    How i can find out if Apple Hardware Test is installed to my Mac or do i need to use Apple Hardware Test over the Internet?

    I have 10.11.1 and this Mac should have AHT not Apple Diagnostics.

    I could boot to find out but is there another way to find out?

    It will be installed, it's in the firmware I think.

    Look for /System/Library/CoreServices/.diagnostics

    If it's not there, AHT is not installed.

    If you wish install it, try looking in THIS THREAD.
