README

Expect is a BDD-style assertion library for PHP - allowing you to express expectations using a natural, fluent interface.

// equality
expect(1)->toEqual('1');
expect(2)->toBe(2);

// comparison
expect(5)->toBeLessThan(7);
expect(5)->toBeLessThanOrEqualTo(5);
expect(5)->toBeGreaterThan(4);
expect(5)->toBeGreaterThanOrEqualTo(5);

// true / false / null
expect(true)->toBeTrue();
expect('1')->toBeTruthy();
expect(false)->toBeFalse();
expect('0')->toBeFalsy();
expect(null)->toBeNull();

// strings
expect('string')->toContain('in');
expect('string')->toStartWith('str');
expect('string')->toEndWith('ing');
expect('string')->toHaveLength(6);
expect('string')->toMatchPattern('/string/');
expect('string')->toMatchFormat('%s');

// arrays
expect(['a', 'b', 'c'])->toHaveCount(3);
expect(['a', 'b', 'c'])->toContain('a');
expect(['key' => 'value'])->toHaveKey('key');

// types
expect(1)->toBeType('int');
expect(new Example())->toBeInstanceOf(Example::class);
expect('{"key": "value"}')->toBeJson();
expect('<key>value</key>')->toBeXml();

// files
expect('file.txt')->toExist();

// negation
expect(1)->not()->toEqual(2);
expect(true)->not()->toBeFalse();
expect($value)->not()->toBeNull();

Thanks

Expect was built atop Verify and heavily inspired by RSpec and Jasmine. I want to recognize and thank these projects.
