gta

gotta test 'em all!

gta is a tool that helps you check your Go project against various versions of its dependencies. This includes optionally running a command, like go test, against each combination. So it's kinda like git-bisect, but for your deps.

gta is gps-based, and should interoperate with several different Go package managers (gb, godep, gom, gpm, and glide, though glide is likely to work best). When available, gta reads the lock file from that tool, and tries to hold constant all the versions listed there, varying only the versions of the dependency you name.

In general, gta is probably most useful for exploring a semver range you've already set in a manifest, or for simply exploring all the possible versions of a particular dependency.

Installation

$ go get github.com/sdboyer/gta

Usage

# For now, gta must be run from a project root
$ cd $GOPATH/src/github.com/me/myproject
# Just look for valid dependency solutions for each version of the dep
$ gta github.com/somedep/tocheckitsversions
# Or, also run "go test" against each version where there's a solution
$ gta -r "go test" github.com/somedep/tocheckitsversions

See gta --help for more information.

Caveats

• This is very alpha - "release early, release often" - and while it has worked at least once, it will likely break :) Please file issues!
• The format of gta's glide.yaml file is not one your standard version of glide can read, so don't bother trying (it's based on the PR to integrate gps into glide)
