I want to introduce you to the live code test, from Visual studio 2017.
Is a great idea for produce without stop every time to execute tests or even debugg your code.
The live test unit, run your unit test in the background, every time you modify your code being tested, you are notified when your test fails and when tests performed successfully (which is indicated by the green check mark, "✓"),
the live tests indicates when an line of your code is note covered in tests.
Maybe you are think, is not too heavy? yes, is so... but it is a great helper, and it can save some time during coding.
I hope to see features like this in another IDEs, or even in Editor (Visual code plzzz) hahahahaha
