The test tab defines how tests are done, The default is to test all models built. By default, the test data is created by randomly splitting the build data into two equal-sized subsets. If you plan to tune the models, you must test the models in the build node, not in a Test node.
You can specify no test. If you do perform a test, you can use all of the build data for test, modify the split ratio, or use a a test source for test.
Another way to test a model is to use a Test Node.
