A middleware for gor to verify against regressions on your acc environment

Gor tester

A gor middleware app that allows you to verify if your acc server is sending (more or less) the same responses as your prod server.

(last tested with gor 1.0.0)

getting up and running

Build it with

mvn package

Run it with

gor --input-raw <your-prod-server> --output-http=<your-staging-server> --middleware "./target/appassembler/bin/gor-tester default_config.yml" --input-raw-track-response

What does it do?

gor will send each request that was sent to the production server to your staging server. This middleware will compare the response from the acceptation server to that of the production server.

The middleware allows you to write rules that

• prevent certain requests from being replicated to the auth server
• modify the replay request. To replace auth headers for example.
• modify the original or replay response.
  • To unchunk the response.
  • To unzip the response so that they can be better compared.

The middleware also allows you to write rules that

• Check if the replayed response contains all the headers of the original response and possibly more
• Check if the status codes match
• Check if the bodies are exactly equal

Gor sends the requests and responses in an undefined order to the middleware, but your rule's methods will always be called with the data you need (the middleware stores data if needed and waits for the rest to arrive).

How do I use it?

A few rules are provided. You configure them in a yaml file. There is a good chance that the provided rules are not enough and you'll have to add some rules of yourself.
