scalatest

As per the title, I'm wondering if it's possible to provide "assumptions" to Scalatest when defining a particular test case. Assumptions in this context would be preconditions for a test, such that if the assumption evaluated to false, the test would be skipped rather than executed (and handled accordingly by the runners). In this particular case, I'm thinking about dependencies between tests - so there might be a basic test that validates whether a method returns anything at all , followed by later tests that drill into the specifics of the response. If the former test fails, I'd rather have

I created a scala project using SBT and wrote some unit test cases using scalatest. But somehow sbt test can't find the org.scalatest package. Here my project definition files: Sources are in src/main/scala respective src/test/scala build.sbt : name := "MyProject" version := "0.1" scalaVersion := "2.9.2" project/plugins.sbt : addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0") project/build.sbt : libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test" I'm using SBT 0.11.3. Compiling the program using sbt compile on the console works fine. Furthermore I found

Problem: I cannot setup Run Configurations to run scalatest for the Scalatests in my project. Steps to reproduce: Right click on Scala Suite and click on Run as -> Run configurations.. On the left, I see a configuration template for ScalaTest. I click on New and fill the Name but it cannot find the suite-class. Note: It is mentioned here that I should see Run as -> ScalaTest - Suite but I do not see that option. I tried using context menu in the editor, and in the package explorer Steps taken: Using: Scala IDE for Eclipse version: 2.1.0.m3-2_09 Using SBT, assemble project, run eclipse command

Is there any way to test a nested function (ideally with ScalaTest)? For example, is there a way to test g() in the below code: def f() = { def g() = "a string!" g() + "– says g" } g is not visible outside of f , so I daresay no, at least not without reflection. I think testing g would break the concept of unit testing, anyway, because you should never test implementation details but only public API behaviour. Tracking an error to a mistake in g is part of the debugging process if tests for f fail. If testing g is important for you, define g as (protected) method outside of f . That might

I'am toying with Specs2 and ScalaTest for BDD in Scala. I've written expectations in Specs2 when I am asserting that a given exception should not be thrown. "do something" in { { .... } must not(throwA[MyException]) } I was hoping to be able to write the equivalent in ScalaTest like: "do something" in { evaluating { .... } should not produce[MyException] } But this does not compile and I could not find way of doing it. Is that even possible? Many thanks in advance. This is not possible directly in the latest version of ScalaTest because the method should of EvaluatingApplicationShouldWrapper
