    _ZIO Test_ is a featherweight testing library for effectful programs.

    _ZIO Test_ is a featherweight testing library for effectful programs.

    The library imagines every spec as an ordinary immutable value, providing tremendous potential for composition. Thanks to tight integration with ZIO, specs can use resources (including those requiring disposal), have well- defined linear and parallel semantics, and can benefit from a host of ZIO combinators.

    import zio.test._
import zio.test.environment.Live
import zio.Clock.nanoTime
import Assertion.isGreaterThan

object MyTest extends DefaultRunnableSpec {
  def spec = suite("clock")(
    test("time is non-zero") {
      assertM(Live.live(nanoTime))(isGreaterThan(0))
    }
  )
}

  • package environment

    The environment package contains testable versions of all the standard ZIO environment types through the TestClock, TestConsole, TestSystem, and TestRandom modules.

    The environment package contains testable versions of all the standard ZIO environment types through the TestClock, TestConsole, TestSystem, and TestRandom modules. See the documentation on the individual modules for more detail about using each of them.

    If you are using ZIO Test and extending RunnableSpec a TestEnvironment containing all of them will be automatically provided to each of your tests. Otherwise, the easiest way to use the test implementations in ZIO Test is by providing the TestEnvironment to your program.

    import zio.test.environment._

myProgram.provideLayer(testEnvironment)

    Then all environmental effects, such as printing to the console or generating random numbers, will be implemented by the TestEnvironment and will be fully testable. When you do need to access the "live" environment, for example to print debugging information to the console, just use the live combinator along with the effect as your normally would.

    If you are only interested in one of the test implementations for your application, you can also access them a la carte through the make method on each module. Each test module requires some data on initialization. Default data is included for each as DefaultData.

    import zio.test.environment._

myProgram.provideM(TestConsole.make(TestConsole.DefaultData))

    Finally, you can create a Test object that implements the test interface directly using the makeTest method. This can be useful when you want to access some testing functionality without using the environment type.

    import zio.test.environment._

for {
  testRandom <- TestRandom.makeTest(TestRandom.DefaultData)
  n          <- testRandom.nextInt
} yield n

    This can also be useful when you are creating a more complex environment to provide the implementation for test services that you mix in.

Type Members

  1. final case class Data(duration: zio.Duration, sleeps: List[(zio.Duration, Promise[Nothing, Unit])], timeZone: ZoneId) extends Product with Serializable

    Data represents the state of the TestClock, including the clock time and time zone.

  2. final case class Sleep(duration: zio.Duration, promise: Promise[Nothing, Unit], fiberId: Id) extends Product with Serializable

    Sleep represents the state of a scheduled effect, including the time the effect is scheduled to run, a promise that can be completed to resume execution of the effect, and the fiber executing the effect.

  3. sealed abstract class SuspendedWarningData extends AnyRef
  4. final case class Test(clockState: Ref[Data], live: Live, annotations: Annotations, warningState: Synchronized[WarningData], suspendedWarningState: Synchronized[SuspendedWarningData]) extends Clock with TestClock with Product with Serializable
  5. sealed abstract class WarningData extends AnyRef

    WarningData describes the state of the warning message that is displayed if a test is using time by is not advancing the TestClock.

    WarningData describes the state of the warning message that is displayed if a test is using time by is not advancing the TestClock. The possible states are Start if a test has not used time, Pending if a test has used time but has not adjusted the TestClock, and Done if a test has adjusted the TestClock or the warning message has already been displayed.
