Release Notes

The ReportLogExtension vestiges were removed. As this extension was mostly used for an unreleased Spock module, this won’t affect many users. If you are using a Spock Configuration File with a report section, then you must delete everything from this section except for issueNamePrefix and issueUrlPrefix. These two properties are still supported and used by the @Issue extension.

Add support for injection into @Shared fields in spock-spring module which users can opt-in for by adding @EnableSharedInjection to the specification. #76

Add new displayName via INameable for SpecInfo, FeatureInfo, and IterationInfo. This field can be set via extensions to change the reported name. The existing iteration NameProvider now also sets the displayName instead of the name. Modifying the name instead of displayName is now considered deprecated for extensions. #1236

Add support for constructor injection for extensions

Improve final field handling. Final fields are now transformed similar to shared fields, so that we can still delay the initialization but keep them unmodifiable to user code. #1011

Improve parallel extensions to support inheritance #1245

Improve PollingConditions

Improve some AST transformation code regarding error handling

Deprecate AbstractGlobalExtension and replace with IGlobalExtension

Remove unnecessary try-finally construct for assertions

Fix ErrorSpecNode throw Exception in prepare instead of execute this fixes an issue that interceptors for prepare, before, and around were still executed and any Exception they throw would hide the actual cause.

Fix #1294 swallowing of unrecoverable Errors

Fix #1260 Change InteractionRewriter to keep casting of ListExpressions intact

Fix #1282 Make TempDirInterceptor safe for parallel invocation of iterations

Fix #1267 Retry extension behavior for unrolled tests

Fix #1267 Retry extension behavior for unrolled tests

Fix #1229 @TempDir not working for inherited fields

Fix #1232 compile error for nested conditions without top-level condition

Fix #1256 handling of is as getter for boolean properties on Mocks

Fix #1270 handling of is as getter for boolean properties on GroovyMocks

Fix ErrorSpecNode to re-throw Exception in prepare instead of execute, this fixes an issue that interceptors for prepare, before, and around were still executed and any Exception they throw would hide the actual cause.

Fix #1263 ExceptionAdapterExtension to also handle inherited fixture methods

Fix #1279 Cast data variables with type coercion to the declared parameter type

A new MutableClock utility class to support time related testing, see docs.

Defining interactions on property getters within Mock instantiation closures or with closures works now without the need to explicitly qualify the property access with it.:

Foo foo = Stub {
    bar >> 'my stubbed property'
}

A sequence of two or more underscores can be used to separate multiple data tables in one where block.

Type casts in conditions are now properly carried over to properly disambiguate method calls. For more information see issue #1022.

Data tables now support any amount of semicolons to separate data table columns as alternative to pipes and double pipes, but cannot be mixed with them in one table:

where:
a ; b ;; c
1 ; 2 ;; 3

The default unroll pattern changed from the rather generic #featureName[#iterationIndex] to a more fancy version that lists all data variables and their values additionally to the feature name and iteration index. If you prefer to retain the old behaviour, you can set the setting unroll { defaultPattern '#featureName[#iterationIndex]' } in the Spock configuration file and you will get the same result as previously.

If neither a parameter to the @Unroll annotation is given, nor the method name contains a #, now the configuration file setting unroll { defaultPattern } is inspected. If it is set to a non-null string, this value is used as unroll pattern.

IterationInfo now has a property for the iterationIndex and one for a map of data variable names to values. This is typically not interesting for the average user, but might be helpful for authors of Spock extensions.

constructorArgs now properly transport type cast information to the constructor selection, for example to disambiguate multiple candidate constructors:

Spy(constructorArgs: [null as String, (Pattern) null])

Accessing previous data table columns was broken in some cases, now it should work properly, even cross-table and without being disturbed by previous derived data variables.

The order of parameters in a data-driven feature does no longer have to be identical to the declaration order in the where block. Data variables are now injected by name.

Data driven features do no longer have the requirement that either none or all data variables are declared as parameters and that all parameters are also data variables. Now you can either declare none, some, or all data variables as parameters and also have additional method parameters that are no data variables. Those additional parameters must be provided by some Spock extension though. If they are not set at execution time, an exception will be thrown.

Condition closures used in @Requires, @IgnoreIf and @PendingFeatureIf now also get the context passed as argument, so you can use this, typed as org.spockframework.runtime.extension.builtin.PreconditionContext to enable IDE support like code completion:

@IgnoreIf({ PreconditionContext it -> it.os.windows })
def "I'll run everywhere but on Windows"() { ... }

Execution with an unsupported Groovy version can be allowed with -Dspock.iKnowWhatImDoing.disableGroovyVersionCheck=true (#1164)

Relax maximum allowed Groovy version in snapshot builds (#1108)

Upgrade Groovy to 2.5.12 (improved Java 14+ support) and 3.0.4 (fixes #1127)

Upgrade JUnit 4 to 4.13 (in spock-junit4)

Upgrade Hamcrest to 2.2 (from 1.3 provided previously by junit4.jar)

Derived data variables (assignments in where blocks) now also support multi-assignment syntax, including ignoring some values with the wildcard expression.

(a, b, _, c) = row

Multi-variable data pipes now also support nesting.

[a, [_, b]] << [
  [1, [5, 1]],
  [2, [5, 2]]
]

The condition closures for @IgnoreIf, @Requires and @PendingFeatureIf can now access data variables if applied to a data driven feature. This has further implications that are documented in the respective documentation parts and JavaDocs.

Data driven features are now unrolled by default. @Unroll can still be used to specify a custom naming pattern. A simple @Unroll without argument is not needed anymore except when undoing a spec-level @Rollup annotation or if unrolling by default is disabled, so any simple @Unroll annotations can be removed from existing code. You can verify this by looking at the test count which should not have been changed after you removed the simple @Unroll annotations.

@Rollup can now be used on feature and spec level to explicitly roll up any feature where the reporting of single iterations is not wanted.

The setting unroll { unrollByDefault false } in the Spock configuration file can be set to roll up all features by default if not overwritten by explicit @Unroll annotations and thus reinstate the pre Spock 2.0 behaviour.

The verifyAll method can be used to assert multiple boolean expressions without short-circuiting those after a failure. For example:

Detached mocks via the DetachedMockFactory and SpockMockFactoryBean classes see the Spring Module Docs.

Cells in a data table can refer to the current value for a column to the left.

Spy can be used to create partial mocks for Java 8 interfaces with default methods just as it can for abstract classes.

Improved power assert output when an exception occurs evaluating an assertion.

A new @PendingFeature annotation to distinguish incomplete functionality from features with @Ignore.

17 contributors, 21 resolved issues, 18 merged pull requests, some ongoing work. No ground-breaking new features, but significant improvements and fixes across the board.

Minimum runtime requirements raised to JRE 1.6 and Groovy 2.0.

Improved and restyled reference documentation at http://docs.spockframework.org. Generated with Asciidoctor (what else?).

Maven plugin removed. Just let Maven Surefire run your Spock specs like your JUnit tests (see spock-example project).

Official support for Java 1.8, Groovy 2.3 and Groovy 2.4. Make sure to pick the groovy-2.0 binaries for Groovy 2.0/2.1/2.2, groovy-2.3 binaries for Groovy 2.3, and groovy-2.4 binaries for Groovy 2.4 and higher.

Improved infrastructure to allow for easier community involvement: Switch to GitHub issue tracker, Windows and Linux CI builds, pull requests automatically tested, all development on master branch (bye-bye groovy-x.y branches!).
