Which would still be misleading :-)

Even better is “How to test whether a string is a valid representation
of an integer?”

I say that's better because it gets to the relevant point of asking
*which* representations you want to test for – what qualifies as valid
for your particular use case, and what does not. There's no single right
answer; the programmer must choose exactly what they want to test for.
