Unit test of POST request uses body format

[netsensei]

The POST request test uses the old JSON body format to push a record to the Datahub. Like this:

list($crawler, $response, $data) = $this->apiRequest('POST', '/v1/data', [
    'format' => $dataConverterId,
    'data'   => $testData,
]);

Later on, we decided to abandon this approach and go for a new way of POST'ing data to the API:

• The body would contain the entire un-encapsulated record. Serialised in a target format (LIDO, MARC,...)
• The type of data is defined in an HTTP request header.
• The datahub configuration has a parameter which data is accepted.

TODO

• The unit test for the POST reuqest should be adapted to reflect the new changes
• The apiRequest() method in OAuthTestCase currently only allows for posting JSON data and needs to be expanded / adapted.

This issue was fixed in development sprint May / June 2017. Closing.

The HTTP request now expects a valid XML document as raw body and a Content-Type: application/lido+xml HTTP request header.
