Compare with:

assert_turbo_stream(action:, target: nil, targets: nil, count: 1, &block)

Assert that the rendered fragment of HTML contains a ‘<turbo-stream>` element.

Options

:action [String] matches the element’s [action] attribute
:target [String, #to_key] matches the element’s [target] attribute. If the value responds to #to_key, the value will be transformed by calling dom_id
:targets [String] matches the element’s [targets] attribute
:count [Integer] indicates how many turbo streams are expected. Defaults to 1.

Given the following HTML fragment:
```
<turbo-stream action="remove" target="message_1"></turbo-stream>
```
The following assertion would pass:
```
assert_turbo_stream action: "remove", target: "message_1"
```

You can also pass a block make assertions about the contents of the element. Given the following HTML fragment:

  <turbo-stream action="replace" target="message_1">
    <template>
      <p>Hello!</p>
    <template>
  </turbo-stream>

The following assertion would pass:

  assert_turbo_stream action: "replace", target: "message_1" do
    assert_select "template p", text: "Hello!"
  end

Parameters

target key = nil
targets key = nil
