missing-files

Nodejs function to compare two directories and return files not found in second directory. Useful for ensuring that all files have matching test files, however having a file does not mean it's tested!

Installation

npm install missing-files

Usage

missingFiles(masterDir, compareDir, excludes, callback)

• masterDir : directory to be compared against (i.e. source)
• compareDir : directory that 'should' match (i.e. tests)
• excludes: array of regex/string to filter results
• callback: function(error, result)

Usage in a test

test('ensure that all source files have matching test file', function(t) {
    t.plan(1);

    var sourceDir = path.resolve(__dirname,  '../lib'),
        testDir = path.resolve(__dirname, '.'),
        excludes = [
            /^\myprotectedpath\//,
            /^\/models\//,
            '.DS_Store',
            /(.*).json/
        ];

    missingFiles(sourceDir, testDir, excludes, function(error, result) {
        t.deepEqual(result, [], 'all files are covered');
    });
});
