*** Test Cases ***
MacOS formated ISO is mounted and correct size is reported
    [Documentation]  Mount a MacOS formatted ISO and check that its size is
    ...              detected correctly. Note that Linux is not able to 
    ...              mount this image. Note: Marathon was chosen because
    ...              its a reasonably small image. Large images will make 
    ...              this test take a LONG time.
    Given CD-ROM Drive is attached as SCSI ID 6
    When Insert Removable Media marathon.iso into SCSI ID 6
    Then the size of SCSI ID 6 is equal to the size of marathon.iso
    And the checksum of SCSI ID 6 is equal to the checksum of marathon.iso

ISO-9660 formated ISO is mounted correct size is reported
    [Documentation]  Mount a pre-made IDS-9660 formatted ISO and check 
    ...              that it is read correctly
    [Teardown]  Unmount SCSI ID 5
    Given CD-ROM Drive is attached as SCSI ID 5
    When Insert Removable Media ubuntu-12.04.5-server-amd64.iso into SCSI ID 5
    And Mount SCSI ID 5 as ubuntu
    Then SCSI ID 5 has been mounted at ubuntu
    And the size of SCSI ID 5 is equal to the size of ubuntu-12.04.5-server-amd64.iso
    And the filesystem type of SCSI ID 5 is iso9660
    And the file pics/debian.jpg in the ubuntu directory matches the original in ISO ubuntu-12.04.5-server-amd64.iso
    And the file install/vmlinuz in the ubuntu directory matches the original in ISO ubuntu-12.04.5-server-amd64.iso

CD-ROM Read Speed is as fast as expected
    [Documentation]  Check that the read speed  from the emulated CD-ROM is within
    ...              the expected range. This should detect if a change cause the
    ...              drive to slow down significantly
    Given CD-ROM Drive is attached as SCSI ID 2
    When insert Removable Media ubuntu-12.04.5-server-amd64.iso into SCSI ID 2
    Then the measured read speed for 1 megabytes of data from SCSI ID 2 is greater than 750 KB/s
    Then the measured read speed for 10 megabytes of data from SCSI ID 2 is greater than 950 KB/s
    And the measured read speed for 100 megabytes of data from SCSI ID 2 is greater than 950 KB/s


Create an ISO from a RaSCSI CD-ROM device and verify it matches
    [Documentation]  On the RaSCSI, we'll mount an ISO, then on the host system, we
    ...              will generate a new ISO from the emulated CD-ROM and make sure
    ...              that it matches the original
    [Teardown]  Remove temporary file dup_simtower.iso
    Given CD-ROM Drive is attached as SCSI ID 0
    When Insert removable media simtower.iso into SCSI ID 0
    And create an image named dup_simtower.iso from SCSI ID 0
    Then local file dup_simtower.iso matches RaSCSI file simtower.iso
