+    The tests are written in this way:
+    there are five different elements may appear in a ruby container: rb, rt,
+    rbc, rtc, and inline content.
+
+    In each test file, there are two parts: all elements are wrapped inside a
+    <ruby> in one part, they are directly contained by a <p> in the other part.
+
+    In each part, all permutations of pairs of two adjacent elements are
+    presented, so there are 5*5+1=26 elements.
+
+    The five test files share the same structure, but with different element
+    type order.
