  @param expectedValue the given value to compare the actual observables value to.
  @param offset the given positive offset.
  @return  {@code this} assertion object.
  
  @throws java.lang.NullPointerException if the given offset is <code>null</code>.
  @throws java.lang.AssertionError if the actual observables value is not equal to the expected one.
