Re: [Bacula-devel] tests/virtual-backup2-test says OK but is actually failing?

[Kern Sibbald <kern@xxxxxxxxxxx>]

Hello,

Several points:

1. You have apparently modified the test.  What you show below does not at all 
correspond to the virtual-backup-test that we are currently running.

2. In a number of the regression tests, there is a need for more testing and 
verification.  This is a project that we (mostly Eric) are working on, but it 
is not at all easy to use portable shell scripting to check the details of a 
job.

3. If you want to submit some code that improves the testing, we would be 
happy to see it, but one needs to take a lot of care to make sure it is 
portable and will run on all Unix flavors ...

Regards,

Kern
