Here is a spitball sample of how you can test your getLinksPage and loop functions as independent units using ScalaTest. Disclaimer: syntax may not be 100%; adapt as needed. case class Crawler () { def getConnection (url: String) = Jsoup.connect (url) def getLinksPage (urlToCrawl: String): Option [List [String]] = { val conn = getConnection ...
Crawler Restrictions. You may often need to test a specific area of your web application, such as the home page, or prevent scanning certain areas such as the admin panel. The Crawler Restrictions tab allows you to set a URL allowlist or denylist for crawling. When a scan begins, AppSpider visits the seed URLs specified in the Main Settings.

The web has changed signiflcantly since the days of early crawlers [4], [23], [25], mostly in the area of dynamically generated pages and web spam.

For the rest, here is how it works. Firstly to run it do the following: ruby search-engine-main.rb -c web -d 3 -p 100 -f 'urls.txt'. where: -c (is either 'web' or 'domain') -d (is the depth of the crawl, it will only look at links this many levels below the initial urls) -p (is the page limit, will not crawl more than this many pages ...
Windows 2000 automatically sets a configuration option to use HTTP 1.1 for connecting to web sites. Many, many web sites do not use that version but continue to use HTTP 1.0, so the automatic setting may prevent connections. This is the reason why Xenu would not run for me. When I disabled that setting, Xenu performed properly.
A typical crawler works in the following steps: Parse the root web page ("mit.edu"), and get all links from this page. To access each URL and parse HTML page, I will use JSoup which is a convenient web page parser written in Java. Using the URLs that retrieved from step 1, and parse those URLs
The last idea I have is to implement a crawler algorithm similar to the ones used by Google's own web spiders. My above crawler algorithms only consider the main 'home' addresses, consisting of the 16 characters and the .onion, even though most sites have many pages (fh5kdigeivkfjgk4.onion would be indexed, fh5kdigeivkfjgk4.onion/home would not).

Mocking: This is the process of substituting the response from 3rd dependencies so that they are not actually called during the test. This is the approach used here. Instead of using the crawler.js module to call the url, I used Jest to Mock the module and return a response. This makes the test faster and more predictable.
