Class

TwigDeprecationsTest
Tests deprecating variables passed to twig templates.

Namespace

Drupal\KernelTests\Core\Theme

Code

public function testParentVariableDeprecation() : void {
    // 'foo' is used before the child template is processed, so this test
    // shows that processing the child does not lead to parent usage being
    // forgotten.
    // 'gaz' is used in the child template but only deprecated in the parent
    // template, so no deprecation error is triggered for it.
