FBExpect is a standalone unit testing utility based on the notion of assertions from PHPUnit. Starting with 2.x, FBExpect no longer uses PHPUnit as a
dependency, and instead implements the assertions directly, and is intentended
for use with HackTest.
It is linguistically clear which value is the expected value and which is the actual value:
use function Facebook\FBExpect\expect;
// PHPUnit
$this->assertSame($a, $b);
// FBExpect
expect($b)->toBeSame($a);use function Facebook\FBExpect\expect;
// PHPUnit
$this->assertNotNull($x); // Actual test
assert($x !== null); // Tell the typechecker what's going on
$this->assertInstanceOf(Foo::class, $y);
assert($y instanceof Foo);
// FBExpect
$x = expect($x)->toNotBeNull();
$y = expect($y)->toBeInstanceOf(Foo::class);FBExpect is installed via composer:
composer require facebook/fbexpect
Composer must be executed with php, not HHVM.
FBExpect is MIT-licensed.
