2 | 2 | """Tests for code execution (%run and related), which is particularly tricky. |
|
3 | 3 | |
|
4 | 4 | Because of how %run manages namespaces, and the fact that we are trying here to |
|
5 | 5 | verify subtle object deletion and reference counting issues, the %run tests |
|
6 | 6 | will be kept in this separate file. This makes it easier to aggregate in one |
|
7 | 7 | place the tricks needed to handle it; most other magics are much easier to test |
|
8 | 8 | and we do so in a common test_magic file. |
|
9 | 9 | |
|
10 | 10 | Note that any test using `run -i` should make sure to do a `reset` afterwards, |
|
11 | 11 | as otherwise it may influence later tests. |
