[Question] Loop tests based on API data array

I’m trying to get the details of the test from db via API, but when I try to fetch the data from API endpoint and run the test it fails with no tests found. Please find the code I’m using below.

import fetch from "node-fetch";
import { test } from "../steps/base-test";

test.describe.serial("Test Suite", () => {    
    getSuiteTests("http://localhost:8090/v7.4/tests/101").then(data => {
        for (const suiteTest of JSON.parse(JSON.stringify(data))) {
            console.log("Test: ", suiteTest);
            test(`${suiteTest.TestSequence}_${suiteTest.TestName}`, async ({ page }) => {
                console.log("Inside Test Case", suiteTest.TestDescription);
            });
        }
    });
});

async function getSuiteTests(url: string): Promise<string> {
    const response = await fetch(url);
    let data = await response.json();
    return data;
}

Note: If I wrap getSuitesTest inside test(i.e. opposite to above code), it actually displays the data from the API.

[
	{
		"TestID": 1003,
		"TestSequence": "TC01",
		"TestName": "SubscribeToNewsLetterTest",
		"TestDescription": "To verify that user is able to Subscribe to NewsLetter",
		"RunTest": true
	},
	{
		"TestID": 1004,
		"TestSequence": "TC02",
		"TestName": "UnsubscribeToNewsLetterTest",
		"TestDescription": "To verify that user is able to Unsubscribe from NewsLetter",
		"RunTest": true
	}
]

Please suggest what I’m doing wrong here.

The way I have seen this done is to have a separate program, that runs before the tests, read the data and write a JSON file. When the tests run they import the JSON file, loop through the data, and call test as needed to register all of the tests.

The approach described by @daddyman is a great one. Alternatively, you can have a single test with many steps, depending on what you find more convenient.

I think it is unlikely that Playwright Test is going to change in this regard, so closing the issue. Thank you for the discussion!
