the test depends on the CPLD content. You need to integrate the CPLD into the circuit, use a logic analyzer, or create a computer-based tester.

there is a development software ProChip Designer, originally from Atmel, now from Microchip. The ProChip Designer contain third-party simulator.

I use CUPL to make CPLD content. For programming I have VP-880 from Wellon. The CPLD test I do on breadboard. The CUPL has also a software simulator, but the test on breadboard is more secure and fast. If I test a chip select decoder, I need only DIP switches and logic probe or LED diode. If I test a counter inside the CPLD, I use function generator and LED display made from TIL311.
