HackTest

Build Status

HackTest is a unit test runner and base class. Assertions are provided by separate libraries, such fbexpect.

Installation

php /path/to/composer.phar require --dev hhvm/hacktest facebook/fbexpect

Usage

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 {
  ....
}

Examples

"I want to test all files in a directory"

$ vendor/bin/hacktest tests/clean/exit/

...

Summary: 3 test(s), 3 passed, 0 failed, 0 skipped, 0 error(s).

"I want to run all tests in a specific file"

$ vendor/bin/hacktest tests/dirty/DirtyAsyncTest.php
