Question:How do i get the "Scenario" details?

[prasadroks]

I want to fetch the steps that are written in feature file and print before the test starts.

when i tried to implement below code its giving error for me on scenario

// Print all steps of the scenario
const steps = scenario.getSteps();
steps.forEach(step => {
const stepText = step.getText();
const hasDataTable = step.getArgument() instanceof DataTable;
console.log(Step: ${stepText});
console.log(Contains Data Table: ${hasDataTable});
});

Feature files are not loaded inside test workers for performance reason.
Could you share the final goal, why do you want to print steps?

[prasadroks]

Based on steps, if step has data table then i want to set up the values in some variables before the start of the test.

So, no built-in methods to achieve that for now.
If it's a particular step, maybe you can set up these values inside that step? E.g.:

Given('my step with data table', async function (dataTable) {
  // set up values for step with data table
  // ...
});

Another more tricky option is to read test title and file from $testInfo fixture, then read feature file and get all steps of the scenario:

Before(async ({ $testInfo }) => {
  console.log('Starting test:', $testInfo.title, $testInfo.file);
  // 1. get location of feature file by $testInfo.file
  // 2. read and parse feature file
  // 3. find scenario by $testInfo.title
  // 4. iterate through steps and check for data table
});

how would you iterate through steps ? while iteration we may get the steps text ?
Before(async ({ $testInfo }) => {
console.log('Starting test:', $testInfo.title, $testInfo.file);

// 4. iterate through steps and check for data table
});

The approach is like here:

import path from 'node:path';
import fs from 'node:fs';
import * as Gherkin from '@cucumber/gherkin';
import * as Messages from '@cucumber/messages';

const uuidFn = Messages.IdGenerator.uuid();
const builder = new Gherkin.AstBuilder(uuidFn);
const matcher = new Gherkin.GherkinClassicTokenMatcher(); // or Gherkin.GherkinInMarkdownTokenMatcher()
const parser = new Gherkin.Parser(builder, matcher);

Before(async ({ $testInfo }) => {
  const featureFile = './features/' + path.basename($testInfo.file).replace('.spec.js', '');
  const featureContent = fs.readFileSync(featureFile, 'utf-8');
  const gherkinDocument = parser.parse(featureContent);
  const pickles = Gherkin.compile(gherkinDocument, featureFile, uuidFn);
  const pickle = pickles.find((p) => p.name === $testInfo.title);

  console.log(pickle?.steps);
});
