tests: Add integration tests
Add a simple cli-based test infrastructure with a few tests to prepare future code changes. Note that these cannot be run on Travis CI as it does not support FUSE. Expected output: $ tests/run.sh 1 Running unit tests: OK *** running test_corruption.sh 2 Reading file: OK 3 Reading corrupted file: OK 4 Reading file with MAC: OK 5 Corruption with MAC returns IO error: OK *** running test_file_expansion.sh 6 Creating files of different sizes: : OK 7 Growing file: OK 8 Internal modification: OK *** All tests OK
