Ask HN: Are there any LLM projects for creating integration tests?

3 pointsgitgud3 comments

I’m curious if anyone has seen a project involving LLM’s that takes a series of user actions and creates integration test code for them, something like:

    I goto to example.com
    I click the search bar
    I type in “fruit”
    Expect to see a list of fruit

Then the LLM would execute something like playwright to achieve each of these steps and report back if any steps failed…

Are you looking for a web service that does the whole thing? Otherwise asking ChatGPT gives you

convert this free text

  I goto to example.com
  I click the search bar
  I type in “fruit”
  Expect to see a list of fruit

to playwright script

const { chromium } = require('playwright');

(async () => { const browser = await chromium.launch(); const context = await browser.newContext(); const page = await context.newPage();

  // Navigate to example.com
  await page.goto('https://example.com');

  // Click the search bar
  await page.click('input[type="search"]');

  // Type in "fruit"
  await page.type('input[type="search"]', 'fruit');

  // Press Enter to submit the search
  await page.press('input[type="search"]', 'Enter');

  // Wait for the page to load
  await page.waitForLoadState('networkidle');

  // Expect to see a list of fruit
  const fruitList = await page.$$('ul li');
  if (fruitList.length > 0) {
    console.log('List of fruit found!');
  } else {
    console.error('Failed to find the list of fruit.');
  }

  // Close the browser
  await browser.close();

})();

I have created a project for easily writing this type of test with YAML:

I dont think that this type of task is really appropriate for an LLM though. It is better to use hard, prewritten abstractions for the truly deterministic stuff (e.g. click).

For other situations where you may need to do subtle trade offs (e.g. choosing an HTML selector for the search bar) an LLM will generally do a bad job.

I have never heard about the LLM-based solution, but the tests written with help of Cucumber (https://cucumber.io/tools/cucumber-open/) framework looks very similar to what you're asking about.
