Lawman - Your Architectural Enforcer for SaloonPHP

A PestPHP Plugin for SaloonPHP that helps you enforce architectural rules with your API integrations.

Introduction

Lawman is a PestPHP Plugin for SaloonPHP which allows you to easily write architecture tests for your API integrations with a focus on them being easy to write and easy to read. After all, if SaloonPHP makes our API integrations beautiful, the tests for them should be beautiful too, right?

Lawman makes testing your SaloonPHP API integrations, from an architecture point of view, much easier to do. Allowing you to see, at a glance, what a test is actually doing. Lawman is a plugin for PestPHP meaning you can use Lawman Expectations and PestPHP Expectations together, just chain whatever you need for your tests!

Examples

Let's take a look at how Lawman can help make writing tests easier.

Let's say we have a Connector class that we want to test, with PestPHP we could do the following:

test('connector')
    ->expect('App\Http\Integrations\Integration\Connector')
    ->toExtend('Saloon\Http\Connector')
    ->toUse('Saloon\Traits\Plugins\AcceptsJson')
    ->toUse('Saloon\Traits\Plugins\AlwaysThrowOnErrors');

So that test is ensuring our class extends the base Connector and uses the AcceptJson and AlwaysThrowOnErrors traits. Whilst that test works, we could perhaps make it quicker to write and easier to read, so with Lawman, you can do:

test('connector')
    ->expect('App\Http\Integrations\Integration\Connector')
    ->toBeSaloonConnector()
    ->toUseAcceptsJsonTrait()
    ->toUseAlwaysThrowOnErrorsTrait();

Next up, let's take a Request test that we have:

test('request')
    ->expect('App\Http\Integrations\Integration\Requests\Request')
    ->toExtend('\Saloon\Http\Request')
    ->toImplement('Saloon\Contracts\Body\HasBody')
    ->toUse('Saloon\Traits\Body\HasFormBody')
    ->toUse('Saloon\Traits\Plugins\AcceptsJson');

Lawman makes this test much nicer to read:

test('request')
    ->expect('App\Http\Integrations\Integration\Requests\Request')
    ->toBeSaloonRequest()
    ->toSendPostRequest()
    ->toHaveFormBody()
    ->toUseAcceptsJsonTrait();

What about if we want to test our Connector has an Authentication method? Lawman makes this easy to do, it even works with multi auth:

test('connector')
    ->expect('App\Http\Integrations\Integration\Connector')
    ->toBeSaloonConnector()
    ->toUseCertificateAuthentication()
    ->toUseTokenAuthentication();

Lawman also has Expectations for the Pagination, Cache and Rate Limit Plugins:

test('request')
    ->expect('App\Http\Integrations\Integration\Requests\Request')
    ->toBeSaloonRequest()
    ->toSendPostRequest()
    ->toUsePagedPagination()
    ->toHaveCaching()
    ->toHaveRateLimits()

Maybe our Connector has some Retry instructions that we want to test. Again, with Lawman, it's as simple as:

test('connector')
    ->expect('App\Http\Integrations\Integration\Connector')
    ->toBeSaloonConnector()
    ->toBeTriedAgainOnFailure()
    ->toHaveRetryInterval()
    ->toUseExponentialBackoff()
