Failed-screenshot-maker NPM

failed-screenshot-maker

failed-screenshot-maker is a utility for Selenium WebDriver tests that automatically captures screenshots of failed tests and attaches them to an Allure report. It simplifies the process of visualizing test failures by saving screenshots to a local directory and embedding them directly into your Allure test reports.

Installation

You can install failed-screenshot-maker using npm:

npm install failed-screenshot-maker --save-dev

Usage

Import the failed-screenshot-maker function into your test suite, and use it in an afterEach or finally block to capture screenshots of failed tests.

Example with Mocha and Selenium WebDriver

import failedScreenshotMaker from 'failed-screenshot-maker';
import { Builder } from 'selenium-webdriver';
import { describe, it, afterEach, after } from 'mocha';

describe('My Test Suite', function() {
  let driver;

  before(async function() {
    driver = await new Builder().forBrowser('chrome').build();
  });

  afterEach(async function() {
    await failedScreenshotMaker(this.currentTest, driver);
  });

  after(async function() {
    await driver.quit();
  });

  it('should perform a test that may fail', async function() {
    await driver.get('http://example.com');
    // Add your test steps here
  });
});

Parameters

The failedScreenshotMaker function accepts two parameters:

test: An object representing the current test context, typically provided by the testing framework (e.g., Mocha).
- test.state: string - The state of the test ('failed', 'passed', etc.).
- test.title: string - The title or name of the test.
driver: The Selenium WebDriver instance used for browser automation.
- driver.takeScreenshot(): Function - A method that captures a screenshot and returns it as a base64-encoded string.
  - Returns: Promise<string> - A promise that resolves with the base64-encoded screenshot.
