The Assert class contains assertion methods for setting invariants in the code.
All method calls will be conditionally included only in a development
build, unless specified explicitly. See BuildOptions.ForceEnableAssertions.
The inclusion of an assertion is controlled by the UNITY_ASSERTIONS
define.
Assert throws exceptions whenever an assertion fails.
If a debugger is attached to the project (System.Diagnostics.Debugger.IsAttached is true),
AssertionException is thrown to pause the execution and
invoke the debugger.

AreApproximatelyEqual | Assert the values are approximately equal. |
AreEqual | Assert that the values are equal. |
AreNotApproximatelyEqual | Asserts that the values are approximately not equal. |
AreNotEqual | Assert that the values are not equal. |
IsFalse | Return true when the condition is false. Otherwise return false. |
IsNotNull | Assert that the value is not null. |
IsNull | Assert the value is null. |
IsTrue | Asserts that the condition is true. |
