asserting-node-state-and-text

A guide to checking UI state and displayed text in Jetpack Compose tests. It explains the framework’s built-in checks for presence, visibility, enabled status, selection, focus, switches, checkboxes, and text.

In plain words
What is it for?
Use it to check buttons, switches, checkboxes, text, collections of nodes, and custom semantic properties.
Why use it?
It helps you verify UI through the test framework instead of reading internal node data directly, and clarifies the difference between existing and visible.

Token cost

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.

Security

Grade A, and why

asserting-node-state-and-text 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 3d 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.

Asserting Node State and Text — Verify Through the Framework, Not Through fetchSemanticsNode

Once a finder resolves to a SemanticsNodeInteraction, the next step is asserting it. Compose ships a typed assertion for almost every semantic property; the generic assert(matcher) covers the rest. This skill picks the right assertion, distinguishes "exists" from "displayed", and shows when boolean predicates belong inside waitUntil.

When to use this skill

  • The developer wants to verify a Switch is on, a Checkbox is unchecked, a Button is enabled, a Text equals an expected string.
  • The developer asks about assertIsDisplayed vs assertExists (one verifies on-screen, the other verifies presence in the tree).
  • The developer needs a custom assertion via assert(matcher) for a property without a typed extension.
  • The developer wants to verify a collection: "exactly 3 items", "at least one is selected", "all are enabled".
  • A test compares node.config[...] directly instead of using a typed assertion.

When NOT to use this skill

  • The right node cannot be located — see ../../finders/finding-nodes-by-tag-text-content/SKILL.md.
  • The assertion is geometric (width, height, position) — see ./asserting-bounds-and-dimensions/SKILL.md.
  • The check needs a custom SemanticsMatcher — see ../../finders/composing-semantics-matchers/SKILL.md.
  • The state changes asynchronously and the assertion is timing-sensitive — see ../../synchronization/synchronizing-with-idle/SKILL.md.

Prerequisites

  • A working ComposeTestRule / ComposeUiTest. See ../../setup/configuring-test-dependencies/SKILL.md.
  • The node has been located through onNode* / onAllNodes* / a navigator.
  • For assertIsDisplayed semantics, the node must be composed AND placed AND at least partially on-screen post-clip (Assertions.kt:30-39).

Workflow

  • 1. Pick by question type. Map the developer's question to one assertion call. Every API listed is in commonMain/.../Assertions.kt unless noted.

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.

asserting-node-state-and-text is a skill published in the GitHub repository skydoves/android-testing-skills (313 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 220 tokens to every session and 3,634 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
