An easier way to use PHPUnit with CodeIgniter 3.x.
- You don't have to modify CodeIgniter core files at all.
- You can write controller tests easily.
- Nothing is untestable, maybe.
- Well documented.
- PHP 7.3 or later
- If you use Monkey Patching, you must use PHP-Parser 4.2 or later as a Composer dependency.
- CodeIgniter 3.x
- If you want to upgrade to CodeIgniter4, see #361.
- PHPUnit 9.3 or later
- If you want to use PHPUnit 9.2 or earlier, please use ci-phpunit-test 2.x.
- NetBeans
- Go to Project Properties > Testing > PHPUnit, check Use Custom Test Suite checkbox, and select
application/tests/_ci_phpunit_test/TestSuiteProvider.php
.
- Go to Project Properties > Testing > PHPUnit, check Use Custom Test Suite checkbox, and select

- Download latest
ci-phpunit-test
from https://github.com/kenjis/ci-phpunit-test/releases. - Unzip and copy
application/tests
folder into yourapplication
folder in CodeIgniter project.
That's it.
$ cd /path/to/codeigniter/
$ composer require kenjis/ci-phpunit-test:^3.0 --dev
And run install.php
:
$ php vendor/kenjis/ci-phpunit-test/install.php --from-composer
- The above command always overwrites existing files.
- You must run it at CodeIgniter project root folder.
- You can specify your
application
andpublic
folder with option arguments, if you use custom folder paths.
$ php vendor/kenjis/ci-phpunit-test/install.php -a <application_dir> -p <public_dir> -t <unittest_dir>
So the default would be:
$ php vendor/kenjis/ci-phpunit-test/install.php -a application -p public -t application/tests
- But some paths may be not correct, in that case, please fix them in tests/Bootstrap.php.
- Download latest
ci-phpunit-test
from https://github.com/kenjis/ci-phpunit-test/releases. - Unzip and replace
application/tests/_ci_phpunit_test
folder. - Read Change Log.
$ cd /path/to/codeigniter/
$ composer update kenjis/ci-phpunit-test
Read Change Log.
If you're upgrading from a previous version of ci-phpunit-test
that created
an application/test/_ci_phpunit_test
directory and now want to directly use
ci-phpunit-test
from Composer, you have a couple of additional steps:
- Delete the old test library directory:
$ rm -rf /path/to/codeigniter/application/tests/_ci_phpunit_test
- Edit the
application/tests/Bootstrap.php
file. At the bottom of the "set the main path constants" section, add the following:And replace any references todefine('CI_PHPUNIT_TESTPATH', implode( DIRECTORY_SEPARATOR, [dirname(APPPATH), 'vendor', 'kenjis', 'ci-phpunit-test', 'application', 'tests', '_ci_phpunit_test'] ).DIRECTORY_SEPARATOR);
__DIR__ . '/_ci_phpunit_test/
orTESTPATH . '_ci_phpunit_test
withCI_PHPUNIT_TESTPATH . '
. (So, for example,__DIR__ . '/_ci_phpunit_test/CIPHPUnitTest.php'
would becomeCI_PHPUNIT_TESTPATH . '/CIPHPUnitTest.php'
.)
You need to install PHPUnit before running tests.
If you use Composer:
$ composer require phpunit/phpunit --dev
$ cd /path/to/codeigniter/
$ vendor/bin/phpunit -c application/tests/
PHPUnit 9.5.4 by Sebastian Bergmann and contributors.
... 3 / 3 (100%)

To generate coverage report, Xdebug is needed.
If you want to run a single test case file:
$ vendor/bin/phpunit -c application/tests/ application/tests/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(): void
{
$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->assertStringContainsString(
'<title>Welcome to CodeIgniter</title>', $output
);
}
}
