Error handling using child_process.execSync in NodeJs

This is my NodeJs snippet:

const {execSync} = require('child_process');
  testoutput = execSync('make test');

Here I am getting stdout as output to testoutput variable from the execSync process if the make process is completely exited. But, if the make test process encounters an stderr error then I am getting an error in NodeJs.

How can I store the stderr message to an output variable testoutput if the make process does not exit and store stdout in variable testoutput if the process exits well with stdout output.

>Solution :

To catch errors with execSync(), you need a try/catch around your call as errors will throw an exception.
