`warning: Environment check 'affe' may be indeterminable, add to Manifest/provides/environment or use class name prefix`

[konichan7]

When i compile qooxdoo project with typescript (qx compile --typescript), got some warning messages.

qx.test.core.Environment: [157,6 to 159,8] warning: Environment check 'affe' may be indeterminable, add to Manifest/provides/environment or use class name prefix
qx.test.core.Environment: [170,6] warning: Environment check 'affe' may be indeterminable, add to Manifest/provides/environment or use class name prefix
qx.test.dev.unit.Requirements: [65,6 to 67,8] warning: Environment check 'qx.test.requirement.syncTrue' may be indeterminable, add to Manifest/provides/environment or use class name prefix
qx.test.dev.unit.Requirements: [81,6 to 83,8] warning: Environment check 'qx.test.requirement.syncFalse' may be indeterminable, add to Manifest/provides/environment or use class name prefix

as @cboulanger said, these warning messages seems to be related to test codes, i think that it would be better make not shown to user so that they don't need to handle it. Or fix some parts of message more friendly to user, EG Manifest/provides/environment/ -> Manifest/provides/environmentChecks.

thanks.
