Introduction

What is This?

In the development of the Open Grid Protocol and the PyOGP project, it became obvious that there were no canonical lists of use cases and things to test. This page is the first effort to remediate this omission. While we don't go as far as providing use cases here, we do list common functionality and interoperability tests.

About the OGP Test Cases

The objective of the Open Grid Protocol is to specify syntax and semantics of SL Grid messages to the degree that interoperable viewers, agent domains, region domains and regions may be coded without resort to close examination of open source code from Linden Lab or peeking into the interaction between running clients and servers. The Second Life Grid has been developed sufficiently, the reasoning goes, that it should be possible to shine the bright light of inquiry on the process and document the living heck out of how the system works. Moving forward we should see advantages as software developers code to documented requirements and standards. The "OGP Test Cases" are a catalog of tests that demonstrate compatibility with the written spec.

Well... that's how it's supposed to be... In the real world, "running code" trumps written specifications, and probably will continue to do so. And that's one of the reasons we have the interop tests; properly written test cases succinctly communicate abstractions introduced in written specifications. So rather than viewing the SLGOGP spec and these tests as separate, think of them as being two sections of the same document.

Base Tests ( Test 0.* )

Many OGP messages take the form of an LLSD message serialized to XML and POSTed to an URL somewhere via HTTP (or HTTPS.) In the ideal world, HTTP would be free from error. But as it turns out there are many ways in which a HTTP request could fail, especially if your implementation of OGP uses proxies, load balancers, n-tier service architectures, etc. These tests are intended to ensure your client library properly communicates HTTP errors, assuming your client library has a standard technique for handling and recovering from such errors.

It is entirely possible that your client library does not handle such errors cleanly. This is not a failure, per se, but we strongly encourage implementers to expose an interface to client applications allowing exceptional events to be communicated through the client library and to the application.

Base Test 0.0 - Return an Exception when Accessing a Non-Existent Resource

This test simply posts a properly formatted login request to an URL that does not exist. We anticipate a HTTP 404 result code, or at least that's what we would return if you sent a request to an undefined URL. In an ideal world we would test a resource from each resource class to ensure client library code handling each message properly propagates the "Not Found" exception. However, in the interests of alacrity we're only describing this test in terms of the agent_login resource class.

So, test 0.0 is considered "successful" if after attempting to access the agent_login resource defined for fixture 1.0 (Arthur Crimthande) at the agent domain described in fixture 0.404 (the canonical undefined agent domain), the client library produces a "HTTP Not Found" exception.

Base Test 0.1 - Return an Exception when Accessing a "Broken" Resource

This test posts a properly formatted login request to an URL that has been preconfigured to return a HTTP 500 result code.

So, test 0.1 is considered "successful" if after attempting to access the agent_login resource defined for fixture 1.0 (Arthur Crimthande) at the agent domain described in fixture 0.500 (the canonical broken agent domain), the client library produces a "HTTP Internal Server Error" exception.

Base Test 0.2 - Return an Exception when Accessing an "Unavailable" Resource

This test posts a properly formatted login request to an URL that has been preconfigured to return a HTTP 503 result code.

So, test 0.2 is considered "successful" if after attempting to access the agent_login resource defined for fixture 1.0 (Arthur Crimthande) at the agent domain described in fixture 0.503 (the canonical unavailable agent domain), the client library produces a "HTTP Service Not Available" exception.

LLSD Tests ( Test 1.* )

These tests exercise concepts introduced in the "LLSD" section of the OGP spec.

LLSD Test 1.0 - Return an Exception when Accessing a Resource with the Wrong HTTP Method

If an agent domain, region domain or region receives a resource request using an unsupported HTTP method, the resource SHOULD respond with a HTTP 405 result code.

Test 1.0 is considered "successful" if, after attempting sending a HTTP GET to the authentication URL defined in fixture 0.200 (a working agent domain), the client library produces a "LLSD Method Not Allowed" exception.

LLSD Test 1.1 - Return an Exception when Accessing a Resource via GET with an Improper Media Type in Accept

If an agent domain, region domain or region receives a resource request via a HTTP GET, and the requester uses the 'Accept:' header to specify the media type it will accept, and that media type is not supported by the resource, the resource SHOULD respond with a HTTP 415 result code.

hmm... need to define a canonical resource that accepts GET.

LLSD Test 1.2 - Return an Exception when Accessing a Resource via POST with an Improper Media Type in Accept Header

If an agent domain, region domain or region receives a resource request via a HTTP POST, and the requester uses the 'Accept:' header to specify the media type it will accept, and that media type is not supported by the resource, the resource SHOULD respond with a HTTP 415 result code.

Test 1.2 is considered "successful" if, after POSTing the following message body to the authentication URL defined in fixture 0.200 (a working agent domain) with the 'Content-Type:' header set to 'application/llsd+xml' and the 'Accept:' header is set to 'application/llsd+foo', the client library produces a "LLSD Unsupported Media Type" exception.

LLSD Test 1.3 - Return an Exception when Accessing a Resource via POST with an Improper Media Type in Content-Type Header

If an agent domain, region domain or region receives a resource request via a HTTP POST, and the requester uses the 'Content-Type:' header to identify the media type of the the request body, and that media type is not supported by the resource, the resource SHOULD respond with a HTTP 415 result code.

Test 1.3 is considered "successful" if, after POSTing the following message body to the authentication URL defined in fixture 0.200 (a working agent domain) with the 'Content-Type:' header set to 'application/llsd+foo', the client library produces a "LLSD Unsupported Media Type" exception.

LLSD Test 1.4 - Return an Exception when POSTing bad XML to a Resource

If an agent domain, region domain or region receives a resource request via a HTTP POST, and Content-Type header of the request describes the body of the request as being a 'application/llsd+xml' media type, and the body is improperly formed XML, the resource SHOULD respond with a HTTP 400 result code.

Test 1.4 is considered "successful" if, after POSTing the following message body to the authentication URL defined in fixture 0.200 (a working agent domain) with the 'Content-Type:' header set to 'application/llsd+xml', the client library produces a "LLSD Bad Request" exception.

      </map>
    </map>
  </map>

LLSD Test 1.5 - Return an Exception when POSTing a misshaped request to a Resource

If an agent domain, region domain or region receives a resource request via a HTTP POST, and the requester uses the 'Content-Type:' header to identify the media type of the the request body, and request is "mis-shaped" with respect to the LLIDL definition of the resource, it (the resource) SHOULD respond with a HTTP 400 result code.

Test 1.5 is considered "successful" if, after POSTing the following message body to the authentication URL defined in fixture 0.200 (a working agent domain) with the 'Content-Type:' header set to 'application/llsd+xml', the client library produces a "LLSD Bad Request" exception.

<?xml version="1.0"?>
