我们在ScalaTest中使用Spec trait进行测试.当我们运行整个套件时,它并不总是以相同的顺序运行.谷歌的大多数答案建议定义一个套件并指定所有测试名称.但这需要我们在每次添加新测试时添加测试名称.
是否可以使用DiscoverySuite本身并定义测试执行顺序？就像按字母顺序运行测试一样.我考虑扩展DiscoverySuite,但DiscoverySuite似乎是私有的scalatest.

通过命令我的意思是,如果有测试A,B,C.
class A extends Spec {..}
class B extends Spec {..}
class C extends Spec {..}
然后我希望测试按顺序(A,B,C)运行.但现在发生的是,它每次都以不同的顺序运行.
我有一个混合的Java/Scala项目,包括JUnit和ScalaTest测试.使用scalatest插件,Gradle运行ScalaTest测试src/test/scala,但忽略了JUnit测试src/test/java.没有插件,Gradle运行JUnit测试但忽略Scala.我错过了什么伎俩？

以下是我的Gradle依赖项：

testImplementation 'org.scalatic:scalatic_2.13:3.0.8'
testImplementation 'org.scalatest:scalatest_2.13:3.0.8'
}
当我将依存关系更改为Scala 2.12.x时，测试将在IntelliJ中正确执行而没有错误。这里发生了什么？
我从sbt运行我的scalatest,输出混合起来 - scalatest打印所有测试运行,并对它们发表评论,并在中间某处打印统计信息:

argLine:选项以指定要传递给分叉进程的其他JVM选项environmentVariables:要传递给分叉进程的其他环境变量systemProperties:要传递给分叉进程的其他系统属性但这不是多余的吗？例如,如果我想传递environment=development,我需要在以下内容中指定以下内容pom.xml:
<plugin>
<groupId>org.scalatest</groupId>
<artifactId>scalatest-maven-plugin</artifactId>
<configuration>
<argLine>-Denvironment=${env}</argLine>
</configuration>
</plugin>
然后跑mvn test -Denv=development.是否有更简单的方法将命令行参数直接传递给ScalaTest？
scalatest和spock有何不同？每个的附加价值是多少？哪个更适合行为驱动开发(BDD)？请问您能就此事分享一些想法吗？
我想开始BDD,我想在两者之间选择一个,因此我想做出一个有根据的决定.因此,我首先得到最多的信息,特别是考虑到我是一名java程序员,scala似乎有一个重要的学习曲线.
任何建议或想法或经验回报都是受欢迎的.
非常感谢
我正在使用ScalaTest运行一些测试,这些测试依赖于连接来测试服务器是否存在.我目前创建了自己的Spec,类似于:
abstract class ServerDependingSpec extends FlatSpec with Matchers {
def serverIsAvailable: Boolean = {
// Check if the server is available
}
}
当此方法返回时,是否可以忽略(但不会失败)测试false？
目前我是以"hackish"方式做到的:
"Something" should "do something" in {
if(serverIsAvailable) {
// my test code
}
}
但我想要类似的东西
whenServerAvailable "Something" should "do something" in {
// test code
}
要么
"Something" should "do something" whenServerAvailable {
// test code
}
我想我应该定义我的自定义标签,但我只能参考in或者的源代码,ignore我不明白我应该如何插入我的自定义实现.
我该怎么做到这一点？
我有这个代码100%来自sbt,执行sbt test但在Intellij Idea中抛出一个编译错误.
import org.scalatest.{BeforeAndAfter, FunSuite, GivenWhenThen}
class SimpleTest extends FunSuite with GivenWhenThen with BeforeAndAfter {
test("Simple Test") {
Given("Why this error?")
assert("ok" === "ok")
}
}
错误是:
Error:(5, 10) could not find implicit value for parameter pos: org.scalactic.source.Position
Given("Why this error?")
Error:(5, 10) not enough arguments for method Given: (implicit pos: org.scalactic.source.Position)Unit.

Given("Why this error?")
Error:(6, 11) could not find implicit value for parameter prettifier: org.scalactic.Prettifier

import org.apache.spark.sql.SparkSession
import org.scalatest.{BeforeAndAfterAll, FlatSpec}
class ClassNameSpec extends FlatSpec with BeforeAndAfterAll {
var spark: SparkSession = _
var className: ClassName = _
override def beforeAll(): Unit = {
spark = SparkSession.builder().master("local").appName("class-name-test").getOrCreate()
className = new ClassName(spark)
}
it should "return data" in {
import spark.implicits._
val result = className.getData(input)
assert(result.count() == 3)
}
override def afterAll(): Unit = {
spark.stop()
}
}
当我尝试编译测试套件时,它会给我以下错误:
stable identifier required, but ClassNameSpec.this.spark.implicits found.
[error] import spark.implicits._
