- # Selects content from the RJS response.
- #
- # === Narrowing down
- #
- # With no arguments, asserts that one or more elements are updated or
- # inserted by RJS statements.
- #
- # Use the +id+ argument to narrow down the assertion to only statements
- # that update or insert an element with that identifier.
- #
- # Use the first argument to narrow down assertions to only statements
- # of that type. Possible values are <tt>:replace</tt>, <tt>:replace_html</tt>,
- # <tt>:show</tt>, <tt>:hide</tt>, <tt>:toggle</tt>, <tt>:remove</tta>,
- # <tt>:insert_html</tt> and <tt>:redirect</tt>.
- #
- # Use the argument <tt>:insert</tt> followed by an insertion position to narrow
- # down the assertion to only statements that insert elements in that
- # position. Possible values are <tt>:top</tt>, <tt>:bottom</tt>, <tt>:before</tt>
- # and <tt>:after</tt>.
- #
- # Use the argument <tt>:redirect</tt> followed by a path to check that an statement
- # which redirects to the specified path is generated.
- #
- # Using the <tt>:remove</tt> statement, you will be able to pass a block, but it will
- # be ignored as there is no HTML passed for this statement.
- #
- # === Using blocks
- #
- # Without a block, +assert_select_rjs+ merely asserts that the response
- # contains one or more RJS statements that replace or update content.
- #
- # With a block, +assert_select_rjs+ also selects all elements used in
- # these statements and passes them to the block. Nested assertions are
- # supported.
- #
- # Calling +assert_select_rjs+ with no arguments and using nested asserts
- # asserts that the HTML content is returned by one or more RJS statements.
- # Using +assert_select+ directly makes the same assertion on the content,
- # but without distinguishing whether the content is returned in an HTML
- # or JavaScript.
- #
- # ==== Examples
- #
- # # Replacing the element foo.
- # # page.replace 'foo', ...
- # assert_select_rjs :replace, "foo"
- #
- # # Replacing with the chained RJS proxy.
- # # page[:foo].replace ...
- # assert_select_rjs :chained_replace, 'foo'
- #
- # # Inserting into the element bar, top position.
- # assert_select_rjs :insert, :top, "bar"
- #
- # # Remove the element bar
- # assert_select_rjs :remove, "bar"
- #
- # # Changing the element foo, with an image.
- # assert_select_rjs "foo" do
- # assert_select "img[src=/images/logo.gif""
- # end
- #
- # # RJS inserts or updates a list with four items.
- # assert_select_rjs do
- # assert_select "ol>li", 4
- # end
- #
- # # The same, but shorter.
- # assert_select "ol>li", 4
