<p>The <code>not</code> predicate negates its child predicate.</p>

<testScenario name='tcp not example'>
    <step type='http'>
<pre><code>POST /imposters HTTP/1.1
Host: localhost:<%= port %>
Accept: application/json
Content-Type: application/json

{
  "port": 4552,
  "protocol": "tcp",
  "mode": "text",
  "stubs": [<strong class='highlight1'>
    {
      "responses": [{ "is": { "data": "not test" } }],
      "predicates": [{ "not": { "equals": { "data": "test\n" } } }]
    }</strong>,<strong class='highlight2'>
    {
      "responses": [{ "is": { "data": "test" } }],
      "predicates": [{ "equals": { "data": "test\n" } }]
    }</strong>
  ]
}</code></pre>
    </step>

<p>The first stub matches if the <code>is</code> sub-predicate does not match:</p>

    <step type='exec'>
<pre><code>echo '<strong class='highlight1'>production</strong>' | nc localhost 4552</code></pre>

        <assertResponse>
<pre><code><strong class='highlight1'>not test</strong></code></pre>
        </assertResponse>
    </step>

<p>As expected, the second stub matches if the <code>is</code> sub-predicate does match:</p>

    <step type='exec'>
<pre><code>echo '<strong class='highlight1'>test</strong>' | nc localhost 4552</code></pre>

        <assertResponse>
<pre><code><strong class='highlight1'>test</strong></code></pre>
        </assertResponse>
    </step>

    <step type='http'>
<code class='hidden'>DELETE /imposters/4552 HTTP/1.1
