Goad was our entry in this year's Gopher Gala and was built in under 48 hours by a team of 4.

Any plans to include a way to "script" the urls, types of requests, etc?

Load testing is more than hammering a single URL thousands of times.

jcxplorer3• 10 years ago

Definitely! Not something we could have done properly in 48 hours though :)

Take a look at the work by https://stormforger.com/

They offer a ruby DSL last time I checked.

Seconded. Load testing tools seem to either be the "hammer with a single, anonymous GET request" or jMeter which is capable of anything but painful to work with. There are some other tools out there but the lack of documentation makes it hard to tell what you can and can't do.

The idea is interesting, but I wonder how this isn't very expensive to run...

jcxplorer3• 10 years ago

A test that would use 100 lambda functions in parallel from each of the 4 regions and run for 5 minutes would cost about 3 USD. That should achieve a concurrency level of 100,000. That would be the most expensive test possible at the moment. Smaller tests are basically free.

Actually not that bad... Great.

Why it is limited to 100,000 concurrent request ?

Not to rain on anyone's parade but you could generate A LOT more load using regular old EC2 instances if all you had was $3...

Pretty cool.

I wish Lambda supported Go natively, the node.js wrapper hack to invoke the binary and proxy the stdin/out is really dumb.

Drat. "Goad" -- as in the "prod" or "poke" sense of the word -- has been my defacto default name for the inevitable build script in my golang projects (once I grow out of the single-word `go` tool commands). I'll have to rename if this catches on :D
