Ringkasan

Write unit and E2E tests for Grafana frontend code (React/TypeScript, any package or feature area) to the conventions this repo expects. Use when adding, backfilling, or reviewing frontend tests; when a test only asserts "it rendered" or "it's defined"; when reviewing AI-generated tests for slop; or when a frontend test is flaky. For visualization panels and grafana-ui viz components specifically, also load the `panel-testing-strategy` skill.

Frontend testing strategy

Write tests for Grafana frontend code that pass review on the first pass. Goals: assert concrete behavior, not existence; keep test descriptions honest; verify the test actually exercises the target code path; and stabilize the known flake classes. Several codeowner paths are opted into the gating check-frontend-test-coverage.yml check, so coverage that drops fails CI.

Resolve the target

Interpret the argument to decide scope:

A file path → test that file (create or extend its co-located *.test.ts(x)).
A directory / component / module name → the source files under it lacking meaningful coverage.
"current file" / no path but a file is open → the open file.
No argument → ask which file/area; don't blanket-generate.

Prefer extending an existing co-located test file over adding a new one. Match the surrounding test file's imports and idiom.

Principle 1 — Where each test fits: the (inverted) testing diamond

Testing model, top to bottom:

E2E (pinnacle) — validate the system via real user flows; powerful but slow, so keep it targeted and few.
Unit (base) — cheap, plentiful specs documenting behavior for logic/utils.
Static analysis (foundation) — lint + strong TypeScript interfaces.

Pick the layer that matches the job: logic/IO → unit; how pieces fit together → integration/visual; a key user journey → E2E. Favour speed and feedback — unit tests are cheap, so make them small and plentiful; reserve the expensive layers for what only they can cover.

Principle 2 — Assert real behavior, not existence

This is the bar reviewers hold every test to, at every layer. They reject tests that only prove a function ran. Never land these as the whole test:

expect(result).toBeDefined(); // ❌ proves nothing about correctness
expect(result).toBeInstanceOf(Foo); // ❌ (unless the type itself is the contract)
expect(() => fn(input)).not.toThrow(); // ❌ "didn't crash" is not a behavior
expect(result).toHaveLength(input.length); // ❌ if it just mirrors the input

Instead assert the concrete computed value, so a failure points at the real bug:

// diffperc: 10 -> 20 is a +100% change
const results = getDisplayValuesForCalcs(/* … */);
expect(results[0].numeric).toBe(100); // ✅ assert the math
expect(results[0].text).toBe('100%'); // (formatting is secondary)

If the function mostly delegates, assert the delegation with exact arguments (see Step 2).

Expected values are literals, not recomputations. Never derive the expected side by calling the code under test, a collaborator it calls internally, or by re-typing the production formula — the test then passes whenever the code and the expectation share the same bug, and comparing a value to itself asserts nothing at all. Freeze the expected value as a literal, computed once by hand or captured from a known-good run:

// ❌ circular: `expected` is produced the same way the code produces its result
const expected = theme.visualization.getColorByName('red');
expect(dim.value()).toBe(expected);
// ❌ re-derives the production formula — a bug in the formula is copied into `expected`
const expected = TABLE.CELL_PADDING * 2 + theme.typography.fontSize * theme.typography.body.lineHeight;
expect(getDefaultRowHeight(theme, [])).toBe(expected);

// ✅ frozen literals — a change in the resolver or the formula now fails the test
expect(dim.value()).toBe('#F2495C');
expect(getDefaultRowHeight(theme, [])).toBe(34);

For values awkward to write by hand (projected coordinates, hashes), assert an independent readback rather than re-running the same path — e.g. project lng/lat, read it back in WGS84, and compare to the literal input — or freeze it with toMatchInlineSnapshot.

Prove the assertion has teeth. Before landing, mutate the asserted value (or the source it derives from) and confirm the test goes red. A test that stays green — because its expectation tracks the code, or checks a value against itself — is a tautology dressed as coverage. Make this a habit, not just the final Verify step.

Principle 3 — Authoring with AI: no slop tests

This skill exists so AI-proposed tests meet the bar above. The failure mode to avoid is the slop test:

Unfocused — a wide blast of assertions that doesn't preserve the intent of the code under test.
Verbose — unnecessary steps/mocks for a simple goal; brittle to implementation changes, and can silently mask real regressions.
Limiting — so many, or so coupled to implementation, that a later refactor breaks them without telling you whether behavior actually broke. (Unreadable DOM snapshot tests are the classic example — never add them.)

Review AI output thoroughly before opening a PR; expect to amend it for readability/maintainability. If reviewing the AI output costs more than writing the test by hand, write it by hand. A test is a specification a teammate — and future-you — must read easily; value refactoring for readability over a raw coverage percentage.

Principle 4 — Do not simply update failing tests to pass after changing behaviour, or adding a feature

When a test fails after updating functionality, behaviour or features, this is a warning that a regression was caused. Tests are meant as a safety net to catch regressions, and a failing test isn't broken -- its doing its job.

Net new functionality requires net new tests. Existing tests should be treated as a spec, and if you cause a test to fail -- STOP -- and analyze why that test fails, only after thorough analysis based on tracing real code should an existing test ever be updated.

Step 1 — Name the test for exactly what it asserts

The it(...) string is triage documentation — a reviewer reads it first when a test fails, before opening the body. Make it behavior-specific, and keep it equivalent to the assertion:

// ❌ vague, and doesn't say what "works" means
it('handles the update', () => { … });

// ✅ says exactly what is asserted
it('sets the field to disabled when the parent form is read-only', () => {
  expect(getByRole('textbox')).toBeDisabled();
});

Use it.each with $name / $desc interpolation for enumerable variants so each row self-labels. Delete duplicate cases — if two tests exercise the same path, keep one.

Prefer deletion over inflation. When an assertion only restates what a stronger assertion in the same test already covers, keep the stronger and delete the other. Removing redundant coverage is a legitimate, reviewable improvement: a smaller honest test beats a padded one. Before deleting, confirm the behavior is still covered by a sibling assertion or test.

Step 2 — Verify the test reaches the target branch

Set the gates. e.g. a code path that only runs when a specific option/flag is set — omit it and you test the plain path and cover nothing. Set every precondition the branch requires.
Assert collaboration precisely when you deliberately don't want to test a collaborator — mock it and verify it's called with exact args / counts, not just that output exists:

const guess = jest.spyOn(mod, 'guessFieldTypes');
processFrames([frameA, frameB]);
expect(guess).toHaveBeenCalledTimes(2); // once per frame — use ≥2 frames
expect(getColor.mock.calls.map((c) => c[1])).toEqual([0, 2]); // skipped null at idx 1
guess.mockRestore();

Avoid loose assertions that pass for the wrong reason: no toMatch(/50/) where the exact value is knowable; no toBeGreaterThanOrEqual where the code guarantees a strict change (use toBeGreaterThan). Confine any external-interface cast to one helper rather than sprinkling @ts-expect-error.

To type a mocked function or module, use jest.mocked(fn) — never fn as jest.MockedFunction<typeof fn> (or as jest.Mocked<…>). jest.mocked is the type-safe, less noisy repo convention and gives typed access to .mock / .mockReturnValue:

import { measureText } from '@grafana/ui';
jest.mock('@grafana/ui', () => ({ ...jest.requireActual('@grafana/ui'), measureText: jest.fn() }));

const measureTextMock = jest.mocked(measureText); // ✅ not `measureText as jest.MockedFunction<…>`
measureTextMock.mockReturnValue({ width: 100 } as TextMetrics);
expect(measureTextMock).toHaveBeenCalledWith('label', 12);

Never mock @grafana/runtime/internal to fake a feature flag. It bypasses the real OpenFeature/flag-client wiring and drifts from how flags actually resolve at runtime:

// ❌ don't
jest.mock('@grafana/runtime/internal', () => ({
  ...jest.requireActual('@grafana/runtime/internal'),
  getFeatureFlagClient: () => ({ getBooleanValue: () => true }),
}));

Use setTestFlags from @grafana/test-utils/unstable instead — it drives the real client:

import { FlagKeys } from '@grafana/runtime/internal';
import { setTestFlags } from '@grafana/test-utils/unstable';

beforeAll(() => {
  setTestFlags({ [FlagKeys.PluginsUseMTPlugins]: true });
});

afterAll(() => {
  setTestFlags({});
});

For classic featuremgmt toggles (not OpenFeature flags), use testWithFeatureToggles (config.featureToggles) instead of mocking @grafana/runtime.

Step 3 — Don't test what shouldn't exist

Skip modules slated for deletion. Adding tests to deprecated code signals it's load-bearing and obstructs its removal. If unsure, ask.
Deferring comprehensiveness to a follow-up PR is acceptable — leave an explicit note rather than shipping a shallow test that looks complete.

Anti-flake rules

Each rule maps to a real stabilization; global Playwright config retries once in CI only. Avoid → Do:

Broad locators. Avoid page.locator('.some-widget') when it also matches previews/ thumbnails elsewhere on the page. Do scope to the owning container: getByGrafanaSelector(Panels.Panel.content).locator('.some-widget').
Reading DOM text + regex while state settles. Avoid textContent().match(/(\d+) selected/) on a virtualized/animating list. Do assert the container is visible, read a stable source (e.g. the checkbox input), capture "before" once via a shared helper. (#121757)
JSDOM modal / elementFromPoint hacks (double-click, drag simulation). Do reach the state via a deterministic path (context-menu → "Edit" menuitem) then waitFor the control. (#127124)
.fill() on contenteditable / CodeMirror. Do click() to focus, then pressSequentially(); target fields by getByLabel. (#127979)
Timeout flake may be a real async race. An unsubscribed/uncleared async load can overwrite fresh UI with a stale response. Fix the product (cancel in-flight work, clear stale UI on context change) and wait for new content before interacting. (geomap #127100)
Not waiting for React state flush. Wrap post-interaction assertions in waitFor. A waitFor callback must throw to retry, so it needs expect, not a bare boolean. (#124994)
Long multi-step E2E specs. Mark test.slow() and add explicit load gates instead of leaning on default timeouts. (#121757)

Testing HTML5 canvas / uPlot-based visualizations, or writing panel accessibility and interaction-snapshot E2E tests, has its own harness and additional canvas-specific anti-flake rules — see the panel-testing-strategy skill.

compare to the literal input — or freeze it with `toMatchInlineSnapshot`.

**Prove the assertion has teeth.** Before landing, mutate the asserted value (or the source it

Use `it.each` with `$name` / `$desc` interpolation for enumerable variants so each row
self-labels. Delete duplicate cases — if two tests exercise the same path, keep one.

**Prefer deletion over inflation.** When an assertion only restates what a stronger assertion in

```

**Never mock `@grafana/runtime/internal` to fake a feature flag.** It bypasses the real
OpenFeature/flag-client wiring and drifts from how flags actually resolve at runtime:

```ts
// ❌ don't
jest.mock('@grafana/runtime/internal', () => ({

}));
```

Use `setTestFlags` from `@grafana/test-utils/unstable` instead — it drives the real client:

```

For classic `featuremgmt` toggles (not OpenFeature flags), use `testWithFeatureToggles`
(`config.featureToggles`) instead of mocking `@grafana/runtime`.
