Why does this need to be a flag in the You can use https://github.com/nathany/looper to do this. |

Sure we can use a lot of tool to do that. |

There are a bunch of tools that do this. Doing it in cmd/go would require having fsnotify in the standard library, and we were unable to find a way to define that package portably. Let's keep using the existing tools (and maybe even rally around a single one, but outside the standard distribution). |

Currently, I use
go testIt's useful and work very well,but when I have developed. I must be to rerun the
go testcommand everytime is code changed. Especially when it is developed with TDD.I propose we increase the convenience and reduce the development time by adding the flag
-watchfor automatic reload to run the test when the file is changed.Example
Scenario I
go test -watchorgo test -watch .Scenario II
go test -watch ./...Both of them It's still the same behavior just add
-watchto reload and rungo testautomatically when file changed.I think it's a small change that comes along very handy.
And I would like to contribute development this one.
What do we think?
