## About

The *bmi-tester* is a command-line utility and Python library for testing
Basic Model Interface (BMI) implementations.

## Requirements

The *bmi-tester* requires Python 3. Additional dependencies can be found
in the project's *requirements.txt* file and can be installed using either
*pip* or *conda*.

In addition to these requirements, the *bmi-tester* also requires the
*gimli.units* package, which is a Python interface to the *udunits2*
C library, which is not available through *pip* but can be installed
using *conda*.

If you are a developer of the *bmi-tester* you will also want to install
additional dependencies for running the project's tests to make sure
that things are working as they should. These dependencies are listed
in *requirements-testing.txt* and can all be install with either *pip*
or *conda*.

## Installation

To install, first create a new environment in which the project will be
installed. This, although not necessary, will isolate the installation
so that there won't be conflicts with your base *Python* installation.
This can be done with *conda* as,

```bash
conda create -n bmi-tester python=3
conda activate bmi-tester
```

### Stable Release

The *bmi-tester*, and its dependencies, can most easily be installed
with *conda*,

```bash
conda install bmi-tester -c conda-forge
```

### From Source

After downloading the *bmi-tester* source code, run the following from
the project's top-level folder (the one that contains *pyproject.toml*) to
install into the current environment,

```bash
pip install -e .
```

## Usage

You can access the *bmi-tester* from the command line with the *bmi-test*
command. Use the *--help* option to get a brief description of the
command line arguments,

```bash
bmi-test --help
```

The *bmi-test* command takes a single argument, the name of the entry point
of the class that implements the BMI you would like to test. To demonstrate
how this works, we will use the *Hydrotrend* model as an example. To install
the Python BMI for *Hydrotrend*, use *conda*,

```bash
conda install pymt_hydrotrend -c conda-forge
```

Once installed, the following will test the BMI implementation for the
*Hydrotrend* class,

```bash
bmi-test pymt_hydrotrend:Hydrotrend
```

The entry point is given as *\:\*. That is, in Python you would
import the *Hydrotrend* class as,

```python
>>> from pymt_hydrotrend import Hydrotrend
```
