Nipactivity Catia Hot Link May 2026

Objective

Design a methodical, robust examination to evaluate whether and how the NiPActivity component (assumed to be a custom or third‑party activity class) integrates with CATIA (Dassault Systèmes CAD platform) under “hot” (high‑activity / high‑stress / runtime) conditions, producing actionable test procedures, metrics, and failure modes.

Assumptions (reasonable defaults)

Test plan overview

  1. Test goals

    • Verify functional correctness under heavy load.
    • Measure performance (latency, throughput, resource usage).
    • Detect memory leaks, resource exhaustion, thread-safety/race conditions.
    • Validate recovery and degradation behavior.
    • Capture reproducible failure signatures (logs, dumps).

  2. Test environments

    • Baseline: Minimal model, single instance of CATIA + NiPActivity.
    • Medium load: Moderate complexity models, several simultaneous user scripts.
    • Hot/stress: Very large assemblies, high-frequency event stream, multiple CATIA instances (local and remote), heavy I/O.
    • Isolation setups: Run NiPActivity outside CATIA (if possible) to isolate integration issues.
    • Hardware profiles: Low (8GB/4 cores), Recommended (16GB/8 cores), High (32–64GB/16+ cores).
    • Network: Local licensing vs. remote license server with simulated latency.

  3. Test types and specific cases A. Functional correctness under load

    • Run canonical workflows (open, edit, save, rebuild, export) repeatedly while NiPActivity processes events.
    • Verify outputs (files, parameters, feature tree) match expected results.
    • Test error-handling: force invalid inputs, corrupted models, missing resources.

    B. Concurrency / race condition tests

    • Launch parallel scripts that invoke NiPActivity APIs concurrently (N threads/processes; try N = 4, 8, 16).
    • Use stress harness to send events at increasing rates (e.g., 10/s → 100/s → 1000/s).
    • Add randomized delays and ordering permutations to expose races.

    C. Memory and leak detection

    • Long‑run test: continuous operation for 24–72 hours under heavy workload.
    • Monitor resident set size, private bytes, handle counts, GDI/USER objects.
    • Repeatedly open/close large assemblies and create/destroy activity instances.
    • Use tools: Windows Performance Monitor, VMMap, Process Explorer, or built-in memory profilers.

    D. CPU, IO, and latency profiling

    • Measure per-operation latency (mean, p50/p90/p99) for key API calls and user actions.
    • Measure throughput (operations per minute/hour) under increasing concurrency.
    • Profile CPU breakdown (NiPActivity vs CATIA vs OS overhead).
    • Monitor disk IO and page faults under large model loads.

    E. Stability under exceptional conditions

    • Simulate intermittent network (license) failures.
    • Inject faults: kill dependent threads/processes, restrict permissions, disk full.
    • Force garbage collection or memory pressure (if managed code).
    • Observe recovery: does NiPActivity reinitialize cleanly, or cause CATIA instability?

    F. Resource contention and external integrations

    • Test simultaneous access to shared resources (files, databases, network services).
    • Validate behavior with anti‑virus scanning enabled, or when files are locked.
    • Verify license checkout/release semantics under rapid start/stop.

    G. Scalability tests

    • Increase model size (parts, features) and measure performance scaling.
    • Run multiple CATIA sessions on same machine and across network to measure aggregate impact.

  4. Instrumentation and data collection

    • Logs: enable detailed NiPActivity logging (timestamp, thread id, correlation id, input args, errors). Use structured logging (JSON).
    • Traces: capture ETW/PerfView traces for Windows to correlate CPU and GC events.
    • Metrics: record latency histograms, throughput counters, resource gauges (CPU, RAM, handles).
    • Dumps: automatic crash and hung process dumps (on failure or on threshold breaches).
    • Repro harness: capture inputs/commands that reproduce a failure (scripts, model files, random seeds).

  5. Acceptance criteria / pass–fail thresholds (examples)

    • Functional: 100% of core workflows produce correct outputs in baseline and medium; ≥99% under hot conditions.
    • Latency: p90 latency < X ms for operation A; p99 < Y ms (set concrete numbers from baseline measurements).
    • Memory: no sustained growth > 5% of baseline per hour; handles/GDI stable.
    • Crashes: zero fatal crashes in 72‑hour hot test.
    • Recovery: component recovers within T seconds after transient failures; CATIA remains responsive.

  6. Failure modes to detect and actions

    • Memory leak: steadily increasing memory/handles → capture heap, identify allocation hot paths.
    • Deadlocks: threads waiting indefinitely → capture thread dumps, analyze call stacks and lock order.
    • High CPU spin loops: flame graphs → optimize hot functions.
    • File/DB contention: transient failures when file locked → implement retries with backoff and clear error propagation.
    • Licensing exhaustion: failed checkouts under parallel startup → implement pooling or queuing.

  7. Test automation and repeatability

    • Automate using scripted CATIA macros, Python VBScript, or dedicated test harness controlling instances.
    • Parameterize tests (model size, concurrency, event rate) and run in CI for regressions.
    • Store raw traces, logs, and artifacts with test metadata (build, OS, hardware) for triage.

  8. Prioritization and roadmap

    • Start with targeted unit/integration tests to catch obvious concurrency and leak issues.
    • Move to medium soak tests (8–24 hours) to detect slower leaks.
    • Run full “hot” stress (48–72 hours) with maximum concurrency and large models.
    • After fixes, run regression stress tests in CI nightly.

  9. Useful tools and commands (Windows-focused)

    • Performance monitoring: Windows Performance Monitor (perfmon), PerfView, Process Explorer.
    • Memory analysis: VMMap, WinDbg, procdump (for dumps).
    • Tracing: ETW/PerfView, Windows Event Log.
    • Load harness: custom scripting (PowerShell, Python), or third‑party load testers adapted to CATIA automation.
    • Logging: structured log files, central aggregator for offline analysis.
