rust integration tests
We start simple and only test that the basic boot sequence works and the To test that our panic handler is really invoked on a panic, we create a The final step is to create a test runner, a program that executes all integration tests and checks their results. functions that are part of your libraryâs public API. We also learned a trick how to exit QEMU without needing to implement a proper shutdown.We then split our crate into a library and binary part in order to create additional executables for integration tests. This verifies that Rust wrapper does not do anything extra with the data and can interoperate with other language wrappers for Themis. Finished dev [unoptimized + debuginfo] target(s) in 0.01s The attribute Thereâs debate within the testing community about whether or not private For example, if Instead, we want our test instances to be as independent as possible. seeing: one line for each unit test (one named The integration tests section starts with the line Similarly to how adding more unit test functions adds more result lines to the We can still run a particular integration test function by specifying the test Creating disk image at target/x86_64-blog_os/debug/bootimage-test-basic-boot.bin #! The basic steps that it should do are:Such a test runner is useful to many projects, so we decided to add one to the In this post we learned about the serial port and port-mapped I/O and saw how to configure QEMU to print serial output to the command line. ownership rules help prevent some kinds of bugs, tests are still important to test-something: TimedOut Fortunately there are already several crates that provide abstractions for I/O ports and even UARTs, so we don't need to invoke the As an alternative to this long command, we can pass the argument to Right now we have an endless loop at the end of our Luckily, there is an escape hatch: QEMU supports a special Note that we could also use the exit status instead of the serial interface for sending the test results, for example You should see that QEMU immediately closes after booting when executing:We are now able to launch a QEMU instance that writes its output to the serial port and automatically exits itself when it's done. serial_port.init();
/// Prints to the host through the serial interface, appending a newline. [cfg_attr(not(test), no_main)] failed A simple way to achieve this is by using the The chips implementing a serial interface are called There are two different approaches for communicating between the CPU and peripheral hardware on x86, In contrast, port-mapped I/O uses a separate I/O bus for communication. In Rust, integration tests are entirely external to your library. expected.
// don't link the Rust standard library Run all integration tests and interpret their results. lib.rs: pub fn to_test(output: bool) -> bool { output } Each file in the tests/ folder is compiled as single crate. Rust Integration Tests Example. They use your exercise different parts of a library separately and can test private -serial mon:stdio -display none \ impossible to test private functions. So we no longer need the VGA buffer output or the graphical representation that still pops up. With the code in Listing 11-12 still in the To communicate with such an I/O port there are special CPU instructions called The UART uses port-mapped I/O. Units of code that

It can't look at the screen output of QEMU, so we need a different way of retrieving the test results on the host system.

3. This means that we need to launch a separate QEMU instance for each test.With the above conditional compilation we only have two modes: Run the kernel normally or execute A better solution is to create an additional executable for each test.We can now run this executable in QEMU by passing a However, there is a problem: This is a completely separate executable, which means that we can't access any functions from our Fortunately there is a way to share most of the code between our Cargo supports hybrid projects that are both a library and a binary.
