Debug tensorflow unit tests
<p>I find the <a href="https://stackoverflow.com/questions/34204551/run-tensorflow-unit-tests">link</a> which shows how to run the unit tests.</p>

<p>And I think it could get a better understanding about the source code by debug the unit tests.</p>

<p>I can debug the source code as the tensorflow python application run. But I don't know how to debug the unit test. I am new to bazel and gdb debug.</p>
