It's used by the [Nette Framework](https://nette.org) and is capable of testing any PHP code. Documentation is available on the [Nette Tester website](https://tester.nette.org). Read the [blog](https://blog.nette.org/category/tester/) for new information. [Support Tester](https://github.com/sponsors/dg) ------------------------------------------------ [](#support-tester) Do you like Nette Tester? Are you looking forward to the new features? [![Buy me a coffee](https://camo.githubusercontent.com/afa7c20ccaac10ac4f1f51669bafb212856b932e0c8b276cb290336cf08624b8/68747470733a2f2f66696c65732e6e657474652e6f72672f69636f6e732f646f6e6174696f6e2d332e737667)](https://github.com/sponsors/dg) Thank you! Installation ------------ [](#installation) The recommended way to install Nette Tester is through Composer: ``` composer require nette/tester --dev ``` Alternatively, you can download the [tester.phar](https://github.com/nette/tester/releases) file. Nette Tester 2.6 is compatible with PHP 8.0 to 8.5. Collecting and processing code coverage information depends on Xdebug or PCOV extension, or PHPDBG SAPI. Writing Tests ------------- [](#writing-tests) Imagine that we are testing this simple class: ``` class Greeting { function say($name) { if (!$name) { throw new InvalidArgumentException('Invalid name.'); } return "Hello $name"; } } ``` So we create test file named `greeting.test.phpt`: ``` require 'src/bootstrap.php'; use Tester\Assert; $h = new Greeting; // use an assertion function to test say() Assert::same('Hello John', $h->say('John')); ``` Thats' all! Now we run tests from command-line using the `tester` command: ``` > tester _____ ___ ___ _____ ___ ___ |_ _/ __)( __/_ _/ __)| _ ) |_| \___ /___) |_| \___ |_|_\ v2.6 PHP 8.2.0 | php | 8 threads . OK (1 tests, 0 skipped, 0.0 seconds) ``` Nette Tester prints dot for successful test, F for failed test and S when the test has been skipped. Assertions ---------- [](#assertions) This table shows all assertions (class `Assert` means `Tester\Assert`): - `Assert::same($expected, $actual)` - Reports an error if $expected and $actual are not the same. - `Assert::notSame($expected, $actual)` - Reports an error if $expected and $actual are the same. - `Assert::equal($expected, $actual)` - Like same(), but identity of objects and the order of keys in the arrays are ignored. - `Assert::notEqual($expected, $actual)` - Like notSame(), but identity of objects and arrays order are ignored. - `Assert::contains($needle, array $haystack)` - Reports an error if $needle is not an element of $haystack. - `Assert::contains($needle, string $haystack)` - Reports an error if $needle is not a substring of $haystack. - `Assert::notContains($needle, array $haystack)` - Reports an error if $needle is an element of $haystack. - `Assert::notContains($needle, string $haystack)` - Reports an error if $needle is a substring of $haystack. - `Assert::true($value)` - Reports an error if $value is not true. - `Assert::false($value)` - Reports an error if $value is not false. - `Assert::truthy($value)` - Reports an error if $value is not truthy. - `Assert::falsey($value)` - Reports an error if $value is not falsey. - `Assert::null($value)` - Reports an error if $value is not null. - `Assert::nan($value)` - Reports an error if $value is not NAN. - `Assert::type($type, $value)` - Reports an error if the variable $value is not of PHP or class type $type. - `Assert::exception($closure, $class, $message = null, $code = null)` - Checks if the function throws exception. - `Assert::error($closure, $level, $message = null)` - Checks if the function $closure throws PHP warning/notice/error. - `Assert::noError($closure)` - Checks that the function $closure does not throw PHP warning/notice/error or exception. - `Assert::match($pattern, $value)` - Compares result using regular expression or mask. - `Assert::matchFile($file, $value)` - Compares result using regular expression or mask sorted in file. - `Assert::count($count, $value)` - Reports an error if number of items in $value is not $count. - `Assert::with($objectOrClass, $closure)` - Executes function that can access private and protected members of given object via $this. Testing exceptions: ``` Assert::exception(function () { $h = new Greeting; $h->say(null); }, InvalidArgumentException::class, 'Invalid name.'); ``` Testing PHP errors, warnings or notices: ``` Assert::error(function () { $h = new Greeting; echo $h->abc; }, E_NOTICE, 'Undefined property: Greeting::$abc'); ``` Testing private access methods: ``` $h = new Greeting; Assert::with($h, function () { // normalize() is internal private method. Assert::same('Hello David', $this->normalize('Hello david')); // $this is Greeting }); ``` Tips and features ----------------- [](#tips-and-features) Running unit tests manually is annoying, so let Nette Tester to watch your folder with code and automatically re-run tests whenever code is changed: ``` tester -w /my/source/codes ``` Running tests in parallel is very much faster and Nette Tester uses 8 threads as default. If you wish to run the tests in series use: ``` tester -j 1 ``` How do you find code that is not yet tested? Use Code-Coverage Analysis. This feature requires you have installed [Xdebug](https://xdebug.org/) or [PCOV](https://github.com/krakjoe/pcov)extension, or you are using PHPDBG SAPI. This will generate nice HTML report in `coverage.html`. ``` tester . -c php.ini --coverage coverage.html --coverage-src /my/source/codes ``` We can load Nette Tester using Composer's autoloader. In this case it is important to setup Nette Tester environment: ``` require 'vendor/autoload.php'; Tester\Environment::setup(); ``` We can also test HTML pages. Let the [template engine](https://latte.nette.org) generate HTML code or download existing page to `$html` variable. We will check whether the page contains form fields for username and password. The syntax is the same as the CSS selectors: ``` $dom = Tester\DomQuery::fromHtml($html); Assert::true($dom->has('input[name="username"]')); Assert::true($dom->has('input[name="password"]')); ``` For more inspiration see how [Nette Tester tests itself](https://github.com/nette/tester/tree/master/tests). Running tests ------------- [](#running-tests) The command-line test runner can be invoked through the `tester` command (or `php tester.php`). Take a look at the command-line options: ``` > tester Usage: tester [options] [ | ]... Options: -p Specify PHP interpreter to run (default: php). -c Use custom php.ini, ignore system configuration. -C With -c, include system configuration as well. -l | --log Write log to file . -d ... Define INI entry 'key' with value 'val'. -s Show information about skipped tests. --stop-on-fail Stop execution upon the first failure. -j Run jobs in parallel (default: 8). -o Specify output format. -w | --watch Watch directory. -i | --info Show tests environment info and exit. --setup Script for runner setup. --temp Path to temporary directory. Default by sys_get_temp_dir(). --colors [1|0] Enable or disable colors. --coverage Generate code coverage report to file. --coverage-src Path to source code. -h | --help This help. ``` ### Health Score 77 — ExcellentBetter than 100% of packages Maintenance82 Actively maintained with recent releases Popularity66 Solid adoption and visibility Community58 Growing community involvement Maturity93 Battle-tested with a long release history Bus Factor1 Top contributor holds 67.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
