Vitest

From Order of Operation with Describe: All 'describe' logic prior to all 'it'

The logic within the describe blocks is executed BEFORE any of the IT blocks are touched.

Think of describe logic as declaration that that gets processed before any of the IT implementation logic runs.

Code

import { describe, it, expect, test } from 'vitest';

describe('describe-level-1', () => {
  console.log("STDOUT: describe-level-1 pre it level-1");

  it('it-level-1', () => {
    console.log("STDOUT: it-level-1");
  });

  console.log("STDOUT: describe-level-1 post it level-1");

  describe('describe-level-2a', () => {
    console.log("STDOUT: describe-level-2a");

    it('it-level-2a', () => {
      console.log("STDOUT: it-level-2a");
    });

    describe('describe-level-3', () => {
      console.log("STDOUT: describe-level-3");

      it('it-level-3 1', () => {
        console.log("STDOUT: it-level-3 #1");
      });

      it('test-level-3 2', () => {
        console.log("STDOUT: it-level-3 #2");
      });
    });
  });

  describe('describe-level-2b', () => {
    console.log("STDOUT: describe-level-2b");

    it('it-level-2b', () => {
      console.log("STDOUT: it-level-2b");
    });
  });
});
