    • Constructor Detail

      • TestClass

        public TestClass​(java.lang.Class<?> clazz)
        Creates a TestClass wrapping clazz. Each time this constructor executes, the class is scanned for annotations, which can be an expensive process (we hope in future JDK's it will not be.) Therefore, try to share instances of TestClass where possible.
