For the love of all things decent, please read the usage guide provided by the script. Don't try any funny buisness, just run python3 tests from the base directory of the the scraper. Make sure that the tests are in a subdirectory of the project directory and that it is gitignored from your project repository.
The script caches results from the Stack Overflow API to avoid hitting the rate limit. But your webscraper is not cached, so be wary of the rate limits.
If you would like to contribute test cases, please add them to the test_cases.json file in the format:
{
// Endpoint (preceded by a forward slash) ? Query string
"/collectives?key=value&another_key=another_value"
}
