Kotest v2.0.0 Release Notes

Release Date: 2017-03-26 // about 7 years ago

  • 👕 Closed Issues

    ➕ Added

    • ✅ You can write tests alternatively into a lambda parameter in the class constructor, eg:
    class StringSpecExample : StringSpec({
  "strings.size should return size of string" {
    "hello".length shouldBe 5
    "hello" should haveLength(5)
  }
})
    • ➕ Added forNone for table tests, eg
    val table = table(
    headers("a", "b"),
    row(0L, 2L),
    row(2L, 2L),
    row(4L, 5L),
    row(4L, 6L)
)

forNone(table) { a, b ->
  3 shouldBe between(a, b)
}

    • 👀 Interceptors have been added. Interceptors allow code to be executed before and after a test. See the main readme for more info.

    • 👀 Simplified ability to add custom matchers. Simple implement Matcher<T> interface. See readme for more information.

    • ➕ Added shouldNot to invert matchers. Eg, "hello" shouldNot include("hallo")

    • 🗄 Deprecated matchers which do not implement Matcher. Eg, should have substring(x) has been deprecated in favour of "hello" should include("l"). This is because instances of Matcher can be combined with or and and and can be negated with shouldNot.

    • ➕ Added between matcher for int and long, eg

    3 shouldBe between(2, 5)

    • Added singleElement matcher for collections, eg

    x shouldBe singleElement(y)

    • ➕ Added sorted matcher for collections, eg

    listOf(1,2,3) shouldBe sorted<Int>()

    • Now supports comparsion of arrays #116

    • Added Gen.oneOf to create a generator that returns one of the values for the given Enum class.

    Changed

    • Tags are objects derived from Tag class now.
    • Tags can now be included and/or exluded. It is no longer the case that all untagged tests are always executed.
    • Fixed bugs with parenthesis breaking layout in Intellij #112

    Removed

    • FlatSpec was removed because it has an irregular syntax with config and is essentially the same as StringSpec, but more complicated.
    • Deprecated method overloads with duration: Long, unit: TimeUnit
    • expecting for testing exceptions (use shouldThrow now)
