### Question:
FdMine implements FunctionalDependencyAlgorithm, RelationalInputParameterAlgorithm { @Override public ArrayList<ConfigurationRequirement<?>> getConfigurationRequirements() { ArrayList<ConfigurationRequirement<?>> configurationSpecifications = new ArrayList<>(); configurationSpecifications.add(new ConfigurationRequirementRelationalInput(INPUT_FILE_TAG)); return configurationSpecifications; }  @Override ArrayList<ConfigurationRequirement<?>> getConfigurationRequirements(); @Override void execute(); @Override void setResultReceiver(FunctionalDependencyResultReceiver resultReceiver); @Override void setRelationalInputConfigurationValue(String identifier, RelationalInputGenerator... values); @Override String getAuthors(); @Override String getDescription();  }### Answer:
@Test public void testGetConfigurationRequirements() { assertThat(algorithm.getConfigurationRequirements(), hasItem(isA(ConfigurationRequirementRelationalInput.class))); }
