Slurm provides a variety of tools that allow a user to manage and understand their jobs. This tutorial will introduce these tools, as well as provide details on how to use them.
The squeue command is a tool we use to pull up information about the
jobs in queue. By default, the squeue command will print out the

Writing tests for new code is a critical part of keeping napari maintainable as
it grows. Tests are written in files whose names
begin with test_* and which are contained in one of the _tests directories.
There are a few things to keep in mind when writing a test where a Qt event
loop or a napari.Viewer is required. The important thing is that any widgets
you create during testing are cleaned up at the end of each test:
