Enums

  Enum representing the QEMU exit codes used to signal the result of test execution. Success signals that tests passed, while Failed indicates that at least one test failed.

Traits

• Testable
  Trait for marking types that can be tested in the kernel test suite.

Functions

• exit_qemu
  Exits the QEMU virtual machine with a specific exit code. This is typically used after tests to indicate success or failure.
• hlt_loop
  A simple infinite loop that halts the CPU. This is typically used when the kernel encounters an error or after the test suite completes.
• init
  Initializes various kernel components, including:
• test_panic_handler
  Handles kernel panics during tests by printing the error message to the serial console and exiting the QEMU emulator with a failure code.
• test_runner
  The test runner that executes a list of tests and exits with a result code. It uses serial_print! and serial_println! to print test results to the serial console. After all tests, the QEMU exit code is sent to indicate success or failure.
