Requirements and Design Document Drafting for Performance Testing and Capacity Assessment: Multi-turn Dialogue and Prompt Engineering

What data for this category looks like

Performance testing and capacity assessment data primarily comes from stress testing platforms, APM monitoring systems, database slow logs, and production traffic baselines. Daily produced documents include stress testing plans, capacity assessment reports, stress testing data records, and optimization suggestion sheets. Common fields include throughput (times/second), average latency (milliseconds), resource utilization (%), peak concurrent count, and others. Data update frequency is monthly or when major versions are released. Document structures typically include modules such as testing objectives, environment configurations, test scripts, indicator thresholds, and conclusions.

What constraints do these characteristics impose for multi-turn dialogue and prompt engineering

Multi-source data requirements mean multi-turn dialogue must integrate information from different channels in sequence. Prompts should guide summarization of basic stress testing data first, then supplement APM bottleneck indicators and slow log details, to avoid information chaos. The non-fixed data update frequency requires prompts to support dynamic adjustment of data ranges, adapting to testing needs for different versions or cycles. The large number of category-specific fields requires prompts to clearly specify which indicators to extract, preventing generated documents from missing core performance parameters. The most time-consuming links of stress testing model design and bottleneck identification require multi-turn dialogue to focus on this scenario, gradually refining the content of requirements and design documents.

How to configure settings

This configuration applies to FastGPT v4.17.0.

Configuration ItemRecommended ApproachRationale
chatIdBind to the test session ID of the current projectEnable context continuity for multi-turn dialogue, avoid retyping historical data
messagesInclude system prompts + summaries of the most recent 3 stress testing data setsEnsure dialogue proceeds based on existing performance testing information, reduce redundant input
variablesPreset lists of throughput, latency, and resource utilization fieldsForce generated documents to include category-specific core indicators
Maximum context8000–12000 tokensAdapt to integration needs for multi-source documents such as stress testing plans and capacity reports
Single history referenceFirst 8 dialogue recordsFilter redundant information, focus on drafting current requirements and design documents

Three common mistakes

  • Symptom: Generated document fragments have inconsistent logic, with conflicting values for the same indicator. Cause: chatId is not bound, multi-turn dialogue does not maintain context, and historical data is reset on each call.
  • Symptom: Generated stress testing plans do not include core performance indicators such as throughput and latency. Cause: Category-specific fields are not bound via variables, and prompts do not explicitly require extraction of related data.
  • Symptom: Outputs from multiple AI dialogue nodes executed in batch are mixed, and cannot be matched to specific test scenarios. Cause: Each dialogue node is not configured with an independent chatId, causing context to be overwritten across nodes.

How to confirm configuration is complete

  • Initiate a dialogue for test data summary, then follow up with a question about bottleneck analysis. Check if the dialogue continues the previous discussion to confirm chatId binding is active.
  • Generate a preliminary stress testing plan document. Check if the document includes preset fields such as throughput and latency to confirm variables binding is correct.
  • Start two independent test sessions, each sending the same prompt request. Check if outputs match the context of their respective sessions to confirm context isolation works properly.
  • View dialogue logs to confirm the number of referenced historical messages matches the set single history reference limit, confirming redundant information has been filtered.
