Include multiple paths

[bblack]

While we can exclude multiple paths, we can't include multiple paths since the root option is only a single path. Would like to be able to include multiple paths.

can you please give me an use case so I can understand how it would work?

[bblack]

I have a project rooted at ., and two directories I'd like to test, ./app and ./lib.

Presently, I can specify root: './app' or root: './lib' but not both.

well, istanbul expects exactly one root. the root only means that the report will follow subfolders from that point. you may want to create 2 mocha_istanbul tasks, like

mocha_istanbul:{
  app: { 
    options: { 
       root: './app'
    }
  },
  lib: {
    options:{
     root: './lib'
    }
  }
}

the src is where it expect more than 1 folder, but I'm not aware of the consequences of doing this:

mocha_istanbul:{
  app: { 
    src: ['./app','./lib'],
    options: { 
       root: './app'
    }
  },
}

Closing this for now, if needed reopen

Hello, I have a question regarding combining tasks result into one report and I think it is linked to the question here,
You describe a task for ./app and ./lib in your example, how would you get a report combining the results from several task like this?

I see in the standard example you use the coverageFolder attribute like so:

istanbul_check_coverage: {
default: {
options: {
coverageFolder: 'coverage*', // will check both coverage folders and merge the coverage results
check: {
lines: 80,
statements: 80
}
}
}
}

but this doesn't output a new folder with the combined report.
Is there a way to do this?
