# Testing Image Sample Set

Similar to the Training Image Sample Set, you will want to have your testing sample image set contain representative variations of what you expect to encounter during runtime. The key differentiation between the training sample image set and the testing sample image set is that the testing set are not included during the training of the tool.

You will also want to label the testing sample image set in the same way that you label the training sample image set. This will allow you to perform statistical analysis of training sample image set, to determine how well the tool is generalizing its results.
