In the modern web application development process, functional testing is an important aspect to ensure application quality. Codeception is a popular PHP testing framework that provides a simple API and easy-to-understand syntax to help us write efficient web functional tests. This article will introduce how to use Codeception for functional testing.
1. Install Codeception
First, we need to install Codeception. Codeception supports several ways to install, including Composer, phar package and manual download. Here we use Composer to install and execute the following command:
composer require codeception/codeception --dev
After the installation is completed, we can generate the codeception.yml
configuration file in the project root directory:
./vendor/bin/codecept bootstrap
2. Write test cases
The test cases in Codeception are divided into different levels, including unit tests, integration tests and functional tests. In this article, we focus on functional testing.
Use the following command to create a test suite named FunctionalTests
:
./vendor/bin/codecept generate:suite functional
In the test case directory, a FunctionalTests# containing test cases will be automatically generated. ##folder.
http://example.com:
./vendor/bin/codecept generate:cept functional ExampleTestIn the generated test case file, we can use
$I->amOnPage method to access the web page:
<?php $I = new FunctionalTester($scenario); $I->amOnPage('http://example.com'); $I->see('Hello, world!');In this test case, we use the
$I->amOnPage method to open the web page. Then, we use the
$I->see method to check whether the text
Hello, world! exists in the web page.
<?php $I = new FunctionalTester($scenario); $I->amOnPage('http://example.com'); $I->fillField('username', 'testuser'); $I->click('Submit'); $I->see('Welcome, testuser!');In this test case, we use the
$I->fillField method to fill in the
username form field. Then, we use the
$I->click method to simulate the user clicking the
Submit button. Finally, we use the
$I->see method to check whether the text
Welcome, testuser! exists in the web page.
$I->haveInDatabase method to add data to the database and the
$I->seeInDatabase method to check whether the data exists.
<?php $I = new FunctionalTester($scenario); $I->amOnPage('http://example.com/create-user.php'); $I->fillField('username', 'testuser'); $I->fillField('password', 'testpassword'); $I->click('Submit'); $I->seeInDatabase('users', ['username' => 'testuser']);In this test case, we use the
$I->haveInDatabase method A record is added to the
users table. We then use the
$I->seeInDatabase method to check whether there is a record with the
username field being
testuser.
./vendor/bin/codecept runIf we only want to run the
FunctionalTests test suite, we can use the following command:
./vendor/bin/codecept run functional4. SummaryUsing Codeception for functional testing can help us ensure the quality of the application. In this article, we learned how to write test cases and execute them. Codeception provides a simple API and easy-to-understand syntax, which can help us quickly write efficient web functional tests.
