Multiple assertions (assertAll) - Kotest

Is any way to check multiple assertions in Kotest in DSL style - without Assertions.assertAll method from JUnit?

Can I write something like

firstValue shouldBe 1
and secondValue shouldBe 2

Instead of

assertAll(
    { fistValue shouldBe 1 },
    { secondValue shouldBe 2 })
Solution

  • I usually do it with assertSoftly. It probably is exactly what you want. From the documentation

    assertSoftly {
  foo shouldBe bar
  foo should contain(baz)
}

    Or using it as a parameter

    assertSoftly(foo) {
    shouldNotEndWith("b")
    length shouldBe 3
}

    However, your syntax works just as fine. You don't really need to assert softly.

    firstValue shouldBe 1
secondValue shouldBe 2

    will execute both assertions. If the first one fails the test crashes early. With assertSoftly, both assertions will be checked.
