th2 act template (3.9.0)

Overview

Act is a passive th2 component with parameterized functions which is implemented as part of the test logic. Script or other components can call these functions via gRPC. Act can interact with conn (Connects), hands, check1s, other acts to execute its tasks. Information about the progress of the task is published to the estore th2 component via MQ pin. This th2 component type allows frequently used script logic into it and then share it between all th2 components.

This project is implemented gRPC API described in the th2-grpc-act-template

Most of them consists of the next steps:

  1. Gets a gRPC request with parameters.
  2. Requests checkpoint from check1 via gRPC pin
  3. Sends the passed business message to Connect via mq pin
  4. Waits the specific business message from Connect during specified timeout
  5. Returns responded business message with checkpoint

Descriptor gradle plugin

Also we recommend to apply th2-box-descriptor-generator plugin. It allows generating a th2 descriptor. CI should publish the project's docker image with the descriptor content as the value of the protobuf-description-base64 label. Such descriptors can be used to interact with a box-raised gRPC server.
