Online .NET Compiler ⚜️

Supports : C#, VB, F#, Console, ASP.NET MVC

We are a group of .NET developers who are sick and tired of starting Visual Studio,
creating a new project and running it, just to test simple code or try out samples from other developers.

Eval 👾

if you know about the dot notation, but are ignorant of the subscript notation, you might write:

eval("myValue = myObject." + myKey + ";"); 

〰 instead of :

myvalue = myObject[myKey]; 

The eval form is much harder to read.
This form will be significantly slower because it needs to run the compiler just to execute a trivial assignment statement ❗️

What is Unit Test ❓

A unit test is a piece of a code (usually a method) that invokes another piece of code and checks the correctness of some assumptions afterward. ✅

If the assumptions turn out to be wrong, the unit test has failed. ❌

A unit is a method or function.

Properties of a good unit test ✅

A unit test should have the following properties :

1️⃣ It should be automated and repeatable.

2️⃣ It should be easy to implement.

3️⃣ It should be relevant tomorrow.

4️⃣ Anyone should be able to run it at the push of a button.

5️⃣ It should run quickly.

6️⃣ It should be consistent in its results.

7️⃣ It should have full control of the unit under test.

8️⃣ It should be fully isolated (runs independently of other tests).

9️⃣ When it fails, it should be easy to detect what was expected and determine how to pinpoint the problem.

Why use isolation frameworks❓

An isolation framework is a set of programmable APIs that makes creating fake objects much simpler, faster, and shorter than hand-coding them. 💨

The Safe Green Zone ✅

Locate your integration and unit tests in separate places.

By doing that, you give the developers on your team a safe green test area that contains only unit tests, where they know that they can get the latest code version.

They can run all tests in that namespace or folder, and the tests should all be green.

If some tests in the safe green zone don’t pass ❌ ,
there’s a real problem, not a (false positive) configuration problem in the test.
