Package pidonetest provides a simple way for running go tests in an isolated system. It requires QEMU to be present on the system. Depending on the presence of GOARCH or the runtime arch, the correct qemu-system binary and machine type is used. KVM is enabled if present and accessible. Those things can be overridden by flags. See "pidonetest -help" for all flags. The easiest way to use this package is to use the default mode. This does not need any special support by your test package. The downside is, that it can only be used if the target architecture matches the pidonetest binary architecture. See "Library" if you want to test for different architectures. If the kernel used does not have support for Virtio-MMIO compiled in, use flag "-transport 0" in order to use legacy isa-pci serial consoles for IO. Set absolute path to the kernel to use by environment variable: If you have it installed with go install in your PATH: Or build and run on the fly with "go run": There is also support for coverage profiles. Just specify it as usual: In Standalone mode, the test binary can be used as init binary directly. For this to work, the init steps need to be compiled in. this is done by defining your own TestMain function using the provided package as library. The library part is a wrapper for testing.M.Run. Before running the tests some special system file systems are mounted, like /dev, /sys, /proc, /tmp, /run, /sys/fs/bpf/, /sys/kernel/tracing/. In a test package, define your custom TestMain function and call pidonetest.RunTests. You may keep this in a separate test file and use build constraints in order to have an easy way of separating such test from normal go tests that can run on the same system: See the selftest directory for a working example. Instead of using pidonetest.RunTests you can use call the various parts individually, of course, and just mount the file systems you need or additional ones. See pidonetest.RunTests for the steps it does. With the TestMain function in place, run the test and specify the pidonetest binary in one of the following ways. If the test binary is dynamically linked libraries are resolved. However, if you run into errors try again with "CGO_ENABLED=0", if you don't need cgo. In any case, make sure the QEMU binary used has the same architecture as the test binary. If you have it installed with go install in your PATH: Or build and run on the fly with "go run": There is also support for coverage profiles. Just specify it as usual: Other architectures work as well. You need a kernel for the target architecture.
