Module documentation for 2.3.4

Used by 2 packages in nightly-2021-07-06(full list with versions):
crackNum, tasty-golden

This package provides support for «golden testing». A golden test is an IO action that writes its result to a file. To pass the test, this output file should be identical to the corresponding «golden» file, which contains the correct result for the test. To get started with golden testing and this library, see Introduction to golden testing.

Changes

Changes

Version 2.3.4

  • Add an option to remove the output file after a test has run, if there is a golden file, or one has been created

Version 2.3.3.3

  • Fix a bug where goldenVsFileDiff would not create a missing golden file

Version 2.3.3.2

  • Fix a bug where the TASTY_SIZE_CUTOFF env. variable would be ignored

Version 2.3.3.1

  • Fix a bug with UTF-8 output

Version 2.3.3

  • Expose createDirectoriesAndWriteFile
  • Add --size-cutoff to truncate large golden test output
  • Restore support for GHC >= 7.8

Version 2.3.2.1

Create missing directories when writing golden files

Version 2.3.2

Add a --no-create flag

Version 2.3.1.3

Make the environment variable TASTY_ACCEPT=True work, and make the value case-insensitive (so TASTY_ACCEPT=true works, too)

Version 2.3.1.2

Docs: link to an introductory blog post

Version 2.3.1.1

Fix compatibility with optparse-applicative-0.13

Version 2.3.1

Intercept exceptions thrown by the test, adhering to the new tasty API contract.

Version 2.3.0.2

Switch from temporary-rc to temporary

Version 2.3.0.1

Impose a lower bound version constraint on bytestring.

Version 2.3

  • Accepting tests is no longer done by a separate ingredient; instead it is now an option that affects tests themselves.

    • --accept used to run only golden tests; now all tests are run, but only golden tests are affected by this option
    • when accepting, all the usual options apply (such as -j)
    • when accepting, the interace is the same as when running
    • defaultMain and acceptingTests are kept for compatibility, but do not do anything and are obsolete

  • When a golden test file does not exist, it is created automatically, even when --accept is not specified. You’ll see a message like

      UnboxedTuples:                 OK (0.04s)
    Golden file did not exist; created

  • No longer use lazy IO

    • ValueGetter type is gone (replaced by IO)
    • Because of that, the type of the primitive goldenTest is changed
    • vgReadFile function is gone (replaced by Data.ByteString.readFile)

Version 2.2.2.4

  • Warn when some tests threw exceptions during --accept
  • Properly handle exceptions; don’t swallow Ctrl-C

Version 2.2.2.3

Restore compatibility with older compilers

Relax Cabal dependency

Version 2.2.2

Add findByExtension

Version 2.2.1.2

Version 2.2.1

  • Fix a bug where the result of the comparison function would reference yet unread data from a semiclosed file and the file gets closed, leading to a runtime exception
  • Export writeBinaryFile
  • Improve the docs
  • Update to work with tasty-0.8
