Testing for pen ink longevity


One of my colleagues got asked a question about testing the ball point pen's ink longevity. Question was like, If you have a pen which lasts for 10 KMs, how would you test for that claim? Your inputs on this question please.

There are plenty of test cases of pen. You may find that ink can be tested in many ways. For example, making sure it stays on during the cold and extreme hot temperature. So these are some of the good things that come out.
