Vitest: All 'describe' logic runs 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. Typically putting logic directly into describe blocks in vitest is NOT recommended.

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");
    });
  });
});

Instead of plain desribe: describe+beforeAll

Use describe+beforeAll if you want GWT with vitest/describe spec.
