We describe the process of verifying and validating FLASH, a parallel, multi-physics simulation code intended to model astrophysical environments. Verification tests are designed to test and quantify the accuracy of the code. Validation tests are meant to ensure that simulations meaningfully describe nature by comparing the results of simulations to relevant laboratory experiments. The centerpiece of the verification process is the re-engineered FlashTest toolkit, which is used both as a stand-alone testing application and as a manager for a nightly test-suite. FlashTest exercises the unit test framework now available in FLASH3, the most recently released version, as well as a variety of standard verification tests. We also present a validation example in which simulations were directly compared to a laboratory experiment. We discuss our findings and evaluate the agreement between simulations and experiment.
