Kernel-based testing for Drupal modules using KernelTestBase to validate services, DB operations, and hooks with minimal bootstrap.
Run kernel tests for your module by placing tests under docroot/modules/custom/your_module/tests/src/Kernel and running the PHPUnit command that targets those tests.

Drupal kernel tests using KernelTestBase validate service interactions and database operations with minimal bootstrap. You place tests under tests/src/Kernel and use explicit module loading along with assertions to verify entity schemas, config installations, and hook behavior.
You need a kernel test when you require isolated, fast verification of entity schemas, config installations, and kernel-level logic without the overhead of a full browser. KernelTestBase provides minimal bootstrap configuration to test service containers and database operations efficiently.
You install entity schemas and config in a Drupal KernelTestBase setup by applying specific setup patterns including installEntitySchema, installSchema, and installConfig. These methods prepare the minimal bootstrap environment required for testing module behavior.
Yes, you can test Drupal hooks and entity operations without a full browser by using KernelTestBase. It provides an isolated environment with minimal bootstrap configuration to explicitly verify outcomes for entity operations, config, and hooks through direct assertions.
KernelTestBase is limited to testing kernel-level logic, service interactions, and database operations with minimal bootstrap. It does not handle browser-based interactions or full UI testing, requiring explicit module loading and explicit assertions to verify all outcomes.
You place PHPUnit kernel test files for a custom Drupal module under docroot/modules/custom/your_module/tests/src/Kernel. You then run the PHPUnit command targeting those tests to execute the kernel-level validation for your module.
