# Blackbox Tests

## Positive Scenarios

### FT-P-01: [Scenario Name]

**Summary**: [One sentence: what black-box use case this validates]
**Traces to**: AC-[ID], AC-[ID]
**Category**: [which AC category — e.g., Position Accuracy, Image Processing, etc.]

**Preconditions**:
- [System state required before test]

**Input data**: [reference to specific data set or file from test-data.md]

**Steps**:

| Step | Consumer Action | Expected System Response |
|------|----------------|------------------------|
| 1 | [call / send / provide input] | [response / event / output] |
| 2 | [call / send / provide input] | [response / event / output] |

**Expected outcome**: [specific, measurable result]
**Max execution time**: [e.g., 10s]

## Negative Scenarios

### FT-N-01: [Scenario Name]

**Summary**: [One sentence: what invalid/edge input this tests]
**Traces to**: AC-[ID] (negative case), RESTRICT-[ID]
**Category**: [which AC/restriction category]

**Preconditions**:
- [System state required before test]

**Input data**: [reference to specific invalid data or edge case]

**Steps**:

| Step | Consumer Action | Expected System Response |
|------|----------------|------------------------|
| 1 | [provide invalid input / trigger edge case] | [error response / graceful degradation / fallback behavior] |

**Expected outcome**: [system rejects gracefully / falls back to X / returns error Y]
**Max execution time**: [e.g., 5s]

Guidance Notes

• Blackbox tests should typically trace to at least one acceptance criterion or restriction. Tests without a trace are allowed but should have a clear justification.
• Positive scenarios validate the system does what it should.
• Negative scenarios validate the system rejects or handles gracefully what it shouldn't accept.
• Expected outcomes must be specific and measurable — not "works correctly" but "returns position within 50m of ground truth."
• Input data references should point to specific entries in test-data.md.
