Running a Bazel executable target as a Bazel test?

Question

I have a Bazel executable target (of type fsharp_binary, but I don't think it should matter) that I can run using bazel run.

bazel run //my_app.exe

I would like to use this executable as a test, so that when I call bazel test it gets built and executed, and a non-zero exit code is considered a test failure.

bazel test //...

What I am looking for is something like this:

test_of_executable(
  name = "my_test",
  executable = "//my_app.exe",
  success_codes = [ 0 ],
)

Then:

bazel test //:my_test

How can I achieve this in Bazel?

Just wrap your app as a sh_test. See for example https://github.com/bazelbuild/bazel/issues/1969.

What I use in my codebase is:

BUILD.bazel:

sh_test(
    name = "test",
    srcs = ["test.sh"],
    data = [
        "//:some_binary",
    ],
)

test.sh

some_project/some_subdir/some_binary

See here for an real example.
