Exclude files from test

I'm using a code for requiring all src files except main.js for coverage. What I need is to add one more file to ignore, or ignore all files that have this extension.

const srcContext = require.context('../../src/renderer', true, /^\.\/(?!main(\.js)?$)/)

This is what I'm using, I need to also exclude _icons.scss or exclude all .scss from coverage. I tried implementing some new regex but it does not work as expected

Thanks!

You may use the following updated pattern:

/^\.\/(?!(?:main(\.js)?|.*\.scss)$)/
         ^^^           ^^^^^^^^^^

The main point here is to add an alternative to the part that matches the file names after ./.

Full pattern details:

  • ^ - start of string
  • \.\/ - a literal ./ substring
  • (?!(?:main(\.js)?|.*\.scss)$) - a negative lookahead that will fail the match if the following patterns match:
    • (?:main(\.js)?|.*\.scss) - either main or main.js substrings (at the end of the string)
    • | - or
    • .*\.scss - any 0+ chars other than line break chars (.*) up to the last .scss substring that is at...
    • $ - the end of the string.
