BeforeAndAfterAllConfigMap

trait BeforeAndAfterAllConfigMap extends SuiteMixin

Trait that can be mixed into suites that need methods that make use of the config map invoked before and/or after executing the suite.

This trait allows code to be executed before and/or after all the tests and nested suites of a suite are run. This trait overrides run and calls the beforeAll(ConfigMap) method, then calls super.run. After the super.run invocation completes, whether it returns normally or completes abruptly with an exception, this trait's run method will invoke afterAll(ConfigMap).

Note that this trait differs from BeforeAndAfterAll in that it gives the beforeAll and afterAll code access to the config map. If you don't need the config map, use BeforeAndAfterAll instead.

Trait BeforeAndAfterAllConfigMap defines beforeAll and afterAll methods that take a configMap. This trait's implemention of each method does nothing.

For example, the following ExampleSpec mixes in BeforeAndAfterAllConfigMap and in beforeAll, creates and writes to a temp file, taking the name of the temp file from the configMap. This same configMap is then passed to the run methods of the nested suites, OneSpec, TwoSpec, RedSpec, and BlueSpec, so those suites can access the filename and, therefore, the file's contents. After all of the nested suites have executed, afterAll is invoked, which again grabs the file name from the configMap and deletes the file. Each of these five test classes extend trait TempFileExistsSpec, which defines a test that ensures the temp file exists. (Note: if you're unfamiliar with the withFixture(OneArgTest) approach to shared fixtures, check out the documentation for trait fixture.FlatSpec.)

package org.scalatest.examples.beforeandafterallconfigmap

import org.scalatest._ import java.io._
trait TempFileExistsSpec extends fixture.FlatSpec {
type FixtureParam = File override def withFixture(test: OneArgTest) = { val fileName = test.configMap.getRequired[String]("tempFileName") val file = new File(fileName) withFixture(test.toNoArgTest(file)) // loan the fixture to the test }
"The temp file" should ("exist in " + suiteName) in { file => assert(file.exists) } }
class OneSpec extends TempFileExistsSpec class TwoSpec extends TempFileExistsSpec class RedSpec extends TempFileExistsSpec class BlueSpec extends TempFileExistsSpec
class ExampleSpec extends Suites( new OneSpec, new TwoSpec, new RedSpec, new BlueSpec ) with TempFileExistsSpec with BeforeAndAfterAllConfigMap {
private val tempFileName = "tempFileName"
// Set up the temp file needed by the test, taking // a file name from the config map override def beforeAll(cm: ConfigMap) { assume( cm.isDefinedAt(tempFileName), "must place a temp file name in the config map under the key: " + tempFileName ) val fileName = cm.getRequired[String](tempFileName) val writer = new FileWriter(fileName) try writer.write("Hello, suite of tests!") finally writer.close() }
// Delete the temp file override def afterAll(cm: ConfigMap) { val fileName = cm.getRequired[String]("tempFileName") val file = new File(fileName) file.delete() } }

Running the above class in the interpreter will give an error if you don't supply a mapping for "tempFileName" in the config map:

scala> org.scalatest.run(new ExampleSpec)
ExampleSpec:
Exception encountered when invoking run on a suite. *** ABORTED ***
  Exception encountered when invoking run on a suite. (:30)
*** RUN ABORTED ***
  An exception or error caused a run to abort: must place a temp file name in the config map under the key: tempFileName (:30)

If you do supply a mapping for "tempFileName" in the config map, you'll see that the temp file is available to all the tests:

scala> (new ExampleSpec).execute(configMap = ConfigMap("tempFileName" -> "tmp.txt"))
ExampleSpec:
OneSpec:
The temp file
- should exist in OneSpec
TwoSpec:
The temp file
- should exist in TwoSpec
RedSpec:
The temp file
- should exist in RedSpec
BlueSpec:
The temp file
- should exist in BlueSpec
The temp file
- should exist in ExampleSpec

Note: As of 2.0.M5, this trait uses the newly added Status result of Suite's "run" methods to ensure that the code in afterAll is executed after all the tests and nested suites are executed even if a Distributor is passed.

Note that it is not guaranteed that afterAll is invoked from the same thread as beforeAll, so if there's any shared state between beforeAll and afterAll you'll need to make sure they are synchronized correctly.

    A string ID for this Suite that is intended to be unique among all suites reported during a run.

    The suite ID is intended to be unique, because ScalaTest does not enforce that it is unique. If it is not unique, then you may not be able to uniquely identify a particular test of a particular suite. This ability is used, for example, to dynamically tag tests as having failed in the previous run when rerunning only failed tests.

    Flag to indicate whether to invoke beforeAll and afterAll even when there are no tests expected.

    The default value is false, which means beforeAll and afterAll will not be invoked if there are no tests expected. Whether tests are expected is determined by invoking expectedTestCount passing in the passed filter. Because this count does not include tests excluded based on tags, such as ignored tests, this prevents any side effects in beforeAll or afterAll if no tests will ultimately be executed anyway. If you always want to see the side effects even if no tests are expected, override this val and set it to true.

  18. def run(testName: Option[String], args: Args): Status

    Execute a suite surrounded by calls to beforeAll and afterAll.

    Execute a suite surrounded by calls to beforeAll and afterAll.

    This trait's implementation of this method ("this method") invokes beforeAll(ConfigMap) before executing any tests or nested suites and afterAll(ConfigMap) after executing all tests and nested suites. It runs the suite by invoking super.run, passing along the parameters passed to it.

    If any invocation of beforeAll completes abruptly with an exception, this method will complete abruptly with the same exception. If any call to super.run completes abruptly with an exception, this method will complete abruptly with the same exception, however, before doing so, it will invoke afterAll. If afterAll also completes abruptly with an exception, this method will nevertheless complete abruptly with the exception previously thrown by super.run. If super.run returns normally, but afterAll completes abruptly with an exception, this method will complete abruptly with the same exception.

    This method does not invoke either beforeAll or afterAll if runTestsInNewInstance is true so that any side effects only happen once per test if OneInstancePerTest is being used. In addition, if no tests are expected, then beforeAll and afterAll will be invoked only if the invokeBeforeAllAndAfterAllEvenIfNoTestsAreExpected flag is true. By default, this flag is false, so that if all tests are excluded (such as if the entire suite class has been marked with @Ignore), then side effects would happen only if at least one test will ultimately be executed in this suite or its nested suites.

    testName

    an optional name of one test to run. If None, all relevant tests should be run. I.e., None acts like a wildcard that means run all relevant tests in this Suite.

    args

    the Args for this run

    returns

    a Status object that indicates when the test started by this method has completed, and whether or not it failed .
