# Debugging CiviCRM cheatsheet

### Command-line runs of PHPUnit:

From a buildkit civiroot, run a specific file's tests::

```shell

CIVICRM_UF=UnitTests phpunit5 tests/phpunit/CRM/Core/BAO/AddressTest.php

```

You can also limit to a single test by filtering on name:

```shell

CIVICRM_UF=UnitTests phpunit5 tests/phpunit/CRM/Core/BAO/AddressTest.php --filter testShared

```

### With XDebug

#### Web Browser

* Install the xdebug extension (e.g. `sudo apt install php7.4-xdebug`).

* Configure xdebug by copying the values below to `/etc/php/7.4/fpm/conf.d/xdebug.ini`:

```

xdebug.mode=debug,develop

xdebug.start_with_request=trigger

xdebug.client_port=9000

xdebug.client_host = "127.0.0.1"

xdebug.log=/var/log/xdebug.log

#xdebug.mode=profile

#xdebug.output_dir = "/home/jon/temp/xdebug"

```

* Install a plugin for your browser, like "XDebug Helper for Firefox".

 * In the plugin's configuration, set the IDE key to `VSCODE`.

* If one does not already exist, create a launch.json file within the .vscode folder (make a new folder if it does not yet exist) at the root of your codebase. What goes into the launch.json file depends on whether you are debugging a a site created with the `civibuild` command or one that was not built with that command. Here are examples of a [civibuild launch.json](https://hq.megaphonetech.com/projects/commons/wiki/Launchjson_for_civibuild_sites) and a [non-civibuild launch.json](https://hq.megaphonetech.com/projects/commons/wiki/Launchjson_for_non-civibuild_sites). Note that the "max-depth" on the "Listen for XDebug" configuration can be changed to delve deeper into the values that are returned (i.e. a depth of 6 will return more levels of a nested array than a depth of 3).

To debug, you must turn on the debugger in VS Code, then enable debugging in the address bar for the requests in question.

#### civicrm-buildkit (mod_php)

The instructions above assume php-fpm.  To also debug mod_php (e.g. civicrm-buildkit), do the following:

* Use the same configuration file as under "Web Browser", but at `/etc/php/7.4/apache2/conf.d/xdebug.ini`.

* Edit `/etc/php/7.4/apache2/conf.d/xdebug.ini` and change the client port from `9000` to `9001`.

#### Command Line (phpunit)

* You need to have XDebug otherwise configured for CLI.  Use the same configuration file as under "Web Browser", but at `/etc/php/7.4/cli/conf.d/xdebug.ini`.

 * Also change `xdebug.mode=debug,develop` to avoid some unnecessary warning noise.

* You need to start a debugging session in VS Code with "Listen for XDebug".

* Depending on your VS Code setup, you may need to listen on a different port (I can use the same port for FPM but not mod_php).

Once you've got all that:

```shell

env CIVICRM_UF=UnitTests XDEBUG_SESSION=VSCODE phpunit7 /home/jon/local/civicrm-buildkit/build/dmaster/web/sites/all/modules/civicrm/tests/phpunit/CRM/Core/BAO/ActionScheduleTest.php --filter testMembershipJoinDateMinutesUnit

```

### Command-line runs of standalone scripts

```shell

env XDEBUG_SESSION=VSCODE php myscript.php

```

### Debugging REST API calls in Ansible/curl

Add an additional POST argument `XDEBUG_SESSION=VSCODE`.  In curl, just add `-d 'XDEBUG_SESSION=VSCODE'` anywhere in your command.

For Ansible, this might look like:

```yaml

  - name: Shut up about Civi extensions (warnings only, 7 days)

    uri:

      url: "{{ primary_url }}/{{ endpoint }}"

      method: POST

      body:

        XDEBUG_SESSION: VSCODE

        entity: StatusPreference

        action: create

        json: "{{ {'name': 'checkExtensionsUpdates', 'ignore_severity': 3, 'hush_until': seven_days_hence } | to_json }}"

        api_key: "{{ crm_api_key }}"

        key: "{{ crm_site_key }}"

      body_format: form-urlencoded

      return_content: yes

```
