Visualizaçõesreact-testing-library: some portion of debug's output is not visible
I am using react jest with react testing library to test my component. I am facing a weird issue. I am usng debug return by render from testing-library.
test('component should work', async () => {
const { findByText, debug } = render(<MyComponent />);
const myElement = await findByText(/someText/i);
debug();
});
As you can see in the screenshot there are incomplete dev and closing tags for parents are missing.

You need to change the value of DEBUG_PRINT_LIMIT env variable (default is 7000).
For example, run your tests with: DEBUG_PRINT_LIMIT=10000 yarn test

I am using this version: "@testing-library/react": "^11.0.4"
able to do just like below, we can change 300000 as the max length of output.
debug(undefined, 300000)

The second argument of the debug() function can be used to set maxLengthToPrint.
E.g. to print everything in myElement using the recommended screen approach:
import {render, screen} from '@testing-library/react'
render(<MyComponent />);
const myElement = await screen.findByText(/someText/i);
const maxLengthToPrint = 100000
screen.debug(myElement, maxLengthToPrint);
