http-diff 0.0.4

http-diff

CLI tool to verify consistency across web server versions. Ideal for large-scale refactors, sanity tests and maintaining data integrity across versions.

Archives of precompiled binaries for http-diff are available for macOS and Linux on every release.

Dual-licensed under MIT or the UNLICENSE.

The tool works by looking at the configuration file that can be specified by --configuration argument.

http-diff --configuration=./configuration.json

• ./configuration.json - is the default value for this argument so it can be omitted.

Config example:

{
  "domains": ["http://domain-a.com", "http://stage.domain-a.com"],
  "endpoints": [
    {
      "endpoint": "/health"
    },
    {
      "endpoint": "/api/v1/users/<userId>"
    }
  ],
  "variables": {
    "userId": [123, 444]
  }
}

this config will be translated to following:

• GET request will be issued to http://domain-a.com/health and response be compared to response of GET http://stage.domain-a.com/health.

• Next endpoint /api/v1/users/<userId> has variable defined in it - <userId>. Anything within the brackets considered a variable name. In this case - userId. Variable then is looked up in the global variables property. In this case userId has two values: 123 and 444. This will be mapped to following requests:

  • GET http://domain-a.com/users/123 and compared with response from GET http://stage.domain-a.com/users/123.
  • GET http://domain-a.com/users/444 and compared with GET http://stage.domain-a.com/users/444.

All configuration options can be found here.
