SharpDevelop integrates with
NUnit allowing you to run and debug your unit tests inside the
First you will need a project to hold your tests. From the
File menu, select New and then select
Solution... to open up the New Project dialog box.
Expand the C# category and select Class Library
from the list of available templates. Choose the project's
name and location and then click the Create button.
Now create a simple test class. Select the name of the project
in the Project Explorer, right click, select Add and
then select New Item.... Select the Unit Test
template from the C# category, give it a name and then
select the Create button. Adding this template to the
project will automatically add the required reference to
NUnit.Framework. The code shown below is an example of a very basic
test class which you can copy into the file just created.
public class MyTest
public void FailingTest()
Assert.Fail("This test fails.");
From the View menu select Tools and then Unit
This opens up the Unit Tests window.
To run the test from the Unit Tests window click the
Run tests toolbar button , or right click a
test, and select Run tests.
After a test run, unit tests that pass are shown in green, those
that fail in red and those that have not been run in yellow.
As the tests are run messages are displayed in the Output
window and after the tests have completed failing tests are added
to the Errors window.
Tests can be run from the source code editor by right clicking
the test method or test class and selecting one of the Unit Testing
The menu options allow you to run the test and show the result
in the Unit Tests window, or run the test with the debugger
so you can step through the code, or run the test and check for
code coverage. The last two menu items are also available when
running tests from the Unit Tests window.
