# Test Count & Typologies

## Typologies

| Typology              | What it covers                                     |
| --------------------- | -------------------------------------------------- |
| **Nominal**           | Happy path — expected, successful behaviour        |
| **Boundary / Limits** | Edge values: minimum, maximum, just-outside-bounds |
| **Equivalence**       | Representative partitions                          |
| **Negative**          | Invalid input, error handling, unexpected states   |

TestForge runs one LLM call per selected typology in parallel — a failed pass is non-blocking.

## Simple mode (default)

One global slider: **total number of tests (2–32)**. Distribution is proportional and shown live in pills below the slider:

```text theme={null}
3 Nominal · 4 Boundary · 2 Equivalence · 2 Negative
```

## Advanced mode

Click **Customise per typology** to set an individual slider for each selected typology.

* Range: **1–8 tests per typology**
* Maximum total: **32 tests**
* Running total displayed in real time

Click **Back to simple mode** to return. Your advanced configuration is preserved.

## Persisted preferences

Both the mode (simple/advanced) and the values are **saved to your ADO user account** (`test-count-config-v1`). They persist across sessions and browser reloads.

<Tip>
  A good starting point: **2 Nominal · 3 Boundary · 2 Equivalence · 2 Negative = 9 tests**. This covers the critical paths without creating noise.

## Why we cap at 32

Quality over quantity. A well-scoped user story (INVEST: Small) typically warrants 5–12 test cases. Beyond that, cases tend to be redundant — they pollute your ADO suite and increase maintenance cost without improving coverage.
