How to use relative path in meteor project

I am trying to use anyNpmPackage in meteor project on test.

I have done meteor npm install anyNpmPackage

In my package.js i have

Package.onTest(function(api) {
    api.addFiles('tests/server/methods.js', 'server');

Now anyNpmPackage uses jsonpath internally

On of the line of jsonpath code in grammer.js is

myModule = fs.readFileSyn`c(require.resolve("../include/module.js"));

And when i do the meteor test

I get error Error: Cannot find module '../include/module.js'

And when i debugged just above that line

console.log(fs.readdirSync('../../')) the result was [ 'server', 'web.browser' ]
and console.log(__dirname) was resulting to /node_modules/jsonpath/lib

What i need is that when i do fs.readdirSync it should result into the original files from my codebase from from the temp env directory created under /tmp by meteor.

Any workaround for this issue?
