CHANGELOG.md

1.15.0

Fixes

The previous version (1.14.0) introduced a change to allow Eventually and Consistently to support functions that make assertions. This was accomplished by overriding the global fail handler when running the callbacks passed to Eventually/Consistently in order to capture any resulting errors. Issue #457 uncovered a flaw with this approach: when multiple Eventuallys are running concurrently they race when overriding the singleton global fail handler.

1.15.0 resolves this by requiring users who want to make assertions in Eventually/Consistently call backs to explicitly pass in a function that takes a Gomega as an argument. The passed-in Gomega instance can be used to make assertions. Any failures will cause Eventually to retry the callback. This cleaner interface avoids the issue of swapping out globals but comes at the cost of changing the contract introduced in v1.14.0. As such 1.15.0 introduces a breaking change with respect to 1.14.0 - however we expect that adoption of this feature in 1.14.0 remains limited.

In addition, 1.15.0 cleans up some of Gomega's internals. Most users shouldn't notice any differences stemming from the refactoring that was made.

1.14.0

Features

• gmeasure.SamplingConfig now suppers a MinSamplingInterval [e94dbca]
• Eventually and Consistently support functions that make assertions [2f04e6e]
  • Eventually and Consistently now allow their passed-in functions to make assertions. These assertions must pass or the function is considered to have failed and is retried.
  • Eventually and Consistently can now take functions with no return values. These implicitly return nil if they contain no failed assertion. Otherwise they return an error wrapping the first assertion failure. This allows these functions to be used with the Succeed() matcher.
  • Introduce InterceptGomegaFailure - an analogue to InterceptGomegaFailures - that captures the first assertion failure and halts execution in its passed-in callback.

Improvements:

• The Equal matcher matches byte slices more performantly.
• Improved how MatchError matches error strings.
• MatchXML ignores the order of xml node attributes.
• Improve support for XUnit style golang tests. (#254)

Bug Fixes:

• Diff generation now handles multi-byte sequences correctly.
• Multiple goroutines can now call gexec.Build concurrently.

1.2.0

Improvements:

• Added BeSent which attempts to send a value down a channel and fails if the attempt blocks. Can be paired with Eventually to safely send a value down a channel with a timeout.
• Ω, Expect, Eventually, and Consistently now immediately panic if there is no registered fail handler. This is always a mistake that can hide failing tests.
• Receive() no longer errors when passed a closed channel, it's perfectly fine to attempt to read from a closed channel so Ω(c).Should(Receive()) always fails and Ω(c).ShoudlNot(Receive()) always passes with a closed channel.
• Added HavePrefix and HaveSuffix matchers.
• ghttp can now handle concurrent requests.
• Added Succeed which allows one to write Ω(MyFunction()).Should(Succeed()).
• Improved ghttp's behavior around failing assertions and panics:
  • If a registered handler makes a failing assertion ghttp will return 500.
  • If a registered handler panics, ghttp will return 500 and fail the test. This is new behavior that may cause existing code to break. This code is almost certainly incorrect and creating a false positive.
• ghttp servers can take an io.Writer. ghttp will write a line to the writer when each request arrives.
• Added WithTransform matcher to allow munging input data before feeding into the relevant matcher
• Added boolean And, Or, and Not matchers to allow creating composite matchers
• Added gbytes.TimeoutCloser, gbytes.TimeoutReader, and gbytes.TimeoutWriter - these are convenience wrappers that timeout if the underlying Closer/Reader/Writer does not return within the alloted time.
• Added gbytes.BufferReader - this constructs a gbytes.Buffer that asynchronously reads the passed-in io.Reader into its buffer.

Bug Fixes:

• gexec: session.Wait now uses EventuallyWithOffset to get the right line number in the failure.
• ContainElement no longer bails if a passed-in matcher errors.

1.0 (8/2/2014)

No changes. Dropping "beta" from the version number.

1.0.0-beta (7/8/2014)

Breaking Changes:

• Changed OmegaMatcher interface. Instead of having Match return failure messages, two new methods FailureMessage and NegatedFailureMessage are called instead.
• Moved and renamed OmegaFailHandler to types.GomegaFailHandler and OmegaMatcher to types.GomegaMatcher. Any references to OmegaMatcher in any custom matchers will need to be changed to point to types.GomegaMatcher

New Test-Support Features:

• ghttp: supports testing http clients
  • Provides a flexible fake http server
  • Provides a collection of chainable http handlers that perform assertions.
• gbytes: supports making ordered assertions against streams of data
  • Provides a gbytes.Buffer
  • Provides a Say matcher to perform ordered assertions against output data
• gexec: supports testing external processes
  • Provides support for building Go binaries
  • Wraps and starts exec.Cmd commands
  • Makes it easy to assert against stdout and stderr
  • Makes it easy to send signals and wait for processes to exit
  • Provides an Exit matcher to assert against exit code.

DSL Changes:

• Eventually and Consistently can accept time.Duration interval and polling inputs.
• The default timeouts for Eventually and Consistently are now configurable.

New Matchers:

• ConsistOf: order-independent assertion against the elements of an array/slice or keys of a map.
• BeTemporally: like BeNumerically but for time.Time
• HaveKeyWithValue: asserts a map has a given key with the given value.

Updated Matchers:

• Receive matcher can take a matcher as an argument and passes only if the channel under test receives an objet that satisfies the passed-in matcher.
• Matchers that implement MatchMayChangeInTheFuture(actual interface{}) bool can inform Eventually and/or Consistently when a match has no chance of changing status in the future. For example, Receive returns false when a channel is closed.

Misc:

• Start using semantic versioning
• Start maintaining changelog

Major refactor:

• Pull out Gomega's internal to internal
