Development and usage of isolated IPA's has identified bugs in the transmission of the file descriptors between the pipeline handler and the IPA through. Add tests to identify these bugs and prevent regressions. This tests basically checks for two things: - Camera reconfigurations without stopping CameraManager - Fd leaks across IPA IPC boundary [1] Currently, it uses vimc, but can be easily changed to using another platform (for e.g. IPU3) by changing kCamId_ and kIpaProxyName_. The test performs kNumOfReconfigures_ (currently set to 10) reconfigurations of the camera. Each reconfiguration runs start(), capture(100ms), stop() of the camera. Hence, the test runs approximately for 1 second. For checking the fd leaks, the test monitors the /proc/$PROXY_PID/fd directory for open fds. It compares the number of open fds after each run to the number of open fds before the first run. If those two are found to be mis-matched, the test shall report failure. The test validates IPA IPC code paths which are used when the IPA is run in isolated mode. The CameraTest is constructed with the isolate flag set to enforce this.
