST['username'], FILTER_SANITIZE_STRING, FILTER_FLAG_NO_ENCODE_QUOTES);
$password = filter_var($_POST['password'], FILTER_SANITIZE_STRING, FILTER_FLAG_NO_ENCODE_QUOTES);
}
catch(Exception $e) {
$_SESSION['L_ERR_MSG'] = $e;
    session_write_close();
    header("location: login_failed.php");
}

$_SESSION['username'] = $username;

if(!isset($username) or empty($username)){
if(!isset($password) or empty($password)){
    $_SESSION['L_ERR_MSG'] = 'Username and Password fields are empty. Please enter your details in them!';
    $error_flag = true;
}
else {
    $_SESSION['L_ERR_MSG'] = 'Username field is empty. Please enter your Username!';
    $error_flag = true;
}
}
else if(!isset($password) or empty($password)){
$_SESSION['L_ERR_MSG'] = 'Password field is empty. Please enter your Password!';
    $error_flag = true;
}

$password = encrypt_password($password);
$loginmatches = $dbh->query ("SELECT * FROM Member WHERE username = '$username'
                              AND password = '$password'");

if($error_flag){
    session_write_close();
header("location: login_failed.php");
exit();
}
else {
if($loginmatches){
    if($loginmatches->rowCount() == 1){
    $member = $loginmatches->fetch(PDO::FETCH_ASSOC);

    $dbh->exec ("INSERT INTO `Login` 
            (`username`,`loginTime`)
            VALUES ('$username',NOW())");

    $_SESSION['SESS_USER'] = $member['username'];
    $_SESSION['SESS_USER_SITEROLE'] = $member['siteRole'];

    if($_SESSION['REDIR_BOOKING'] == 1){
        header("location: book_taxi.php");
    }
    else {
        switch($member['siteRole']){
        case "MEMBER":
            header("location: member_profile.php");
            break;
        case "DRIVER":
            header("location: driver_profile.php");
            break;
        case "ADMIN":
            header("location: admin_profile.php");
            break;
        case "SUPERADMIN":
            header("location: superadmin_profile.php");
            break;
    }
    }
    }
else {
    $_SESSION['L_ERR_MSG'] = 'Incorrect Username and/or Password entered. Please try again!';
    session_write_close();
    header("location: login_failed.php");
}
}
}    

?>`

It would be good if i could test the different session messages etc.

Any help would be much appreciated.

I know about simpletest and phpunit tests already. Just don't know how it could be applied to my procedural code like i stated in my first post. I need to see an example regarding my code to know how i can apply it to the rest.

Just thought i'd give you guys a heads up.

I've been using Selenium which is an add on for firefox in which you can write tests for any website. So far i fully recommend.

Also, i know from this experience to write more in OO PHP from now on. Guess you have to make the mistakes as a beginner!
