Testing with Nette Tester
We use Nette Tester for unit testing. Test files should have .phpt extension.
shell
composer require nette/tester --dev
Basic Test Structure
php
<?php
declare(strict_types=1);
use Tester\Assert;
use Nette\Assets\SomeClass;
require __DIR__ . '/../bootstrap.php';
test('SomeClass correctly does something', function () {
$object = new SomeClass();
$result = $object->doSomething();
Assert::same('expected value', $result);
});
test('SomeClass handles edge case properly', function () {
$object = new SomeClass();
$result = $object->handleEdgeCase();
Assert::true($result);
});
Key points:
- Use the
test()function for each test case - The first parameter of
test()should be a clear description of what is being tested - Do not add comments before
test()calls - the description parameter serves this purpose - Group related tests in the same file
Testing Exceptions
To test if code correctly throws exceptions:
php
Assert::exception(
fn() => $mapper->getAsset('missing.txt'),
AssetNotFoundException::class,
"Asset file 'missing.txt' not found at path: %a%",
);
The Assert::exception() method:
- First parameter: A closure that should throw the exception
- Second parameter: Expected exception class
- Third parameter (optional): Expected exception message, can contain placeholders (%a% means any text)
If the entire test() block is to end with an exception, you can use testException():
php
testException('throws exception for invalid input', function () {
$mapper = new FilesystemMapper(__DIR__ . '/fixtures');<br>
$mapper->getAsset('missing.txt');
}, AssetNotFoundException::class, "Asset file 'missing.txt' not found at path: %a%");
