Question

Confirm button title by verifying part of the label that contains a space

I'm facing an issue with clicking a button using the following code:

await page.getByRole('button', { name: '3 Employees' }).click();

The problem is that the button's name fluctuates based on the number of employees, causing the hardcoded value to fail. Using a locator method with only the word 'Employees' could result in matching another button with the same locator and text. I also want to avoid using nth() method.

What I aim to achieve is modifying the code so it searches only for the 'Employees' part, including the space between 3 and 'Employees'. Is there any way to consider the 3 as a random value like "{randomvalue} Employees"?

When dealing with a specific button on a page, utilizing a regex can be effective as long as there are no other instances of /^\d+ Employees$/ elements present:

import {expect, test} from "@playwright/test"; // ^1.42.1

const html = `<!DOCTYPE html><html><body>
<button></button>
<script>
setTimeout(() => {
  document.querySelector("button").textContent =
    ~~(Math.random() * 100) + " Employees";
}, 3000);
</script>
</body></html>`;

test("{n} Employees button can be clicked", async ({page}) => {
  await page.setContent(html);
  await page.getByRole("button", {name: /^\d+ Employees$/}).click();
});

Make sure to take note of the ^ and $ anchors, which ensure an exact match excluding any leading/trailing whitespace. If you prefer to have a substring match, simply exclude these anchors.

If there are multiple elements that match this criteria, it might be beneficial to analyze the parent chain to pinpoint a specific button instead of relying on first/last/nth positions to avoid confusion.

Lastly, if there's a way to guarantee the rendering of a specific number of employees on the page, explore that option before resorting to the provided code. Only utilize the above code when all other approaches have been exhausted.
