Which is not done during unit testing?
Not every test you could conceivably write qualifies as a unit test. If you write code that stuffs things into a database or that reads a file from disk, you have not written a unit test. Unit tests don’t deal with their environment and with external systems to the codebase.
Should every function be unit tested?
The answer to the more general question is yes, you should unit test everything you can. Doing so creates a legacy for later so changes down the road can be done with peace of mind. It ensures that your code works as expected. It also documents the intended usage of the interfaces.
What do you need to know about unit testing?
However, an essential step before depending on it is to test the requirements. Most unit tests are not about testing business cases accurately. Most of them test the architecture of the code, conditions, exceptions, etc. So, it is crucial to test the algorithm/engine/utility parts extensively.
When do you call function in unit test?
The method that uses this function is either called on startup of the application or when beginning a test fixture. It is similar to Ryan’s post but uses LINQ, drops the System.Reflection requirement, does not cache the result, and is private to prevent (accidental) misuse.
What happens if you don’t do unit testing?
Meaning that if you don’t test by hand or another way, the unit tests won’t catch these potential hidden problems. Below, you can find an image from the quality gates which some of the teams in Microsoft use. As you may notice, there are many other practices beyond unit testing to ensure that the product quality standards are met.
How to determine if code is running as part of a unit test?
I have a unit test (nUnit). Many layers down the call stack a method will fail if it is running via a unit test. Ideally you would use something like mocking to setup the object that this method is depending on but this is 3rd party code and I can’t do that without a lot of work.
