FUnit: The testing microframework for PHP

FUnit is a testing microframework for PHP 5.3+, partially inspired by QUnit. FUnit was created by Ed Finkler for Fictive Kin.

If you can code PHP, you can write tests with FUnit.

Features

• Simple to write tests and get output – start writing tests fast
• Short, straightforward syntax
• Can be run from the CLI – no web server required
• Fancy colored output in terminal

Example

<?php
require __DIR__ . '/FUnit.php';
use \FUnit as fu;  // note the alias to "fu" for terseness

fu::test("this is a test", function() {
	fu::ok(1, "the integer '1' is okay");
	fu::ok(0, "the integer '0' is not okay"); // this will fail!
});

$exit_code = fu::run();
exit($exit_code);

Will output:

> php example_standalone.php
Running test 'this is a test...'
RESULTS:
--------------------------------------------
TEST: this is a test (1/2):
 * PASS ok() the integer '1' is okay
 * FAIL ok() the integer '0' is not okay

ERRORS/EXCEPTIONS: 0
TOTAL ASSERTIONS: 1 pass, 1 fail, 0 expected fail, 2 total
TESTS: 1 run, 0 pass, 1 total

See the example_standalone.php file for more, or try running it with php example_standalone.php

Alternately, if you load standalone_example.php in a web browser, it will output a very simple HTML version of the text report. If you're running PHP 5.4 or above, you can use the dev server to view it like so:

php -S 0.0.0.0:8000 example_standalone.php

And then open http://0.0.0.0:8000 in a web browser.

Methods

Test Suite Building Methods

• FUnit::test($name, \Closure $test)
  Add a test with the name $name and an anonymous function $test. $test would contain various assertions, like FUnit::ok()

• FUnit::run($report = true, $filter = null, $report_format = 'text')
  Runs the registered tests.

  • $report (boolean): If false is passed, the report output is suppressed.
  • $filter (string): If this is passed, only tests that contain the $filter string will be run.
  • $report_format (string): Default is 'text'. Also accepts 'xunit'.

• FUnit::setup(\Closure $setup)
  Register a function to run at the start of each test. See FUnit::fixture()

• FUnit::teardown(\Closure $setup)
  Register a function to run at the end of each test. See FUnit::fixture() and FUnit::reset_fixtures()

• FUnit::fixture($key, [$val])
  Retrieve or register a fixture. Use this in FUnit::setup() to assign fixtures to keys, and retrieve those fixtures in your tests

• FUnit::reset_fixtures()
  Clears out all fixtures in the FUnit::$fixtures array. This doesn't guarantee clean shutdown/close

Assertions

• FUnit::ok($a, $msg = null)
  Assert that $a is truthy. Optional $msg describes the test

• FUnit::not_ok($a, $msg = null)
  Assert that $a is not truthy. Optional $msg describes the test

• FUnit::equal($a, $b, $msg = null)
  Assert that $a == $b. Optional $msg describes the test

• FUnit::not_equal($a, $b, $msg = null)
  Assert that $a != $b. Optional $msg describes the test

• FUnit::strict_equal($a, $b, $msg = null)
  Assert that $a === $b. Optional $msg describes the test

• FUnit::not_strict_equal($a, $b, $msg = null)
  Assert that $a !== $b. Optional $msg describes the test

• FUnit::has($needle, $haystack, $msg = null)
  Assert that an array or object ($haystack) has a key or property ($needle)

• FUnit::not_has($needle, $haystack, $msg = null)
  Assert that an array or object ($haystack) does not have a key or property ($needle). Forgive my grammar.

• FUnit::fail($msg = null, [$expected = null])
  Force a failed assertion. If $expected === true, it's marked as an expected failure

• FUnit::expect_fail($msg = null)
  Assets an expected failure. Equivalent to FUnit::fail('msg', true)

• FUnit::pass($msg = null)
  Force a successful assertion.

• FUnit::throws($callback, $params, $exception = null, $msg = null)
  Assert that $callback throws an exception of type $exception. $callback must be a callable

• FUnit::all_ok($a, $callback, $msg = null)
  Iterate over all the items in $a and pass each to $callback. If the callback returns true for all, it passes -- otherwise it fails. $callback must be a callable

Utility Methods

• FUnit::report($format = 'text')
  Output the test report. If you've suppressed reporting output previously, you can use this to output the report manually.

• FUnit::exit_code()
  Retrieve the exit code. If any test fails, the exit code will be set to 1. Otherwise 0. You can use this value to return a success or failure result with the PHP function exit().

Configuration Methods

• FUnit::set_disable_reporting($state)
  If passed true, report will not be output after test runs finish. Re-enable by passing false.

• FUnit::set_debug($state)
  If passed true, extra debugging info (including timing and details about assertion failures) will be output. Disable by passing false.

• FUnit::set_silence($state)
  If passed true, only the report will be output -- no progress, debugging info, etc. Disable by passing false.

Report formats

By default, FUnit outputs a colorful text output, formatted for the terminal. You can also output reports in xunit-style xml.

The report format is the third parameter of FUnit::run():

Example:

// Outputs a colored text report. This is the default format.
FUnit::run(true, null, 'text');

// Outputs xUnit-style xml
FUnit::run(true, null, 'xunit');

Browser output

The standard text report format will output as very simple HTML if the test file is loaded up through a web server. You can test this with the dev server if you're running PHP 5.4+:

php -S 0.0.0.0:8000 test_file.php

And then open http://0.0.0.0:8000 in a web browser.

CLI Test Runner Utility

FUnit was designed to not require a separate test runner tool, but it does come with one at bin/fu (or vendor/bin/fu if you've installed via Composer). fu allows you to run tests in a single file, a group of files in a directory, and filter what tests are run.

Examples:

• fu --help
  Get detailed help and information on all options

• fu ./tests
  Scan the directory ./tests for files that have "test(s)" in their names, and run those tests

• fu tests.php
  Execute tests in tests.php

• fu -d tests.php
  Execute tests in tests.php with additional debugging info

• fu --filter="API" tests.php
  Execute only the tests in tests.php that have "API" in the name

• fu -s tests.php
  Execute the tests tests.php, but suppress all output other than the report

Note: When fu loads multiple test files, it requires each one. That means all the code within each is executed. Calls to FUnit::run() are suppressed, but non-FUnit code (like exit() calls or require statements) could cause issues.

Installation

Install with Composer

If you're using Composer to manage dependencies, you can add FUnit with it.

{
	"require": {
		"funkatron/funit": "dev-master"
	}
}

Note that FUnit has not yet reached 1.0! That means BC may break!

If you install via Composer, you can use the auto-generated autoloader to load FUnit, like so:

<?php
require "vendor/autoload.php"
use \FUnit as fu;

fu::test("this is a test", function() {
    fu::ok(1, "the integer '1' is okay");
    fu::ok(0, "the integer '0' is not okay"); // this will fail!
});

fu::run();

Install source from GitHub

To install the source code:

git clone git://github.com/funkatron/FUnit.git

And include it in your scripts:

require_once '/path/to/FUnit/FUnit.php';

Install source from zip/tarball

Alternatively, you can fetch a tarball or zipball:

$ curl https://github.com/funkatron/FUnit/tarball/master | tar xzv
(or)
$ wget https://github.com/funkatron/FUnit/tarball/master -O - | tar xzv

Using a Class Loader

If you're using a class loader (e.g., Symfony Class Loader) for PSR-0-style class loading:

$loader->registerNamespace('FUnit', 'path/to/vendor/FUnit');

Upgrading

If you're using a version older than 0.5, the namespace/class name changed to follow PSR-0 autoloader standards. The base class is now \FUnit, not \FUnit\fu. You can still call all your methods with fu::XXX() by aliasing the namespace like so:

use \FUnit as fu
