|
* Assertion is responsible for asserting it's actual value |
9
|
|
|
* against a MatcherInterface and responding to the results of a match. |
10
|
|
|
* |
11
|
|
|
* @method Assertion equal() equal(mixed $expected, string $message = "") Asserts that actual and expected values are strictly equal |
12
|
|
|
* @method Assertion with() with(array $args) Stores an array of values to be used with callable assertions |
13
|
|
|
* @method Assertion throw() throw(string $exceptionType, string $exceptionMessage = "", $message = "") Invokes the actual value as a function and matches the exception type was thrown, and optionally matches the exception message |
14
|
|
|
* @method Assertion a() a(string $expected, string $message = "") Asserts that the actual value given has the same type as the expected type string |
15
|
|
|
* @method Assertion an() an(string $expected, string $message = "") Asserts that the actual value given has the same type as the expected type string |
16
|
|
|
* @method Assertion include() include(mixed $expected, string $message = "") Asserts that the actual string or array includes the expected value |
17
|
|
|
* @method Assertion contain() contain(mixed $expected, string $message = "") Asserts that the actual string or array includes the expected value |
18
|
|
|
* @method Assertion ok() ok(string $message = "") Asserts that the actual value is truthy - that is true when cast to (bool) |
19
|
|
|
* @method Assertion true() true(string $message = "") Asserts that the actual value is strictly equal to true |
20
|
|
|
* @method Assertion false() false(string $message = "") Asserts that the actual value is strictly equal to false |
21
|
|
|
* @method Assertion null() null(string $message = "") Asserts that the actual value is null |
22
|
|
|
* @method Assertion empty() empty(string $message = "") Asserts that the actual value is empty |
23
|
|
|
* @method Assertion above() above(mixed $expected, string $message = "") Asserts that the actual value is greater than the expected value |
24
|
|
|
* @method Assertion least() least(mixed $expected, string $message = "") Asserts that the actual value is greater than or equal to the expected value |
25
|
|
|
* @method Assertion below() below(mixed $expected, string $message = "") Asserts that the actual value is less than the expected value |
26
|
|
|
* @method Assertion most() most(mixed $expected, string $message = "") Asserts that the actual value is less than or equal to the expected value |
27
|
|
|
* @method Assertion within() within(int $lowerBound, int $upperBound, string $message = "") Asserts that the actual value is between the upper and lower bounds (inclusive) |
28
|
|
|
* @method Assertion instanceof() instanceof(string $expected, string $message = "") Asserts that the actual value is an instance of the expected class string |
29
|
|
|
* @method Assertion property() property(string $name, mixed $value = "", string $message = "") Asserts that the actual array or object has the expected property and optionally asserts the property value against an expected value |
30
|
|
|
* @method Assertion length() length(mixed $expected, string $message = "") Asserts the actual array, string, or Countable has the expected length |
31
|
|
|
* @method Assertion match() match(string $pattern, string $message = "") Asserts that the actual value matches the expected regular expression |
32
|
|
|
* @method Assertion string() string(string $expected, string $message = "") Asserts that the actual string contains the expected substring |
33
|
|
|
* @method Assertion keys() keys(array $keys, string $message = "") Asserts the actual object or array has keys equivalent to the expected keys |
34
|
|
|
* @method Assertion satisfy() satisfy(callable $predicate, string $message = "") Asserts that the actual value satisfies the expected predicate. The expected predicate will be passed the actual value and should return true or false |
