//the test verifies:
// 1) verifies that modifiers are correct for standard (1, 2, 3) mouse buttons
// TODO: 2) verifies that modifiers are correct for wheel
// TODO: 3)
// Case1. the test posts BUTTONx_MASK and verifies that paramString() contains correct modifiers and exModifiers
// Case2. the test posts BUTTONx_DOWN_MASK and verifies that paramString() contains correct modifiers and exModifiers
// Case3. the test posts getMaskForButton(n) and verifies that paramString() contains correct modifiers and exModifiers
// repeat all cases with SHIFT/ALT/CTRL modifiers verify that paramString() contains correct modifiers and exModifiers
// I'm verifying button, modifiers and extModifiers for now.
