 Overview

We describe here a technique for implementing a GigaSpaces integration (i10n) test using a scalatest FunSuite.

 Usage

We provide an abstract FunSuite that is a BeforeAndAfterAllConfigMap in this gist. Simply implemented, the subclass need only provide a small number of properties and a Spring context file. The superclass uses this information to seed a ConfigMap, which then configures a nested ProcessingUnitContainerProvider, which in turn provisions a protected GigaSpace proxy.

Here's example configuration from a working example that tests against an embedded SpaceClosed Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model.:


  // "defaults" is a protected member, and is 
  // the only required configuration necessary to 
  // successfully initialize the FunSuite.
  defaults = Map[String, Any](
    schemaProperty -> "partitioned-sync2backup"
    , numInstancesProperty -> int2Integer(numPartitions)
    , numBackupsProperty -> int2Integer(0)
    , instanceIdProperty -> int2Integer(1)
    , spaceUrlProperty -> s"jini:/*/*/$spaceName" // spaceName is a class member
    , spaceModeProperty -> SpaceMode.Remote
    , configLocationProperty -> "classpath*:/META-INF/Spring/puClosed This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity..xml"
    , localViewQueryListProperty -> List[SQLQuery[_]]()
  )

The number of backups per partition is zero or one.

In this example, the test code truly is an integration test - designed to run against a running data grid. (Note the reference to pu.xml file, which is available on the test classpath.)

We could as easily have run in-process by using SpaceMode.Embedded. This makes IDEClosed Integrated Development Environment. A software application that helps programmers develop software code efficiently. It increases developer productivity by combining capabilities such as software editing, building, testing, and packaging in an easy-to-use application. Example: DBeaver.-driven debugging easier, as it does not incur the workflow overhead of setting up a remote agent or debugger. Here's the code from another working example:

 
   defaults = Map[String, Any](
     schemaProperty -> "partitioned-sync2backup"
     , numInstancesProperty -> int2Integer(numPartitions)
     , numBackupsProperty -> int2Integer(0)
     , instanceIdProperty -> int2Integer(1) // count begins at 1
     , spaceUrlProperty -> s"/./$spaceName" // spaceName is a class member
     , spaceModeProperty -> SpaceMode.Embedded
     , configLocationProperty -> "classpath*:/META-INF/Spring/pu.xml"
     , localViewQueryListProperty -> List[SQLQuery[_]]()
   )

The number of backups per partition is zero or one.

All SpaceModes supported by data gridare enumerated in the abstract FunSuite class (gisted above). For each mode, corresponding configuration can be provided through the defaults property.


  object SpaceMode extends Enumeration {
    type SpaceMode = Value
    val Embedded, Remote, LocalCache, LocalView = Value
  }
