### Question:
RemoteProctorSpecificationSource extends DataLoadingTimerTask implements ProctorSpecificationSource { @VisibleForTesting static ProctorSpecifications parseExportedVariables( final String content, final ProctorClientApplication client ) throws IOException { final Properties exportedVariables = VarExportedVariablesDeserializer .deserialize(content); final Set<ProctorSpecification> specifications = new HashSet<>(); for (final String key : exportedVariables.stringPropertyNames()) { if (!key.startsWith("specification")) { continue; } final String json = exportedVariables.getProperty(key); try { final ProctorSpecification specification = OBJECT_MAPPER.readValue(json, ProctorSpecification.class); specifications.add(specification); } catch (final IOException e) { LOGGER.error("Failed to parse variable " + key + ": " + json + " from " + client, e); } } if (specifications.isEmpty()) { throw new IOException( "no specification can be parsed from exported variables from " + client ); } return new ProctorSpecifications(specifications); } RemoteProctorSpecificationSource(final int httpTimeoutMillis,
                                            final int executorThreads,
                                            final ProctorReader trunk,
                                            final ProctorReader qa,
                                            final ProctorReader production); @Override RemoteSpecificationResult getRemoteResult(final Environment environment,
                                                     final AppVersion version); @Override Map<AppVersion, RemoteSpecificationResult> loadAllSpecifications(final Environment environment); @Override Map<AppVersion, ProctorSpecifications> loadAllSuccessfulSpecifications(final Environment environment); @Override Set<AppVersion> activeClients(final Environment environment, final String testName); @Override Set<String> activeTests(final Environment environment); @Override boolean load(); void shutdown();  }### Answer:
@Test public void testExportedVariableParser() throws Exception { try (final InputStream exportedVariables = RemoteProctorSpecificationSourceTest.class .getResourceAsStream("exportedVariables.txt")) { final String content = IOUtils.toString(exportedVariables); final ProctorClientApplication client = new ProctorClientApplication( "testapp", "http: "http: new Date(), "version" ); final ProctorSpecifications result = RemoteProctorSpecificationSource .parseExportedVariables(content, client); assertThat(result.asSet()) .hasSize(1) .first() .satisfies(s -> assertThat(s.getTests()) .containsKey("my_tst") ); } }
