为什么在使用“sbt it:test"时没有执行 Play/Scala 项目中的集成测试? [英] Why are integration tests in a Play/Scala project not executed when using "sbt it:test"?

问题描述

我有一个 Play Framework 2.3 项目，我想在其中将单元测试和功能测试分开为如下:

I have a Play Framework 2.3 project in which I'd like to separate unit tests and functional tests as follows:

1. 运行 sbt test 应该运行单元测试并排除集成测试
2. 运行 sbt it:test 应该只运行集成测试

1. running sbt test should run unit tests and exclude integration tests
2. running sbt it:test should run integration tests only

Scala 文档建议使用 project/Build.scala，但我想结合使用 build.sbt 和 project/Build.scala，所以我的配置看起来像这样(我也尝试将所有配置放入 Build.scala):

The Scala documentation suggests using project/Build.scala, but I'd like to use combination of build.sbt and project/Build.scala, so my configuration looks like this (I have also tried putting all of configuration into Build.scala):

build.sbt

....

libraryDependencies ++= Seq(
  "com.typesafe.play" %% "play-json" % "2.2.3",
  "org.scalatest" %% "scalatest" % "2.1.5" % "it, test",
  "org.mockito" % "mockito-all" % "1.9.5" % "it, test"
)

def funTestFilter(name: String): Boolean = ((name endsWith "ItTest") || (name endsWith "IntegrationTest"))
def unitTestFilter(name: String): Boolean = ((name endsWith "Test") && !funTestFilter(name))

testOptions in IntegrationTest := Seq(Tests.Filter(funTestFilter))

testOptions in Test := Seq(Tests.Filter(unitTestFilter))

project/Build.scala

import sbt._

object Build extends Build {

  lazy val root =
    Project("root", file("."))
      .configs( IntegrationTest )
      .settings( Defaults.itSettings : _* )

}

在此配置下运行 sbt test 确实排除了我的集成测试(以 IntegrationTest 结尾)但运行 sbt it:test 找不到任何测试.

Under this configuration running sbt test does exclude my integration test (which ends with IntegrationTest) but running sbt it:test finds no tests.

文章建议将文件放在特定路径中，但我不知道 Play 项目的等效路径是什么.

The article suggests putting files in a specific path, but I don't know what the equivalent path is for the Play project.

使用标准源层次结构:

src/it/scala for Scala sources
src/it/java for Java sources
src/it/resources for resources that should go on the integration test classpath

推荐答案

第一部分 - 关于在 build.sbt 中设置集成测试 - 在另一个问题 sbt 0.13.x 中 IntegrationTest 配置的最小设置是什么? -- 归结为 build.sbt 中的以下条目代码>:

The first part - about setting up integration tests in build.sbt - is described in another question What would be the minimal setup of IntegrationTest configuration in sbt 0.13.x? -- it boils down to the following entries in build.sbt:

Defaults.itSettings

lazy val root = project.in(file(".")).configs(IntegrationTest)

由于一个 Play 项目的定义如下:

Since a Play project is defined as follows:

lazy val root = (project in file(".")).enablePlugins(PlayScala)

你应该添加 configs 就完成了.

you should add configs and you're done.

lazy val root = project in file(".") enablePlugins(PlayScala) configs(IntegrationTest) 

执行 reload 或重新启动 sbt/activator 会话并执行 it:test.

Do reload or restart the sbt/activator session and execute it:test.

[it-play] $ it:test
[info] Updating {file:/Users/jacek/sandbox/it-play/}root...
[info] Resolving jline#jline;2.11 ...
[info] Done updating.
[success] Total time: 1 s, completed Sep 13, 2014 7:12:27 PM

关于集成测试在 Play 项目中的位置，简短的回答是在 shell 中执行 show it:sourceDirectory，即 src/it 与scala、java 和 resources 目录下包含各自的源代码.

As to the place where the integration tests should go in a Play project, the short answer is do show it:sourceDirectory in the shell, i.e. src/it with scala, java and resources directories beneath to contain respective sources.

在 it 配置中添加测试框架库，即在 build.sbt 中应该有类似的东西 - 注意 it 配置:

Add test framework library in it configuration, i.e. in build.sbt there should be something similar to - note the it configuration:

"org.specs2" %% "specs2" % "2.4.2" % "it"

reload sbt 会话或重新启动它，并且 it:test 应该适用于 src/it/scala.

Do reload the sbt session or restart it, and it:test should work with Specs2 tests for all tests under src/it/scala.

要缩小应执行的测试范围，请添加您的过滤器 - 确保它位于 Defaults.itSettings 行之后，因为顺序很重要，并且可以覆盖另一个:

To narrow what tests should be executed, add your filter - make sure it's after the line with Defaults.itSettings as the order does matter and one can override the other:

val funTestFilter: String => Boolean = { name =>
  (name endsWith "ItTest") || (name endsWith "IntegrationTest")
}

testOptions in IntegrationTest += Tests.Filter(funTestFilter)

执行 reload 或重启 sbt 并执行 it:test.它应该工作.执行 show it:testOptions 以确保您的设置正确加载:

Do reload or restart sbt and execute it:test. It should work. Do show it:testOptions to ensure your setup's loaded properly:

[it-play] $ show it:testOptions
[info] List(Filter(<function1>))

对我有用的整个 build.sbt 如下 - 它是由 activator new it-play play-scala 创建的:

The entire build.sbt that worked for me is as follows - it's created by activator new it-play play-scala:

name := """it-play"""

version := "1.0-SNAPSHOT"

lazy val root = project in file(".") enablePlugins(PlayScala) configs(IntegrationTest)

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws,
  "org.specs2" %% "specs2" % "2.4.2" % "it"
)

Defaults.itSettings

val funTestFilter: String => Boolean = { name =>
  (name endsWith "ItTest") || (name endsWith "IntegrationTest")
}

testOptions in IntegrationTest += Tests.Filter(funTestFilter)
