digitalmars.D.learn - how to use dub to run all / chosen dependency lib's unittests

reply mw <mingwu gmail.com> writes:
Hi,

I'm using dub.json to specify the dependencies libs for my 
project.

I'm just wondering how I can use dub to run all the tests of 
those dependencies libs (of the transitive closure of *all* the 
libs) to make sure my project is built on a very solid foundation?

I know this could be very time-consuming, probably will run it 
over-night.

On the other hand, what's the command to run dub test on a single 
dependency lib?


Thanks.

I don't see any specific command to do it in dub itself.

I've recently discovered that `dub describe` gives you the directories 
of all your dependencies in a JSON format.

I used this to write an install script for dependent library artifacts. 
See 
[here](https://github.com/schveiguy/raylib-d/blob/master/install/source/app.d).

It would be pretty easy to do the same thing to run dependency unit 
tests. e.g. something like `foreach(dir; getDubDependencyDirectories) { 
cd(dir); execute("dub", "test"); }`

You'd have to write getDubDependencyDirectories. But it's just parsing JSON.

Thanks. Maybe Python is easier for such glue code.


BTW, does any of the unit test library can do what I want? E.g.
