A library for testing web APIs with PHPUnit.

Getting Started

Requirements/dependencies

This requirement could potentially be relaxed to older version of PHP upon request.

Installation

Git

git clone https://github.com/jamesjohnmcguire/ApiTest

Composer

composer require --dev https://packagist.org/packages/digitalzenworks/api-test

Usage:

API Testing

There is one main class with one main method. You can call it like this:

require_once 'vendor/autoload.php';

use DigitalZenWorks\ApiTest\ApiTester;

final class UnitTests extends TestCase
{
    #[Test]
    public function ApiEndPointPostSuccess()
    {
        $data =
        [
            'name' => 'Somebody',
            'email' => 'Somebody@example.com'
        ];

        $apiTester = new APITester('https://httpbin.org');
        $testOptions = new TestOptions();
        $testOptions->tryBasicAsserts = false;

        $response =
            $this->apiTester->apiEndPointTest(
                'POST', 'https://httpbin.org/post', $data, $testOptions);

        $this->assertIsArray($response);
    }
)

The apiEndPointTest parameters are:

Parameter Type Parameter
method string The HTTP method to use.
endPoint string The API end point.
data ?string The request data.
testOptions TestOptions A set of options.
Refer to TestOptions for details.

TestOptions is an object with the following properties:

Property Default Description
contentRequired true Indicates whether
content is required
in the response
body.
errorExpected false Indicates whether an
error is expected.
guzzleAdditionalOptions null Additional Guzzle
options to be
included.
requestDataType null The data type for
the request. Can be
one of the following
values: 'body',
'form_params',
'json' or
'multipart'.
tryBasicAsserts true Indicates whether
included basic
assertions should be
tried.
userAgent The user agent to
include in
the headers.

Page or End-to-End Testing

This also supports testing HTML pages directly. You can call it like this:

require_once 'vendor/autoload.php';

use DigitalZenWorks\ApiTest\PageTester;

final class UnitTests extends TestCase
{
    #[Test]
    public function SimplePage()
    {
        PageTester $pageTester =
            new PageTester('https://httpbin.org', 'text/html', 'text/html');

        $endPoint = 'https://httpbin.org/get';

        $content = $pageTester->webPageTest('GET', $endPoint, null);

        $this->assertNotNull($content);
        $this->assertNotEmpty($content);
        $this->assertStringContainsStringIgnoringCase(
            '<!DOCTYPE html>', $content);
    }
}

Additional Examples

You can refer to the unit tests for additional example usage.

Additional Notes

This uses Guzzle to process the API request.

Guzzle Response Object

You can access the Guzzle response object by accessing the public $response property of PageTester. like:

    $response = $pageTester->response;
    $status = $response->getStatusCode();
    $this->assertEquals(200, $status);

Note: Status is already checked within TestSitePage. It's just included here for the purposes of example.

Guzzle History Object

You can also access the Guzzle history (handler) object by accessing the public $response property of PageTester. like:

    $history = $pageTester->history;
    $redirects = count($history) - 1;
    $this->assertEquals(1, $redirects);

This can be useful for tracking redirects, among other things.

Details on tryBasicAsserts

If tryBasicAsserts is true, several basic assertions will be performed based on the provided options and response. Below is a summary of the assertions, their purposes, and the conditions under which they are applied.

Assertion Description Condition
assertNotEmpty($body) Verifies that the content body is not empty. Checked if $contentRequired is true.
assertJson($body) Validates that the content body is valid JSON. Checked if $jsonRequired is true.
assertEquals(200, $status) Ensures the HTTP status code is 200 (OK). Checked if $errorExpected is false.
assertNotEquals(200, $status) Ensures the HTTP status code is not 200. Checked if $errorExpected is true.
assertArrayHasKey('error', $data) Checks if the error key exists in the data array. Checked if $errorExpected is true.
assertArrayNotHasKey('error', $data) Checks if the error key does not exist in the data array. Checked if $errorExpected is false.
assertTrue($errorExpected) Verifies that $errorExpected is true. Checked during exception handling.
