| 1 | +# OpenClaw.NET Agent Testing Harness |
| 2 | + |
| 3 | +## Purpose |
| 4 | + |
| 5 | +The agent testing harness is a small scenario runner for OpenClaw.NET. It loads JSON scenario files, builds deterministic traces, evaluates those traces with explicit oracles, and writes run artifacts under `artifacts/testing/agent-scenarios/<run-id>/`. |
| 6 | + |
| 7 | +This is separate from `openclaw eval`, which evaluates model profiles through the gateway. The harness is for agent behavior contracts: tool choice, final answer constraints, approval behavior, safety boundaries, and trace evidence. |
| 8 | + |
| 9 | +## Why Scenario-Based Testing |
| 10 | + |
| 11 | +Agent behavior is not usefully tested by proving that a prompt executed. A scenario records the intended behavior before the run: |
| 12 | + |
| 13 | +- what user input is being tested |
| 14 | +- which tools must or must not be called |
| 15 | +- whether approval should be required |
| 16 | +- what the final answer must include or avoid |
| 17 | +- which reusable oracle types should judge the trace |
| 18 | + |
| 19 | +The MVP uses `scriptedTrace` for deterministic local runs. That keeps the first version fast, CI-friendly, and NativeAOT-friendly while leaving a clear seam for a real runtime or gateway runner. |
| 20 | + |
| 21 | +## Generated Tests Need Oracles |
| 22 | + |
| 23 | +AI-generated tests are drafts, not truth. A generated scenario is not meaningful until a human or trusted review process adds explicit expected behavior and oracle definitions. Shallow tests that only confirm execution should fail review and fail harness execution if they declare no oracles. |
| 24 | + |
| 25 | +## Scenario JSON |
| 26 | + |
| 27 | +Scenario files live in `tests/agent-scenarios/*.json` by default and use camelCase JSON. |
| 28 | + |
| 29 | +```json |
| 30 | +{ |
| 31 | + "id": "agent.tool.basic", |
| 32 | + "title": "Agent calls the expected read-only tool", |
| 33 | + "risk": "Medium", |
| 34 | + "type": "agent", |
| 35 | + "tags": ["tool-use", "regression"], |
| 36 | + "input": { |
| 37 | + "userMessage": "Look up demo information using the web search tool." |
| 38 | + }, |
| 39 | + "expected": { |
| 40 | + "mustCallTools": ["web_search"], |
| 41 | + "mustNotCallTools": ["shell", "write_file"], |
| 42 | + "finalAnswerContains": ["demo"], |
| 43 | + "maxToolCalls": 1, |
| 44 | + "requiresApproval": false |
| 45 | + }, |
| 46 | + "oracles": [ |
| 47 | + { "type": "tool-called", "tool": "web_search" }, |
| 48 | + { "type": "tool-not-called", "tool": "shell" }, |
| 49 | + { "type": "final-answer-contains", "value": "demo" }, |
| 50 | + { "type": "max-tool-calls", "limit": 1 }, |
| 51 | + { "type": "approval-not-required" }, |
| 52 | + { "type": "no-unsafe-tool" } |
| 53 | + ], |
| 54 | + "scriptedTrace": { |
| 55 | + "finalAnswer": "The demo information was found with the read-only search tool.", |
| 56 | + "status": "completed", |
| 57 | + "steps": [ |
| 58 | + { |
| 59 | + "kind": "toolCall", |
| 60 | + "toolName": "web_search", |
| 61 | + "argumentsJson": "{\"query\":\"demo information\"}" |
| 62 | + } |
| 63 | + ] |
| 64 | + } |
| 65 | +} |
| 66 | +``` |
| 67 | + |
| 68 | +`scriptedTrace` is the MVP runner input. It is intentionally separate from `expected` and `oracles` so the runner does not build traces from the assertions it is supposed to validate. |
| 69 | + |
| 70 | +## Oracle Types |
| 71 | + |
| 72 | +The default oracle registry is explicit and does not scan assemblies. |
| 73 | + |
| 74 | +| Type | Checks | |
| 75 | +| --- | --- | |
| 76 | +| `tool-called` | A named tool appears as a `toolCall` trace step. | |
| 77 | +| `tool-not-called` | A named forbidden tool does not appear as a `toolCall` trace step. | |
| 78 | +| `max-tool-calls` | Total `toolCall` steps are less than or equal to the configured limit. | |
| 79 | +| `final-answer-contains` | The final answer contains required text. | |
| 80 | +| `final-answer-not-contains` | The final answer avoids forbidden text. | |
| 81 | +| `approval-required` | The trace contains an `approvalRequest`, optionally for a specific tool. | |
| 82 | +| `approval-not-required` | The trace contains no approval request. | |
| 83 | +| `no-unsafe-tool` | Unsafe tools are not called without an approval request. | |
| 84 | + |
| 85 | +Default unsafe tools are repo-native names: `shell`, `write_file`, `code_exec`, `git`, `home_assistant_write`, `mqtt_publish`, and `notion_write`. A scenario can add comma-separated names in `metadata.unsafeTools`, and a `no-unsafe-tool` oracle can include a `tools` array. |
| 86 | + |
| 87 | +## CLI Usage |
| 88 | + |
| 89 | +From a source checkout: |
| 90 | + |
| 91 | +```bash |
| 92 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test init |
| 93 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test gates |
| 94 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test run |
| 95 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test run --fail-on any |
| 96 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test report |
| 97 | +``` |
| 98 | + |
| 99 | +Installed CLI form: |
| 100 | + |
| 101 | +```bash |
| 102 | +openclaw test init |
| 103 | +openclaw test gates |
| 104 | +openclaw test run |
| 105 | +openclaw test report |
| 106 | +``` |
| 107 | + |
| 108 | +`test run` returns non-zero when high-risk or critical scenarios fail. Use `--fail-on any` when CI should fail on any scenario failure. |
| 109 | + |
| 110 | +## xUnit Usage |
| 111 | + |
| 112 | +The repository keeps xUnit coverage in `src/OpenClaw.Tests`. Tests can load scenarios and execute the harness directly: |
| 113 | + |
| 114 | +```csharp |
| 115 | +var scenarios = await new JsonScenarioLoader().LoadAsync("tests/agent-scenarios"); |
| 116 | +var report = await new ScenarioHarness().RunAsync(scenarios); |
| 117 | + |
| 118 | +Assert.Equal(0, report.Summary.Failed); |
| 119 | +``` |
| 120 | + |
| 121 | +Use this for deterministic scenario checks, oracle unit tests, and CLI smoke coverage. |
| 122 | + |
| 123 | +## CI Example |
| 124 | + |
| 125 | +The harness is cheap and deterministic, so it can be added after the normal build/test steps: |
| 126 | + |
| 127 | +```bash |
| 128 | +dotnet restore OpenClaw.Net.slnx |
| 129 | +dotnet build OpenClaw.Net.slnx -c Release --no-restore |
| 130 | +dotnet test src/OpenClaw.Tests/OpenClaw.Tests.csproj -c Release --no-build |
| 131 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test gates |
| 132 | +dotnet run --project src/OpenClaw.Cli/OpenClaw.Cli.csproj -- test run --fail-on any |
| 133 | +``` |
| 134 | + |
| 135 | +Do not commit generated files from `artifacts/testing/agent-scenarios/`. |
| 136 | + |
| 137 | +## Adding Oracle Types |
| 138 | + |
| 139 | +Add a small `IScenarioOracle` implementation in `src/OpenClaw.Testing`, register it by string key in `ScenarioOracleRegistry`, and add focused xUnit pass/fail coverage. Keep the oracle deterministic and based on `AgentRunTrace`, not live runtime state. |
| 140 | + |
| 141 | +## Future Integration |
| 142 | + |
| 143 | +The MVP runner is `ScriptedScenarioRunner`. Future adapters should implement `IScenarioRunner` without changing scenario files: |
| 144 | + |
| 145 | +- an `AgentRuntime` adapter that captures tool calls and final answers from the native runtime |
| 146 | +- a gateway adapter that drives HTTP/WebSocket surfaces and converts events into `TraceStep` |
| 147 | +- a plugin bridge adapter for compatibility scenarios |
| 148 | +- an approval policy adapter that records approval requests and decisions |
| 149 | +- a trace replay adapter that re-evaluates stored traces as regression evidence |
| 150 | + |
| 151 | +Keep adapters explicit. Avoid runtime assembly scanning and reflection-heavy discovery paths. |
| 152 | + |
| 153 | +## Known Limitations |
| 154 | + |
| 155 | +- The MVP does not execute the real agent runtime by default. |
| 156 | +- `scriptedTrace` is deterministic evidence for oracle and gate behavior, not proof of provider behavior. |
| 157 | +- Oracles inspect trace shape and final answer strings; they do not judge semantic quality. |
| 158 | +- No visual UI, scenario generation, plugin certification, or AgentQi Studio workflow is included. |
