Test Framework

The Test Framework resides within the not_for_release/testFramework directory. This directory is only really available if you checkout the Zen Cart code using git. It is not available if you just download the Zen Cart code via a release link.

Running Zen Cart tests locally has the potential to override your Zen Cart database and destroy data.

Preparation / Initial Setup

To prepare to run the Unit Test test suite:

1. First, install Composer:

• go to getcomposer.org
• download and install
• follow the Getting Started instructions.

2. Run composer install

3. Add vendor/bin to your path.

Unit Tests

Unit tests can be run using

composer tests

in the root directory of your Zen Cart install.

Currently, there are no local configuration requirements needed to run unit tests.

Database Integration Tests

Examples of integration tests with a test database are located in not_for_release/testFramework/Browser/Dbunit.

Database Fixtures

For each database table you need, you must first create a DatabaseFixture class under not_for_release/testFramework/Support/DatabaseFixtures. The class must implement:

1. A createTable() method with the CREATE TABLE sql
2. A seeder() method with the INSERT INTO sql

See the already present fixtures for the admin and the configuration_group tables as reference.

At the beginning of the tests the tables will be populated with the seed data, and then truncated at the end of the tests (using Laravel Capsule).

Configuration file

Create a configuration file under not_for_release/testFramework/Support/DatabaseConfigure using runner.configure.dusk.php as template. The file must be named <user>.configure.dusk.php, where <user> is replaced by the user that your php scripts run as (usually equal to $_SERVER['USER']). The file must contain the test database information (address, user, password, etc.)

Test case

The class not_for_release/testFramework/Browser/Dbunit/DatabaseTest.php is an example of how the test case should be structured:

use App\Models\Admin;
use Tests\Support\Traits\DatabaseConcerns;
use Tests\Support\zcUnitTestCase;

class DatabaseTest extends zcUnitTestCase
{
    use DatabaseConcerns;

    public $databaseFixtures = ['adminEmpty' => ['admin'], 'configurationGroup' => ['configuration_group']];

    public function testExample()
    {
        $f = Admin::all();
        $this->assertTrue(!count($f));
        $f = $this->db->Execute('SELECT * FROM ' . TABLE_ADMIN);
        $this->assertTrue(!$f->count());
    }
}

The trait DatabaseConcerns takes care of setting up the test database. $databaseFixtures is the list of Database Fixtures used by the tests.

You can also optionally use the Eloquent syntax by importing the database models first, located under laravel/App/Models.

Run the test case with phpunit like so:

phpunit --verbose --testsuite <TestSuite> --printer 'Sempro\PHPUnitPrettyPrinter\PrettyPrinterForPhpUnit9'

In the example above, <TestSuite> is Dbunit.

Browser Tests

NOTE: these tests have been temporarily removed from the repo, so the instructions below are no more valid right now. They are still a useful reference, and you can find the files in the repo history on github.

Automated browser tests can be run using

composer dusk

in the root directory of your Zen Cart install.

There are configuration requirements needed to run browser tests on your local machine.

Browser Test Configuration

If you want to run browser tests on your local machine, you will need to create 3 configuration files.

<user> is replaced by the user that your php scripts run as. You can find this by echoing $_SERVER['USER'] in some php script.

1. In not_for_release/testFramework/Browser/duskConfigures you will need to create a file called <user>.configure.dusk.php. An example file dusk.configure.php can be used as a template. Note: The database user TESTING_DB_SERVER_USERNAME must have sufficient rights to create a database.

2. not_for_release/testFramework/Browser/zencartConfigures/admin.<user>.configure.php

3. not_for_release/testFramework/Browser/zencartConfigures/catalog.<user>.configure.php

Files 2. and 3. should be copies of the normal configure.php files that you would have in admin/includes/configure.php and includes/configure.php.

Admin Alert Page

Normally, if the zc_install directory exists Zen Cart will display an alert page on any attempt to access admin URI’s. FIXME

Database Regeneration

When Browser tests are run, and in order to create some isolation between various tests the framework will dump whatever database you have set in the configuration files mentioned earlier.

It will then load the default database schema from zc_install/sql/install/mysql_zencart.sql and the demo data from zc_install/sql/demo/mysql_demo.sql

This means that if your testing database contains any changes from the default install, they will be lost.

If your need to keep your local changes then you must ensure that they have been added to zc_install/sql/install/mysql_zencart.sql and zc_install/sql/demo/mysql_demo.sql before running the browser tests.
