.sbt重新定义测试任务

Question

For my specific reason, I'd like to override test task to run not all tests, but to behave like test-only TopTestSuiteName param1 param2 . Is it possible?

I tried to go through documentation on tasks and examples, but still far from understanding what is possible and what's not.

Or maybe I could create custom task and somehow use existing test-only functionality? I feel it is reasonable but completely cannot understand - where do I start.

Answer 1

I would suggest you leave test alone and add a custom thing instead.

How about an alias? You could just add this to your .sbt definition:

addCommandAlias("myTest", "testOnly TopTestSuiteName -- param1 param2")

But if you actually need myTest to be a task (for example if you want another task to depend on it), then here's code (in .sbt format for sbt 0.13) for reusing testOnly functionality in a custom task:

val myTest = taskKey[Unit]("call testOnly with some special args")

myTest in Test :=
  (testOnly in Test).toTask(" TopTestSuiteName -- param1 param2").value
