개요

Write unit and E2E tests for Grafana visualization panels and viz utilities to the conventions this repo expects. Use when adding, backfilling, or reviewing tests for panels (barchart, timeseries, table, xychart, heatmap, canvas, etc.), grafana-ui viz components (Table, uPlot, VizLegend, VizTooltip), or grafana-data viz utils; when a panel test only asserts "it rendered" or "it's defined"; when reviewing AI-generated panel tests for slop; or when a canvas/rendering test is flaky.

Panel testing strategy

This skill builds on frontend-testing-strategy — read that first for the general principles every Grafana frontend test is held to (the inverted testing diamond, asserting real behavior instead of existence, avoiding AI slop, verifying a test reaches its target branch, generic anti-flake rules, and the SDLC-phase gating). This skill covers what's specific to visualization code on top of that: data-frame/panel-prop builders, the canvas draw-call snapshot harness, panel accessibility and interaction-snapshot E2E, and canvas/uPlot-specific anti-flake rules. The visualization codeowner paths are opted into the gating check-frontend-test-coverage.yml check, so coverage that drops fails CI.

Step 1 — Set up data with the repo's builders

Build data frames with the @grafana/data builders — pick one and don't mix toDataFrame and createDataFrame in the same file:

import { createDataFrame, toDataFrame, arrayToDataFrame, FieldType, LoadingState } from '@grafana/data';

Use a single canonical builder per file with a Partial<> overrides object, rather than bespoke frames per test:

function makeFrame(overrides: Partial<Options> = {}) {
  /* … */
}

To render a panel component, use the shared panel-props builder instead of hand-rolling props:

import { getPanelProps } from '../test-utils'; // public/app/plugins/panel/test-utils.ts
render(<BarChartPanel {...getPanelProps(defaultOptions, { fieldConfig })} />);

Gotcha — field config. A panel unit test must call applyFieldOverrides itself with a createFieldConfigRegistry; the panel framework normally does this, so without it your custom fieldConfig.custom never reaches the render and every case looks identical.

Gotcha — type inference. If you're testing guessFieldTypes (or any inference), feed untyped raw fields (as unknown as DataFrameDTO). createDataFrame pre-sets type, so the function under test becomes a no-op and the test gives false confidence.

Step 2 — HTML5 canvas / rendering panels: use the draw-call snapshot harness

Panels that draw to canvas (timeseries, heatmap, xychart, timeline, piechart, sparkline) are tested by capturing the ctx draw-call stream, not by pixel-diffing. Follow the established harness:

// In the harness (public/app/plugins/panel/timeseries/TimeSeriesPanel.canvasTestUtils.tsx):
import {
  applyDefaultUPlotAxisMeasureTextMock,
  installCanvasPath2DShim,
  removeCanvasTransforms,
} from '@grafana/test-utils/canvas';

// In each *.canvas.test.tsx, mock grafana-ui's text measurement so layout is deterministic:
jest.mock('@grafana/ui/src/utils/measureText', () =>
  require('@grafana/test-utils/canvas').createGrafanaUiMeasureTextJestMock(() =>
    require('./TimeSeriesPanel.canvasTestUtils').getUPlotInstance()
  )
);

Split suites by concern: *.lines.canvas.test.tsx, *.fills.…, *.annotations.…, *.axisPlacement.…, *.axisRange.… — each a focused it.each of cases.
Assert with the custom matcher: expect(events).toMatchCanvasSnapshot(context, { width, height }).
Keep it deterministic (this is where flake comes from): fixed width/height, UTC timestamps (Date.UTC(...), timeZone: 'utc'), and wait for the renderer to be ready before asserting — await waitFor(() => expect(uPlotInstance?.status).toBe(1)) (a waitFor callback must throw to retry, so it needs expect, not a bare boolean).

Step 3 — E2E for interaction, accessibility, and interaction snapshots

The DataViz strategy is unit-first. Reserve Playwright for cross-component interaction and per-panel smoke coverage. When you do write E2E:

Add the selector to the versioned @grafana/e2e-selectors package first, wire data-testid into the JSX, then query it (use the add-e2e-selectors skill).
Query by selector, never brittle CSS — in E2E dashboardPage.getByGrafanaSelector(...), in unit screen.getByTestId(selectors.components...).

import { test, expect } from '@grafana/plugin-e2e';

test.describe('Panels test: BarChart render', { tag: ['@panels', '@barchart'] }, () => {
  test('renders without error', async ({ gotoDashboardPage, selectors }) => {
    const page = await gotoDashboardPage({ uid: DASHBOARD_UID }); // provisioned devenv dashboard
    await expect(page.getByGrafanaSelector(selectors.components.Panels.Panel.headerCornerInfo('error'))).toBeHidden();
  });
});

Every panel must have an E2E accessibility test. Use the scanForA11yViolations fixture and the toHaveNoA11yViolations() matcher, in a describe/test tagged @a11y. Load the panel, wait for it to actually render (assert the panel title and the chart element are visible — an empty panel trivially passes), then scan:

test.describe('a11y', { tag: ['@a11y'] }, () => {
  test('run a11y report', async ({ gotoDashboardPage, scanForA11yViolations, selectors, page }) => {
    const dashboardPage = await gotoDashboardPage({
      uid: DASHBOARD_UID,
      queryParams: new URLSearchParams({ viewPanel: 'panel-4' }),
    });
    await expect(dashboardPage.getByGrafanaSelector(selectors.components.Panels.Panel.title('…'))).toBeVisible();
    await expect(page.locator('.uplot')).toBeVisible(); // panel has drawn

    const report = await scanForA11yViolations({
      options: { runOnly: ['wcag2a', 'wcag2aa', 'wcag21a', 'wcag21aa', 'best-practice'] },
    });
    expect(report).toHaveNoA11yViolations();
  });
});

Only pass ignoredRules for a documented, tracked pre-existing violation — add a @todo with the tracking issue rather than silently ignoring (e.g. page-has-heading-one, region, color-contrast are common app-shell noise, not panel bugs).
Exemplars: e2e-playwright/panels-suite/{histogram,xychart,table-nested,table-kitchenSink}.spec.ts, and keyboard-a11y in e2e-playwright/various-suite/panel-presets.spec.ts.

Interaction snapshots — cover a variety of states, not just first render

A panel's accessibility and structure change as the user interacts. For each panel, drive a variety of interaction states and snapshot the resulting accessibility tree with toMatchAriaSnapshot, re-running the a11y scan in the states that matter. Typical states per panel type: default render, hover / tooltip open, legend item toggled, sort / filter applied (table), series selected, panel edit mode, and empty / no-data.

const panel = dashboardPage.getByGrafanaSelector(selectors.components.Panels.Panel.content);
await expect(panel).toMatchAriaSnapshot(); // baseline structure
await panel.locator('.uplot').hover({ position: { x: 120, y: 80 } });
await expect(panel).toMatchAriaSnapshot(); // tooltip-open state
expect(await scanForA11yViolations()).toHaveNoA11yViolations(); // a11y holds mid-interaction

Keep these deterministic — see the canvas/uPlot anti-flake rules below (pin data, scope locators, wait for the renderer). Aria snapshots capture semantic structure, not pixels; leave pixel-level visual regression to Meticulous.

Canvas / uPlot anti-flake rules

These are the viz-specific additions to frontend-testing-strategy's generic anti-flake list. Avoid → Do:

Non-deterministic data / relative time ranges. Avoid random_walk + now-30m when asserting on shapes or coordinates. Do pin an absolute time range and a fixed seed / startValue so the render is identical every run. (timeseries tooltip #128617)
Coordinate-based hover/click on canvas. Avoid hardcoded x/y on .uplot. Do make data deterministic first; derive coords from rendered geometry, not constants. (xychart tooltip remains skipped #128389 for this reason)
Broad locators. Avoid page.locator('.uplot') — it also matches option-pane preview thumbnails. Do scope: getByGrafanaSelector(Panels.Panel.content).locator('.uplot').
Asserting before the renderer is ready. Do waitFor(() => expect(uPlotInstance?.status).toBe(1)) before any canvas snapshot/output assertion. (Sparkline/Heatmap/XYChart #127557)

Rules checklist

Read frontend-testing-strategy first — its checklist (Principles 1-4, test naming, mocking convention, generic anti-flake, SDLC gating) applies here too.
Step 1 — one data builder per file; getPanelProps + applyFieldOverrides for panel renders.
Step 2 — canvas panels → draw-call harness, deterministic, wait for status === 1.
Step 3 — E2E selectors-first; every panel gets an @a11y test plus interaction aria-snapshots.
Canvas/uPlot anti-flake — apply all 4 rules above, on top of the generic 7.

Verify

yarn test <path> (add --watchAll=false) — the new tests pass and actually fail when the asserted value is broken (mutate the expected value once to confirm it's not a no-op).
For E2E: yarn e2e:playwright <spec> (it starts its own server).
yarn typecheck if selectors or casts were added.

# Panel testing strategy

This skill builds on **`frontend-testing-strategy`** — read that first for the general
principles every Grafana frontend test is held to (the inverted testing diamond, asserting real
behavior instead of existence, avoiding AI slop, verifying a test reaches its target branch,
generic anti-flake rules, and the SDLC-phase gating). This skill covers what's specific to
visualization code on top of that: data-frame/panel-prop builders, the canvas draw-call snapshot
harness, panel accessibility and interaction-snapshot E2E, and canvas/uPlot-specific anti-flake
rules. The visualization codeowner paths are opted into the gating
`check-frontend-test-coverage.yml` check, so coverage that drops fails CI.

## Step 1 — Set up data with the repo's builders

Build data frames with the `@grafana/data` builders — **pick one and don't mix**
`toDataFrame` and `createDataFrame` in the same file:

```ts
import { createDataFrame, toDataFrame, arrayToDataFrame, FieldType, LoadingState } from '@grafana/data';
```

Use a **single canonical builder per file** with a `Partial<>` overrides object, rather than
bespoke frames per test:

```ts
function makeFrame(overrides: Partial<Options> = {}) {
  /* … */
}
```

To render a panel component, use the shared panel-props builder instead of hand-rolling props:

```ts
import { getPanelProps } from '../test-utils'; // public/app/plugins/panel/test-utils.ts
render(<BarChartPanel {...getPanelProps(defaultOptions, { fieldConfig })} />);
```

> **Gotcha — field config.** A panel unit test must call `applyFieldOverrides` itself with a

> **Gotcha — type inference.** If you're testing `guessFieldTypes` (or any inference), feed
> **untyped** raw fields (`as unknown as DataFrameDTO`). `createDataFrame` pre-sets `type`, so
> the function under test becomes a no-op and the test gives false confidence.

## Step 2 — HTML5 canvas / rendering panels: use the draw-call snapshot harness

Panels that draw to canvas (timeseries, heatmap, xychart, timeline, piechart, sparkline)
are tested by **capturing the ctx draw-call stream**, not by pixel-diffing. Follow the established harness:

```ts
// In the harness (public/app/plugins/panel/timeseries/TimeSeriesPanel.canvasTestUtils.tsx):
import {
  applyDefaultUPlotAxisMeasureTextMock,
  installCanvasPath2DShim,
  removeCanvasTransforms,
} from '@grafana/test-utils/canvas';

// In each *.canvas.test.tsx, mock grafana-ui's text measurement so layout is deterministic:
jest.mock('@grafana/ui/src/utils/measureText', () =>
  require('@grafana/test-utils/canvas').createGrafanaUiMeasureTextJestMock(() =>
    require('./TimeSeriesPanel.canvasTestUtils').getUPlotInstance()
  )
);
```

- Split suites by concern: `*.lines.canvas.test.tsx`, `*.fills.…`, `*.annotations.…`,
  `*.axisPlacement.…`, `*.axisRange.…` — each a focused `it.each` of cases.
- Assert with the custom matcher: `expect(events).toMatchCanvasSnapshot(context, { width, height })`.
- **Keep it deterministic** (this is where flake comes from): fixed `width`/`height`, UTC
  timestamps (`Date.UTC(...)`, `timeZone: 'utc'`), and wait for the renderer to be ready
  before asserting — `await waitFor(() => expect(uPlotInstance?.status).toBe(1))` (a `waitFor`
  callback must **throw** to retry, so it needs `expect`, not a bare boolean).

## Step 3 — E2E for interaction, accessibility, and interaction snapshots

The DataViz strategy is **unit-first**. Reserve Playwright for cross-component interaction
and per-panel smoke coverage. When you do write E2E:

- Add the selector to the **versioned `@grafana/e2e-selectors` package first**, wire
  `data-testid` into the JSX, then query it (use the `add-e2e-selectors` skill).
- Query by selector, never brittle CSS — in E2E `dashboardPage.getByGrafanaSelector(...)`,
  in unit `screen.getByTestId(selectors.components...)`.

```ts
import { test, expect } from '@grafana/plugin-e2e';

test.describe('Panels test: BarChart render', { tag: ['@panels', '@barchart'] }, () => {
  test('renders without error', async ({ gotoDashboardPage, selectors }) => {
    const page = await gotoDashboardPage({ uid: DASHBOARD_UID }); // provisioned devenv dashboard
    await expect(page.getByGrafanaSelector(selectors.components.Panels.Panel.headerCornerInfo('error'))).toBeHidden();
  });
});
```

### Accessibility — every panel gets an a11y check

**Every panel must have an E2E accessibility test.** Use the `scanForA11yViolations`
fixture and the `toHaveNoA11yViolations()` matcher, in a `describe`/test tagged `@a11y`.
Load the panel, wait for it to actually render (assert the panel title and the chart
element are visible — an empty panel trivially passes), then scan:

```ts
test.describe('a11y', { tag: ['@a11y'] }, () => {
  test('run a11y report', async ({ gotoDashboardPage, scanForA11yViolations, selectors, page }) => {
    const dashboardPage = await gotoDashboardPage({
      uid: DASHBOARD_UID,
      queryParams: new URLSearchParams({ viewPanel: 'panel-4' }),
    });
    await expect(dashboardPage.getByGrafanaSelector(selectors.components.Panels.Panel.title('…'))).toBeVisible();
    await expect(page.locator('.uplot')).toBeVisible(); // panel has drawn

    const report = await scanForA11yViolations({
      options: { runOnly: ['wcag2a', 'wcag2aa', 'wcag21a', 'wcag21aa', 'best-practice'] },
    });
    expect(report).toHaveNoA11yViolations();
  });
});
```

- Only pass `ignoredRules` for a documented, tracked pre-existing violation — add a `@todo`
  with the tracking issue rather than silently ignoring (e.g. `page-has-heading-one`,
  `region`, `color-contrast` are common app-shell noise, not panel bugs).
- Exemplars: `e2e-playwright/panels-suite/{histogram,xychart,table-nested,table-kitchenSink}.spec.ts`,
  and keyboard-a11y in `e2e-playwright/various-suite/panel-presets.spec.ts`.

### Interaction snapshots — cover a variety of states, not just first render

A panel's accessibility and structure change as the user interacts. For each panel, drive a
**variety of interaction states** and snapshot the resulting accessibility tree with
`toMatchAriaSnapshot`, re-running the a11y scan in the states that matter. Typical states
per panel type: default render, **hover / tooltip open**, **legend item toggled**, **sort /
filter applied** (table), **series selected**, **panel edit mode**, and **empty / no-data**.

```ts
const panel = dashboardPage.getByGrafanaSelector(selectors.components.Panels.Panel.content);
await expect(panel).toMatchAriaSnapshot(); // baseline structure
await panel.locator('.uplot').hover({ position: { x: 120, y: 80 } });
await expect(panel).toMatchAriaSnapshot(); // tooltip-open state
expect(await scanForA11yViolations()).toHaveNoA11yViolations(); // a11y holds mid-interaction
```

Keep these deterministic — see the canvas/uPlot anti-flake rules below (pin data, scope locators,
wait for the renderer). Aria snapshots capture semantic structure, not pixels; leave pixel-level
visual regression to Meticulous.

## Canvas / uPlot anti-flake rules

These are the viz-specific additions to `frontend-testing-strategy`'s generic anti-flake list.
**Avoid → Do:**

   remains skipped #128389 for this reason)_

개요

Panel testing strategy

Step 1 — Set up data with the repo's builders

Step 2 — HTML5 canvas / rendering panels: use the draw-call snapshot harness

Step 3 — E2E for interaction, accessibility, and interaction snapshots

Accessibility — every panel gets an a11y check

Interaction snapshots — cover a variety of states, not just first render

Canvas / uPlot anti-flake rules

Rules checklist
