#caffe train/test/validation

[Benedetta89]

I'm a bit confused about the division between training set, test set and validation set. In creating the solver.prototxt file that defines the train parameters i have to define test_iter parameter ( that seems to be the number of iterations, that is how many batches of test images were sent into the network ). Why i have to define this parameter for training? Is test set used during training as validation set? Or does caffe do training and test at the same time ?
