Test loading a thuban session from a file |
Test loading a thuban session from a file |
10 |
|
|
11 |
|
The tests in this file (test_load.py) are always be the tests for the |
12 |
|
current version of the thuban file format. Tests for older versions can |
13 |
|
be found in the version specific test modules, e.g. test_load_0_2 for |
14 |
|
files created by Thuban 0.2. |
15 |
|
|
16 |
|
Maintenance of the test cases: |
17 |
|
|
18 |
|
When during a development period the file format is changed with respect |
19 |
|
to the last released version for the first, the tests here should be |
20 |
|
copied to the version specific test file. The round-trip tests which |
21 |
|
save the session again and compare the XML files should not be copied |
22 |
|
over as they only make sense here to make sure th that the files checked |
23 |
|
here are actually ones that may have been written by the current thuban |
24 |
|
version. |
