Problem:
Samza today provides various configurations like Samza-Yarn, Samza as a library and in coming future Samza will support In-memory system, that a user can produce/conusme from. With 0.13 release Samza provide a high level fluent api for chaning complex jobs, but still Samza users have to get their hands dirty with too much configuration details and dependency on external system(like kafka) to write integration tests. In order to alleviate this we intend to provide a fluent test api to users. This will help in setting-up quick tests against their system without depending on underlying incoming stream from a Kafka Topic. The goal of the proposed SEP we will provide a standardized framework to set-up continuous integration test for High Level Api, Low Level Api in any configuration of Samza with ease. Users won’t have to worry about the underlying Samza config details or even understand low level implementation. This abstraction will increase developer productivity and help them make their Samza system robust.
Motivation
Addition of this Continuous Integration Test Framework will alleviate:
Lack of a standardized way to set up integration tests for users
Lack of brevity in code and understanding low level config details of the Samza Api to set up samza systems
Lack of a pluggable Test System with any Samza configuration
Set of robust tests for current samza api
