Table Difference Checker
Test-Node extension for KNIME Workbench version 4.1.0.v201909231846 by KNIME AG, Zurich, Switzerland
Used in regression tests to test the created data table with a reference data table. The node will compare (depending on the dialog settings) the incoming tables during execute and fails with an exception if the tables are not equal (or do not meet the expectations). In that case the node stays not executed and the test will fail.
In the node's dialog, you can adjust how individual columns are compared. The default is to check for
exact equality. For certain column types you can relax the comparison by using special checkers.
Examples
are numeric column where you may want to use an epsilon or string columns where you may want to
ignore
different line feed characters (Windows vs. Unix). The special checkers are used for the cell
contents
as well as for the column domain (i.e. possible values and bounds).
In case a column is a collection, you can select a checker for the elements' type which is then
applied
to every element in the collection (except the Equality checker which does look into the collection).
In order to configure column, change the checker in the second column and if applicable configure it in the panel below the column table.
Options
- Ignore row IDs
- Select this option if you want to ignore the row IDs of the two tables. Use this option only if you know what you are doing. Row IDs are an integral part of any data table and they should not change during the lifetime of a node because this may break existing workflows.
