Test PHP applications
The topics in this part provide guidelines in PHP-specific unit testing procedures. For general information on testing in IntelliJ IDEA, see the section Run tests.
IntelliJ IDEA supports unit testing of PHP applications through integration with the PHPUnit testing framework.
Generally, IntelliJ IDEA runs and debugs PHPUnit tests same way as other applications, by running the run/debug configurations you have created. When doing so, it passes the specified test class, file, or directory to the test runner. You can run unit testing locally and remotely depending on the chosen run configuration.
Install the PHP plugin
This functionality relies on the PHP plugin, which you need to install and enable.
Press Control+Alt+S to open the IDE settings and then select.
Open the Marketplace tab, find the PHP plugin, and click Install (restart the IDE if prompted).
Create and run unit tests on PHP applications, perform the following general steps:
Write the unit tests to run.
Group the test to distinguish between testing in a production and in your development environment or to enable filtering tests by their authors.
Launch unit tests with coverage by clicking the Run with coverage toolbar button and analyze the test coverage in the Coverage tool window.
Debug unit tests by setting breakpoints where necessary and clicking Debug . For more information, refer to PHP debugging session.
