trait AsyncTimeLimitedTests extends AsyncTestSuiteMixin with TimeLimits
Trait that when mixed into an asynchronous suite class establishes a time limit for its tests.
This trait overrides withFixture
, wrapping a super.withFixture(test)
call
in a failAfter
invocation, specifying a timeout obtained by invoking timeLimit
:
failAfter(timeLimit) {
super.withFixture(test)
}
Note that the failAfter
method executes the body of the by-name passed to it using the same
thread that invoked failAfter
. This means that the calling of withFixture
method
will be run using the same thread, but the test body may be run using a different thread, depending on the
executionContext
set at the AsyncTestSuite
level.
The timeLimit
field is abstract in this trait. Thus you must specify a time limit when you use it.
For example, the following code specifies that each test must complete within 200 milliseconds:
import org.scalatest.AsyncFunSpec import org.scalatest.concurrent.AsyncTimeLimitedTests import org.scalatest.time.SpanSugar._
class ExampleSpec extends AsyncFunSpec with AsyncTimeLimitedTests {
// Note: You may need to either write 200.millis or (200 millis), or // place a semicolon or blank line after plain old 200 millis, to // avoid the semicolon inference problems of postfix operator notation. val timeLimit = 200 millis
describe("An asynchronous time-limited test") { it("should succeed if it completes within the time limit") { Thread.sleep(100) succeed } it("should fail if it is taking too darn long") { Thread.sleep(300) succeed } } }
If you run the above ExampleSpec
, the second test will fail with the error message:
The test did not complete within the specified 200 millisecond time limit.
Different from TimeLimitedTests
, AsyncTimeLimitedTests
does not
support Interruptor
for now.
