Capybara content matchers cheat sheet

There's a cheat sheet I use to determine the capybara content matcher to use for a specific purpose:

##### Wait for some text to eventually be there:
```
expect(page).to have_content('some text')
```
Succeeds as soon as the text is there and can be very fast.

##### Wait for some text to be - and stay - there:
```
expect(page).not_to have_no_content('some text')
```
Succeeds if the text stays there for the whole `default_max_wait_time` and is therefore **always** slow. But sometimes needed.

##### Wait for some text to eventually disappear:
```
expect(page).to have_no_content('some text')
```
Succeeds as soon as this text is not there and can be very fast.

##### Wait for some text to be - and stay - absent:
```
expect(page).not_to have_content('some text')
```
Succeeds if the text stays absent for the whole `default_max_wait_time` and is therefore **always** slow. But sometimes needed.
