Should you Unit Test simple properties?

Question

Should you Unit Test simple properties of a class, asserting that a value is set and retrieved? Or is that really just unit testing the language?

Example

Answer 1

My answer which is from former test manager viewpoint and currently a development manager ( responsible for software delivery in time and quality) viewpoint. I see people are mentioning pragmatism. Pragmatism is not a good adviser because it may pair up with laziness and/or time pressure. It may led you on the wrong way. If you mention pragmatism you have to be careful to keep your intentions on the track of professionalism and common sense. It requires humility to accept the answers because they might not that you want to hear.

From my viewpoint what is important are the next:

• you should find the defect as early as possible. Doing so you have to apply proper testing strategy. If it is testing properties then you have to test properties. If not, then don't do it. Both comes with a price.
• your testing should be easy and fast. The bigger part (unit, integration, etc.) of the code tested in build time is the better.
• you should do root cause analysis to answer the questions below and make your organization protected from the current type of error. Don't worry, another type of defect will come up and there will be always lessons to be learned.
  • what the root cause is?
  • how to avoid it next time?
• another aspect is the cost of creating/maintaining tests. Not testing properties because they are boring to maintain and/or you have hundreds of properties is ridiculous. You should create/apply tools which makes the woodcutting job instead of human. In general, you always have to enhance your environment in order to be more efficient.
• what other says are not good adviser - doesn't matter whether it was said by Martin Fowler or Seeman - the environment they are I'm pretty sure not the same as you are in. You have to use your knowledge and experience to setup what is good for your project and how to make it better. If you apply things because they were said by people you are respect without even thinking it through you will find yourself in deep trouble. I do not say that you don't need advises and/or other people help or opinion, you have to apply common sense to apply them.
• TDD does not answer two important question, however, BDD does give you answers for the questions below. But, if you follow only one, you won't have delivery in time and quality. So doesn't matter whether you are purist TDD guy or not.
  • what must be tested? ( it says everything must be tested - wrong answer in my opinion )
  • when testing must be finished?

All in all, there is no good answer. Just other questions you have to answer to get that temporary point where you are able to decide whether it is needed or not.
