code: public static synchronized void mockStaticPartialStrict(Class<?> clazz, String... methodNames) {
          mockStaticStrict(clazz, Whitebox.getMethods(clazz, methodNames));
      }
docs: A utility method that may be used to mock several <b>static</b> methods
  (strict) in an easy way (by just passing in the method names of the
  method you wish to mock). Note that you cannot uniquely specify a method
  to mock using this method if there are several methods with the same name
  in {@code type}. This method will mock ALL methods that match the
  supplied name regardless of parameter types and signature. If this is the
  case you should fall-back on using the
  {@link #mockStaticStrict(Class, Method...)} method instead.
  
  @param clazz       The class that contains the static methods that should be
  mocked.
  @param methodNames The names of the methods that should be mocked. If
  {@code null}, then this method will have the same effect
  as just calling {@link #mockStatic(Class, Method...)} with the
  second parameter as {@code new Method[0]} (i.e. all
  methods in that class will be mocked).
