To be able to run Selenium tests, you need to have webserver, database and Selenium running. Following environment variables configure where testsuite connects:

TESTSUITE_USER

Username to connect on the interface located at TESTSUITE_URL

TESTSUITE_PASSWORD

Password to connect on the interface located at TESTSUITE_URL

TESTSUITE_DATABASE_PREFIX

Database prefix to use for testing (Avoid database grouping characters like _).

TESTSUITE_URL

URL where tested phpMyAdmin is available.

Additionally you need to configure link to Selenium and browsers. You can either setup Selenium locally or use BrowserStack automated testing.

For local setup, define following:

TESTSUITE_SELENIUM_HOST

Host where Selenium is running.

TESTSUITE_SELENIUM_PORT

Port where to connect.

TESTSUITE_SELENIUM_BROWSER

Browser to use for testing inside Selenium.

With BrowserStack, set following:

TESTSUITE_BROWSERSTACK_USER

BrowserStack username.

TESTSUITE_BROWSERSTACK_KEY

BrowserStack access key.

For example you can use following setup in phpunit.xml:

<php>
    <env name="TESTSUITE_USER" value="root"/>
    <env name="TESTSUITE_PASSWORD" value="root"/>
    <env name="TESTSUITE_DATABASE_PREFIX" value="test"/>
    <env name="TESTSUITE_URL" value="http://localhost/phpmyadmin/" />
    <env name="TESTSUITE_SELENIUM_HOST" value="127.0.0.1" />
    <env name="TESTSUITE_SELENIUM_PORT" value="4444" />
</php>

We're using our selenium tests on the GitHub CI.

To run tests locally, you need to install BrowserStack tool to enable local testing, see their website for instructions:

https://www.browserstack.com/local-testing#command-line

Following instructions use PHP's built in server for the testing:

# Export BrowserStack credentials in the environment:
export TESTSUITE_BROWSERSTACK_USER=your_username
export TESTSUITE_BROWSERSTACK_KEY=your_key

# Port where tests will be running
export TESTSUITE_PORT=9000
export TESTSUITE_URL=http://127.0.0.1:$TESTSUITE_PORT/

# Start PHP built in server
php --server 127.0.0.1:$TESTSUITE_PORT > php.log &

# Start BrowserStack Local client to forward the traffic
~/browserstack/BrowserStackLocal -localIdentifier Manual "$TESTSUITE_BROWSERSTACK_KEY" 127.0.0.1,$TESTSUITE_PORT,0 &

# Stop BrowserStack Local
~/browserstack/BrowserStackLocal --daemon stop
