Changes to our Filesystem Test Suite

[Chris Suter]

Hi folks,

Some changes have landed recently that mean it's now possible to easily run the filesystem test suite against filesystem implementations (including out-of-tree implementations).

It should be as simple as adding something like:

import("//src/storage/fs_test/suite.gni")

 

fs_test_suite("anyfs") {

  # The dependencies should include the filesystem binary.

  deps = [ ":anyfs_bin" ]

  config = {

    timestamp_granularity = 1

    supports_hard_links = true

    supports_resize = true

    max_file_size = 9223372036854775807

  }

}

to your BUILD.gn file. See https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/src/storage/fs_test/suite.gni. The schema for the configuration can be found here: https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/src/storage/fs_test/fs_test.schema.json. The name and binary_path properties will be derived if not specified. It should be possible to enable or disable most tests depending on what might be supported by a filesystem. There are examples of its use to be found in https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/src/storage.

The schema of the config and other aspects of the template are subject to change so shouldn't be considered stable (yet).

Feedback is welcome.

Cheers,

Chris
