What changes were proposed in this pull request?
This PR proposes to add three new parameters to the
assertSchemaEqual:ignoreNullable,ignoreColumnOrderandignoreColumnNameto provide users with more flexibility in schema testing.Why are the changes needed?
To enhance the utility of
assertSchemaEqualby accommodating various common schema comparison scenarios that users might encounter, without necessitating manual adjustments or workarounds.Does this PR introduce any user-facing change?
Yes.
assertDataFrameEqualnow have the option to use the five new parameters:When set to True (default), the nullable property of the columns being compared is not taken into account and the columns will be considered equal even if they have different nullable settings.
When set to False, columns are considered equal only if they have the same nullable setting.
When set to False (default), columns are compared in the order they appear in the DataFrames.
When set to True, a column in the expected DataFrame is compared to the column with the same name in the actual DataFrame.
ignoreColumnOrder cannot be set to True if ignoreColumnNames is also set to True.
When set to False (default), column names are checked and the function fails if they are different.
When set to True, the function will succeed even if column names are different. Column data types are compared for columns in the order they appear in the DataFrames.
ignoreColumnNames cannot be set to True if ignoreColumnOrder is also set to True.
