To test file uploads and downloads in PHPUnit, you can follow these steps:
Install the Guzzle HTTP client library, which provides a convenient way to send HTTP requests and handle file uploads and downloads:
composer require guzzlehttp/guzzle --dev
Create a new test case class that extends PHPUnit\Framework\TestCase:
use PHPUnit\Framework\TestCase;
class FileUploadDownloadTest extends TestCase
{
// ...
}
Implement a test for file uploads. This can be done by sending a multipart/form-data POST request with a file attachment:
public function testFileUpload()
{
$client = new \GuzzleHttp\Client();
$response = $client->request('POST', 'http://example.com/upload', [
'multipart' => [
[
'name' => 'file',
'contents' => fopen('/path/to/file', 'r'),
],
],
]);
$this->assertEquals(200, $response->getStatusCode());
// Perform additional assertions on the uploaded file if needed
}
Implement a test for file downloads. This can be done by sending a GET request to the file URL, and then saving the response body to a file:
public function testFileDownload()
{
$client = new \GuzzleHttp\Client();
$response = $client->request('GET', 'http://example.com/download/file', [
'sink' => '/path/to/save/file',
]);
$this->assertEquals(200, $response->getStatusCode());
// Perform additional assertions on the downloaded file if needed
}
Run the PHPUnit tests and verify that the file uploads and downloads are working as expected:
./vendor/bin/phpunit
By following these steps, you can effectively test file uploads and downloads in PHPUnit using the Guzzle HTTP client library.
