[coldbox-3.8.1] Error 'key [SLUG] doesn't exist' in created testRunner

Hi all,

I just finished writing a bundle of test cfc in MXUnit style, incorporating CFSelenium to create a set of browser tests.

The tests are running great, but I want to create a custom test runner, running just a directory (selenium) and in that directory, just run the currently working tests.

I created this runner with the following code:

`

<cfset rootPath = expandPath( rootMapping )>

<cfset testbox = new coldbox.system.testing.TestBox()>

#testbox.init( directory=rootMapping ).run(testSuites: [‘PartnerTest’,‘CustomerTest’])#

`

When I run this, I get an error saying: "key [SLUG] doesn’t exist’.

Can anybody see what is wrong with my code? I also tried using a list as the testSuites Argument, but with the same error as a result.

Hope you can help,

Kind regards,
Erik-Jan
