com.appiancorp.ps.automatedtest.fixture.SitesFixture Could not invoke constructor for com.appiancorp.ps.automatedtest.fixture.SitesFixture[0]

Hi, 

I am trying to run a test page but getting the following error. 

com.appiancorp.ps.automatedtest.fixture.SitesFixture Could not invoke constructor for com.appiancorp.ps.automatedtest.fixture.SitesFixture[0]

It is under this section.

I checked my jre version and chrome version both. Both are correct.
