  _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.clock.nanoTime
  import Assertion.isGreaterThan
  
  object MyTest extends DefaultRunnableSpec {
    def spec = suite("clock")(
      testM("time is non-zero") {
        assertM(nanoTime)(isGreaterThan(0))
      }
    )

  The Annotations trait provides access to an annotation map that tests can add arbitrary annotations to.

  The Annotations trait provides access to an annotation map that tests can add arbitrary annotations to. Each annotation consists of a string identifier, an initial value, and a function for combining two values. Annotations form monoids and you can think of Annotations as a more structured logging service or as a super polymorphic version of the writer monad effect.
