Development setup

Virtual environment

Create a virtual environment and install the dependencies:

python3 -m venv ./venv
source ./venv/bin/activate
pip install -r ./requirements.txt --upgrade

Install development dependencies, as well:

pip install -r ./requirements-dev.txt --upgrade

Allow pre-commit to automatically run on git commit:

pre-commit install

Above, requirements.txt should mirror the dependencies section of pyproject.toml.

If using VSCode, restart it or follow these steps:

• Ctrl + Shift + P
• Select Interpreter
• Choose ./venv/bin/python.

Tests

Run the tests as follows:

This command runs all tests:

pytest .

If you want to skip network interaction tests run:

pytest -m "not networkInteraction"

We have some tests fetching mainnet transactions that are quite time consuming. To skip those, run this command:

pytest -m "not mainnet"

Generate test coverage report

First, we run the tests using coverage:

coverage run -m pytest .

Then, we can generate a report in the terminal using:

coverage report

We can also generate a html report using:

coverage html

Re-generate the docs

Each time a new module/submodule is added it needs to be added to the docs, as well. To do so cd in the root directory then run the following command:

sphinx-apidoc -f -o docs/ dharitri_py_sdk/ '*_test.py' '*constants.py'

This command will regenerate the .rst files for each module, excluding the tests and the constants.py files.

Also, each time a new version is released, the conf.py file should be updated accordingly.

Re-generate protobuf files:

protoc dharitri_py_sdk/core/proto/transaction.proto --python_out=. --pyi_out=.

Note that protoc must be installed beforehand. Use the same version as the one referenced in requirements.txt. For example, if we reference protobuf==5.29.4 in requirements.txt, then use protobuf v29.4.
