[0.28.1] 2024-04-17

Added

• Added core wasmWasi support, wasmJs to coroutines

[0.28.0] 2023-12-05

Changed

• Minimum supported kotlin version is 1.9.21
• Rename isSameAs/isNotSameAs to isSameInstanceAs/isNotSameInstanceAs to make it more clear they
  use are about instance identity, old name is deprecated
• Rename containsAll to containsAtLeast to make it more clear that the collection can contain additional elements,
  old name is deprecated
• Bytes are shown as hex on all supported platforms (previously it was only on the jvm)
• If isEqualTo fails and the expected and actual display the same string, print a disambiguation message, ex:

  expected:<4> with type:<class kotlin.Int> but was type:<class kotlin.Short> with the same string representation
  

Breaking Changes

• Binary-breaking change as previous error-level deprecations were removed

Added

• Added doesNotContainKey assertion for Map

Fixed

• Fixed incorrect usage of contains in some kdoc examples
• Exceptions being swallowed if thrown in a soft assertion block
• More correctly re-throw fatal error in the jvm

[0.27.0] 2023-09-13

Changed

• Minimum supported kotlin version is 1.9.0
• Added support for WASM targets (note: this only applies to the core library
  and not assertk-coroutines as the coroutines library doesn't have a stable
  release for it yet)

Breaking Changes

• Previous assertThat {} deprecation warning is now an error

[0.26.1] 2023-05-18

Fixed

• Made assertFailure {} inline like assertThat {} was to allow testing suspend function failures.

[0.26] 2023-05-12

Changed

• Minimum supported kotlin version is 1.8.10
• Minimum supported coroutines version is 1.7.0
• When asserting on a Throwable or failed Result, their exception is added as the cause to any
  AssertionErrors which are thrown as the result of an assertion failure.
• Removed second type parameter on Any.isInstanceOf extension. In practice this would generally widen
  to Any which is what it has been replaced with.

Breaking Changes

• Previous deprecations are now errors

Added

• Added assertFailure { } entrypoint which is a shorthand for assertThat(runCatching { .. }).isFailure()
• Added first and single assertion for Iterable
• Added containsMatch assertion for CharSequence.
  Unlike 'contains' this is a regex rather than a literal.
  Unlike 'matches' this looks for a subset of the CharSequence to match rather than the entire contents.
• Added reified overloads of hasClass, doesNotHaveClass, isInstanceOf, and isNotInstanceOf.
  For example: isInstanceOf<String>().
• Added sequence assertions to mirror iterable
• Added array assertions for UByteArray, UShortArray, UIntArray, and ULongArray.

Deprecated

• Lambda-accepting assertThat { } entrypoint is now deprecated.
  Use assertThat(T) for normal values or assertFailure { } for exception-throwing code.

Fixed

• Fixed iterable assertions that take a block that could have multiple assertions.
  Includes: none,atLeast,atMost,exactly, and any

[0.25] 2021-09-12

Changed

• Minimum supported kotlin version is 1.5.30
• Minimum supported coroutines version is 1.5.2
• Replaced custom result type returned from assertThat {} with kotlin.Result. This is a binary-incompatible change,
  but it should be source-compatible in most cases as referencing the custom result type directly was discouraged.

Added

• Added startsWith() and endsWith() for List.
• Added Optional<>.isPresent(), Optional<>.isEmpty(), Optional<>.hasValue()
• Added expanded set of apple targets for kotlin native.

Fixed

• Fixed behavior of isEqualToIgnoringGivenProperties to only check accessible properties.
• Added prop which can take a member function. This restores much of the functionality deprecated
  in 0.23, while preserving the useful type-safety of the new overloads.

[0.24] 2021-05-05

Fixed

• Fixed any breaking when the list had several items.

Added

• Added containsSubList for List.
• Added exists for Path.

[0.23.1] 2021-02-03

Fixed

• Fixed containsExactly failing on custom list types.
• Fixed NullPointerException in isDataClassEqualTo when a property is null.
• Fixed multiple failures breaking any
• Fixed map's containsOnly to ensure keys match up with values.
• Fixed map's contain methods null handling.

Changed

• Minimum supported kotlin version is 1.4.0
• Multiplatform artifacts are published as a single artifact. You can now just write

  sourceSets {
    commonTest {
      dependencies {
         implementation "com.willowtreeapps.assertk:assertk:..."
      }
    }
  }

instead of defining one for each platform.

• Added support for the Kotlin/JS IR compiler
• Added optional displayActual function to assertThat as an alternative to .toString() for external types
• Moved most String assertions to CharSequence

Added

• Added prop function with KProperty1 argument.
• Added containsExactlyInAnyOrder assertion for Iterable and primitive arrays
• Added initial Coroutines artifact (additional support planned for the future)

Deprecated

• Deprecated prop function with KCallable argument. Use the new overload
  with type-safe KProperty1 argument or another overload with explicit name and lambda.

Fixed

• Primitive array 'contains' methods now work with NaN. ex:

  assertThat(floatArrayOf(Float.Nan)).contains(Float.NaN)

  will pass when it failed before.
• Fixes a bug causing failures to sometimes be dropped in a nested assertion context

Added

• Add multi-value support for Assert<String>.contains() and doesNotContain()
• Add isEqualByComparingTo to compare objects by compareTo instead of equals this is useful for cases like
  BigDecimal where equals would fail because of differing precision.
• Add containsOnly for arrays.

Changed

• Minimum supported kotlin version is 1.3.70
• Updated opentest4j to 1.2.0. This changes the multiple assertion message to include each exception class name.
• Moved containsAll, containsNone, and containsOnly from Collection to Iterable to make
  them a bit more flexible.
• containsAll, containsNone, and containsOnly error messages now include the expected and actual lists.
• Unwrap exceptions thrown by prop(callable: KCallable<*>) to make them more clear.
• Add all exception stacktraces to a MultipleFailuresError with Throwable.addSurpressed on the jvm (used when
  collecting multiple exceptions with assertAll). Unfortunately, if you are using gradle you won't see this due to a
  known gradle issue.
• No longer wrap exceptions in AssertionErrors when using given and transform. Warning: this is techinicaly a
  breaking change as code like:

  try {
      assertThat(foo).given { throw MyException("error") }
  } catch (e: AssertionError) {
      // assume caught
  }

  will no longer be caught. But you shouldn't be writing code like that anyway ;)

Fixed

• Don't let assertAll capture OutOfMemory errors.

Breaking Changes

• Previously deprecated methods (as of 0.18) are now errors.
