Autify Nexus is equipped with an AI Agent that can be used in various situations, such as test case generation, scenario creation, and scenario maintenance. We will now go through each of these feature in details. ## Test case generation You can use the AI Agent to automatically generate test cases from an input text (eg. product specifications or ticket) given as plain text or a file. ### How to generate test cases To generate test cases, follow the steps below: 1. Open the **Scenarios** page, click the **Generate with AI** button, and select **Generate Test Cases** from the displayed dropdown menu. ![](https://cdn.document360.io/c040854c-2c75-49d0-98e1-43f462e8657e/Images/Documentation/スクリーンショット 2025-10-06 23.37.11.png?sv=2026-02-06&spr=https&st=2026-11-08T16%3A14%3A45Z&se=2026-11-08T17%3A14%3A45Z&sr=c&sp=r&sig=IHif5VGdYnnCk%2FwabDsJ44r5FexTc1LVKIzvLMn%2BcPE%3D) 2. In the AI Agent window, enter the specifications of the feature that you want to generate test cases for. - You can upload files such as **PDF** or **CSV** by clicking the paper clip icon ![](https://cdn.document360.io/c040854c-2c75-49d0-98e1-43f462e8657e/Images/Documentation/Screenshot%202025-10-27%20at%209.57.00.png?sv=2026-02-06&spr=https&st=2026-11-08T16%3A14%3A45Z&se=2026-11-08T17%3A14%3A45Z&sr=c&sp=r&sig=IHif5VGdYnnCk%2FwabDsJ44r5FexTc1LVKIzvLMn%2BcPE%3D) at the bottom of the window. (Check [here](/v1/docs/nexus-ai-agent#what-file-formats-are-supported-for-upload) for other supported file formats.) - You can also directly enter the requirements into the text area. - Example instruction for **Generate Test Cases:** *Generate only the happy path test cases from the user stories within the attached specification.* 3. Enter instructions for test case generation, and click the **Send** button (![](https://cdn.document360.io/c040854c-2c75-49d0-98e1-43f462e8657e/Images/Documentation/base64-converted-image-1787285231326.png?sv=2026-02-06&spr=https&st=2026-11-08T16%3A14%3A45Z&se=2026-11-08T17%3A14%3A45Z&sr=c&sp=r&sig=IHif5VGdYnnCk%2FwabDsJ44r5FexTc1LVKIzvLMn%2BcPE%3D)). 4. The AI Agent automatically generates the test cases and saves them as a CSV file in your Download folder. - The time required for generation will vary depending on the size and content of the uploaded file. 5. Open the downloaded CSV file and verify the generated content. - If the requirements are not met or if additional test cases are needed, you can re-enter instructions and regenerate them. - Sending a regeneration instruction will generate new test cases and save them as a separate CSV file. ## Scenario creation The AI Agent can automatically record each step of a scenario based on test cases or instructions in natural language. You can launch the AI Agent in the scenario creation screen by clicking **AI Agent** in the [recorder toolbar](/v1/docs/recorder-toolbar). Enter your test cases or test details and then start recording. ### Creating scenarios from test cases The AI Agent can record a scenario based on the test cases generated with the [Test case generation](/v1/docs/nexus-ai-agent#test-case-generation) feature. Just upload the CSV file generated at the previous step using the paper clip icon ![](https://cdn.document360.io/c040854c-2c75-49d0-98e1-43f462e8657e/Images/Documentation/Screenshot%202025-10-27%20at%209.57.00.png?sv=2026-02-06&spr=https&st=2026-11-08T16%3A14%3A45Z&se=2026-11-08T17%3A14%3A45Z&sr=c&sp=r&sig=IHif5VGdYnnCk%2FwabDsJ44r5FexTc1LVKIzvLMn%2BcPE%3D). > The CSV file generated by the Test case generation feature contains multiple test cases. > > If you want the AI Agent to create a scenario based on a selection of test cases, provide instructions that clearly identify the test cases inside the file. ### Creating scenarios with natural language instructions You can record a scenario just by describing what you want to test in natural language to the AI Agent. For example: *I want to confirm that when I click the lowest priced product on the product page and add it to the cart, that product is correctly added to the cart.* For more details, refer to the [Natural language step article](/v1/docs/natural-language-step). ## Scenario maintenance The AI Agent can analyze the cause of an error that occurred during test execution, and then suggest and apply a fix. Open the test result, click the **Fix with AI** button on the failed step, and launch the AI Agent. After the AI Agent applies the fix, re-execute the scenario to confirm the changes. ## Data Handling for Nexus AI Agent - The Nexus AI agent may retain some metadata necessary for system operation (e.g., generation event information) as logs, but the body or content of the input data is not saved. - Input data is sent along with the prompt to a third-party LLM (currently OpenAI) and then discarded. - [Enterprise privacy at OpenAI](https://openai.com/enterprise-privacy/) states that input and output data are never used for model training. However, the data is stored in OpenAI's data centers (in the US) for up to 30 days for abuse detection purposes, and unless abuse is suspected, it is automatically deleted without anyone at OpenAI accessing it. --- ### FAQ ### What file formats are supported for upload?
