             Summary: Expose a resolver in the SPI to lookup the deploymentUrl easily from an extension
                 Key: ARQ-1205
                 URL: https://issues.jboss.org/browse/ARQ-1205
             Project: Arquillian
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Base Implementation
    Affects Versions: 1.0.3.Final
            Reporter: Dan Allen
            Priority: Minor


Story:

*In order* to initialize clients to conveniently access URLs in the deployed application
*As an* extension writer
*I want* to be able to use an SPI to calculate the deployment URL (consistent with the [URLResourceProvider|http://docs.jboss.org/arquillian/aggregate/1.0.3.Final/org/jboss/arquillian/container/test/impl/enricher/resource/URLResourceProvider.html])

Scenarios:

*Given* that I need to access the deployment URL from an extension
*When* I invoke a public SPI method that resolves the deployment URL
: *And* the test case only has one deployment
*Then* the SPI method should return the URL to that deployment

*Given* that I need to access the deployment URL from an extension
*When* I invoke a public SPI method that resolves the deployment URL
: *And* the test case has multiple deployments
: *And* I specify a string-based deployment name as an argument
*Then* the SPI method should return the URL to that deployment

Rationale:

Extensions may need access to the deploymentUrl for setting up resources, such as a client. However, there is quite a bit of logic necessary to resolve the deploymentUrl properly, especially when multiple deployments are in use.

Therefore, I propose adding an SPI that exposes the logic in the URLResourceProvider. Here's a rough sketch of the SPI:

{code}
public interface DeploymentURLResolver {
    public URL resolveURL();

    public URL resolveURL(String deploymentName);
}
{code}
