Have a look at the univariate, bivariate relationships and try to have the same relationships when creating the test data. Test data can be generated without any manual intervention. All these scenarios may not be possible for the data scientist to have with him and hence he may need to create some synthetic data to test the models. Poorly designed test data may not test all possible tests or real scenarios which will hamper the performance of the model. Test data needs to be precise and exhaustive to uncover the defects.
