It is always better to remove a component from the circuit for proper testing but most of the time a resistor can be tested with a DMM set to the appropriate ohm scale, the same with a diode where the DMM is set to diode setting.
A transistor is more complicated, you first have to find the base connector and with your DMM set to diode, NPN Transistor, with negative probe to the base and positive to emitter or collector the smallest reading will be the collector and the slightly higher reading will be the emitter, no reading mean that it can be a PNP transistor then you will need to swap your probes, still no reading or a very low reading will mean the transistor is damaged
In actuality tektronics do make a curve tracer oscilloscope to test active components . But the speed is very limited. So while it may tell you that the part is good or bad it will not tell you how good or how bad it will function in the actual circuit

Is a cathode positive or negative?
A cathode is negative. It attracts cations, which are positively charged.
0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
What are the two points on the end of a battery called?
anode and cathode
Why is there a plus and minus of batteries?
plus is the positive terminal (cathode) minus is the negative terminal (anode)
What is the function of cro?
CRO consists of a cathode ray tube which is having the vacuum conditions . The electron beam is emitted by a cathode at the rear end of the tube. This beam is accelerated and focused by one or more anodes. The rays then strike the front (other end) of the tube and produces a bright spot on the phosphorescent screen
How a Cathode Ray Oscilloscope is used to measure Alternating current?
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.
What is CRO and AFO?
Audio Frequency Oscilloscope and Cathode Ray Oscilloscope
What is the CRO?
Cathode ray oscilloscope
What is the heart of an oscilloscope?
cathode ray tube
What is the most important part of an oscilloscope?
The most important part of an oscilloscope is the cathode ray tube.
What you will do to measure voltage which is greater than voltage limit of the cathode ray oscilloscope?
change your resistance, its a little button, or if you are using an older oscilloscope, its a knob that will lower the sensitivity of the display. if it is something way higher than the oscilloscope can measure, you may have to run a resistor or transformer in the line.

What is the price of Cathode-ray oscilloscope in India?
500 $
Full form of CRO?

Why the speed of electron beam is greater than the light speed in cathode ray oscilloscope?
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
Can a Cathode Ray Oscilloscope measure DC Signal?
Yes.
