DREAM (Data REgression Analysis Manager) is the tool to use for data testing. Software development nowadays has excellent tools for testing code, but testing the data produced and/or processed by the code is often ignored. This not seldomly leads to bugs which could have been avoided with the right tool. DREAM is exactly such a tool.

More than diff

DREAM compares two datasets on various levels. It will recognize structural changes and takes the context of changes into account when presenting them. To give a quick overview, DREAM features a dashboard that quickly shows an overview of the test results.
