// Test plan:
//  * Two types - int and char
//  * Two signs - signed and unsigned
//  * Square that - we have input and output types.
// Thus, there are total of (2*2)^2 == 16 tests.
// These are all the possible variations/combinations of casts.
// However, not all of them should result in the check.
// So here, we *only* check which should and which should not result in checks.
