Description

As a Beam Playground user, I want to get execution output for the specific Python example code that I run in Beam Playground

Acceptance criteria:

1. Beam Python example code executed on the backend
2. Output received by the frontend
3. Compilation failures are caught and redirected to the frontend app
4. Runtime failures are caught and redirected to the frontend app

 

Scenario: Python example code running

Given: User ran valid Apache Beam Python example code in Beam Playground

When: Backend accepts the gRPC request

Then: Backend apply preparation steps for Python SDK

AND: Backend apply validation steps for Python SDK

AND: Backend runs a new background process using the Python console command to run python file with code snippet

 

 

 __ 

Given: Backend ran a new background process using the Python console command to Run code snippet

When: Validation is completed

AND: Preparation is completed

And: Executable file located in local FS

Then: Backend app runs executable file using Python console command in background task

 __ 

Given: Backend app runs executable file using Python console command

When: Code executed completely

And: Stdout and stderr outputs located at local fs

Then: Backend reads the stdout and sends its content to the frontend with complete message code

 __ 

Given: Backend app runs executable file using Python console command

When: Code executed with error

And: Stdout and stderr outputs located at local fs

Then: Backend reads the stderr and sends its content to the frontend with an error message code

 __ 

Given: Backend app runs executable file using Python console command

When: Execution is finished with any code

And: Backend sent a response to frontend

Then: Backend clean-ups build and runtime artifacts.
