This python package contains functions to instrument your code / tests to create sequence diagrams (in markdown / mermaid) as the tests run.
The sequence diagrams show the runtime call hierachy of the code. They are saved as files in the repository, which you should check in.
You can choose to ignore specific functions, and private functions, to make diagrams readable in each context you are interested in.
The diagrams are useful documentation, and will stay up to date as they are automatically generated. Hopefully it will encourage us to have useful diagrams in the repo, with the appropriate levels of detail, which in turn will encourage us to structure the code well so it produces good diagrams, and to have tests at these levels of detail.
You can see an example of this package in use at docs-from-tests-example.
You can see an example of instrumenting a test at tests\test_hello_world.py
This test creates the following diagram
The diagram is reproduced here for convenience. It is a mermaid diagram, you may need to install a Browser Plugin or VsCode extension or similar to view it.
