+ * This test checks different alignments for the icon against the label.
+ * The icon is then moved around the label in each of it's alignments.
+ * The final relayed out size is checked to confirm the layout has been done correctly.
+ *
+ * There is an Icon which has 0 width and height, but with 75 padding on all sides.
+ * - Therefore total width and height are both 150.
+ *
+ * There is a Label which has "an unknown" width and height, but with 30 padding on all sides.
+ * - Therefore total width and height are 60+x and 60+y respectively.
+ * Where x & y are the width and height of the text.
+ *
+ * The width of the button will always expand to the largest of the icon and label sizes (plus padding).
+ * So We use the padding to help us determine the orientation is correct for each alignment.
