atoum/praspel-extension

This extension introduces Praspel inside atoum.

atoum is a simple, modern and intuitive unit testing framework for PHP!

Hoa is a modular, extensible and structured set of PHP libraries. Moreover, Hoa aims at being a bridge between industrial and research worlds.

Installation

With Composer, to include this library into your dependencies, you need to require atoum/praspel-extension:

composer require --dev atoum/praspel-extension

Please, read the website to get more informations about how to install.

And to activate the extension, add this line on your .atoum.php configuration file:

$runner->addExtension(new \Atoum\PraspelExtension\Manifest());

Quick usage

This extension brings two aspects into atoum: automatic test data generation (from Hoa\Realdom) and automatic test suite generation (from Hoa\Praspel, which relies on Hoa\Realdom).

Automatic test data generation

[more explications needed] We will use three asserters to generate data and one to validate data:

1. realdom to create a realistic domains disjunction,
2. sample to generate one data from a realistic domains disjunction,
3. sampleMany to generate several data,
4. predicate to validate a data against a realistic domains disjunction.

As an example, we are going to generate an integer defined by: [7; 13] ∪ [42; 153]:

$this->sample($this->realdom->boundinteger(7, 13)->or->boundinteger(42, 153))

We can obviously use the classical asserters from atoum:

foreach ($this->sampleMany($this->realdom->boundinteger(-5, 5), 1024) as $i) {
    $this->integer($i)->isGreaterThan(0);
}

(this example is a little dummy ;-)).

We can generate more sophisticated data (please, see the standard realistic domain library in Hoa\Realdom), such as strings based on regular expressions (and also grammars):

$data = $this->realdom->regex('/[\w\-_]+(\.[\w\-\_]+)*@\w\.(net|org)/');
$this->string($this->sample($data))
     ->contains(…)->…;

Or even dates:

$data = $this->realdom->date(
    'd/m H:i',
    $this->realdom->boundinteger(
        $this->realdom->timestamp('yesterday'),
        $this->realdom->timestamp('next Monday')
    )
);

foreach ($this->sampleMany($data, 10) as $date) {
    var_dump($date);
}

Automatic test suite generation

We will use the Bin/praspel binary script. [TODO]
