1.3.0

Deprecate the whole library.
Avoid using assertion libraries.
Use the standard library and github.com/google/go-cmp/cmp instead.
Follow the official Go Test Comments.

1.2.0

Added

• Add FailureMessage.Err method together with AssertionError type to represent assertion results as error type.

New Contributors

• @lycis made their first contribution in #141

1.1.0

The main additions are the new assertions for bool, constraints.Ordered, constraints.Float, constraints.Integer, string, error, []T, map[K]V, func() types.

Added

• Add True, False, assertion functions.
• Add Nil, NotNil, assertion functions.
• Add NoError, IsError assertion functions.
• Add Panics, NoPanic assertion functions.
• Add Eventually, EventuallyChan assertion functions.
• Add Ordered function which provides following assertions, in addition to Comparable, via FluentOrdered type:
  • Lesser
  • LesserOrEqual
  • GreaterOrEqual
  • Greater
• Add String function which provides following assertions, in addition to Ordered, via FluentString type:
  • Empty
  • NotEmpty
  • Contain
  • NotContain
  • Prefix
  • NoPrefix
  • Sufix
  • NoSufix
  • EqualFold
  • NotEqualFold
  • MatchRegex
  • NotMatchRegex
• Add Number function which provides following assertions, in addition to Ordered, via FluentNumber type:
  • InDelta
  • NotInDelta
  • InEpsilon
  • NotInEpsilon
• Add Error function which provides following assertions, in addition to Any and String (for error message), via FluentObj and FluentString types:
  • Is
  • IsNot
  • As
  • NotAs
• Add Slice function which provides following assertions, in addition to Any, via FluentSlice type:
  • Empty
  • NotEmpty
  • Equivalent
  • NotEquivalent
  • Contain
  • NotContain
  • Any
  • All
  • None
• Add Map function which provides following assertions, in addition to Any, via FlientMap type:
  • Empty
  • NotEmpty
  • Contain
  • NotContain
  • ContainPair
  • NotContainPair
  • Any
  • All
  • None
• Add FailureMessage.Prefix method together with And and Or functions to facilitate creating complex assertions.

Changed

• The f package is renamed to verify.
• Rename Obj and FluentObj to Any and FluentAny.
• Rename Comparable and FluentComparable to Obj and FluentObj.
• Change the Check assertion for any object so that the provided function has to return FailureMessage instead of a string.
• Zero and NonZero methods are moved to FluentComparable.
• Better failure messages.

1.0.0-rc.3

Removed

• Remove constraints package.

1.0.0-rc.2

Changed

0.2.0

This release is a complete rewrite. It is not compatible with the previous release.

The new API is type-safe and easier to extend.

The next release is supposed to provide assertions for constraints.Ordered, string, error, []T, map[K]V, func().

Added

• Add FailureMessage which encapsulates the failure message and methods for error reporting.
• Add Obj function which provides following assertions via FluentObject type:
  • Check
  • Should
  • ShouldNot
  • DeepEqual
  • NotDeepEqual
  • Zero
  • NonZero
• Add Comparable function which provides following assertions,
  in addition to Obj, via FluentComparable type:
  • Equal
  • NotEqual

Changed

• Require Go 1.18.

Fixed

• Fix error reporting line (use t.Helper() when available).

Removed

• Remove all previous functions and types (API rewrite).

0.1.0

First release after the experiential phase.

Added

• Add f.Assert that can be used instead of t.Error methods.
• Add f.Require that can be used instead of t.Fatal methods.
• Add Should assertion that can be used with custom predicates.
• Add Eq assertion that checks if got is deeply equal to want.
• Add Nil assertion that checks if got is nil.
• Add Err assertion that checks if got is an error.
• Add Panic assertion that checks if calling got results in a panic.
• Add NoPanic assertion that checks if calling got returns without panicking.
