What are the steps to add code into the Monaco Editor using Playwright?

As I explore the world of Playwright, I am faced with a challenge regarding testing a feature that involves a monaco editor. Unfortunately, my search in Playwright documentation and forums did not yield any relevant information.

Here is the test scenario I'm working on:

async ({ page }) => {
    const testPage= new TestPage(page);

    await testPage.navigateTo();
    //dosomething
    await page.waitForSelector(#monaco-editor-selector);
    //Paste a script in monaco editor
}

I would greatly appreciate any assistance on this matter!

Answer №1

Playwright is currently dealing with an issue #14126 that addresses this specific problem, as shown below.

test('To input text into Monaco Editor', async ({ page }) => {
  const monacoEditor = page.locator(".monaco-editor").nth(0);
  await monacoEditor.click();
  await page.keyboard.type('Hello world!');
})

If you have multiple Monaco Editors and need to target them individually, you can enclose them in a <div> with a test ID. Unfortunately, directly setting data-testid on the Monaco Editor component is not supported.

<div data-testid="my-test-id">
  <MonacoEditor ... />
</div>

test('To input text into Monaco Editor enclosed within a div', async ({ page }) => {
  const monacoEditor = page.getByTestId('my-test-id').locator(".monaco-editor").nth(0);
  await monacoEditor.click();
  await page.keyboard.type('Hello world!');
})
