#Set up local dynamodb us east n virgina zip file

In August 2018 Amazon announced new Docker image with Amazon DynamoDB Local onboard. PS: I am aware of Alternator, but it appears to have other drawbacks so I’m inclined to stick with Amazon’s supported solution if I can make it work. Can’t I somehow ask the JVM to fork itself and look inside the resources to build a classpath? Or, even better, can’t I just call the main method of DynamoDB Local from some other thread so this all happens in a single process? Any ideas? DynamoDB Local is, after all, just Java code. It seems like there should be an easier way. Besides being slow, the potential for left-over processes seems ugly.

I have to spawn a process and wait for it to start for each unit test, and then kill that process after each test.

Using local disk is often dicey for testing, especially with continuous builds and such.

I have to unpack a zip to the local disk.

Everyone needs the java executable on their $PATH.

That works, but it’s ugly and has some drawbacks:

zip file of the DynamoDB local stuff in test/resources, then in the method, I’d extract it to some temporary directory and start a new java process to execute it. I have found a way to make this work, but it’s ugly, so I’m looking for alternatives. That way anyone pulling down the git repo gets a copy of everything they need to run the tests and each test is independent of the others. Then before each test I’d start it up, running with -inMemory, and after the test I’d stop it. What I want to do is something like put the DynamoDB local jar, and the other jars upon which it depends, in my test/resources directory (I’m writing in Java).

All developers need to have it installed.

The server isn’t started and stopped before each test so tests become inter-dependent unless you add code to delete all tables, etc.

You have to somehow start the server before your tests run.

I’m using DynamoDB local for unit testing.
