To use a Node.js global variable in Mocha tests, you can simply set the variable as a global variable in your test file or in a separate file that is required by your test file.


Here is an example:

  1. Create a Node.js global variable in a separate file, for example globalVariable.js:
1
global.myGlobalVariable = 'Hello, world!';


  1. Require the global variable file in your test file, for example test.js:
1
2
3
4
5
6
7
require('./globalVariable.js');

describe('My test suite', function() {
  it('should access the global variable', function() {
    console.log(myGlobalVariable); // Output: Hello, world!
  });
});


  1. Run your Mocha test using the mocha command:
1
mocha test.js


In this example, the global variable myGlobalVariable set in globalVariable.js is accessible in the Mocha test file test.js.


This way, you can use Node.js global variables in your Mocha tests by setting them as global variables and requiring them in your test files.
