"find out if it's broken" isn't the same thing as cable properties/quality.
If the cable fails to carry a signal, or fails to do so without interference, it should be pretty easy to determine this. Failure to do this would make it "faulty".

Lets say the cable catches fire due to high resistance/poor isolation (used at 40-50C or close to oven exhaust, causing thermal runaway) - is it broken? In that regard you can use a lamp cable to connect an oven - it will totally work for 5seconds, it might burn down later, though.
This is so incredible false, cable quality varies greatly:
- wires, gauge and material. Copper is expensive and some cheat using aluminum or Al plated copper. Gold plated terminals, tinned copper, etc.
- wire material and single/multi strand determines resistance and current rating, along with loses in the cable.
- insulation and sleeves can be made from different materials with a lot of properties, incl. max temperature, flame retardant and so on: pvc - cheap, rubber - expensive, nylon/polyamid - expensive, silicon - very expensive.
And that just touches the basics...
