In the switching characteristics section of a BJT datasheet I often see test conditions like "Ib1=Ib2=1mA". I understand this is base current but what exactly do they mean by Ib1 and Ib2? Example: https://www.mccsemi.com/pdf/Products/MMBT3904(SOT-23).pdf
Thanks in advanced.

It means that the current for charging the Base is the same as the current used to discharge the Base capacitance when they do fall time testing.
An exemplary circuit to do so is shown in this datasheet.
