Core Library

Miscellaneous notes on development and testing the core library.

Installation

When doing local development work, use poetry to manage dependencies and maturin to create a build of the combined python/rust project:

make install-deps

This effectively expands to:

poetry install
poetry run maturin develop --release

You can also run maturin just with poetry run maturin develop, which will be much faster to compile, but rust execution will be notably slower.

You'll also need a system-wide installation of esbuild. If you don't have one when you run the build pipline it will install one for you within ~/.cache/mountaineer/esbuild.

Development Utilities

Python Testing
```
$ make test
```
During testing we also support providing additional test-args that are passed to pytest. This helps you narrow down the scope of tests, add more verbosity, etc.:
```
$ make test test-args="-k test_extracts_iterable"
```
Python Linting
```
$ make lint
```
Rust Benchmarking
```
$ cargo bench
```
Diagnose errors in CI

At the moment, our main CI testing flows run on Linux/x86-64 architectures. We've observed some behavior there that isn't reproducable locally. To test locally on OS X you'll need build a representative docker image and then test within it:
```
$ docker build -t mountaineer .
$ docker run -it mountaineer
$ make install-deps
$ make test-integrations
```
