Method Detail

• configs

  public static List<Object[]> configs()

  Returns a list of arrays containing ExtractorAsserts.SimulationConfig objects to exercise different extractor paths.

  This is intended to be used from tests using ParameterizedRobolectricTestRunner or org.junit.runners.Parameterized.

• assertSniff

  public static void assertSniff​(Extractor extractor,
                                 FakeExtractorInput input,
                                 boolean expectedResult)
                          throws IOException

  Asserts that Extractor.sniff(ExtractorInput) returns the expectedResult for a given input, retrying repeatedly when FakeExtractorInput.SimulatedIOException is thrown.

  Parameters:

  extractor - The extractor to test.

  input - The extractor input.

  expectedResult - The expected return value.

  Throws:

  IOException - If reading from the input fails.

• assertAllBehaviors

  public static void assertAllBehaviors​(ExtractorAsserts.ExtractorFactory factory,
                                        String file)
                                 throws IOException

  Asserts that an extractor behaves correctly given valid input data.

  • Calls Extractor.seek(long, long) and Extractor.release() without calling Extractor.init(ExtractorOutput) to check these calls do not fail.
  • Calls assertOutput(Extractor, String, byte[], Context, boolean, boolean, boolean, boolean, boolean) with all possible combinations of "simulate" parameters.

  Parameters:

  factory - An ExtractorAsserts.ExtractorFactory which creates instances of the Extractor class which is to be tested.

  file - The path to the input sample.

  Throws:

  IOException - If reading from the input fails.

• assertAllBehaviors

  public static void assertAllBehaviors​(ExtractorAsserts.ExtractorFactory factory,
                                        String file,
                                        String dumpFilesPrefix)
                                 throws IOException

  Asserts that an extractor behaves correctly given valid input data:

  • Calls Extractor.seek(long, long) and Extractor.release() without calling Extractor.init(ExtractorOutput) to check these calls do not fail.
  • Calls assertOutput(Extractor, String, byte[], Context, boolean, boolean, boolean, boolean, boolean) with all possible combinations of "simulate" parameters.

  Parameters:

  factory - An ExtractorAsserts.ExtractorFactory which creates instances of the Extractor class which is to be tested.

  file - The path to the input sample.

  dumpFilesPrefix - The dump files prefix appended to the dump files path.

  Throws:

  IOException - If reading from the input fails.

• assertBehavior

  public static void assertBehavior​(ExtractorAsserts.ExtractorFactory factory,
                                    String file,
                                    ExtractorAsserts.SimulationConfig simulationConfig)
                             throws IOException

  Asserts that an extractor consumes valid input data successfully under the conditions specified by simulationConfig.

  The output of the extractor is compared against prerecorded dump files whose names are derived from the file parameter as specified in the docs for ExtractorAsserts.AssertionConfig.dumpFilesPrefix.

  Parameters:

  factory - An ExtractorAsserts.ExtractorFactory which creates instances of the Extractor class which is to be tested.

  file - The path to the input sample.

  simulationConfig - Details on the environment to simulate and behaviours to assert.

  Throws:

  IOException - If reading from the input fails.

• assertBehavior

  public static void assertBehavior​(ExtractorAsserts.ExtractorFactory factory,
                                    String file,
                                    ExtractorAsserts.AssertionConfig assertionConfig,
                                    ExtractorAsserts.SimulationConfig simulationConfig)
                             throws IOException

  Asserts that an extractor consumes valid input data successfully successfully under the conditions specified by simulationConfig.

  The output of the extractor is compared against prerecorded dump files.

  Parameters:

  assertionConfig - Details of how to read and process the source and dump files.

  simulationConfig - Details on the environment to simulate and behaviours to assert.

  Throws:

  IOException - If reading from the input fails.
