# Test Harness

Every ColdBox application template comes with a nice test harness inside of a `tests` folder.

![](https://3733350408-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LA-UVvJIdbk5Kfk3bDs%2F-LA-Ue7pk25llbkg6Fcu%2F-LA-UnH0ajEZYggayvZ6%2Ftestharness.png?generation=1523647987128203\&alt=media)

Here is a breakdown of what it contains:

* `Application.cfc` - A unique application file for your test harness. It should mimic exactly the one in your root application folder
* `resources` - Some basic testing resources or any of your own testing resources
* `results` - Where automated results are archived
* `runner.cfm` - The HTML runner for your test bundles
* `specs` - Where you will be writing your testing bundle specs for integration testing, unit testing and module testing.
* `test.xml` - Your ANT runner

## Application.cfc

The `Application.cfc` for your tests is extremly important as it should mimic your applications real `Application.cfc`.

```javascript
component{

    // APPLICATION CFC PROPERTIES
    this.name                 = "ColdBoxTestingSuite" & hash(getCurrentTemplatePath());
    this.sessionManagement    = true;
    this.sessionTimeout       = createTimeSpan( 0, 0, 15, 0 );
    this.applicationTimeout   = createTimeSpan( 0, 0, 15, 0 );
    this.setClientCookies     = true;

    // Create testing mapping
    this.mappings[ "/tests" ] = getDirectoryFromPath( getCurrentTemplatePath() );
    // Map back to its root
    rootPath = REReplaceNoCase( this.mappings[ "/tests" ], "tests(\\|/)", "" );
    this.mappings["/root"]   = rootPath;
    
    public void function onRequestEnd() { 
		structDelete( application, "cbController" );
		structDelete( application, "wirebox" );
	}

}
```

Please note that we provide already a mapping to your root application via `/root`. We would recommend you add any ORM specs here or any other mappings here as well.

**Tip:** Make sure all the same settings and configs from your root `Application.cfc` are replicated in your tests `Application.cfc`
