Evaluation

The test fails because secret.txt might be restored from the backup and it contains sensitive data.

You can see the call to isExcludedFromBackupKey at 0x100004594 and the associated file, secret.txt at 0x10000443c.

Note: Using artificial intelligence we're able to decompile the disassembled code and review it. The output is a human-readable version of the assembly code. The AI decompiled code may not perfect and might contain errors but, in this case, it clearly shows the use of isExcludedFromBackupKey and the associated file secret.txt.
