Website Vocabulary Analyzer Test

Hello! Welcome!

In this test you are required to write a golang program that counts the number of occurrences of certain words in a group of websites.

Input

  • 'vocabulary' - A vocabulary of predefined words. Those are the only words that we are interested in counting.

  • 'urls' - A list of URLs to html pages.

Goal

Fetch each of the pages from the web, count the number of occurrences of each word from the dictionary in them, and print out the results.

Gotchas

  • We are only interested in full-word match. No need to look for partial or fuzzy matches.

  • To make things easier, you do not have to distinguish between the html structure and body. You can treat the entire html as a text document.

  • Your code should be clean and well organized.

  • The list of urls is fairly long, which could cause the program to run for a long time. Eventually, we'd like for you to try and make it run as fast as possible.

  • Consider that there is no limit on the size of the fetched URLs

  • Consider that some websites may respond very slowly

Code Structure

  • main.go - the entry point for the program which you will be running. Main already initializes the input params (vocabulary and urls).

in here you will find a struct WordCounter with a method Count(urlList, dictionaryWords []string) (map[string]int, error) which you need to implement.

# running the code
➜  word-counter-task-go go run main.go
got dictionary of 466551 words
got 105 urls to count

... more output pending your work
  • word_counter_test.go - to make development easier we've written a sanity test.
# running the test
➜  word-counter-task-go go test .
--- FAIL: TestSanityWordCounter (2.83s)
    --- FAIL: TestSanityWordCounter/hello (0.00s)
        word_counter_test.go:37: hello count should be 3
    --- FAIL: TestSanityWordCounter/goodbye (0.00s)
        word_counter_test.go:37: goodbye count should be 1

# will PASS after you implement your code!
