仅当测试在依赖项目中传递时,才能在多项目sbt项目中运行测试

Question

假设一个带有foo项目和bar项目的多项目SBT项目,这样foo项目依赖于bar-project代码等.

如果bar-project中的测试通过,我想在foo-project中进行测试.

怎么样？

Answer 1

您可以在项目之间提供显式依赖关系.例如root - > A - > B.

GitHub上的测试用例.项目定义:

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)
)

从B开始并成功完成:

ezh@mobile ZZZZZZ % sbt-0.13                                          
[info] Set current project to root (in build file:/home/ezh/ZZZZZZ/)
> root/test

[info] TestSpecB:

[success] Total time: 5 s, completed 28.11.2013 16:20:12

从B开始但是失败:

ezh@mobile ZZZZZZ % sbt-0.13
