# How to Solve the ModuleNotFoundError With Pytest?

To fix the `ModuleNotFoundError` in pytest, you can start by making your `tests` directory a Python package.This can be achieved by including an empty `__init__.py` file to the directory:

```text
└── tests/
    ├── __init__.py  # Make sure to include this
    └── test_module_functions.py
```

If this does not solve the issue, you may need to modify the `__init__.py` file to adjust the Python path:

```python
[label __init__.py]
import sys
sys.path.append('.')
```

If you're still encountering errors, another approach involves configuring your project settings with a `pyproject.toml` file:

```text
[ pyproject.toml]

[tool.pytest.ini_options]
pythonpath = "src"
addopts = [
    "--import-mode=importlib",
]
```
