// You don't even need to write any code to test -- you can just test values and run that, even
|
|
// though you wouldn't do that in real life :) `assert!` is a macro that needs an argument.
|
|
// Depending on the value of the argument, `assert!` will do nothing (in which case the test will
|
|
// pass) or `assert!` will panic (in which case the test will fail). So try giving different values
|
|
// to `assert!` and see which ones compile, which ones pass, and which ones fail :)
