How to check if two files have the same content?

Question

I am using mocha/supertest/should.js to test REST Service

GET /files/<hash> returns file as stream.

How can I assert in should.js that file contents are the same?

it('should return file as stream', function (done) {     var writeStream = fs.createWriteStream('test/fixtures/tmp.json');          var req = api.get('/files/676dfg1430af3595');     req.on('end', function(){        var tmpBuf = fs.readFileSync('test/fixtures/tmp.json');        var testBuf = fs.readFileSync('test/fixtures/test.json');             // How to assert with should.js file contents are the same (tmpBuf == testBuf )        // ...             done();     }); });

Surprisingly, no one has suggested Buffer.equals. That seems to be the fastest and simplest approach and has been around since v0.11.

So your code would become tmpBuf.equals(testBuf)
