How to set execution order of mocha test cases in multiple files

I have two javascript files which contain mocha test cases.

//----------abc.js -------------

describe("abc file", function(){
  it("test 1" , function(){
    assert.equal(20 , 20); 
  });
}); 

//---------xyz.js--------------
describe("xyz file", function(){
      it("test 1" , function(){
        assert.equal(10 , 10); 
      });
    });

I have put them in a folder called test and when I execute the mocha command the first file(abc.js) is always executed before xyz.js. I thought this might be due to alphabetical ordering and renamed the files as

abc.js => xyz.js
xyz.js => abc.js

but still, the content of the xyz.js (previously abc.js) is executed first. How can I change the execution order of these test files?

Solution 1:

In the second file, require the first one:

--- two.js ---
require("./one")

Mocha will run the tests in the order the describe calls execute.

Solution 2:

I follow a totally seperate solution for this.

Put all your tests in a folder named test/ and Create a file tests.js in the root directory in the order of execution

--- tests.js ---
require('./test/one.js')
require('./test/two.js')
require('./test/three.js')

And in the tests files one.js, two.js and so on write your simple mocha tests

this way if you want to run them in the order you have defined then just run mocha tests.js
