how to test swift api in transient mode
Hi,
I'm trying to migrate my code to use jclouds 2.0.0. I changed from swift
dependency to openstack-swift, so I use SwiftApi object to access Swift
(instead of BlobStore which I used before). The code seems to look fine
when I run it on a live cluster.
But I had unit tests that were using transient mode/container and now I
cannot make them work.
I got:
com.google.inject.ConfigurationException: Guice configuration errors:
1) No implementation for org.jclouds.openstack.swift.v1.SwiftApi was bound.
while locating org.jclouds.openstack.swift.v1.SwiftApi
Is transient mode still valid in 2.0? It is listed as possible
"providerOrApi" in
org.jclouds.ContextBuilder#newBuilder(java.lang.String). How to use it?
There is no information about it on documentation pages, wheras it still
claims that " Write your unit tests without mocking complexity or the
brittleness of remote connections. Writing tests for cloud endpoints is
difficult. jclouds provides you with Stub connections that simulate a
cloud without creating network connections." (from
http://jclouds.apache.org/start/what-is-jclouds/)
Thank you in advance,
Aleksandra

You can't create a SwiftApi view of a transient blobstore; instead you
must use the portable BlobStore view:
String provider = ...; // openstack-swift or transient
BlobStoreContext context = ContextBuilder.newBuilder(provider)
.endpoint(endpoint)
.credentials(user, password)
.buildApi(BlobStoreContext.class);
BlobStore blobStore = context.getBlobStore();
// interact with blobStore, e.g., get, put
...
context.close();

I had to switch (or I thought that I had to) because I wanted JClouds to
take care of repeating PUT operations after a failure. And for now it
looks like it helped for this issue.
However, I would like to have junit test for this code.
Before I used the same code but with "transient" as a provider.
Now after changing dependency version to 2.0.0 it unit tests trow:
com.google.inject.ConfigurationException: Guice configuration errors:
1) No implementation for org.jclouds.openstack.swift.v1.SwiftApi was bound.
while locating org.jclouds.openstack.swift.v1.SwiftApi
The same piece of code works perfectly when run with a live swift
instance and "openstack-swift" as provider.
Best,
Aleksandra

Aleksandra, you can use both openstack-swift and transient APIs via the
BlobStore interface. You should only need to change the provider name
from swift to openstack-swift.
