why mocking is required in unit testing?

Mocking is a process used in unit testing when the unit being tested has external dependencies. The purpose of mocking is to isolate and focus on the code being tested and not on the behavior or state of external dependencies.

The unit test framework in Python is called unittest , which comes packaged with Python. Unit testing makes your code future proof since you anticipate the cases where your code could potentially fail or produce a bug. Though you cannot predict all of the cases, you still address most of them.

JUnit is a framework that helps with writing and running your unit tests. Mockito (or any other mocking tool) is a framework that you specifically use to efficiently write certain kind of tests. ... In order to do that, you very often have to create "test doubles" that you provide to an object of your "class under test".

The reason for making the getters and setters private is to make the corresponding part of the object's abstract state private. That's largely independent of the decision to use getters and setters or not. They can provide a place for adding your debug code while testing.

Marks a test method. xUnit.net does not require an attribute for a test class; it looks for all test methods in all public (exported) classes in the assembly. Set the Skip parameter on the [Fact] attribute to temporarily skip a test.

It is not a bad practice, it just means that you did not think your code through. The condition is required to tell the loop when to finish looping.

try has almost no expense at all. Instead of doing the work of setting up the try at runtime, the code's metadata is structured at compile time such that when an exception is thrown, it now does a relatively expensive operation of walking up the stack and seeing if any try blocks exist that would catch this exception.

The Unit testing is the testing technique in which the smallest unit of the program is tested. On the other hand, the System testing relies on the high-level design specification and checks whether the system implementation satisfies the system requirement specification or not.

2 Answers. Most of the code I have seen in Apex has a SOQL in the constructor. Well having a SOQL in the constructor is not bad practice unless its very bad and heavy SOQL which increases the page load time. ... In that case the constructor SOQL is bit overkill.

C# Unit Tests with Mocks provide an easy way of reducing unwanted dependencies when writing unit tests. One of the best and shortest definition for mocking is mocking is creating objects that simulate the behavior of real objects.

You can't mock private methods. Moq (and few other frameworks) uses Castle Project's DynamicProxy to generate proxies on the fly at run-time so that members of an object can be intercepted without modifying the code of the class. That interception can only be done on public virtual and protected virtual methods.
