Python-nose: A unittest-based testing framework for Python that makes writing and running tests easier
5 likes5,694 views
Nose is a Python testing framework that extends the built-in unittest framework. It makes writing and running tests easier by automating test discovery and running. Nose can be installed via pip and used by running nosetests on test files. Tests are written as unittest classes and methods. Nose supports configuration files, running tests in parallel, and integration with IDEs like Eclipse to automatically run tests on file changes.

- 10. Automate your Unit tests with Nose and Eclipse Go to the project properties Dene a new programbuilder Set the location to the nosetest script Set the working directory to the project location ${workspace_loc:/html2docbook} Optional: append any command line options you want Go to the build optionstag and tick the launch in backgroundänd during auto builds.
