This will work with any type of assignment:

int i = 0;
while ((i = i + 1) < 3)

{ System.out.println(i); }

The "((i = i + 1) < 3)" will get no coverage with the mouseover hint being: "Expression evaluated to true 0 times, false 0 times."


The following is no problem however:

int i = 0;
while ((++i) < 3) { System.out.println(i); }

Here is another example that won't work:

public static void inlineAssignment() {
Class<?> c = Integer.class;
while ((c = c.getSuperclass()) != null)

{ System.out.println(c); }

}

Since Clover is primarily a coverage tool, I marked this issue Major.
