.rdb file missing in test for `#GC6` "Read a string value"

Platform Bug Reports
1

Adding the results for the “Read a Key” test and “Read a string value” which shows that the .rdb file exists there, but not in the next test.

I log the files found in the -dir path to the console. You can see the .rdb file in the first test but not in the 2nd, resulting in FileNotFoundError

@porcupine-578 This is actually expected behavior, as we’re testing whether your code can handle the case when the RDB file doesn’t exist.

Please refer to the note in Read a key #jz6:

  • The RDB file provided by --dir and --dbfilename might not exist. If the file doesn’t exist, your program must treat the database as empty.

Ah okay great, thank you for the quick reply!
