I've noticed that SBT is running my specs2 tests in parallel. This seems good, except one of my tests involves reading and writing from a file and hence fails unpredictably, e.g. see below.
Are there any better options than
- setting all tests to run in serial,
- using separate file names and tear-downs for each test?
class WriteAndReadSpec extends Specification{
val file = new File("testFiles/tmp.txt")
"WriteAndRead" should {
"work once" in {
new FileWriter(file, false).append("Foo").close
Source.fromFile(file).getLines().toList(0) must_== "Foo"
}
"work twice" in {
new FileWriter(file, false).append("Bar").close
Source.fromFile(file).getLines().toList(0) must_== "Bar"
}
}
trait TearDown extends After {
def after = if(file.exists) file.delete
}
}
