如何在以sbt运行的junit4中打开断言语句? [英] How to turn on assert statements in junit4 runned with sbt?

问题描述

我在Java项目中将sbt用于开发例程，并在运行测试时使用 junit-interface . 但是默认情况下，它会忽略assert语句(断言以检查基础代码中的某些不变性).例如，该测试通过:

I use sbt for development routines in my java project and junit-interface for running tests. But by default it ignores assert statements(assert for checking some invariant in underlying code). For example this test passes:

@Test
public void test() {
  // this is example; In reality assertion somewhere in code under test
  assert false; // not assertTrue(or whatever) from junit
}

我的build.sbt文件非常简单:

My build.sbt file is fairly simple:

organization := "Kharandziuk"

name := "Some alg project"

version := "1.0-SNAPSHOT"

libraryDependencies ++= Seq(
    "junit" % "junit" % "4.8.1" % "test",
    "com.novocode" % "junit-interface" % "0.10" % "test"
)

autoScalaLibrary := false

testOptions += Tests.Argument(TestFrameworks.JUnit, "-a", "-q", "-v")

fork in run := true

javaOptions in run += "-ea"

如何在测试中启用断言语句?

How I can enable assert statements in tests?

推荐答案

您可以将其设置为单独的任务，例如. test s:

You can set it for separate tasks, eg. tests:

javaOptions in test += "-ea"

或简单地将其设置在任何地方:

or simply set it everywhere:

javaOptions += "-ea"

无论如何，@ MPirious是正确的，因为您通常不希望通过单元测试导致断言失败.单元测试应该沙盒您的代码逻辑

Regardless, @MPirious is right in that you typically don't want to cause assertion failures through unit testing. A unit test is supposed to sandbox your code's logic
