        ## Overview
        
        Syrupy is a pytest snapshot plugin. It enables developers to write tests which assert immutability of computed results.
        
        ## Motivation
        
        The most popular snapshot test plugin compatible with pytest has some core limitations which this package attempts to address by upholding some keys values:
        
        - Extensible: If a particular data type is not supported, users should be able to easily and quickly add support.
        - Idiomatic: Snapshot testing should fit naturally among other tests cases in pytest, e.g. `assert x == snapshot` vs. `snapshot.assert_match(x)`.
        - Soundness: Snapshot tests should uncover even the most minute issues. Unlike other snapshot libraries, Syrupy will fail a test suite if a snapshot does not exist, not just on snapshot differences.
        
        ## Installation
        
        ```shell
        python -m pip install syrupy
        ```
        
        ## Usage
        
        ### Basic Usage
        
        In a pytest test file `test_file.py`:
        
        ```python
        def test_foo(snapshot):
            actual = "Some computed value!"
            assert actual == snapshot
        ```
        
        when you run `pytest`, the above test should fail due to a missing snapshot. Re-run pytest with the update snapshots flag like so:
        
        ```shell
        pytest --update-snapshots
        ```
        
        A snapshot file should be generated under a `__snapshots__` directory in the same directory as `test_file.py`. The `__snapshots__` directory and all its children should be committed along with your test code.
        
        ### Advanced Usage, Plugin Support
        
        ```python
        import pytest
        
        @pytest.fixture
        def snapshot_custom(snapshot):
            return snapshot.with_class(
                io_class=CustomIOClass,
                serializer_class=CustomSerializerClass,
            )
        
        def test_image(snapshot_custom):
            actual = "..."
            assert actual == snapshot_custom
        ```
        
        Both `CustomIOClass` and `CustomSerializerClass` should extend `syrupy.io.SnapshotIO` and `syrupy.io.SnapshotSerializer` respectively.
        
        ## Uninstalling
        
        ```python
        pip uninstall syrupy
        ```
