Adding Tests to Characterize Existing Behavior
We need to change code in writeSamples. Let’s start with a couple tests!

| TEST(WavReader_WriteSamples, WritesSingleSample) { |
| char data[] { "abcd" }; |
| uint32_t bytesPerSample { 1 }; |
| uint32_t startingSample { 0 }; |
| uint32_t samplesToWrite { 1 }; |
| reader.writeSamples(&out, data, startingSample, samplesToWrite, bytesPerSample); |
| CHECK_EQUAL("a", out.str()); |
| } |
