Testing power supplies/ transient testing

Right, so I have just finished building my power supply. Its a 0-50V 0-4Amps bench supply.
I have an electonic DC load that can do transient tests on power supplies.
I just recently purchased this load.
How do I go about testing my power supply. I have no idea at what current rating to set the dc load and at what frequency i should set it's on/ off cycle.
What waveforms should I expect to see ?
I have done a capture of the on waveform at switch on. Looks good no overshoot.
I forgot to mention the dc load has the following parameters that can be set for transient testing.
Start current
End current
Rise tim
fall time
On time
Off time
Hope someone can give me a couple concrete steps to test my power supply
