# Security Tests
|
|
|
|
Test each security boundary where user input affects authorization, rendered output, or query construction. A defect at such a boundary can be difficult to detect because the feature may continue to work.
|
|
|
|
Write a test for each of these cases:
|
|
|
|
- **Cross-tenant access.** Request a record of a different tenant, team, or organization. Read `rules/endpoint-tests.md` for why the response should be `404` rather than `403`.
|
|
- **Each unprivileged role.** Use a data provider over the roles that the endpoint must refuse.
|
|
- **Escaping user-provided content.** Test escaping in HTML and mail. Include names and every free-text field a template renders. Assert that dangerous characters are escaped and the raw value is absent. Do not assert an exact entity for a quote, because Markdown and mail CSS inliners may decode it.
|
|
- **Injection into dynamic query components.** Examples include sort columns, filter fields, and sort directions.
|
|
- **An unexpected key** in a payload or configuration array. A merge that accepts every key can set an attribute the user must not control.
|
|
|
|
```php
|
|
public function test_escapes_dangerous_content_in_the_notification(): void
|
|
{
|
|
$organization = Organization::factory()->make([
|
|
'name' => "O'Reilly <script>alert('xss')</script>",
|
|
]);
|
|
|
|
$content = (new QuotaApproaching($organization, 80))->toMail()->render();
|
|
|
|
$this->assertStringContainsString('<script>', $content);
|
|
$this->assertStringNotContainsString("<script>alert('xss')</script>", $content);
|
|
}
|
|
```
|
|
|
|
Laravel provides defenses against mass assignment, unauthorized access, and unescaped output. Test that the application applies the appropriate defense to each attribute, route, and template.
