ExtraMatchers::register();

toBeOneOf($expected) // strict comparison

it("passes if $actual is present in $expected", function() {
    expect(3)->toBeOneOf([1, 2, 3]);
});

toEqualOneOf($expected) // loose comparison

it("passes if $actual is present in $expected", function() {
    expect("3")->toEqualOneOf([1, 2, 3]);
});

toImplement($expected) // object implements expected interface

namespace App\Spec;

it("passes if $actual implements $expected", function() {

    interface Foo { }
    class Bar implements Foo {}

    $actual = new Bar();
    expect($actual)->toImplement('App\Spec\Foo');
});
