Unit tests for the Tpdd class

The unit tests require a physical TPDD to be connected to the serial port with a disk in the drive. The disk can be formatted as part of the tests so make sure that the disk is one that is ok to be wiped.

Attributes that must be used with the tests are:

• no-tpdd - For tests not requiring a TPDD to be connected.
• tpdd-off - For tests that check for correct behaviour when there is a lack of communication with a TPDD
• no-disk - For tests that check for correct behaviour when there is no disk in the drive
• disk - For disk operation tests.
• format - Used for the disk formatting test.

If the test suite is run without specifying attributes, it will report failures!

Example test run with the disk in a TPDD2 drive:

nosetests -v .\Tpdd_test.py -a 'disk' -a 'tpdd2' -a 'format'

Tpdd_test.test_checksum()

Test that the checksum method returns a valid checksum

Tpdd_test.test_copy_file_from_bank_0()

Copies a file from the TPDD

Tpdd_test.test_copy_file_from_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_copy_file_to_bank_0()

Copies a file to the TPDD

Tpdd_test.test_copy_file_to_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_delete_file_from_bank_0()

deletes a file from the TPDD

Tpdd_test.test_delete_file_from_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_dir_empty_disk_bank_0()

Check to see if any empty disk reports the correct number of bytes

Tpdd_test.test_dir_empty_disk_bank_1()

Check that an empty disks reports the correct number of bytes on bank 1

Tpdd_test.test_file_exists_bank_0()

Checks the file exists method

Tpdd_test.test_file_exists_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_file_not_exists_bank_0()

Checks the file exists method with non-existent files

Tpdd_test.test_file_not_exists_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_format()

Formats the disk in the drive and checks for errors

Tpdd_test.test_parse_invalid_filename()

Tests various invalid filenames

Tpdd_test.test_parse_invalid_return_code_item()

Test valid return codes

Tpdd_test.test_parse_valid_filename()

Tests various valid filenames

Tpdd_test.test_parse_valid_return_code_item()

Test valid return code items. The last test item is an invalid code however the format of the return message is valid.

Tpdd_test.test_rename_invalid_file_bank_0()

Checks the file rename method with invalid filenames

Tpdd_test.test_rename_invalid_file_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_rename_valid_file_bank_0()

Checks the file rename method with valid filenames

Tpdd_test.test_rename_valid_file_bank_1()

If the disk is a TPDD 2 disk do the test again on the second bank

Tpdd_test.test_return_code_item_invalid()

Test invalid return code descriptions

Tpdd_test.test_return_code_item_valid()

Test valid return code descriptions

Tpdd_test.test_status_no_disk()

Test for a ‘no disk’ or ‘disk change’ error with no disk in the drive

Tpdd_test.test_status_no_drive()

Test for a valid status with the drive not powered on

Tpdd_test.test_status_valid()

Test for a valid status with the disk in the drive
