As engineers, when deciding what kind of testing is most appropriate, your project type and end goals need to be considered. What other factor(s), if any, do you think should also be considered when determining the best testing methods for a specific project? - Knowing what kind of information is needed should also be a basis for deciding what testing method is best. Depending on which properties you're looking to characterize in a sample, you might choose different methods of testing. Also...
