Cypress tests

The testing of the NPM module joomla-cypress is implemented using Cypress as well. Each Cypress custom command is executed at least once and the result is checked.

Running the tests

Requirements:

  • PHP (a Joomla-supported version)
  • Composer
  • NPM
  • Cypress
  • Web Server
  • Joomla sources
  • A database and PHP extensions for the database

Ensure Firefox is installed system-wide (check with npx cypress info).

For Joomla sources the following commands are sufficient:

git clone https://github.com/joomla/joomla-cms --depth 1
cd joomla-cms
composer install
npm ci

No additional configuration for Joomla is necessary, as the parameters are defined in the joomla-cypress/tests/cypress.config.mjs Cypress configuration file. A Joomla installation is not required if you start by running the entire test suite or the tests/e2e/joomla.cy.js test spec.

Note

The custom command installJoomlaMultilingualSite deletes the Joomla installation folder. You have to restore the installation folder after each test run, from saved copy or from GitHub and with recreating the installation/template/css folder:

git checkout installation
npm ci

Installation

Install the JavaScript dependencies:

git clone https://github.com/joomla-projects/joomla-cypress
cd joomla-cypress
npm ci

Configuration

Create the Cypress configuration file from the distribution template:

cp tests/cypress.config.dist.mjs tests/cypress.config.mjs

Adapt the environment variables in the file cypress.config.mjs, they should point to the site, user data and database environment. Most configurations are the same as with Joomla System Tests cypress.config.mjs file. Additional variables are

  • installationPath contains the file system path to your Joomla installation (used to delete the configuration.php file before installing Joomla)
  • instance specifies the Joomla major and minor version number, e.g. 53 for Joomla 5.3.

Tests

Running all tests headless:

npm test

Running the test suite without the installLanguage and installJoomlaMultilingualSite tests, if the language package is not yet available, on Windows PowerShell:

$env:CYPRESS_SKIP_INSTALL_LANGUAGES=1
npm test

Running only user.cy.js test spec file:

npx cypress run --spec tests/e2e/user.cy.js --config-file tests/cypress.config.mjs

Running tests with local Cypress GUI:

npm run open

Running the tests using JBT

JBT has integrated the testing of the NPM module joomla-cypress. In the installation/joomla-cypress directory the latest main branch version is already installed. Furthermore Joomla, databases, Cypress and sample module are already provided with JBT. Restoring the installation folder, running npm ci and handing over the sample module for installation are covered for you. This is implemented in the scripts tests, cypress and patch.

Patch installation/joomla-cypress e.g. with pull request #37 Fixing installJoomlaMultilingualSite():

scripts/patch installation joomla-cypress-37

Running the test suite headless for Joomla 5.2:

scripts/test 52 joomla-cypress

Cypress test run

Running only user.cy.js test spec file and watching the progress with NoVNC:

scripts/test 52 joomla-cypress tests/e2e/user.cy.js novnc

Cypress test user.cy.js file

Running the test suite for Joomla 5.3 and 6.0 without the installLanguage and installJoomlaMultilingualSite tests, if the language package is not yet available, on Unix-based systems:

CYPRESS_SKIP_INSTALL_LANGUAGES=1 scripts/test 53 60 joomla-cypress

Running tests with local Cypress GUI, e.g. on macOS or Linux:

scripts/cypress 52 joomla-cypress local

Running on Joomla 6.0 without the tests they install languages, with the Cypress GUI, e.g. on Windows 11 WSL2 Ubuntu:

CYPRESS_SKIP_INSTALL_LANGUAGES=1 scripts/cypress 60 joomla-cypress

Troubleshooting

  1. Ensure that you have installed the version of joomla-cypress to be tested and patched if necessary.
  2. If one test step fails, the target Joomla installation may reach a state causes subsequent tests to fail. Dependecies include deleting Joomla installation folder, deleting the configuration.php file, cancelling guided tours and disabling Joomla statistics. In such cases open the target Joomla installation administration to investigate or reinstall the target Joomla sources.
  3. For failed tests you can inspect the screenshots in tests/screenshots folder or run Cypresss GUI to observe the issue.
  4. If the installExtensionFromFolder() test fails as the Joomla web server cannot find the mod_hello_world package folder, set the folder with the enviroment variable CYPRESS_SERVER_UPLOAD_FOLDER. For example on Unix-based systems: 
    export CYPRESS_SERVER_UPLOAD_FOLDER=/users/alice/joomla-cypress/tests/fixtures/mod_hello_world
  5. For Joomla development versions that are not yet been released, the tests installLanguage and installJoomlaMultilingualSite fail with the error message Unable to detect manifest file because the language packages are not yet available. Exclude these tests by setting an environment variable on Unix-based systems: 
    export CYPRESS_SKIP_INSTALL_LANGUAGES=1
