There are many non-destructive testing techniques. They’re not all suited to every type of application. For example, electromagnetic testing techniques don’t work on most composite materials, while X-rays and computed tomography are perfect. Similarly, ultrasounds are very versatile but require direct contact and appropriate coupling with the surface under test, which is not always possible.
