When the plugin cannot use its default behavior for figuring out the dot-notation for the project's CFCs, you'll need to tell the plugin what to do. You do this at the project or directory level, in the MXUnit Properties cfc path property.
The MXUnit Eclipse plugin needs to turn your files (c:\inetpub\wwwroot\myproject\MyTest.cfc) into the correct cfc path "dot notation" which ColdFusion understands (perhaps it's "myproject.MyTest").
Below I'll describe several different scenarios, each using a different filesystem and project configuration example
By default, the plugin will start at the last "segment" of the file path (In this case, "SomeTest"), and travel up the path, a segment at a time, prepending the next segment it encounters and adding a "." (period). It will do this until it reaches the "root" of the project. In this case, the logic would "look" like this (roughly):
loop 1: SomeTest
loop 2: tests.SomeTest
loop 3: MyProject.tests.SomeTest
loop 4: "I'm at the root of the project... stop deriving the path". Return MyProject.tests.SomeTest
loop 1: MyBusinessObjectTest
loop 2: test.MyBusinessObjectTest
loop 2: at project root; sees cfcpath property as "components". Appends that to test.MyBusinessObjectTest, with a period. Return "components.test.MyBusinessObjectTest"
Imagine this scenario: Your applications live at d:\apps, and you have a monster project in Eclipse set up at d:\apps. You have some subdirs that look like: d:\apps\v1\Client1\tests, d:\apps\v2\Client1\tests, etc. And you've added CF mappings like so:
Imagine this scenario: Your applications live at d:\apps, and you have a monster project in Eclipse set up at d:\apps. You have some subdirs that look like: d:\apps\App1\tests, d:\apps\App2\tests, and so forth. You have mappings in CF set up that points "app1" to d:\apps\app1, "app2" to d:\apps\app2, etc.
In this case, the easiest choice is to use the "empty" root indicator. In this example, here's what to do:
