javascript - Is jasmine supposed to execute specs in the order they are declared or in a random order?

Question

un-comment the last spec. All hell breaks loose... why?

describe('test', function() {
  var index = 1;

  it('test 1', function() {
    expect(index).toBe(1);
    index++;
  });

  it('test 2', function() {
    expect(index).toBe(2);
    index++;
  });

  it('test 3', function() {
    expect(index).toBe(3);
    index++;
  });

  it('test 4', function() {
    expect(index).toBe(4);
    index++;
  });

  it('test 5', function() {
    expect(index).toBe(5);
    index++;
  });

  it('test 6', function() {
    expect(index).toBe(6);
    index++;
  });

  it('test 7', function() {
    expect(index).toBe(7);
    index++;
  });

  it('test 8', function() {
    expect(index).toBe(8);
    index++;
  });

  it('test 9', function() {
    expect(index).toBe(9);
    index++;
  });

  it('test 10', function() {
    expect(index).toBe(10);
    index++;
  });

  // it('test 11', function() {
  //   expect(index).toBe(11);
  //   index++;
  // });

});

thanks to @PWKad for pointing out this happens when there are more than 10 tests.

Yes, Jasmine executes the specs (it) in order. There was an issue from 2.3.0 to 2.3.3 with more than 10 specs. I hit the same issue in 2.3.3, the issue is fixed in 2.3.4.

I just used 2.3.4 in place of 2.3.3 and my 15 tests finally passed.
