Accuracy in question

[ORESoftware]

I have a Loopback server, which is similar to Express

There are certain routes that I simply know get hit by Loopback, for example, everything in the boot directory.

I am running a child_process like this:

              if (useIstanbul) {

                node = cp.spawn('istanbul', ['cover', 'server/server.js'], {
                  cwd: cwd,
                  env: Object.assign({}, process.env, {
                    NODE_ENV: 'prod', //will use server/config.local.js file in project, according to Loopback
                    // NODE_ENV: 'prod',
                    port: designatedPort,
                    DEBUG: 'loopback:datasource'
                  })
                });
              }
              else {
                node = cp.spawn('node', ['.'], {
                  cwd: cwd,
                  env: Object.assign({}, process.env, {
                    NODE_ENV: 'prod', //will use server/config.local.js file in project, according to Loopback
                    // NODE_ENV: 'prod',
                    port: designatedPort,
                    DEBUG: 'loopback:datasource'
                  })
                });
              }

but using Istanbul in this way, does not seem to generate accurate coverage reports.

Any idea why this might be?

For example, I know this file would have been run by Loopback and I can log it to be sure:

(because the above screenshot is from a file in server/boot

Turns out, it looks like Istanbul is 100% correct about this :) How bizarre.
