Can capacitors be directly tested
Is there any way to test capacitors while on the circuit board
No you can''t because there will be other impedances in parallel with it so the reading will be meaningless. Assuming one side of the ESR tested can be grounded without affecting the measurements, you could just disconnect one side of the capacitor and conduct the test whilst it''s still half soldered to the PCB.

Failure Modes in Capacitors When Tested Under a Time-Varying
Power-on failure has been the prevalent failure mechanism for solid tantalum capacitors in decoupling applications. A surge step stress test (SSST) has been previously applied to identify the critical stress level of a capacitor batch to give some predictability to the power-on failure mechanism [1]. But SSST can also be viewed as an electrically destructive
