The minimum requirement by this project template that your Web server supports PHP 5.4.0.
You can then install this project template using the following command:
php composer.phar create-project --prefer-dist --stability=dev yiisoft/yii2-app-basic basic
Now you should be able to access the application through the following URL, assuming
basic is the directory
directly under the Web root.
Extract the archive file downloaded from yiiframework.com to
a directory named
basic that is directly under the Web root.
Set cookie validation key in
config/web.php file to some random secret string:
'request' => [ // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation 'cookieValidationKey' => '<secret random string goes here>', ],
You can then access the application through the following URL:
Edit the file
config/db.php with real data, for example:
return [ 'class' => 'yii\db\Connection', 'dsn' => 'mysql:host=localhost;dbname=yii2basic', 'username' => 'root', 'password' => '1234', 'charset' => 'utf8', ];
config/directory to customize your application as required.
testsdirectory for information specific to basic application tests.
Tests are located in
tests directory. They are developed with Codeception PHP Testing Framework.
By default there are 3 test suites:
Tests can be executed by running
The command above will execute unit and functional tests. Unit tests are testing the system components, while functional tests are for testing user interaction. Acceptance tests are disabled by default as they require additional setup since they perform testing in real browser.
To execute acceptance tests do the following:
tests/acceptance.suite.yml to enable suite configuration
codeception/base package in
codeception/codeception to install full featured
version of Codeception
Update dependencies with Composer
Download Selenium Server and launch it:
java -jar ~/selenium-server-standalone-x.xx.x.jar
# for Firefox java -jar -Dwebdriver.gecko.driver=~/geckodriver ~/selenium-server-standalone-3.xx.x.jar # for Google Chrome java -jar -Dwebdriver.chrome.driver=~/chromedriver ~/selenium-server-standalone-3.xx.x.jar
As an alternative way you can use already configured Docker container with older versions of Selenium and Firefox:
docker run --net=host selenium/standalone-firefox:2.53.0
yii2_basic_tests database and update it by applying migrations if you have them.
The database configuration can be found at
Start web server:
Now you can run all available tests
# run all available tests vendor/bin/codecept run # run acceptance tests vendor/bin/codecept run acceptance # run only unit and functional tests vendor/bin/codecept run unit,functional
By default, code coverage is disabled in
codeception.yml configuration file, you should uncomment needed rows to be able
to collect code coverage. You can run your tests and collect coverage with the following command:
#collect coverage for all tests vendor/bin/codecept run -- --coverage-html --coverage-xml #collect coverage only for unit tests vendor/bin/codecept run unit -- --coverage-html --coverage-xml #collect coverage for unit and functional tests vendor/bin/codecept run functional,unit -- --coverage-html --coverage-xml
You can see code coverage output under the
