Development and Implementation of a File System for Gannet Virtual ...

C. Testing
TestCase00
Creates, writes to, verifies and then deletes a 6000-byte file. This test fails if the
write and read function calls fail. This test also fails if the data written to the file
does not match the data read from the file.
1. Reads a file named “testing.txt” from disk drive using C++ std library. The data is
stored on a first buffer.
2. Creates a file named “head-gfs.txt” on GannetFS file system.
3. Write the data from first buffer to “head-gfs.txt” file.
4. Closes “head-gfs.txt” file.
5. Reopens “head-gfs.txt” file.
6. Reads the file and stores the data on second buffer.
7. Verifies the first and second buffers using memcmp() function.
8. Write the data from second buffer to disk drive named “buffout_big.txt” using
C++ std library.
9. Removes “head-gfs.txt” file from GannetFS file system.
10. Compares “testing.txt” with “buffout_big.txt” using diff function.
TestCase01
Creates, writes to, verifies, and then deletes a 2048-byte file. This test fails if the
mkdir, write, or seek function calls fail. This test also fails if the data written to the
file does not match the data read from the file.
1. Reads a file named “testing.txt” from disk drive using C++ std library. The data is
stored on a first buffer.
2. Creates a directory named “/test-one”.
3. Creates a file named “/test-one/testFile-one” on GannetFS file system.
4. Write the data from first buffer to “/test-one/testFile-one” file.
5. Closes “/test-one/testFile-one” file.
6. Reopens “/test-one/testFile-one” file.
7. Reads the file and stores the data on second buffer.
8. Verifies the first and second buffers using memcmp() function.
9. Write the data from second buffer to disk drive named “buffout_big.txt” using
C++ std library.
10. Removes “/test-one/testFile-one” file from GannetFS file system.
11. Removes directory named “/test-one”.
