Can you iterate over clusters instead of picking up the first?

Changed the code to iterate through the cluster.

can you move out these long responses to a separate file, so that tests are more maintainable? see https://github.com/databrickslabs/ucx/blob/main/tests/unit/assessment/__init__.py

    ws.cluster_policies.get = _cluster_policy
+    ws.pipelines.get().spec.clusters = _load_list(PipelineCluster, f"clusters/{pipeline_cluster}")


this is silly and makes no sense at all. mock the entire response, not just a subset - ws.pipelines.get.return_value = _load_list(...

Now capturing the entire PipelineResponse instead of only mocking the cluster part.

-def workspace_client_mock(clusters="no-spark-conf.json"):
+def workspace_client_mock(clusters="no-spark-conf.json", pipeline_cluster="pipeline_cluster.json"):


this makes no sense - you're not mocking the list response. in this case - argument is not required.

Was are having this parameter to give an option to specify the pipeline cluster json. Removed this argument now.

nfx

do you read the surrounding code before making changes?...

nfx · 2024-02-07T19:04:53Z

tests/unit/assessment/__init__.py

    ws = create_autospec(WorkspaceClient)
    ws.clusters.list.return_value = _load_list(ClusterDetails, f"../assessment/clusters/{clusters}")
    ws.cluster_policies.get = _cluster_policy
+    ws.pipelines.get.return_value = _load_list(GetPipelineResponse, "clusters/pipeline_cluster.json")[0]


@prajin-29 , do you read the surrounding code before changing it? 🤦

why ws.pipelines.get is different than ws.cluster_policies.get? it's illogical!

updated ws.peipeline.get similar to ws.cluster_policies.get . With this I have included the pipeline spec configuration also inside the json so that we can access everything in one shot.

nfx

Test implementation is incorrect and confusing

nfx · 2024-02-08T09:33:57Z

tests/unit/assessment/__init__.py



+def _pipeline_cluster(pipeline_id: str):
+    pipeline_response = _load_list(GetPipelineResponse, f"clusters/{pipeline_id}.json")[0]


Why is it load_list and not load fixture? Why do you put pipeline test fixtures to a clusters folder? This will confuse people after you

@nfx now the code is rebased with the main and using the pipeline test fixture from the pipeline folder.

-    }
-    ws.pipelines.get().spec.configuration = config_dict
+    ws = workspace_client_mock(clusters="job-source-cluster.json")


@prajin-29 I've extended workspace_client_mock in #923 to read pipeline spec from a json file in under tests/unit/assessment/pipelines, so you can rebase your code off of that.

Rebased the code to use the change

+    ws.workspace.export().content = "JXNoCmVjaG8gIj0="
+    ws.dbfs.read().data = "JXNoCmVjaG8gIj0="


do we need these for pipeline tests?

Yup I added this to cover the negative scenario for full coverage. But with the addition of the spec in json we can remove this. Removed this from test.
