Description

Improve Test Server usability improvements and bugs

Core objectives

Test Server provides a simplified fast im-memory implementation of Temporal Server API with additional features provided for testing only like time-skipping. This Epic tracks the tasks related to the improvement of the Test Server itself that don't affect Java SDK.

Tasks

• Issue with TestWorkflowEnvironment and ParentClosePolicy #1079
• Add ResetWorkflowExecution support in Test Server #1093
• TestWorkflowEnvironment schedules the first activity retry immediately #1069
• TestWorkflowService: Make tokens unique across retries #84
• TestWorkflowEnvironment - add support for filtering for ListOpenWorkflowExecutions #1139
• Implement temporal.api.workflowservice.v1.WorkflowService/DescribeNamespace in test-server #1158
• Test Server fails when starting a workflow that already exists. #1220
• Test Server does not populate WorkflowExecutionStartedEventAttributes.FirstExecutionRunId in the history. #1221
• Test server generates the same activity task token on retry #1223
• TestWorkflowEnvironment: Set close time on the visibility record #262
• Test Server should add warning logging if no workers listen on a task queue with tasks #1403
• Add history pagination to Test Server #1642
• Add support for TerminateIfRunning WorkflowIdReusePolicy in Test Server #1682
• Add capability and SDK metadata field for test server #1746
• Add support for workflow update to Test Server #1742
• Implement workflow_start_delay in test server #1692
• Support listWorkflowExecutions in test server #1693

Bugs

• Workflow execution with Workflow.await(condition) times out in unit tests with enabled time skipping #1291
• Test Server is unstable for child workflows reporting completion fast #1288
• Fix test server publishing the Completion of child workflows before the Start sometimes #1289
• TestServer erroneously propagates timeouts of the parent workflow to the child  #1319
• Align Test Server behavior with the real one if WorkflowExecutionCompleted is not the last command #1398
• Test Server doesn't reset sticky queue if timeout fired for an outdated workflow task #1401
• Test server does not decrement time skipping lock for outstanding activities on workflow completion #1138
• Test server should not require task queue on continue as new #1424
• Test server not populating DescribeWorkflowExecutionResponse.workflow_execution_info.task_queue #1425
• Test server timeouts improperly set to 10 years when not user set #1426
• Test server heartbeat timeout issue #1427
• Test server does not error on already-started child workflow #1429
• Test server with child workflow and signal is timing out when attemping unlock-with-sleep #1618
• Test Server hanging or reporting completed on start update requests #1903

Edited description to remove temporalio/sdk-core#426, but it also qualified the names of all issues too, sorry!
