Readme
ngb is a commandline utility for testing and benchmarking a list of URLs. It is similar to Apache Bench, but can also perform additional checks on the content returned from the server.
ngb runs iterations of tests against a list of URLs, where each URL is a separate test. Every iteration runs all the test URLs before continuing to the next iteration.
Once all requests are executed for a test, the next test is executed (the next URL). Once all tests are finished, the next iteration is executed.
You can specify the total number of requests per test, with the number of concurrent requests to use.
ngb by default checks that the content returned from the server is the same in all responses, and will report an error for responses that do not match the baseline response. The baseline response is the first response returned from the server.
ngb reports at the end of every test the average request duration, and details all the errors if there were any.
npm install -g ngb
> ngb
Usage: ngb [OPTIONS] URL [URL...]
URL A URL to perform a test against
Options:
-m <method> the http method to use for the request. default is GET.
-i <number> the number of iteration to run all the tests. default is 1.
-d <number> delay in seconds between test iterations. default is 30.
-c <number> concurrent requests per test per iteration. default is 1.
-n <number> total number of requests per test per iteration. default is 1.
-t <number> request timeout in milliseconds to consider as an error. default is 10000
-p <url> proxy as http[s]://[username:password]@hostname_or_ip[:port]. default is no proxy
--content <file or string> the request content to send to the server. may be a string to send or a js file that exports a function that will be used to return the content
--content-type <type> the content type that is sent to the server. default is application/json
--check-content <true|false> whether to check the response body and report an error for responses that do not match the expected content. default is true.
--ntlm <domain> NTLM domain if the proxy auth is ntlm
