Question

In my JS Test Driver configuration file, I’m excluding unit tests from code coverage calculation by putting them under test instead of load.

However, I can’t do this for dependencies, like jQuery of Underscore.js, since they need to be loaded before my code.

Is there any way around this? Or do I just deal with the slow code coverage runs and statistic clutter?

Answer 1

Solution 1:

There’s a way using the ´args´ parameter as Greg says, but that way unfortunately you have to specify the full path, as this (asuming Windows):

plugin:
- name: "coverage"
  jar: "lib/coverage-1.3.2.jar"
  module: "com.google.jstestdriver.coverage.CoverageModule"
  #Here put the files that have to be ignored by coverage. Non-existent files do not harm.
  args: "
    D:\\apache\\htdocs\\XTIME\\js\\lib\\ext-all.js,
    D:\\apache\\htdocs\\XTIME\\js\\lib\\jquery-1.7.2.min.js,     
  "

For linux filesystems, you don’t have to use double slash.

Solution 2:

There’s also a patched jar for 1.3.5 on this thread that allows you to exclude files that match a regular expression, so you’d have:

plugin:
- name: "coverage"
  jar: "lib/coverage-1.3.5.serve-patch.jar"  #this patched jar allows to use excludesRegex
  module: "com.google.jstestdriver.coverage.CoverageModule"
  args: "excludesRegex: /js/lib/.*\\.js$"

The /js/lib/.*\.js$ regex means “Exclude all the .js files located inside js/lib“. (With this patch you don’t have to worry about Windows backslashes)

I prefer this way much more, as it’s portable because it does not depend on a specific path for your application.

You can download the patched version here (look for Comment 11 in the thread).

Hope this helps.
