Humbug PHPSpec Extensions

A collection of extensions intended to allow for:

• Timing of specification and example execution
• Freeing of memory by removing specification properties after execution
• Filter/Reorder both specifications and examples using custom filters

Available phpspec.yml options (see usable examples below):

formatter.name: pretty
humbug.filtered_resource_loader.filters:
- Humbug\PhpSpec\Loader\Filter\Specification\FastestFirstFilter
- Humbug\PhpSpec\Loader\Filter\Specification\ShuffleFilter
- Humbug\PhpSpec\Loader\Filter\Example\ShuffleFilter
humbug.time_collector.target: /tmp/phpspec.times.humbug.json
extensions:
- Humbug\PhpSpec\TimeCollectorExtension
- Humbug\PhpSpec\FilteredResourceLoaderExtension
- Humbug\PhpSpec\FreeMemoryExtension

This is for illustrative purposes only to show all options. See the usage examples below for working combinations of options. Generally, you can write separate yml files and load them selectively using phpspec's -c option. Filters are applied in the order listed in the configuration, so technically the FastestFirstFilter would be undone by the ShuffleFilter for specs in the above. All filters are supplied a referenced array of either examples or specifications to play with.

These extensions are primarily targeted at Humbug, but are reusable/extendable for any other purpose. Knock yourself out!

Installation

require: {
   "padraic/phpspec-extensions": "dev-master"
}

Usage Examples

Free memory after running a specification. This clears out any non phpspec properties on the class which may improve performance somewhat:

formatter.name: pretty
extensions:
- Humbug\PhpSpec\FreeMemoryExtension

Generate timing data for any timing related filters (run prior to activating such filters):

formatter.name: pretty
humbug.time_collector.target: /tmp/phpspec.times.humbug.json
extensions:
- Humbug\PhpSpec\TimeCollectorExtension
- Humbug\PhpSpec\FreeMemoryExtension

Use the timing to run specifications fastest first:

formatter.name: pretty
humbug.filtered_resource_loader.filters:
- Humbug\PhpSpec\Loader\Filter\Specification\FastestFirstFilter
humbug.time_collector.target: /tmp/phpspec.times.humbug.json
extensions:
- Humbug\PhpSpec\FilteredResourceLoaderExtension
- Humbug\PhpSpec\FreeMemoryExtension

Worried about any odd inter-example or inter-specification dependencies? Root them out by shuffling examples and specifications. Specification position in a suite, or example position in a specification, will be randomly distributed.
