Выполнять тесты в проектах нескольких проектов sbt, только если тесты проходят в зависимых проектах

Ответ 1

Вы можете предоставлять явные зависимости между проектами. Например, root → A → B

Тест-сценарий на GitHub. Определение проекта:

val commonSettings = Seq(libraryDependencies += "org.scalatest" %% "scalatest" % "1.9.1")

lazy val a: Project = (project in file("a")) settings(commonSettings: _*) settings(
    name := "a",
    test in Test <<= test in Test dependsOn (test in Test in b)
)

lazy val b: Project = (project in file("b")) settings(commonSettings: _*) settings(
    name := "b"
)

lazy val root: Project = (project in file(".")) settings(commonSettings: _*) settings(
    name := "root",
    test in Test <<= test in Test dependsOn (test in Test in a)
)

Начиная с B и успешно завершая их:

[email protected] ZZZZZZ % sbt-0.13

Начиная с B, но сбой:

как уже отмечалось, это, вероятно, зло, однако это, вероятно, должно работать:

import sbt._
    import sbt.Keys._
    object Build extends Build {
      lazy val projectA = project
      lazy val myTest = taskKey[Seq[Option[Tests.Output]]]("my test")
      lazy val root: Project = project in file(".") settings (myTest <<= myTestTask) dependsOn projectA

      def myTestTask = Def.task {
        val state: State = Keys.state.value
        val log: Logger = streams.value.log
        val extracted = Project.extract(state)
        import extracted._
        def noTestsMessage(scoped: ScopedKey[_])(implicit display: Show[ScopedKey[_]]): String =
          "No tests to run for " + display(scoped)
        def f(ref: ProjectReference) = for {
          state Pair Value(r) <- Project.runTask(executeTests in(ref, Test), state)
          _ = Tests.showResults(log, r, noTestsMessage(test in ref))
        } yield r
        val depsTests = currentProject.dependencies.map(_.project).map(f)
        val passed = depsTests.forall(_.forall(_.overall == TestResult.Passed))
        if (passed) depsTests :+ f(ThisProject) else depsTests
      }
    }
