+## Fixtures
+
+This directory contains the [test fixtures](https://en.wikipedia.org/wiki/Test_fixture) and a simple testing framework for `rustypaste`.
+
+### Running fixtures
+
+1. Build the project in debug mode: `cargo build`
+2. Execute the runner script in this directory: `./test-fixtures.sh`
+
+### Adding new fixtures
+
+Create an appropriately named directory for the test fixture you want to add. e.g. `test-file-upload`
+
+Each fixture directory should contain the following files:
+
+```
+test-file-upload/
+├── config.toml
+└── test.sh
+```
+
+- `config.toml`: Contains the `rustypaste` configuration. See [the default configuration](../config.toml).
+- `test.sh`: Contains the helper functions for testing. The file format is the following:
+
+```sh
+#!/usr/bin/env bash
+
+setup() {
+  # preparation
+}
+
+run_test() {
+  # assertions
+}
+
+teardown() {
+  # cleanup
+}
+```
+
+These functions are executed in the order defined above.
+
+See the [test-file-upload](./test-file-upload/test.sh) fixture for an example.
+
+### Debugging
+
+Set the `DEBUG` environment variable to `true` while executing the runner script:
+
+```sh
+$ DEBUG=true ./test-fixtures.sh
+```
