# PHPUnit for VSCode 3.0: VS Code Testing API and Docker

*Originally published at [recca0120.github.io](https://recca0120.github.io/en/2022/12/06/rebuilt-phpunit-for-vscode/)*

VSCode released a new Testing API, and the 2.0 version wasn't designed with Docker and SSH use cases in mind, so I completely rewrote [PHPUnit For VSCode](https://marketplace.visualstudio.com/items?itemName=recca0120.vscode-phpunit).

## Improvements in 3.0

**VSCode Testing API Integration**: The test list shows directly in the VSCode sidebar, and error messages are displayed inline in the editor.

**PHPUnit Output Formatting**: Switched to parsing the TeamCity protocol, reporting results in real time as each TestCase completes, unlike 2.0 which required waiting for the entire run to finish.

**Docker Support**:

```json
{
  "phpunit.command": "docker run --rm -t -v ${pwd}:/app -w /app php:latest php",
  "phpunit.php": "php",
  "phpunit.phpunit": "vendor/bin/phpunit",
  "phpunit.args": [
    "-c",
    "phpunit.xml"
  ],
  "phpunit.paths": {
    "${workspaceFolder}": "/app"
  }
}
```

**SSH Support**:

```json
{
  "phpunit.command": "ssh -i dockerfiles/sshd/id_rsa -p 2222 root@localhost -o StrictHostKeyChecking=no",
  "phpunit.php": "php",
  "phpunit.phpunit": "/app/vendor/bin/phpunit",
  "phpunit.args": [
    "-c",
    "/app/phpunit.xml"
  ],
  "phpunit.paths": {
    "${workspaceFolder}": "/app"
  }
}
```
