Behapi

======

Behat extension to help write describe features related to HTTP APIs.



PHP 7.3, Behat 3.7 and a discoverable php-http client are required to make

this extension work.



Installing this extension requires you to require `taluu/behapi` and an

implementation of a http client (providing

`psr/http-client-implementation ^1.0`,

`psr/http-factory-implementation ^1.0` and

`psr/http-message-implementation ^1.0`).



You can find some examples on the `examples/` directory.



Howto

-----

Add this in your behat.yml (it's for the `default` configuration but you can

use it for any configurations actually) :



```yaml

default:

  suites:

    main:

      paths: ['%paths.base%/features']

      services: '@Behapi\Container'

      autowire: true



      contexts:

        #- List

        #- your

        #- contexts

        #- here



        # examples :

        - Behapi\Http\RequestContext: ~

        - Behapi\Http\ResponseContext: ~



  extensions:

    Behapi\Behapi:

      base_url: 'http://localhost'

```



The `base_url` is the only requirement in the config for this extension to work.



There are other configurations keys, such as which formatter to use in a debug

environment, which headers you want to output in request or response while

debugging ; Use the `--config-reference` flag when invoking behat to have more

information on the available configuration.



After having installed the extension, you can then use the provided contexts

such as the `Behapi\Http\RequestContext` for the http api operations. In order

to use them, you need to use behapi's container (`@Behapi\Container`), or a

container capable of using behapi's container.



Some services are provided to be injected in contexts, which are the following:



- `@Http\Client\Common\PluginClientBuilder`, which will build a

  `Http\Client\Common\PluginClient` when needed

- `@Behapi\HttpHistory\History`, which is a sort of a container with the last

  requests done and last responses received

- `@Http\Message\MessageFactory`

- `@Http\Message\StreamFactory`



*Note:* You don't really need to bother with the services names, as they are

compatible with behat's auto-wiring feature.



In order to enable the Json assertions, you need to use the

`Behapi\Context\Json` context. Note that if you use the json context, you

should have used the client provided by the client builder used in the

`Behapi\Http\RequestContext` context.



If you need to play with the request being built, or the response created when

the request is sent, you need to inject the `@Behapi\HttpHistory\History`. It is

automatically reseted between scenarios (and scenarios outlines)



A documentation will be made (soon hopefully) with more details.



Contributing

------------

Contributing (issues, pull-requests) are of course always welcome ! Be sure to

respect the standards (such as psr-2, ... etc), follow proper git etiquette

(atomic commits, ...), proper conduct too and it should be fine !



Thanks

------

This extension was made while I was working at

[@Wisembly](https://github.com/Wisembly), and heavily used for writing our

features and integration tests. Special thanks goes to

[@lunika](https://github.com/lunika), [@rgazelot](https://github.com/rgazelot)

and [@krichprollsch](https://github.com/krichprollsch), who helped conceived

this extension, and also pushed me to open-source it.
