[new release] alcotest, alcotest-async, alcotest-js, alcotest-mirage and alcotest-lwt (1.5.0)

[craigfe]

Alcotest is a lightweight and colourful test framework

• Project page: https://github.com/mirage/alcotest
• Documentation: https://mirage.github.io/alcotest

CHANGES:

• Make Alcotest compatible with js_of_ocaml.3.11.0. Users can depend on the
  new virtual alcotest-js Opam library to pick up the right js_of_ocaml
  version automatically. (Add jsoo support, configure CI mirage/alcotest#326 Add a virtual alcotest-js package for JavaScript dependencies mirage/alcotest#328, @hhugo @smorimoto)

• Record exception backtraces during test suite runs by default. This behaviour
  can be disabled by passing ~record_backtrace:false to Alcotest.run. (Record exception backtraces during test suite runs mirage/alcotest#317,
  @craigfe)

• Generate shorter unique identifiers for test runs (8-character alphanumeric,
  rather than a full 128-bit UUID). (Use shorter random IDs for test runs mirage/alcotest#304, @craigfe)

• Change Alcotest.{char,string} pretty-printers to use OCaml syntax on
  assertion failures (i.e. wrap with quotes and escape control characters).
  (Print strings and chars with OCaml syntax on assertion failures mirage/alcotest#318, @craigfe)

• Fix process for getting the width of attached terminals on MacOS.
  Previously, a terminal width of 80 columns was assumed. (Fix bindings to TIOCGWINSZ on MacOS mirage/alcotest#325, @craigfe)

• Fix parsing of test filter ranges to allow '-' separators (e.g. test alpha 1-4), as advertised in the manpage. The previously-used '..' separator is
  also supported. (Fix the processing of test filter ranges to match the documentation mirage/alcotest#312, @craigfe)

• Introduce an Alcotest.V1 module that aliases the existing Alcotest API and
  provides a stability guarantee over major version changes. Similar versioned
  aliases also exist for the backends: Alcotest_{async,lwt}.V1. (Introduce a versioned API for Alcotest V1 mirage/alcotest#306,
  @craigfe)

• Change the ~filter argument to Alcotest.run to be a predicate over tests.
  (Change the ~filter test selector to be a predicate mirage/alcotest#305, @craigfe)

• Renamed / removed some less frequently used modules used by the test backends:

  • Alcotest.Unix -> Alcotest.Unix_platform
  • Alcotest_engine.{Cli,Core,Test} -> Alcotest_engine.V1.{Cli,Core,Test}
  • Alcotest.{Cli,Core} are now gone. Use Alcotest_engine.V1.{Cli,Core}.Make (Alcotest.Unix_platform) instead.
    (Introduce a versioned API for Alcotest V1 mirage/alcotest#306 Provide versioned aliases for the Async and Lwt backends mirage/alcotest#309, @craigfe)

• Avoid exporting list_tests in the main test APIs (Alcotest{,_lwt,_async}).
  Use Alcotest_engine directly if you want this function. (Avoid exporting list_tests in the main test APIs mirage/alcotest#310, @craigfe)

I believe the remaining CI failures are unrelated to this release.

CC @c-cube for the change to qcheck-alcotest.0.18 dependencies.
