### Question:
Algorithm implements Serializable, Comparable<Algorithm> { public Algorithm setName(String name) { this.name = name; return this; } protected  Algorithm();  Algorithm(String fileName);  Algorithm(String fileName, Set<Class<?>> algorithmInterfaces);  Algorithm(String fileName, String name, String author, String description,
                   Set<Class<?>> algorithmInterfaces); @Id @GeneratedValue long getId(); void setId(long id); @Column(name = "fileName", unique = true) String getFileName(); Algorithm setFileName(String fileName); @Column(name = "name", unique = true) String getName(); Algorithm setName(String name); String getAuthor(); Algorithm setAuthor(String author); String getDescription(); Algorithm setDescription(String description); boolean isInd(); Algorithm setInd(boolean isInd); boolean isFd(); Algorithm setFd(boolean isFd); boolean isCid(); Algorithm setCid(boolean isCid); boolean isMd(); Algorithm setMd(boolean isMd); boolean isCfd(); Algorithm setCfd(boolean isCfd); boolean isUcc(); Algorithm setUcc(boolean isUcc); boolean isCucc(); Algorithm setCucc(boolean isCucc); boolean isOd(); Algorithm setOd(boolean isOd); boolean isMvd(); Algorithm setMvd(boolean isMvd); boolean isBasicStat(); Algorithm setBasicStat(boolean isBasicStat); boolean isDc(); Algorithm setDc(boolean isDc); boolean isRelationalInput(); Algorithm setRelationalInput(boolean isRelationalInput); boolean isDbConnection(); Algorithm setDbConnection(boolean isDbConnection); boolean isTableInput(); Algorithm setTableInput(boolean isTableInput); boolean isFileInput(); Algorithm setFileInput(boolean isFileInput); HashSet<AlgorithmType> getAlgorithmTypes(); void setAlgorithmTypes(HashSet<AlgorithmType> algorithmTypes); boolean hasAlgorithmType(AlgorithmType algorithmType); Algorithm setAlgorithmType(AlgorithmType algorithmType, boolean hasAlgorithmType); @XmlTransient @JsonIgnore @OneToMany( fetch = FetchType.EAGER, mappedBy = "algorithm", cascade = CascadeType.ALL ) @OnDelete(action = OnDeleteAction.CASCADE) List<Execution> getExecutions(); @XmlTransient @JsonIgnore Algorithm setExecutions(List<Execution> executions); @Override boolean equals(Object o); @Override int hashCode(); @Override int compareTo(Algorithm o); @Override String toString();  }### Answer:
@Test public void testUniqueAlgorithmName() { HibernateUtil.clear(); Algorithm algorithm1 = new Algorithm("example_ind_algorithm.jar"); algorithm1.setName("name"); try { HibernateUtil.store(algorithm1); } catch (EntityStorageException e) { fail(); } Algorithm algorithm2 = new Algorithm("example_ucc_algorithm.jar"); algorithm2.setName("name"); try { HibernateUtil.store(algorithm2); } catch (EntityStorageException e) { } HibernateUtil.clear(); }
