File Difference Checker

Test-Node extension for KNIME Workbench version 4.4.0.v202104260810 by KNIME AG, Zurich, Switzerland

Used in regression tests to test if two files are equal. The node will compare two files given by flow variable and fails with an exception if the files are not equal. In that case the node stays not executed and the test will fail.

If you want to compare many files given by URIs you can also use the standard Table Difference Checker and use the URI Contents checker for the URI column


Test File
The file to compare with the reference file. It can be a local file on disk or an URL.
Reference File
The reference file. It can be a local file on disk or an URL.

Input Ports

Flow variable with the file name that should be compared to the reference
