## Test with static HTML
Dynamic testing of se-scraper takes too much time.
Save some html and initialize se-scraper by loading the search from disk.
### Disadvantage
static html gets outdated after some time
### Advantages
1. Let's us test corner cases that are missed easily
2. Testing is not reliable, since search engines do not always return the same results for the same query
3. As said, much faster
