In order to use a conditional jump a condition must be tested. Testing a condition here refers only to the act of checking the flags, the actual jumping is described under Conditional jumps. x86 tests conditions by relying on the EFLAGS register, which holds a set of flags that each instruction ca...

Based on the state of the flags the CPU can either execute or ignore a jump. An instruction that performs a jump based on the flags falls under the generic name of Jcc - Jump on Condition Code1.
