Functional Test Scripts

This folder contains the PHP scripts that produce the output for the functional tests.

They can also be run from the command-line to provide a visual representation of xdebug-handler's inner workings.

Usage

There are two core scripts, app-basic which includes xdebug-handler, and app-plain which does not.

cd tests/App

php app-basic.php --display
php app-plain.php --display

The --display options provides colorized output with a detailed list of xdebug-handler values:

  • [active] - from isXdebugActive()
  • [skipped] - from getSkippedVersion()
  • [env] - environment variables (PHPRC and PHP_INI_SCAN_DIR)
  • [ini] - from getAllIniFiles(). Use the --inis options to show them all.
  • [settings] - from getRestartSettings()

These values are obtained after any restart has happened.

Each line of output is prefixed name[pid], where name is either 'logger' (for xdebug-handler's internal logger) or the name of the script, and pid is the process identifier.

Scripts

The following scripts are in addition to the core scripts (which are used by some of these).

app-extend-allow

Demonstrates how an extended class can decide whether to restart or not.

cd tests/App

# restarts if no help command or option
php app-extend-allow.php --display

# no restart with -h, --help or help
php app-extend-allow.php -h --display

app-extend-ini

Demonstrates how an extended class can restart with a specific ini setting, even if xdebug is not loaded. The phar_readonly ini setting is used in this example.

cd tests/App

php -dphar.read_only=1 app-extend-ini.php --display

app-extend-mode

Demonstrates how xdebug can be restarted in a different mode, in this example xdebug.mode=coverage.

cd tests/App

php -dxdebug.mode=develop app-extend-mode.php --display

app-persistent

Demonstrates the use of persistent settings (to remove xdebug from all sub-processes) and PhpConfig to enable xdebug when required. The following sub-processes are called:

  • app-plain.php (xdebug not loaded)
  • app-plain.php with original settings (xdebug will be loaded)
  • app-other.php (xdebug not loaded)
php app-persistent.php --display

app-prepend

Demonstrates the use of an auto prepend file to remove xdebug from a script. Note that either app-basic or app-plain can be used here.

cd tests/App

php -dauto_prepend_file=app-prepend.php app-plain.php --display

The auto_prepend_file ini setting from the command-line is picked up when the ini content is merged, so it is available in the restart.

If stdin is used, it will be read in the restart:

# Unixy
cat app-plain.php | php -dauto_prepend_file=app-prepend.php -- --display

# Windows
type app-plain.php | php -dauto_prepend_file=app-prepend.php -- --display

app-stdin

Included here for demonstration purposes only.

Uses xdebug-handler from stdin to remove xdebug from a script. Note that either app-basic or app-plain can be used here.

cd tests/App

# Unixy
cat app-stdin.php | php -- app-plain.php --display

# Windows
type app-stdin.php | php -- app-plain.php --display

While this works in simple scenarios, it is not recommended because the restart settings are not available. This is due to a different script restarting, thus preventing app-stdin from setting the restart environment variable.

Additionally getAllIniFiles() returns the temp ini used in the restart, because the restarting script is not looking for its own named environment variable.
