Assert Response/View is Translated

[olivermbs]

Much like the "assertSee" assertion, would perhaps an "assertViewTranslationsExist" assertion be useful?

The assertion could:

• Check translations used with @lang(), __(), and trans()
• Verify each translation key exists and has content
• Support passing view data and specific locales
• Provide clear error messages listing missing translations

Example usage:

public function test_about_page_translations()
{
    $this->assertViewTranslationsExist('about');
    
    // With view data
    $this->assertViewTranslationsExist('welcome', ['name' => 'Test']);
    
    // Test specific locale
    $this->assertViewTranslationsExist('about', [], 'es');
}

Thoughts?

I wouldn't say, translations belong specifically to views, so maybe $this->assertTranslationsExist() would be better. I mean, it could be, that you have a very simple case like this, which isn't a view:

return response(__('some.key'));

Also, $locale could probably be string|string[]
