how to set a particular test file as the first when running mocha?

Is there a way to set a particular test file as the first in mocha and then the rest of the test files can execute in any order.

There is no direct way, but there is certainly a solution to this. Wrap your describe block in function and call function accordingly.

firstFile.js

function first(){
    describe("first test ", function () {
        it("should run first ", function () {

            //your code

       });
    });
   }

module.exports = {
     first
}

secondFile.js

 function second(){

      describe("second test ", function () {
         it("should run after first ", function () {

                    //your code

             })
          })
        }

  module.exports = {
     second
}

Then create one main file and import modules. main.spec.js

 const firstThis = require('./first.js)
 const secondSecond = require(./second.js)

 firstThis.first();
 secondSecond.second();

In this way you can use core javaScript features and play around with mocha as well. This is the solution I have been using since long. would highly appreciate if anyone would come with better approach.

One technique that can be used is to involve number in test filename such as

01-first-test.js
02-second-test.js
03-third-test.js

So by defining this, the test will be executed from first test until third test.

No. There is no guarantee your tests will run in any particular order. If you need to do some setup for tests inside of a given describe block, try using the before hook like so.
