Trait that when mixed into a FixtureAsyncTestSuite passes the config map passed to runTest as a fixture into each test.

Here's an example in which tests just check to make sure "hello" and "world" are defined keys in the config map:

package org.scalatest.examples.fixture.configmapfixture

import org.scalatest._

class ExampleAsyncSpec extends fixture.AsyncFlatSpec with fixture.AsyncConfigMapFixture with Matchers {

  "The config map" should "contain hello" in { configMap =>
    // Use the configMap passed to runTest in the test
    configMap should contain key "hello"
  }

  it should "contain world" in { configMap =>
    configMap should contain key "world"
  }
}

If you run this class without defining "hello" and "world" in the confg map, the tests will fail:

scala> org.scalatest.run(new ExampleSpec)
ExampleSpec:
The config map
- should contain hello *** FAILED ***
  Map() did not contain key "hello" (:20)
- should contain world *** FAILED ***
  Map() did not contain key "world" (:24)

If you do define "hello" and "world" keys in the confg map, the tests will success:

scala> org.scalatest.run(new ExampleSpec, configMap = Map("hello" -> "hi", "world" -> "globe"))
ExampleSpec:
The config map
- should contain hello
- should contain world
