gomparator

gomparator compares HTTP GET JSON responses from different hosts by checking if they respond with the same json (deep equal ignoring order) and status code.

Download and install

go get -u github.com/emacampolo/gomparator

Create a file with relative URL

eg:

/v1/payment_methods?client.id=1
/v1/payment_methods?client.id=2

Run

$ gomparator --path "/path/to/file/with/urls" --host "http://host1.com" --host "http://host2.com" -H "X-Auth-Token: abc"

By Default, it will use 1 worker, and the rate limit will be 5 req/s
