playground for junit-based testing frameworks
- spek
- junit5 (data-driven-tests)
- kluent (and json-based assertions)
- kotlintest
- simplespec (damn simple bdd style specs)
$ ./gradlew clean test
- getting started with spek framework
- getting started with junit
- showcases data-driven-testing (dynamic test factory)
-
showcases json-based assertions
items .sortedBy { it.time } .toJson() shouldEqualJson """ [ {"id":"B","time":"2017-06-21T02:10:37.100Z"}, {"id":"A","time":"2017-06-24T05:10:36.100Z"} ] """
- specs
- showcases junit5 (@Test, @TestFactory)
- wraps testcode into a flexible spec
- create proper error messages including steps being executed
- provides no assertion framework, just use the ones you like
Example:
@Test
fun testSumAndSubtract() = simpleSpec {
val calc = "given: a calculator" {
val calc = calculator
calculator shouldBeInstanceOf SimpleCalculator::class
calc
}
val sumResult = "when: calling calculator.sum(3,4)" {
calc.sum(3, 4)
}
"it: should return 7" {
sumResult shouldBe 7
}
val subtractResult = "when: calling calculator.subtract(10,4)" {
calc.subtract(10, 4)
}
"it: should return 6" {
subtractResult shouldBe 6
}
}
