Unit testing react-helmet meta tags

I am using react-helmet to add meta tags to create twitter card. Can you help me with writing test case for it.

        <title>{addon.name}</title>
        <meta name="twitter:card" content="summary" />
        <meta name="twitter:title" content={addon.name || ''} />
        <meta name="twitter:description" content={addon.summary || ''} />
        <meta name="twitter:image" content={addon.icon_url || ''} />
