An easier way to use PHPUnit with CodeIgniter 3.0.
- You don't have to modify CodeIgniter core files at all.
- You can write controller tests easily.
- Nothing is untestable, maybe.
- Well documented.
- PHP 5.4.0 or later
- CodeIgniter 3.0.*
- PHPUnit 4.3 or later (4.7 or later is recommended)
- If you use NetBeans 8.0.2, please use 4.7. 4.8 is not compatible yet. You can download old version of
phpunit.pharfrom https://phar.phpunit.de/.
- If you use NetBeans 8.0.2, please use 4.7. 4.8 is not compatible yet. You can download old version of

- Go to Project Properties > Testing > PHPUnit, check Use Custom Test Suite checkbox, and select
application/tests/_ci_phpunit_test/TestSuiteProvider.php.

Download latest ci-phpunit-test: https://github.com/kenjis/ci-phpunit-test/releases
Unzip and copy application/tests folder into your application folder in CodeIgniter project. That's it.
If you like Composer:
$ cd /path/to/codeigniter/
$ composer require kenjis/ci-phpunit-test --dev
And run install.php:
$ php vendor/kenjis/ci-phpunit-test/install.php
- Above command always overwrites exisiting files.
- You must run it at CodeIgniter project root folder.
Download latest ci-phpunit-test: https://github.com/kenjis/ci-phpunit-test/releases
Unzip and replace application/tests/_ci_phpunit_test folder.
If you like Composer:
$ cd /path/to/codeigniter/
$ composer update kenjis/ci-phpunit-test
$ php vendor/kenjis/ci-phpunit-test/update.php
You have to install PHPUnit before running tests.
Note: You must run phpunit command in application/tests folder.
$ cd /path/to/codeigniter/
$ cd application/tests/
$ phpunit

To generate coverage report, Xdebug is needed.
If you want to run a single test case file:
$ phpunit models/Category_model_test.php
As an example, a test case class for Inventory_model would be as follows:
<?php
class Inventory_model_test extends TestCase
{
public function setUp()
{
$this->resetInstance();
$this->CI->load->model('Inventory_model');
$this->obj = $this->CI->Inventory_model;
}
public function test_get_category_list()
{
$expected = [
1 => 'Book',
2 => 'CD',
3 => 'DVD',
];
$list = $this->obj->get_category_list();
foreach ($list as $category) {
$this->assertEquals($expected[$category->id], $category->name);
}
}
public function test_get_category_name()
{
$actual = $this->obj->get_category_name(1);
$expected = 'Book';
$this->assertEquals($expected, $actual);
}
}As an example, a test case class for Welcome controller would be as follows:
<?php
class Welcome_test extends TestCase
{
public function test_index()
{
$output = $this->request('GET', 'welcome/index');
$this->assertContains(
'<title>Welcome to CodeIgniter</title>', $output
);
}
