Baton

Baton is a load testing tool written in Go. It currently supports GET, POST, PUT, and DELETE requests.

Install Baton

Installation of Baton with Go is as easy as running go get.

$ go get -u github.com/americanexpress/baton

Binary releases are available.

Using Baton

Baton currently supports the following options:

  -b string
        Body (use instead of -f)
  -c int
        Number of concurrent requests (default 1)
  -f string
        File path to file to be used as the body (use instead of -b)
  -i    Ignore TLS/SSL certificate validation
  -m string
        HTTP Method (GET,POST,PUT,DELETE) (default "GET")
  -o    Supress output, no results will be printed to stdout
  -r int
        Number of requests (use instead of -t) (default 1)
  -t int
        Duration of testing in seconds (use instead of -r)
  -u string
        URL to run against
  -w int
        Number of seconds to wait before running test
  -z string
        Read requests from a file

Below is A basic example which will use 10 workers to send 200,000 requests is as follows:

$ baton -u http://localhost:8080/test -c 10 -r 200000

Instead of the number of requests, you can specify the time (in seconds) during which the requests should be sent. Baton will wait for all the responses to be received before reporting the results.

Requests file

When specifying a file to load requests from (-z filename), the file should be of CSV format (RFC-4180)

<method>,<url>,[<body>],[<header-key>:<header-value>, ...]
...

You can have one or more headers at the end separated by ,

For example:

POST,http://localhost:8888,body,Accept: application/xml,Content-type: Secret
GET,http://localhost:8888,,,

Example Output:

Features which are on the horizon...

Dynamic generation of data based on a template
Testing REST endpoints with dynamically generated keys

Caveats

Statistics are only provided when a fixed number of requests is provided (instead of providing a duration).
