import { AppComponent } from './app.component';

describe('AppComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
    }).compileComponents();
  }));

  it('should create the app', () => {
    const fixture = TestBed.createComponent(AppComponent);
    const app = fixture.debugElement.componentInstance;
    expect(app).toBeTruthy();
  });

  it(`should have as title 'my-app'`, () => {
    const fixture = TestBed.createComponent(AppComponent);
    const app = fixture.debugElement.componentInstance;
    expect(app.title).toEqual('my-app');
  });

  it('should render title in a h1 tag', () => {
    const fixture = TestBed.createComponent(AppComponent);
    fixture.detectChanges();
    const compiled = fixture.debugElement.nativeElement;
    expect(compiled.querySelector('h1').textContent).toContain('Welcome to my-app!');
  });
});

Running Unit Tests:
- Execute Tests: Run ng test to execute the unit tests using Karma.

Step-by-Step Guide for End-to-End Tests:

Setup Protractor:

Protractor Configuration: Ensure Protractor is installed and configured.

// protractor.conf.js
exports.config = {
  allScriptsTimeout: 11000,

  ],
  capabilities: {
    'browserName': 'chrome'
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
  }
};

Writing End-to-End Tests:

Example Test:

import { AppPage } from './app.po';
import { browser, logging } from 'protractor';

describe('workspace-project App', () => {
  let page: AppPage;

  beforeEach(() => {
    page = new AppPage();
  });

  it('should display welcome message', () => {
    page.navigateTo();
    expect(page.getTitleText()).toEqual('Welcome to my-app!');
  });

  afterEach(async () => {
    const logs = await browser.manage().logs().get(logging.Type.BROWSER);
    expect(logs).not.toContain(jasmine.objectContaining({
      level: logging.Level.SEVERE,
    } as logging.Entry));
  });

Sure, here are the provided examples translated into Ruby:

AWS Transcribe Example in Ruby

require 'aws-sdk-transcribe'  # v2: require 'aws-sdk'

client = Aws::TranscribeService::Client.new(region: 'us-east-1')

job_name = 'transcription-job'
job_uri = 's3://your-bucket/your-media-file.mp4'

response = client.start_transcription_job({
  transcription_job_name: job_name,
  media: { media_file_uri: job_uri },
  media_format: 'mp4',
  language_code: 'en-US',
})

puts "Transcription job started with job name: #{response.transcription_job.transcription_job_name}"

Generating Text with GPT-3 Example in Ruby

Since OpenAI does not have an official Ruby client, you would typically use an HTTP client like net/http or httparty to make requests to the OpenAI API. Here’s how you could do it with httparty:

require 'httparty'

api_key = 'YOUR_API_KEY'
url = "https://api.openai.com/v1/engines/davinci/completions"

headers = {
  "Content-Type" => "application/json",
  "Authorization" => "Bearer #{api_key}"
}

body = {
  prompt: "Summarize the following text: ...",
  max_tokens: 150
}.to_json

response = HTTParty.post(url, headers: headers, body: body)
puts response.parsed_response['choices'][0]['text'].strip

Summary Generation Using GPT-3 in Ruby

require 'httparty'

api_key = 'YOUR_API_KEY'
url = "https://api.openai.com/v1/engines/davinci/completions"

headers = {
  "Content-Type" => "application/json",
  "Authorization" => "Bearer #{api_key}"
}

summary_prompt = "Summarize the following transcript: #{transcription_text}"

body = {
  prompt: summary_prompt,
  max_tokens: 100
}.to_json

response = HTTParty.post(url, headers: headers, body: body)
summary = response.parsed_response['choices'][0]['text'].strip
puts summary

These examples demonstrate how to use AWS Transcribe and OpenAI GPT-3 APIs in Ruby. For running the AWS Transcribe code, ensure you have the AWS SDK for Ruby installed (gem install aws-sdk). For the OpenAI example, you need the httparty gem (gem install httparty). Adjust the api_key and other parameters as needed for your use case.
