/**
 * Tests separated from the rest as they sometimes broke when ran in parallel.
 * (This happened for {@link #fontListingMakesNoSmoke()} returning a valid page.)
 * This is because each test can't have its own font cache in FOP, at least with FOP-0.96.
 * Solutions:
 * <ul>
 *   <li>Find a way to configure FOP-1.0.
 *   <li>Wait for next-to-FOP-1.0 version.
 *       <a href="http://xmlgraphics.apache.org/fop/changes.html#Changes+to+the+Font+Subsystem">FOP Changelist</a>
 *       says: "Reinstated support for being able to specify a font cache filepath in the fop
 *       user configuration."
 *   <li>(Current solution.) Refactor tests to move all font-related tests in one test class and use a
 *       monothreaded {@link org.novelang.testing.junit.MethodSupport}.
 * </ul>
