Hardness is a characteristic of a material not a fundamental physical property It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation
The method setUp() will be invoked after the test class has been built and before any test method is run In this example we will be running the group fast so aFastTest() will be invoked while aSlowTest() will be skipped Things to note: No need to extend a class or implement an interface
1 Load-pull measurements are a class of non-50-Ω measurements used during the design model extraction and performance testing of various RF/microwave devices A main topic of discussion with load-pull testing is the evaluation of amplifier designs in a large signal sense Load-pull testing
Jul 07 2020NDT refers to nondestructive testing It is an approach to testing that involves evaluating the weld without causing damage It saves time and money including the use of remote visual inspection (RVI) x-rays ultrasonic testing and liquid penetration testing In most welds quality is tested based on the function for which it is intended
