Test

Tests allow you to assert on the computed values that are the output of an insight. Tests are run with the visivo test command.

Example

tests:
  - name: Test One
    if: ">{ ${ ref(Tested Insight).props.type } == 'scatter' }"
    assertions:
      - ">{ sum( ${ ref(Tested Insight).props.x } ) == 7 }"
      - ">{ ${ ref(Tested Insight).props.x[0] } == 1 }"

Note

Quote each >{ ... } assertion (as above). Unquoted, YAML reads a leading > as a folded block-scalar indicator, so the assertion never reaches the parser as an eval string.

The numpy library is available in test expressions.
