Having the following function:
public int Suma (int numero1, int numero2){
return numero1+numero2;
}
Be in Java or C# .
Is there a way to test this function without having to invoke it in the MAIN?
So if I have several functions or methods of the classes in my project, I have some way to test them one by one (hardcode the parameters that I want), without having to instantiate the classes or call the functions in the body main (main)?
To do so in Visual Studio 2013 or higher
In previous versions I do not know if it's the same process, but not It must be very different.
1.- You must add a Test Project, on your solution, do the following:
Right click > Add New Project > Visual C # > Testing > Unit Test Project
2.- You must import the references to your Unit Test Project (they can be other projects of your same solution or already compiled dlls) that you want to test.
3.- The Test Project creates a class similar to this one by default.
[TestClass]
public class UnitTest1
{
[TestMethod]
public void TestMethod1()
{
}
}
4.- Suppose you have a class called Operaciones.cs in another project and you import it into the Test Project to test its methods.
public class Operaciones
{
public int Suma(int numero1, int numero2)
{
return numero1 + numero2;
}
}
5.- This way you would make a Test of the Sum method in your Test Project.
using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using DemoUtils; /*Es la referencia del proyecto que contiene la clase
Operaciones*/
namespace UnitTestProject1
{
[TestClass]
public class UnitTest1
{
[TestMethod]
public void TestMethod1()
{
Operaciones operacion = new Operaciones();
Assert.AreEqual(10, operacion.Suma(5, 5));
}
}
}
In the previous code, you can specify a class of Operations, and with Assert.AreEqual you indicate that the value of the first parameter must be Equal to the result that you will obtain from your Sum method > for the test to be completed.
There are other methods of Assert that you can go testing according to your requirements.
6.- To start your unit test, right click on TestMethod1 and click on Run tests or with the shortcut Ctrl + R, T. p>
I hope you find it useful.
