// Change directories to the path of the ts-api-guardian source tree. We need to resolve an actual
// path of a tree because we want to determine the path to the directory that includes all
// test fixture runfiles. On Windows this is usually the original non-sandboxed disk location,
// otherwise this just refers to the runfile directory with all the proper symlinked files.
// NB: we resolve `test/fixtures/empty.ts` and then step up 3 folders so to ensure we resolve to the
//     root of the source tree and not the output tree on Windows where there are no runfiles.
// TODO: remove the whole bootstrap file once the tests are Bazel and Windows compatible.
