v1.2.0

Changed

• Improves clarity of error messages for large component comparisons

  Old logic:

  raise AssertionError with large string difference between JSON objects if the component did not match the snapshot, which led to difficult to read error message like:

  AssertionError: {'pro[136 chars]en': 'another one'}, 'namespace': 'dash_html_c[77 chars]Div'} != {'pro[136 chars]en': [1, 2, 3]}, 'namespace': 'dash_html_compo[73 chars]Div'}
  

  New logic:

  raise AssertionError with large string difference between JSON objects if the component does not match the snapshot, and
  add new details section about the first local mismatch between the component and snapshot:

  DETAILS:
  
  <class 'list'> != <class 'str'>
  CONTEXT 1:
  
  {"children": [1, 2, 3]}
  
  CONTEXT 2:
  
  {"children": "another one"}
  

  or

  DETAILS:
  
  P != Span
  CONTEXT 1:
  
  {"type": "P", "props": {"children": "another one"}, "namespace": "dash_html_components"}
  
  CONTEXT 2:
  
  {"type": "Span", "props": {"children": "another one"}, "namespace": "dash_html_components"}
