### Question:
MphChlOlciOp extends MphChlBasisOp { @Override protected void configureSourceSamples(SourceSampleConfigurer sampleConfigurer) throws OperatorException { sampleConfigurer.defineSample(0, "rBRR_07"); sampleConfigurer.defineSample(1, "rBRR_08"); sampleConfigurer.defineSample(2, "rBRR_10"); sampleConfigurer.defineSample(3, "rBRR_11"); sampleConfigurer.defineSample(4, "rBRR_12"); sampleConfigurer.defineSample(5, "rBRR_18"); }    }### Answer:
@Test public void testConfigureSourceSample() { final TestSourceSampleConfigurer sampleConfigurer = new TestSourceSampleConfigurer(); MphChlOlciOp mphChlOp = new MphChlOlciOp(); mphChlOp.configureSourceSamples(sampleConfigurer); final HashMap<Integer, String> sampleMap = sampleConfigurer.getSampleMap(); assertEquals("rBRR_07", sampleMap.get(0)); assertEquals("rBRR_08", sampleMap.get(1)); assertEquals("rBRR_10", sampleMap.get(2)); assertEquals("rBRR_11", sampleMap.get(3)); assertEquals("rBRR_12", sampleMap.get(4)); assertEquals("rBRR_18", sampleMap.get(5)); }
