未执行任何测试（Play Framework）

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 v 2.6.11 of Play 和 sbt 0.13.17。过去测试有效，但现在sbt 似乎无法执行。

如果我只是运行sbt test，我会得到No tests were executed.。如果我以sbt --debug 开头sbt，我会得到一个更详细的日志，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：

懒惰的val root =（文件中的项目（“。”）） .enablePlugins(PlayJava,PlayEbean) scalaVersion := "2.11.7" libraryDependencies ++= Seq( javaJdbc, javaWs, javaJpa, 过滤器， 吉斯， // 一堆依赖 ) 依赖覆盖 ++= 设置（ "io.ebean" % "ebean" % "11.14.3" withSources() ) // 由于对 SLF4J 的多个绑定而删除依赖项 excludeDependencies += "org.slf4j" % "slf4j-log4j12" excludeDependencies += "org.log4j" % "log4j" // 不知道为什么但是 activator 阶段在编译时开始报错 // http://stackoverflow.com/questions/22974766/play2-play-stage-command-fails-with-not-found-type-setupcontext 编译中的文档中的来源：= List()

我尝试按照this thread in Github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（通过各种谷歌搜索）：

"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。整个上午我都在各种 Stackoverflow 线程和 github 问题this、this 或 this

如果有人对我如何调试这种情况有一些想法。

Answer 1

在我的情况下，这有效：

打开 sbt 控制台：sbt

运行测试：testOnly * 或 test *

所以添加* 解决了这个问题。

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")

JUnit 测试可能确实在运行，但日志事件处于DEBUG 级别，因此您看不到它们。根据docs-v 选项将它们记录在INFO 级别：

记录“测试运行开始”/“测试开始”/“测试运行完成”事件 在日志级别“信息”而不是“调试”。

在我的机器上设置 -v 选项在 sbt 中给了我以下输出：

[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

如果没有-v 测试选项，则没有输出。
