You can use a multimeter set to resistance. It should show 0 resistance or full scale deflection on an analogue meter, if intact.

You can also use a small lamp (drawing less current than the fuse) connect it to the battery with a wire, including the fuse in circuit. If the lamp lights, the fuse is Ok.
