The primary reason to decouple deploying and wrapping functionalities is that some use cases require these steps to be performed by separate applications, and different moments in time. For this reason, whatever is returned by the deploy methods should be serializable. After deserialization at some later time, it should then be valid input for the wrap method. The Codex continuous tests system is a clear example of this use case: The `CodexNetDeployer` tool uses deploy methods to create Codex nodes. Then it writes the returned objects to a JSON file. Some time later, the `CodexContinousTests` application uses this JSON file to reconstruct the objects created by the deploy methods. It then uses the wrap methods to create accessors and interactors, which are used for testing.

@ -21,7 +21,7 @@ Do you want to write some tests using this distributed test setup? Great! Here's
1. When using the auto-bootstrap, you have no control over the bootstrap node from your tests. You can't (for example) shut it down during the course of the test. If you need this level of control for your scenario, use the `CodexDistTest` instead.
1. If your test needs a long time to run, add the `[UseLongTimeouts]` function attribute. This will greatly increase maximum time-out values for operations like for example uploading and downloading files.
### Continuous tests
1. Add new code files to `Tests/CodexContinousTests/Tests`
1. Add new code files to `Tests/CodexContinuousTests/Tests`
1. Inherrit from `ContinuousTest`
1. Define one or more methods and decorate them with the `[TestMoment(...)]` attribute.
1. The TestMoment takes a number of seconds as argument. Each moment will be executed by the continuous test runner applying the given seconds as delay. (Non-cumulative. So two moments at T:10 will be executed one after another without delay, in this case the order of execution should not be depended upon.)
