Lando + PHPStorm/IntelliJ IDEA + PHPUnit

Context

This gist is a follow-up to this Lando issue, updated for Docker Composer and Windows (but might also help macOS and Linux users).

Steps

Setup Docker

1. Open File | Settings | Build, Execution, Deployment | Docker
2. Click on the top-left "+"
3. Case a: If you have (and want to use) Docker for Windows: choose "Docker for Windows"
4. Case b (theorical, because unfortunately I could not get it to work): If your Lando instance is in WSL:
   1. Choose "WSL" and your Linux distribution
   2. Add one or more path mappings (in my case mapping /home/quentint to \\wsl$\Ubuntu\home\quentint was enough because my projects are stored in WSL's home directory)

PHP CLI Interpreter

1. Open File | Settings | Languages & Frameworks | PHP

2. Click on the three dots on the "CLI Interpreter" line
3. Click on the top-left "+" and create CLI Interpreter "From Docker, Vagrant, VM, WSL, Remote..."

4. Choose "Docker Compose"

5. Click on the "Configuration files" folder icon
6. Click on the top-right "+"

7. Select all YAML files in C:\Users\[user]\.lando\compose\[project]
8. Select "appserver" in the Service dropdown
9. Click OK to close the "Configure Remote PHP Interpreter" window
10. Choose "Connect to an existing container" in the "Lifecycle" section

11. Click OK to close the "CLI Interpreters" window
12. Click on the directory icon of the "Path mappings" section
13. Add a local path mapping your project root to /app and click OK to confirm

PHPUnit

1. Open File | Settings | Languages & Frameworks | PHP | Test Frameworks
2. Click the top-left "+" to add a test framework
3. Choose "PHPUnit by Remote Interpreter"
4. Choose your newly created interpreter and click OK to close the window

When using Composer (you should)

1. Choose "Use Composer autoloader"
2. Set "Path to script" to /app/vendor/autoload.php

When using Symfony

1. If not already there, create phpunit.xml.dist at the root of your project

<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.readthedocs.io/en/latest/configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.3/phpunit.xsd" backupGlobals="false" colors="true"
         bootstrap="tests/bootstrap.php">
    <coverage processUncoveredFiles="true">
        <include>
            <directory suffix=".php">src</directory>
        </include>
    </coverage>
    <php>
        <ini name="error_reporting" value="-1"/>
        <server name="APP_ENV" value="test" force="true"/>
        <server name="SHELL_VERBOSITY" value="-1"/>
    </php>
    <testsuites>
        <testsuite name="Project Test Suite">
            <directory>tests</directory>
        </testsuite>
    </testsuites>
    <!-- Run `composer require symfony/phpunit-bridge` before enabling this extension -->
    <!--
      <listeners>
          <listener class="Symfony\Bridge\PhpUnit\SymfonyTestsListener" />
      </listeners>
      -->
    <!-- Run `composer require symfony/panther` before enabling this extension -->
    <!--
      <extensions>
          <extension class="Symfony\Component\Panther\ServerExtension" />
      </extensions>
      -->
</phpunit>

2. If not present, add KERNEL_CLASS='App\Kernel' to your .env.test file
3. Open previous settings (File | Settings | Languages & Frameworks | PHP | Test Frameworks)
4. Check "Default configuration file"
5. Set path to /app/phpunit.xml.dist

Add Xdebug support

See this comment for detailed steps.

Run tests 😊

Great success! 😄
It works for me now. I wish I could tell you what the problem was, but I don't know. In the meantime, my Linux kernel, Docker, PhpStorm etc. were updated. Maybe one of those was the problem. Anyway, the above approach works now and I am able to select appserver in the Service dropdown.

Also thanks to @mortona42 , the file permission problem is gone. To my surprise, it was not enough that the test ran through docker compose. The file created was still owned by root.
To recap: if you set up your test runner like this...

... any file created during testing will be owned by your (host) user and not root. The same way it works if you run lando phpunit.

The last problem is that PhpStorm tries to create the Clover XML in a dir that does not exist.

Generating code coverage report in Clover XML format ... failed [00:00.008]
Directory "/opt/phpstorm-coverage" could not be created

As you can see in the above screenshot, I tried setting a path for the XML report, but it's just ignored and PhpStorm appends another one with the problematic path.

I can't find any option how to properly set this path. 😏

Path mappings are in the docker server settings:

Isn't that path already mapped by Lando?
Trying this more portable solution from PhpStorm forums, I added it in service volumes like this and it works.

services:
  appserver:
    type: php:8.1
    via: cli
    webroot: .
    xdebug: "debug,coverage,develop"
    volumes:
      # Add directory for PhpStorm coverage XML report
      - ./build/coverage/xml/:/opt/phpstorm-coverage/

However it's strange that I see it as empty on the host, while files are present in the container.

It goes to show that I am still a Docker newb 😅

I haven't tried to use coverage so I'm not sure if that's a hardcoded path or something. I was seeing /opt paths in the command phpstorm was running if I didn't set the path mapping.
