### Question:
ActionRef { @Override public String toString() { return new StringBuilder().append(getClass().getSimpleName()) .append(" [path=") .append(path) .append(", cancel=") .append(cancel) .append(", refs=") .append(refs) .append("]") .toString(); } ActionRef(String path, boolean cancel, Collection<ActionRef> refs);  ActionRef(String path,
                     boolean cancel,
                     Collection<ActionRef> refs,
                     Function<Class<? extends Feature>, Feature> id); String getPath(); boolean hasCancel(); boolean isUnique(); Collection<ActionRef> getRefs(); @Override int hashCode(); @Override boolean equals(Object obj); @Override String toString();  }### Answer:
@Test void testToString() { assertEquals("ActionRef [path=path2, cancel=true, refs=[ActionRef [path=path, cancel=false, refs=[]]]]", actionRef2.toString()); }
