How to use the jest-prosemirror.p function in jest-prosemirror

it('returns false when selection is active', () => {
    const {
      state: { selection },
    } = createEditor(doc(p('inline'), p('aba', 'awesome')));
    expect(selectionEmpty(selection)).toBeFalse();
  });

it('should return false for ambiguous locations', () => {
    const { state } = createEditor(doc(p('Something this  is a word')));
    expect(getSelectedWord(state)).toBeFalse();
  });

it('returns true for full selection', () => {
    const { state } = createEditor(doc(p('Something')));
    expect(atDocStart(state)).toBeTrue();
  });

it('removes nested inline nodes at specified position', () => {
    const {
      state: { tr },
    } = createEditor(doc(p('one', atomInline())));
    const newTr = removeNodeAtPosition({ pos: 4, tr });
    expect(newTr).not.toBe(tr);
    expect(newTr.doc).toEqualProsemirrorNode(doc(p('one')));
  });
});

it('returns false when no selection', () => {
    const { state } = createEditor(doc(p('Something')));
    expect(atDocEnd(state)).toBeFalse();
  });

.callback(content => {
        expect(content.state.doc).toEqualProsemirrorNode(doc(p('@awesome')));
      });
  });
