OneInstancePerTest

The total number of tests that are expected to run when this Suite's run method is invoked.

A List of this Suite object's nested Suites. If this Suite contains no nested Suites, this method returns an empty List.

Runs this suite of tests.

Runs zero to many of this suite's nested suites.

Runs a test.

A Map whose keys are String tag names with which tests in this Suite are marked, and whose values are the Set of test names marked with each tag. If this Suite contains no tags, this method returns an empty Map.

Subclasses may implement this method to define and/or discover tags in a custom manner, but overriding method implementations should never return an empty Set as a value. If a tag has no tests, its name should not appear as a key in the returned Map.

An Set of test names. If this Suite contains no tests, this method returns an empty Set.

Although subclass and subtrait implementations of this method may return a Set whose iterator produces String test names in a well-defined order, the contract of this method does not required a defined order. Subclasses are free to implement this method and return test names in either a defined or undefined order.

Runs the passed test function with a fixture established by this method.

This method should set up the fixture needed by the tests of the current suite, invoke the test function, and if needed, perform any clean up needed after the test completes. Because the NoArgTest function passed to this method takes no parameters, preparing the fixture will require side effects, such as reassigning instance vars in this Suite or initializing a globally accessible external database. If you want to avoid reassigning instance vars you can use fixture.Suite.

Construct a new instance of this Suite.

This trait's implementation of runTests invokes this method to create a new instance of this Suite for each test. This trait's implementation of this method uses reflection to call this.getClass.newInstance. This approach will succeed only if this Suite's class has a public, no-arg constructor. In most cases this is likely to be true, because to be instantiated by ScalaTest's Runner a Suite needs a public, no-arg constructor. However, this will not be true of any Suite defined as an inner class of another class or trait, because every constructor of an inner class type takes a reference to the enclosing instance. In such cases, and in cases where a Suite class is explicitly defined without a public, no-arg constructor, you will need to override this method to construct a new instance of the Suite in some other way.

Here's an example of how you could override newInstance to construct a new instance of an inner class:

import org.scalatest.Suite

class Outer {
  class InnerSuite extends Suite with OneInstancePerTest {
    def testOne() {}
    def testTwo() {}
    override def newInstance = new InnerSuite
  }
}

Run this Suite's tests each in their own instance of this Suite's class.

If the passed testName is None, this trait's implementation of this method will for each test name returned by testNames, invoke newInstance to get a new instance of this Suite, and call run on it, passing in the test name wrapped in a Some. If the passed testName is defined, this trait's implementation of this method will simply forward all passed parameters to super.run. If the invocation of either newInstance on this Suite or run on a newly created instance of this Suite completes abruptly with an exception, then this runTests method will complete abruptly with the same exception.
