## 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static html gets outdated after some time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
