This course explains basic and advanced non-destructive testing methods used in the Oil & Gas industry as well as the chemical industry. This video (Animation, Animated Video) explains the concept of Non-Destructive Testing Methods. Destructive Testing involves many activities like designing a set of test scripts, executing test scripts, raising bugs, closing bugs, and providing the pass or fail metrics to stakeholders at the end of the iteration. These important tests are conducted in a wide variety of ways – see examples below – and can detect defects or damage both on the surface of an item or within the component itself. The software shall never process or accept invalid input data, Regardless of the validity or correctness of input data, the software should always produce proper output data, In this technique, an application is intentionally made to fail the program to check the robustness of the application. Look at destructive testing, for example. Other testing methods, such as the X-ray and hydrostatic tests, are not destructive (NDT). Destructive testing is ultimately more expensive and wasteful, as inspectors must damage viable materials that could have been used during normal operations.
