Prompt的重要性

Prompt在AI的应用中扮演着至关重要的角色。它作为AI理解和执行任务的基础，其准确性和清晰度将直接影响AI生成的结果。AI通过对Prompt的解析，理解关键词及其语义关系，从而精准地执行我们的指令。

为了演示如何使用DeepSeek生成接口测试用例，我们首先编写一个简单的Prompt：

根据提供的接口信息，生成接口测试用例，并以json格式返回。json格式需包含请求体、请求头。接口信息如下：{ "API": "/payment", "method": "POST", "params": { "user_id": {"type": "int", "required": true, "min": 1000, "max": 9999}, "amount": {"type": "float", "required": true, "min": 0.01, "max": 10000.00}, "currency": {"type": "enum", "values": ["USD", "CNY", "EUR"]}, "timestamp": {"type": "timestamp", "format": "ISO8601"} } }

调用模型

完成Prompt编写后，我们将其输入DeepSeek模型，观察其返回结果：

    "name":"valid_request_all_parameters",
    "method":"POST",
    "path":"/payment",

    "expected_validation":["timestamp must be in ISO8601 format"]
  }]
}

从返回结果来看，DeepSeek成功生成了我们期望的测试用例。这些测试用例可以直接用于编写接口测试脚本，我们只需将DeepSeek返回的结果传递给测试脚本即可。当然，根据实际需求，预期结果可能需要进行微调，但接口返回的状态码通常是可以直接使用的。此外，我们还可以在Prompt中预先定义接口返回的枚举值，以便DeepSeek生成更精确的测试用例。
