### Question:
Conflict { public String toString() { return path + "\t" + ancestor.toString() + "\t" + ours.toString() + "\t" + theirs.toString(); } Conflict(@NonNull String path, @NonNull ObjectId ancestor, @NonNull ObjectId ours,
            @NonNull ObjectId theirs); ObjectId getAncestor(); ObjectId getOurs(); ObjectId getTheirs(); String getPath(); boolean equals(Object x); int hashCode(); String toString();  }### Answer:
@Test public void testToString() { ObjectId id1 = ObjectId.valueOf("abc123000000000000001234567890abcdef0000"); ObjectId id2 = ObjectId.valueOf("abc123000000000000001234567890abcdef0001"); ObjectId id3 = ObjectId.valueOf("abc123000000000000001234567890abcdef0002"); Conflict conflict = new Conflict("Points/1", id1, id2, id3); String conflictStr = conflict.toString(); assertTrue(conflictStr.contains("Points/1")); assertTrue(conflictStr.contains(id1.toString())); assertTrue(conflictStr.contains(id2.toString())); assertTrue(conflictStr.contains(id3.toString())); }
