# QA Leveraging GenAI

description = '''
This tool leverages OpenAI's GPT-3.5-turbo model to automate two key aspects of quality assurance in software development: generating test cases and writing test scripts.

By inputting a functional use case, you can generate detailed test cases to ensure the quality of your software. 
You can also select your preferred testing framework, and the tool will generate test scripts based on the generated test cases
<hr>

howto = '''

## How to Use

**Test Case Generation**
Enter Functional usecase: Describe the functional use case for which you want to generate test cases. The more specific you are, the better the generated test cases will be.
Click on Generate Test Case button

**Test Script Generation**
Select a Test Framework: Choose the testing framework that you want the test scripts to be compatible with. Currently, you can select between Python's unittest and Java's JUnit frameworks.
---
## Results

- **Test Case**: This section will display the generated test cases based on the functional use case you provided. 

- **Test Script**: After choosing your preferred language and testing framework, this section will display the test scripts corresponding to the generated test cases.

notices = '''
**Notice**
This tool is produced by an LLM and therefore the outputs might not be perfect. Its best to review and edit the generated test cases and scripts as necessary.
