<h1>Snapshots</h1>
<% if @grouped_by_test_class.empty? %>
<p>
In your integration tests, once a request has been made,
add <code>#take_screenshot</code>. Run the tests with <code>TAKE_SNAPSHOTS=1</code>, and the snapshot will appear here.
</p>
<p>Look below at an example integration test.</p>
<pre>
require "minitest/autorun"
require "rack/test"
require "application"
<mark>require "snapshot_ui/test/minitest_helpers"</mark>
class ApplicationTest < Minitest::Spec
include Rack::Test::Methods
<mark>include SnapshotUI::Test::MinitestHelpers</mark>
def app
@app ||= Application.new
end
it "renders the root page" do
get "/"
<mark>take_snapshot last_response</mark>
_(last_response.body).must_match("To see a world in a grain of sand...")
end
end
</pre>
<p>
To activate live updates for this page, execute the following command in your terminal.<br>
</p>
<pre>
bundle exec snapshot_ui watch SNAPSHOT_DIRECTORY</pre>
<p>
where <code>SNAPSHOT_DIRECTORY</code> is a path to a directory that contains
snapshot UI data, e.g. <code>tmp/snapshot_ui</code>.
