Changes in 1.4.0

  • We now have a manual at http://hspec.github.io/. The sources are in doc/. It's still work in progress. Contributions are very welcome!
  • The Haddock documentation now indicates the stability of each exposed module. Test.Hspec is now considered stable.

    • --re-run only runs spec items that previously failed. This is undocumented, experimental and only works within GHCi (use :reload / :main)!
  • Runner functions exported from Test.Hspec.Runner new expect a monadic spec.
  • fromHUnitTest has been added. It can be used to run existing HUnit test suites with Hspec.
  • The Example instance for HUnit Tests has been deprecated. fromHUnitTest can be used instead. The primary motivation is, that fromHUnitTest gives more detailed reporting for nested HUnit test suites.
  • Test.Hspec.Monadic has been deprecated, all functionality is available through one of Test.Hspec, Test.Hspec.Core or Test.Hspec.Runner.
  • More of Hspec's internals are now exposed from Test.Hspec.Core
  • All runner functions for the core spec type (aka as non-monadic spec) have been deprecated, use e.g. Test.Hspec.hspec . fromSpecList instead. The motivation is to provide an API that does not expose colliding names.
  • Some other stuff from Test.Hspec.Core that collides with other parts of the API has been deprecated. Compatible alternatives are given in each deprecation message.
  • The default formatter now produces less whitespace (#73) + other minor improvements
  • The formatter API has been revamped.
  • The exception type is now printed if an example fails due to an exception (#50)
  • The number of pending examples is now printed after each test run (#85)
  • --verbose has been added (#87)

Changes in 1.3.0

  • Test.Hspec now re-exports the monadic API. If you still use the non-monadic API, you can use Test.Hspec.Core as a drop-in replacement.

  • hspec-expectations, a set of combinators that allow to express expectations about the outcome of code examples, is now included with Hspec. Have a look at the [README of hspec-expectations] (https://github.com/sol/hspec-expectations#readme) for a short introduction.

  • hspec-discover, a mechanism for automatic spec discovery, is now an official part of Hspec. Have a look at [hspec-discover's README] (https://github.com/hspec/hspec/tree/master/hspec-discover#readme) for a short introduction.

Changes in 1.2.0

  • hspec has been removed, and hspecX has been renamed to hspec (see #71)

  • hHspec now returns a summary of the test run.

  • The time reporting after a test run is not colored anymore.

Changes in 1.1.3

  • Test.Hspec warns now about future changes: It will re-export Test.Hspec.Monadic in the future. If you still use the non-monadic API, you can either use Test.Hspec.Core as a drop-in replacement, or migrate your code to the monadic API.

    The monadic API is more stable and easier to use. Now is a good time to switch!

  • Test.Hspec.Core is now a proper superset of Test.Hspec

Changes in 1.1.2

  • All descriptions of nested examples are now included in summary for failing examples

  • context is now an alias for describe

Changes in 1.1.1

  • Specs from Test.Hspec.Monadic has been renamed to Spec. For backward compatibility Specs is still kept as an alias.

Changes in 1.1.0

The reason for pending examples is now optional

With this change, both of the following code snippets work.

it "some behavior" $
  pending  -- no reason given
it "some other behavior" $
  pending "some reason"

Hspec does not rely on ExistentialQuantification anymore

The type used to represent specs is now abstract

This should give more useful error messages when adapting old specs that use the non-monadic API for hspec-1.0/hspec-1.1.

Several internal types and functions have been deprecated

Those are internal functions, and they will be removed/hidden with the next release. If you use any of those, update your code. If you really need them, open a ticket and describe your use case.

Changes in 1.0.0

Hspec now re-uses QuickCheck's property function

Test.Hspec.QuickCheck.property is now simply a re-exports of Test.QuickCheck.property. This has the advantage that you do not get a name collision if you import both, Test.Hspec.QuickCheck and Test.QuickCheck.

Better support for nested specs

NOTE: This is a breaking change to the non-monadic API. The monadic API is not affected.

In some situations parent descriptions for nested specs were not included in the generated report. Solving this required a change to the data structure that is used to represent specs (it was not a proper tree, now it is).

Updating specs that use the non-monadic API

The runner functions (hspec, hspecB and hspecX) now take a list of descriptions.

The following works with hspec-0.9, but not with hspec-1.0.

main = hspecX $
  describe "reverse" [
    it "reverses a list" $
      reverse [1, 2, 3] == [3, 2, 1],

    it "gives the original list, if applied twice" $ property $
      \xs -> reverse (reverse xs) == (xs :: [Int])
  ]

For hspec-1.0, you need to wrap it into a list.

main = hspecX [
    describe "reverse" [
      it "reverses a list" $
        reverse [1, 2, 3] == [3, 2, 1],

      it "gives the original list, if applied twice" $ property $
        \xs -> reverse (reverse xs) == (xs :: [Int])
    ]
  ]

Specs consisting of several desribes, combined with descriptions, continue to work unchanged. But descriptions is now a noop, and it will be removed in a future release. So it is a good idea to drop it.

The following works with both hspec-0.9 and hspec-1.0.

main = hspecX $ descriptions [  -- descriptions is redundant
    describe "Foo" [
      it "has some behavior" True
    ]
  , describe "Bar" [
      it "has some behavior" True
    ]
  ]

But the following is recommended instead.

main = hspecX [
    describe "Foo" [
      it "has some behavior" True
    ]
  , describe "Bar" [
      it "has some behavior" True
    ]
  ]

A new monadic API for custom Formatters

For all the details, have a look at the [docs] (http://hackage.haskell.org/packages/archive/hspec/latest/doc/html/Test-Hspec-Formatters.html).

The total time required to run a spec is now included in the summary

In addition to the used CPU time, the total time required to run a spec is now include in the summary. This is useful for specs that do non-CPU-intensive stuff, or fork subprocesses.
