Getting Started with V Programming
By :

Writing tests in V is straightforward. In this section, we will explore three simple concepts that will get you started with writing tests in V. They are as follows:
assert
keyword to compare the actual and expected outcome._test.v
extension.test_
.In the next subsection, we will learn the syntax of the assert
keyword and its usage in V.
In V, you can use the assert
keyword to compare the outcome of a function you are writing tests for with the expected outcome. Following is the syntax that shows how to use the assert
keyword in V followed by a Boolean expression:
assert boolean_expression
In the preceding syntax, we can see that the assert
keyword is followed by an expression whose output must always evaluate to a Boolean result. If the Boolean result is true
then the assertion succeeds, otherwise...
