Home > Evaluate and Apply Nodes > Apply Node > Edit Apply Node > Test Node > Automatic Settings
By default, the option Automatic Settings are selected for a Test node. Automatic Settings result in the following behavior:
When a model input node is connected, all models are added to the specification.
When a model input node is disconnected, all models are removed from the specification. The test node may become invalid.
When a model input node is edited in the following ways, the resultant behavior is as follows:
If models are added, then model specifications are automatically added to the Test node.
If models are removed, then the specifications are removed from the Test node.
If models are changed, then the following is done:
The Test node is updated to ensure the algorithm is consistent.
If the target changes and there is only one node as input to the Test node, then the node is updated to reflect the new target and keep all the models. Also, the test input data is validated to ensure that it still has the new column target.
If there are multiple Model nodes as input to the Test nodes, then the models with the changed target are automatically removed.
If Automatic Settings is deselected, then you must edit the node to reflect all changes to the input. Models are validated if they are added.
