通过创建以下文件，我能够使用命令sbt test运行所有测试。

• build.sbt个

libraryDependencies ++= Seq(
  "org.scalactic"     %% "scalactic"         % "3.2.16",
  "org.scalatest"     %% "scalatest"         % "3.2.16"   % Test,
  "org.scalatestplus" %% "scalacheck-1-17"   % "3.2.16.0" % Test,
  "dev.zio"           %% "zio"               % zioVersion,
  "dev.zio"           %% "zio-test"          % zioVersion % Test,
  "dev.zio"           %% "zio-test-sbt"      % zioVersion % Test,
  "dev.zio"           %% "zio-test-magnolia" % zioVersion % Test,
  "dev.zio"           %% "zio-test-junit"    % zioVersion % Test
),
testFrameworks += new TestFramework("zio.test.sbt.ZTestFramework")

object ZioHelloWorld {
  def sayHello: ZIO[Any, IOException, Unit] =
    Console.printLine("Hello, World!")

• ZioHelloWorldSpec.scala个

import ZioHelloWorld._

object ZioHelloWorldSpec extends ZIOSpecDefault {
  def spec =
    suite("ZioHelloWorldSpec")(test("sayHello correctly displays output zio test") {
      for {

      } yield assertTrue(output == Vector("Hello, World!\n"))

• ZioJunitHelloWorldSpec.scala个

你有两种Integrating ZIO Test with JUnit的方法。一个是下面添加的示例，另一个是在类定义上方添加注解@RunWith(classOf[ZTestJUnitRunner])，混合ZIOSpecDefault而不是JUnitRunnableSpec，并添加库"com.github.sbt" % "junit-interface" % "0.13.3" % Test

import ZioHelloWorld._
import zio.test._
import zio.test.junit.JUnitRunnableSpec

object ZioJunitHelloWorldSpec extends JUnitRunnableSpec {
  def spec =
    suite("ZioJunitHelloWorldSpec")(test("sayHello correctly displays output using junit") {
      for {
        _ <- sayHello
        output <- TestConsole.output
      } yield assertTrue(output == Vector("Hello, World!\n"))
    })
}

import org.scalatestplus.scalacheck.ScalaCheckPropertyChecks

class HelloScalaTest extends AnyFunSuite with Matchers with ScalaCheckPropertyChecks {

  test("1 should be 1") {
    1 should be(1)
  }

  test("(a + b) should be (b + a)") {
    forAll { (a: Int, b: Int) =>
      (a + b) should be(b + a)
    }
  }

执行sbt test后，我得到以下输出

+ ZioHelloWorldSpec
Hello, World!
Hello, World!
  + sayHello correctly displays output zio test
+ ZioJunitHelloWorldSpec
  + sayHello correctly displays output using junit
[info] HelloScalaTest:
[info] - 1 should be 1
[info] - (a + b) should be (b + a)
4 tests passed. 0 tests failed. 0 tests ignored.
