-Starting with version 5.0 the report viewer is bundled in JPlag and can be used locally. This behavior can be controlled with the "--mode" option.
-By default, JPlag will process the source files and produce a results.zip. After that the report viewer is started on localhost and the generated report will be shown in your browser.

Your submissions will neither be uploaded to a server nor stored permanently. They are saved in the application as long as you view them. Once you refresh the page, all information will be erased.

+The end-to-end test module contains tests that report any chance in the similarities reported by JPlag.
 There are two kinds of tests:
 1. Simple tests that fail if the similarity between two submissions changed
 2. Gold standard tests

+A gold standard test serves as a metric for the change in detection quality. It needs a list of plagiarism instances in the data set.
+JPlag outputs comparisons split into those that should be reported as plagiarism and those that shouldn't.
 The test will fail if the average similarity on one of those groups changed. In contrast to the other kind of test, this offers a rough way to check if the changes made JPlag better or worse.
