  2. Docs
Mirage implementation for Alcotest






1.7.0 (2023-02-24)

  • 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 (2022-06-24)

  • Fix a bug when running test concurrently. 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 (2021-10-09)

  • 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 (#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 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 (2021-04-15)

  • 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 (2021-02-16)

  • 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 (2020-09-07)

  • 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 (2020-08-26)

  • 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 (2020-07-15)

  • 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)

  • 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:

   (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)

1.1.0 (2020-04-03)

  • Fix handling of CLI options for Alcotest_{async,lwt}.run. (#222, @CraigFe)

  • Fix interleaving of ASSERT outputs with the other test code, and ensure that it is correctly captured in log files. (#215 #228, @icristescu @CraigFe)

  • Don't raise Test_exception on Cmdliner parse failure (#234, @CraigFe)

1.0.1 (2020-02-12)

  • Add support for an ALCOTEST_COLOR={auto,always,never} environment variable to control the colorization of terminal output. (#209, @mjambon)

  • Fix handling of exceptions in Alcotest_{async,lwt}. (#212, @CraigFe @talex5)

1.0.0 (2020-01-14)

  • Require OCaml 4.03. (#159, @hannesm)

  • Change Alcotest_{async,lwt}.test_case to return monadic values. These must be run with the new Alcotest_{async,lwt}.run functions. See examples/lwt/ for an example of the new API. (#167, @CraigFe)

  • Add generation of latest symlinks in the _test directory which point to the most recent test output directory. (#155, @cfcs)

  • Allow all CLI options to be passed directly to Alcotest.{run,run_with_args} without use of the argv parameter. (#182, @CraigFe)

  • Add --compact option for more concise result reporting. (#149, @andersfugmann)

  • Add --tail-errors option for limiting the size of error logs printed to standard output. (#200, @mjambon)

  • Add support for executing subsets of tests via the test subcommand. (#158, @CraigFe)

  • Reject test suites with colliding output directories. (#176, @CraigFe)

  • Restrict the set of characters allowed in test names to alphanumerics, hyphens, underscores and spaces. (#161, @CraigFe)

  • Fix a race condition on creating output directories. (#150, @edwintorok)

  • Report test suite durations in real time rather than system time. (#162, @CraigFe)

  • Improve documentation of the ?argv parameter. (#164, @ian-barnes)
