What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.01637 |
| Opus 5.5 | $0.00022 | $0.00655 |
| Sonnet 5.5 | $0.00011 | $0.00327 |
| Haiku 4.5 | $0.00005 | $0.00164 |
Grade A, and why
compose-ui-testing-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to compose-ui-testing-patterns — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Compose: UI testing patterns
Core principle
Test the smallest UI contract that proves the behavior. Prefer plain state-driven UI tests with callbacks. Add integration only when lifecycle, navigation, DI, or platform behavior is the thing under test.
Test target choice
| What you need to prove | Test shape |
|---|---|
| Text, button, loading/error branch, conditional content | Plain UI Compose test |
| Callback wiring from click/input | Plain UI Compose test |
| Focus navigation or keyboard behavior | Compose test with key input |
| Visual layout, clipping, elevation, typography, image composition | Screenshot test |
| State holder updates UI correctly | State holder/unit test plus one wiring smoke test |
| Hover, pressed, focused, dragged interaction state | Plain UI test with MutableInteractionSource |
| Navigation, lifecycle, DI integration | Integration test |
Prefer plain UI tests
If the screen has a state holder/UI split, test the plain UI composable:
composeTestRule.setContent {
ProfileScreen(
state = ProfileUiState(name = "Ada", canSave = true),
onNameChange = {},
onSaveClick = { saved = true },
onBackClick = {},
)
}
composeTestRule.onNodeWithText("Ada").assertIsDisplayed()
composeTestRule.onNodeWithText("Save").performClick()
assertThat(saved).isTrue()
This avoids constructing ViewModels, components, repositories, navigation, and dependency graphs for layout behavior.
Semantics first
Assert semantics when behavior is semantic:
- Text exists:
onNodeWithText. - Button is enabled/disabled:
assertIsEnabled,assertIsNotEnabled. - Content is selected/focused/toggled: use semantics assertions.
- Content is absent:
assertDoesNotExist.
Use test tags for nodes that have no stable user-visible text or where multiple nodes share text. Do not use tags as the first choice for all assertions; user-visible semantics are usually stronger.
Callback testing
Use simple counters or captured values:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

compose-ui-testing-patterns is a skill published in the GitHub repository costular/Minitask (12 stars, last pushed 6d ago), licensed Apache-2.0. It adds 54 tokens to every session and 1,637 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to compose-ui-testing-patterns, differing in 0 lines, and is treated as a copy.
