Collection of phpspec Matchers
This package contains a collection of additional phpspec matchers.
Installation
You can install the package via composer
composer require karriere/phpspec-matchers
To be able to use the matchers you need to add the following definition to your phpspec.yml
extensions: Karriere\PhpSpecMatchers\Extension: ~
Matcher Usage
All custom matchers in this package implement the positive and the negative case. For example you can use:
$this->method()->shouldBeAnyOf(1, 2, 3);
and also
$this->method()->shouldNotBeAnyOf(1, 2, 3);
Matchers
General Matchers
Json Matchers
General Matchers
beAnyOf
This matcher allows to check the return value against a set of values.
Assume you have some sort of random mechanism to get an integer between 2 and 4. The you can use the shouldBeAnyOf
matcher:
$this->method()->shouldBeAnyOf(2, 3, 4);
beSomeOf
This matcher allows to check if the returned array values are contained in a set of values.
// $this->method() may return [1, 2, 3] $this->method()->shouldBeSomeOf(1, 2, 3, 4, 5);
rangeBetween
This matcher allows to check if the given return value is inside a numeric range.
$this->method()->shouldRangeBetween(2, 4); $this->method()->shouldRangeBetween(0.1, 0.9);
beEmpty
This matcher allows to check if the given return value is empty. The implementation uses the empty implementation.
$this->method()->shouldBeEmpty();
beNull
This matcher allows to check if the given return value is null. The implementation uses the is_null implementation.
$this->method()->shouldBeNull();
beLessThan
This matcher allows to check if the given return value is less than a specified value.
$this->method()->shouldBeLessThan(10);
beGreaterThan
This matcher allows to check if the given return value is greater than a specified value.
$this->method()->shouldBeGreaterThan(10);
Json Matchers
beJson
This matcher checks if the return value is a valid json string
$this->method()->shouldBeJson();
haveJsonKey
This matcher checks if the returned json string contains a json key.
$this->method()->shouldHaveJsonKey('key');
To match against subkey you can use the dot notation. For example let's assume the following json structure
{ "key": { "subkey": "value" } }
The key for this check is 'key.subkey'
$this->method()->shouldHaveJsonKey('key.subkey');
haveJsonKeyWithValue
This matcher checks if the returned json string contains the json key and the desired value. The dot syntax for subkeys can also be applied.
$this->method()->shouldHaveJsonKeyWithValue('key.subkey', 'value');
