+## Testing
+
+### Setting up Bats
+
+I have set up the Bats testing framework for this project. Here are the steps I took:
+
+1.  **Checked for Bats:** I first checked if Bats was installed by running `bats --version`. The command failed, indicating that Bats was not installed.
+2.  **Installed Bats:** I installed Bats using the command `sudo apt-get update && sudo apt-get install -y bats`.
+3.  **Verified Installation:** After the installation, I ran `bats --version` again and confirmed that it was installed correctly.
+4.  **Created a Test File:** I created a simple test file at `tests/basic.bats` to ensure that the testing framework was working.
+5.  **Ran the Test:** I ran the test using the command `bats tests/basic.bats` and it passed.
+
+This process confirms that the testing environment is now set up and ready for use.
+
+### Comprehensive Test Suite
+
+I have created a comprehensive test suite for the library, covering all public and internal functions. The process involved:
+
+1.  **Identifying all functions:** I listed all functions from `ollama_bash_lib.sh` to ensure complete coverage.
+2.  **Creating individual test files:** I created separate `.bats` files for each function or group of related functions in the `tests/` directory.
+3.  **Writing test cases:** I wrote multiple test cases for each function, covering:
+    *   Positive scenarios (correct usage and expected output).
+    *   Negative scenarios (error handling, invalid input).
+    *   Edge cases.
+4.  **Debugging and Fixing:** I encountered and fixed several issues during the testing process, including:
+    *   Incorrect assumptions about function behavior (e.g., `_is_valid_json`).
+    *   Bugs in the library code (e.g., `ollama_model_unload`).
+    *   Subshell issues in Bats tests that prevented state changes from being persisted.
+5.  **Ensuring all tests pass:** I ran the entire test suite and ensured that all 53 tests passed successfully.
+
+This comprehensive test suite will help to ensure the quality and stability of the library going forward.

-Future home of BATS test suite for Ollama Bash Lib
+# Ollama Bash Lib - Testing
+
+This directory contains the test suite for the Ollama Bash Lib. The tests are written using the [Bats (Bash Automated Testing System)](https://github.com/bats-core/bats-core).
+
+## Setting up the Test Environment
+
+To run the tests, you will need to have Bats installed.
+
+### Installing Bats
+
+You can install Bats using your system's package manager.
+
+**For Debian/Ubuntu:**
+```bash
+sudo apt-get update
+sudo apt-get install -y bats
+```
+
+**For macOS (using Homebrew):**
+```bash
+brew install bats-core
+```
+
+For other systems, please refer to the [official Bats installation guide](https://github.com/bats-core/bats-core#installing-bats-from-source).
+
+After installation, you can verify that Bats is installed correctly by running:
+```bash
+bats --version
+```
+
+## Running Tests
+
+To run the entire test suite, navigate to the root of the repository and run:
+```bash
+bats tests/
+```
+
+This will execute all the `.bats` files in the `tests` directory.
+
+To run a specific test file, you can pass the path to the file as an argument:
+```bash
+bats tests/some_test_file.bats
+```
+
+## Creating New Tests
+
+To create new tests, you should create a new file in the `tests` directory with a `.bats` extension. It is recommended to create a separate file for each function or group of related functions. For example, tests for the `ollama_generate` function should be in a file named `tests/ollama_generate.bats`.
+
+### Test File Structure
+
+A basic test file looks like this:
+
+```bash
+#!/usr/bin/env bats
+
+# Load the Ollama Bash Lib
+source ./ollama_bash_lib.sh
+
+# A basic test case
+@test "A descriptive name for your test" {
+  # Run a command or function
+  run some_function_to_test "with some arguments"
+
+  # Add assertions to check the output
+  [ "$status" -eq 0 ] # Check the exit status
+  [ "$output" = "expected output" ] # Check the output string
+}
+```
+
+### Writing Tests
+
+-   **Load the Library:** Make sure to source the `ollama_bash_lib.sh` at the beginning of your test file so that you can call the library functions.
+-   **Test Names:** Use descriptive names for your tests in the `@test` directive.
+-   **`run` command:** Use the `run` command to execute the function you want to test. This captures the `status` and `output` of the command.
+-   **Assertions:** Use assertions to check the results of your test. Bats provides special variables that you can use for assertions:
+    -   `$status`: The exit status of the command.
+    -   `$output`: The combined content of stdout and stderr from the command.
+    -   `$lines`: An array containing each line of the output.
+
+For more advanced testing techniques, please refer to the [official Bats documentation](https://bats-core.readthedocs.io/en/stable/).
