Fail Fast

Kotest can eagerly fail a list of tests if one of those tests fails. This is called fail fast.

Fail fast can take affect at the spec level, or at a parent test level.

In the following example, we enable failfast for a parent test, and the first failure inside that context, will cause the rest to be skipped.

class FailFastTests() : FunSpec() {
init {
context("context with fail fast enabled").config(failfast = true) {
test("a") {} // pass
test("b") { error("boom") } // fail
test("c") {} // skipped
context("d") { // skipped
test("e") {} // skipped
}
}
}
}

This can be enabled for all scopes in a Spec by setting failfast at the spec level.

class FailFastTests() : FunSpec() {
init {

failfast = true

context("context with fail fast enabled at the spec level") {
test("a") {} // pass
test("b") { error("boom") } // fail
test("c") {} // skipped
context("d") { // skipped
test("e") {} // skipped
}
}
}
}
