unit-testing - 根据规范运行单个测试

Question

有没有办法从 Specs 2 Specification 运行特定测试？例如如果我有以下内容:

class FooSpec extends Specification {
  "foo" should {
    "bar" in {
      // ...
    }

    "baz" in {
      // ...
    }
  }
}

我想有一种方法只运行 FooSpec > "foo"> "bar"(在这里使用一些任意的符号)。

Answer 1

您可以使用 sbt 的 ex 参数来运行特定示例:

sbt> test-only *FooSpec* -- ex bar

您还可以混入 org.specs2.mutable.Tags 特征并包含特定标签:

sbt> test-only *FooSpec* -- include investigate

class FooSpec extends Specification with Tags {
  "foo" should {
    tag("investigate")
    "bar" in {
      // ...
    }
    "baz" in {
       // ...
     }
   }
}

您也可以重新运行之前失败的示例，无论它们是什么

sbt> test-only *FooSpec* -- was x

最后，在下一个 2.0 版本中(或使用最新的 1.15-SNAPSHOT)，您将能够创建一个 script.Specification 并使用“自动编号示例组”:

import specification._

/**
 * This kind of specification has a strict separation between the text 
 * and the example code
 */ 
class FooSpec extends script.Specification with Groups { def is = s2"""
  This is a specification for FOO

  First of all, it must do foo
  + with bar
  + with baz

  """ 

  "foo" - new group {
    eg := "bar" must beOk
    eg := "baz" must beOk
  }
}

// execute all the examples in the first group
sbt> test-only *FooSpec* -- include g1

// execute the first example in the first group
sbt> test-only *FooSpec* -- include g1.e1

然而，无法使用可变规范来指定您想要运行示例 "foo"/"bar"。这可能是将来要添加的功能。
