Online search and sorting out some of the concept of unit testing

Concept: Unit test is the smallest unit of software testing. Used to check if one or several of the related methods behave correctly.

1.3A Principle of unit testing

Arang: Arranging, initializing

Action: operation, execution

Assert: Assertion, result

2. Common assertion Methods

Areequal-asserts that two values are equal
Arenotequal-asserts that two values are not equal
Arenotsame-asserts that two objects are different objects
Aresame-asserts that two objects are the same object
fail-assertion that a test failed
Inconclusive-asserts that the result of a test is indeterminate. Visual Studio includes this assertion in its auto-generated methods, asking you to implement it yourself
Isfalse-asserts that a given conditional expression returns a value of False
Isinstanceoftype-asserts that a given object is an instance of a specified type
Isnotinstanceoftype-asserts that a given object is not an instance of a specified type
Isnotnull-asserts that an object is not a null value
Isnull-asserts that an object is a null value
Istrue-asserts that a given conditional expression returns a value of True

3. Common frame mocks for unit tests

Build unit tests by using some mock object frames.
