org.scalatest:全局设置(如beforeAllSuites?) [英] org.scalatest: Global setup (like beforeAllSuites?)

问题描述

我有一个使用org.scalatest进行测试的scala应用程序.这些测试需要一些全局设置(和拆卸)，以便管理测试数据库.

I have a scala application with some test using org.scalatest. These test need some global setup (and teardown), in order to manage the test database.

请不要告诉我我的测试不应该访问数据库，而应该使用Java-DAO-Stub-WTF-Overkill-Way™:-).

Please don't tell me my tests should not hit the database and I should do it the Java-DAO-Stub-WTF-Overkill-Way™ :-).

我正在使用SBT运行测试，该测试提供了一种在测试前后执行代码的方式:

I'm running the tests using SBT, which provides a way to execute code before and after test:

    testOptions in Test += Tests.Setup( () => println("Setup") )

    testOptions in Test += Tests.Cleanup( () => println("Cleanup") )

不幸的是，我不能在那里访问有问题的课程.毫不奇怪，将它们导入build.sbt也不起作用.

Unfortunately I cannot access the classes in question there. Unsurprisingly, importing them into build.sbt does not work either.

有什么想法吗?

推荐答案

您可以使用 BeforeAndAfterAll 或 BeforeAndAfter 特质，取决于您的需求.

You can use the BeforeAndAfterAll or BeforeAndAfter traits, depending upon your needs.

BeforeAndAfterAll:

BeforeAndAfterAll:

可以组合到需要先调用方法的套件中的特质 和执行套件后.此特征允许执行代码 在套件的所有测试和嵌套套件之前和/或之后 运行.

Trait that can be mixed into suites that need methods invoked before and after executing the suite. This trait allows code to be executed before and/or after all the tests and nested suites of a suite are run.

因此，在这种情况下，您将定义一个包含所有其他套件/测试的MasterSuite，以扩展此特征.

So in this instance, you would define a MasterSuite which contains all other Suites/Tests, which extends this trait.

之前和之后:

可以组合到需要在之前和之后执行代码的套件中的特质 在运行每个测试之后.此特征有助于在测试中进行测试 实例变量中包含哪些可变夹具对象被替换 或在每个测试或套件之前重新初始化.

Trait that can be mixed into suites that need code executed before and after running each test. This trait facilitates a style of testing in which mutable fixture objects held in instance variables are replaced or reinitialized before each test or suite.
