3 Crosvm runs on a variety of platforms with a significant amount of platform-specific code. Testing
6 ## Types of tests
8 ### Unit Tests
10 Unit tests are your standard rust tests embedded with the rest of the code in `src/` and wrapped in
13 Unit tests **cannot make any guarantees on the runtime environment**. Avoid doing the following in
14 unit tests:
16 - Avoid kernel features such as io_uring or userfaultfd, which may not be available on all kernels.
17 - Avoid functionality that requires privileges (e.g. CAP_NET_ADMIN)
18 - Avoid spawning threads or processes
19 - Avoid accessing kernel devices
20 - Avoid global state in unit tests
22 This allows us to execute unit tests for any platform using emulators such as qemu-user-static or
25 ### Documentation tests argument
28 [documentation tests](https://doc.rust-lang.org/rustdoc/write-documentation/documentation-tests.htm…
31 Documentation tests are slow and not run as part of the usual workflows, but can be run locally
38 ### Integration tests argument
41 [integration testing](https://doc.rust-lang.org/rust-by-example/testing/integration_testing.html).
42 Integration tests are written just like unit tests, but live in a separate directory at `tests/`.
44 Integration tests **guarantee that the test has privileged access to the test environment**. They
45 are only executed when a device-under-test (DUT) is specified when running tests:
48 ./tools/run_tests --dut=vm|host
51 ### End To End (E2E) tests argument
53 End to end tests live in the `e2e_tests` crate. The crate provides a framework to boot a guest with
56 E2E tests are executed just like integration tests.
58 ### Downstream Product tests argument
64 Upstream crosvm is not involved in these tests and they are not executed in crosvm CI.
68 Crosvm tests are executed in parallel, each test case in its own process via
71 This requires tests to be cautious about global state, especially integration tests which interact

80 The platforms below can all be tested using `tools/run_tests -p $platform`. The table indicates how
81 these tests are executed:
83 | Platform | Build | Unit Tests | Integration Tests | E2E Tests |
84 | :-------------------------- | :---: | :-----------------------: | :---------------: | :-------: |
86 | aarch64 (linux) | ✅ | ✅ (qemu-user[^qemu-user]) | ✅ (qemu[^qemu]) | ❌ |
87 | armhf (linux) | ✅ | ✅ (qemu-user[^qemu-user]) | ❌ | ❌ |
93 [^qemu-user]: qemu-aarch64-static or qemu-arm-static translate instructions into x86 and executes t…
94 host kernel. This works well for unit tests, but will fail when interacting with platform
98 emulation, which causes tests to be slow. Also not all aarch64 features are properly emulated,
99 which prevents us from running e2e tests.
