1.8.0

CHANGES:

• Add match_raises, a generalized version of check_raises
  (#88, #386, @JoanThibault)

• Update JaneStreet core and async to v0.16 (#390 @tmcgilchrist)

• Fix division by zero when size of the terminal is incorrectly
  reported as zero. (fix #356, #381, @MisterDA)

• Enable terminal size reporting on macOS and Windows. Also report the
  terminal size even when the test is run buffered by Dune.
  (#381, #396, @MisterDA)

• Allow overriding the number of columns with ALCOTEST_COLUMNS env
  var. (#322, #381, @MisterDA)

• Be able to allocate and use user's formatters for stdout/stderr
  (#399, @dinosaure)

• Stop detecting ocamlci specifically, since there's nothing specific
  about it. Simply use the CI env var to detect CIs. Improve CI
  detection.
  (#397, @MisterDA)

1.7.0

CHANGES:

• compile with MSVC (#369, @jonahbeckfordm review by @TheLortex
  and @MisterDA)

• Allow skipping a test case from inside the test case (#368, @apeschar)

• Fix compilation on bytecode architectures (#335, @glondu)

• Get alcotest_stubs.c to compile with MSVC (#369, @jonahbeckford)

• Try automatically reporting the location of calls to Alcotest.check.
  (#366, @MisterDA, review by @TheLortex)

• Detect that Alcotest is running in CI and change output accordingly.
  (#364, @MisterDA)

• Upgrade to dune >= 3.0. (#360, @MisterDA)

1.6.0

CHANGES:

• Fix a bug when running test concurently. Alcotest could fail to
  output the content of the log file. (#353, @hhugo)

• Require Cmdliner.1.1.0. (#339, @MisterDA)

• Upgrade to async>=v0.15.0 (#352, @crackcomm)

1.5.0

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. (#326 #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. (#317,
  @craigfe)

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

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

• Fix process for getting the width of attached terminals on MacOS.
  Previously, a terminal width of 80 columns was assumed. (#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. (#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. (#306,
  @craigfe)

• Change the ~filter argument to Alcotest.run to be a predicate over tests.
  (#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.
    (#306 #309, @craigfe)

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

1.4.0

CHANGES:

• Add ?here and ?pos arguments to the test assertion functions. These can be
  used to pass information about the location of the call-site, which is
  displayed in failing test output. (#291, @craigfe)

• Add a pretty-printer for the exception raised by Alcotest.check and related
  functions. This allows them to be used outside of an Alcotest test runner for
  making general assertions. (#296, @craigfe)

• Add --bail option (and corresponding ALCOTEST_BAIL environment variable),
  which causes Alcotest to terminate after the first test failure. (#298,
  @craigfe)

1.3.0

CHANGES:

• Add Alcotest.triple for testing 3-tuples. (#288, @sheepduke)

• Correctly report test suite duration with millisecond precision. (#286,
  @craigfe)

• Improve pretty-printing of results to consider the terminal width, fixing
  several display issues due to line wrapping in small terminals. (#282,
  @craigfe)

1.2.3

CHANGES:

• Require Dune 2.2. (#274, @craigfe)

• Fix a bug in the handling of the ~and_exit:false option when the test suite
  fails. (#271, @craigfe)

1.2.2

CHANGES:

• Fail gracefully when the user supplies an empty suite name. (#265, @craigfe)

• Fix compatibility with fmt.0.8.8+dune by adding a missing fmt dependency
  in alcotest's dune file (#266, @NathanReb)

• Only show "in progress" lines when writing to a TTY. (#267, @craigfe)

1.2.1

CHANGES:

• Surround pretty-printed diffs with quotes to make trailing whitespace more
  obvious. (#261, @craigfe)

• Allow . characters to appear unescaped in symlinks and test directories.
  (#259, @craigfe)

1.2.0

CHANGES:

• Add an alcotest-mirage package, allowing the construction of MirageOS
  unikernels that run Alcotest test suites. (#238, @hannesm @linse)

• Add Alcotest.check', a variant of Alcotest.check with labeled arguments.
  (#239, @hartmut27)

• Add a testable for the bytes type. (#253, @mefyl)

• Many assorted improvements to Alcotest output formatting. (#246, @craigfe)

• Default to --color=always when running inside Dune (#242, @craigfe). The
  value can be overridden by setting the ALCOTEST_COLOR variable in a dune
  file, for example:

(env
 (_
  (env-vars
   (ALCOTEST_COLOR auto))))

• Support all UTF-8 characters in test names and suite names, by normalising
  them for file-system interactions. (#249, @gs0510; #246, @craigfe)

• Fix various crashes when using non-filesystem-safe characters in test suite
  names (these break Alcotest when attempting to generate a corresponding log
  file). (#241, @mefyl; #246 @craigfe)
