Question

我在Play Framework应用程序中运行单元测试时遇到问题。我目前正在使用Play v 2.6.11和sbt 0.13.17。测试过去一直有效，但似乎现在sbt无法执行它们。

如果我只是运行sbt test，我会No tests were executed.。如果我使用sbt启动sbt --debug，我会收到更详细的日志，其中包含以下内容：

[debug] [naha] . [debug] [naha] All member reference dependencies will be considered within this context. [debug] [naha] New invalidations: [debug] [naha] Set() [debug] [naha] Initial set of included nodes: Set() [debug] [naha] Previously invalidated, but (transitively) depend on new invalidations: [debug] [naha] Set() [debug] [naha] All newly invalidated sources after taking into account (previously) recompiled sources:Set() [debug] Copy resource mappings: [debug] [debug] Framework implementation 'org.scalacheck.ScalaCheckFramework' not present.

这是我的build.sbt文件：

lazy val root = (project in file("."))
  .enablePlugins(PlayJava,PlayEbean)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  javaJdbc,
  javaWs,
  javaJpa,
  filters,
  guice,
  // Bunch of Dependencies
)

dependencyOverrides ++= Set(
  "io.ebean" % "ebean" % "11.14.3" withSources()
)

// Remove dependencies because of Multiple Bindings to SLF4J
excludeDependencies += "org.slf4j" % "slf4j-log4j12"
excludeDependencies += "org.log4j" % "log4j"

// Don't know why But activator stage started to complain while Compiling
// http://stackoverflow.com/questions/22974766/play2-play-stage-command-fails-with-not-found-type-setupcontext
sources in doc in Compile := List()

我已根据this thread in Github

尝试添加crossPaths := false

自从我在Missing Implementations上看到该消息后，我已将此消息添加到我的build.sbt（通过各种Google搜索）：

"org.scalatest" %% "scalatest" % "3.0.5" % Test, "com.novocode" % "junit-interface" % "0.11" % Test, "org.exparity" % "hamcrest-date" % "2.0.0" % Test

但没有运气。我整个上午都遇到过各种Stackoverflow线程和github问题this，this或this

如果有人对如何调试这种情况有一些想法。

Answer 1

就我而言，这有效：

打开sbt控制台：sbt

运行测试：testOnly *或test *

因此添加*解决了问题。

Answer 2

如果您正在运行JUnit测试，请将以下内容添加到build.sbt：

libraryDependencies += "com.novocode" % "junit-interface" % "0.11" % "test"
testOptions += Tests.Argument(TestFrameworks.JUnit, "-v")

可能是JUnit测试确实正在运行，但日志事件处于DEBUG级别，因此您无法看到它们。根据{{3}} -v选项，将其记录在INFO级别：

Log＆＃34;测试运行开始＆＃34; /＆＃34;测试开始＆＃34; /＆＃34;测试运行结束＆＃34;事件在日志级别＆＃34;信息＆＃34;而不是＆＃34; debug＆＃34;。

在我的机器设置-v选项中，我在sbt：

中给出了以下输出

[info] Test run started
[info] Test com.gu.identitycommon.clickthrough.TokenServiceTest.shouldFlagInvalidPasswordResetTokens started
[info] Test com.gu.identitycommon.clickthrough.TokenServiceTest.shouldEndcodeAndDecodeActivationToken started
[info] Test com.gu.identitycommon.clickthrough.TokenServiceTest.shouldDecoedToNullUserGroupIfNoneProvidedInActivationToken started
[info] Test com.gu.identitycommon.clickthrough.TokenServiceTest.shouldRecognizeValidPasswordResetTokens started
[info] Test run finished: 0 failed, 0 ignored, 4 total, 0.276s
[info] Test run started

虽然没有-v测试选项，但没有输出。

没有执行任何测试（Play Framework）
