## TL;DR

`getByText` matches per-element text, so "Hello world" split across two spans matches neither span. Use a function matcher that checks the combined textContent, or match a stable substring with exact set to false.

## Error

```text
Unable to find an element with the text: Hello world. This could be because the text
is broken up by multiple elements. In this case, you can provide a function for your
text matcher to make your matcher more flexible.
```

## Steps

1. Confirm the split with `screen.debug()`: the string should appear across separate child elements. Expected: you see the markup dividing the text.
2. Replace the string matcher with a function matcher. Expected: the query returns the parent element holding the full text.
```js
screen.getByText(function (content, element) {
  return element.textContent === 'Hello world'
})
```
3. Alternatively match a stable substring: `screen.getByText('Hello', { exact: false })`. Expected: it matches as long as that substring is unique on the page.
4. Rerun the test. Expected: it passes with no matcher error.

## When to use

- The error message itself suggests the text is broken up by multiple elements.
- The text includes inline formatting (strong, em, line breaks) that splits it.
- i18n interpolation or variables split a sentence across elements.

## When not to use

- The text never renders; check conditional rendering first.
- The text arrives after async work; use findByText, which waits.
- You need the exact child element, not the parent; restructure the component markup instead.

## Tool compatibility

- @testing-library/dom 8 and newer, @testing-library/react 13 and newer.
- jest, Vitest, and Cypress component testing.

## Variant phrasings

### This could be because the text is broken up by multiple elements

The diagnostic sentence inside the error. It is telling you the fix: provide a function matcher.

### you can provide a function for your text matcher to make your matcher more flexible

The suggested remedy in the same error. The function receives each element and you compare textContent.

## Why it happens

The default text matcher compares each element's own text nodes and ignores children, so a parent whose full text spans several children never matches a plain string.

## Edge cases

- A function matcher can match several elements, which throws a "multiple elements" error; scope it by checking the element tag or using a container.
- Whitespace and line breaks inside textContent need normalizing; collapse spaces before comparing.
- Matching the parent means assertions on its children still work, but be deliberate about which node you assert on.
