HackTest is a unit test runner and base class. Assertions are provided by separate libraries, such fbexpect.
php /path/to/composer.phar require --dev hhvm/hacktest facebook/fbexpect
To run tests:
vendor/bin/hacktest [OPTIONS] tests/
Tests are methods in classes, where:
- the class name matches the file name
- the class name ends with 'Test'
- the method is public
- the method name begins with 'test'
Test methods can be async, and will automatically be awaited.
Additionally, classes can implement several special methods:
public static function beforeFirstTestAsync(): Awaitable<void>public static function afterLastTestAsync(): Awaitable<void>public function beforeEachTestAsync(): Awaitable<void>public function afterEachTestAsync(): Awaitable<void>
Finally, for data-driven tests, the <<DataProvider>> attribute can be used:
public function provideFoos(): vec<(string, int)> {
return vec[
tuple('foo', 123),
tuple('bar', 456),
];
}
<<DataProvider('provideFoos')>>
public function testFoos(string $a, int $b): void {
