Assert result

JavaScript Perl PHP Python Ruby

Expected result

OK

Explanation

We have more chances of testing API through network, so this code is getting the result through network and checking the output.

Programming Codes

JavaScript

const request = require('request');
const cheerio = require('cheerio');
 
const target_url = "https://www.yahoo.com/";
request(
    { method: 'GET', uri: target_url, gzip: true}, 
    function(err, res, content) {  
        const $ = cheerio.load(content);
        console.assert($('title').text().toLowerCase().match("yahoo"), "yahoo is not included in title");
        console.log("OK");
    }
);

PHP

<?php
$target_url = "https://www.yahoo.com/";
$context = stream_context_create(array('http' => array(
    'method' => "GET",
    'header' => implode("\r\n", array('Accept-Encoding: gzip,deflate'))
)));
$content = file_get_contents($target_url, false, $context);
if (isGzipResponse($http_response_header)) {
    $content = gzdecode($content);
}
$matches = [];
if( preg_match('!<title>(.*?)</title>!is', $content, $matches) ) {
  assert(preg_match('!yahoo!is', $matches[1]) ,"yahoo is not included in title");
  print("OK\n");
}
else{
  die("Failed to get content");
}
 
function isGzipResponse($headers) {
    foreach($headers as $header) {
        if (stristr($header, 'content-encoding') and stristr($header, 'gzip')) {
            return true;
        }
    }
}

Perl

use Carp::Assert;
use HTML::TagParser;
use LWP::UserAgent;

my $ua = new LWP::UserAgent;
my $target_url = "https://www.yahoo.com/";
my $resp = $ua->get($target_url);
if($resp->is_success) {
  my $html = HTML::TagParser->new($resp->content);
  my $title = $html->getElementsByTagName( "title" );
  if(ref $title){
    assert($title->innerText()=~ m!yahoo!i, "yahoo is not included in title");
    print("OK\n");
  }
  else{
    die("title tag is missing");
  }
}
else{
  die("Failed to crawl ".$target_url."\n".$resp->status_line);
}

Python

from pyquery import PyQuery
import re

target_url = "https://www.yahoo.com/"
pq = PyQuery(url=target_url)
assert re.search(r"Yahoo", pq('title').text(), re.IGNORECASE), "yahoo is not included in title"
print("OK")

Ruby

require 'open-uri'
require 'nokogiri'

target_url = "https://www.yahoo.com/"
doc = Nokogiri.HTML(open(target_url))
doc.search('title').each do |elm|
  raise "yahoo is not included in title" unless elm.content.match(/yahoo/i)
  puts("OK")
  break
end
