Action: runBlockTest,
Name: "blocktest",
Usage: `loads a block test file`,
Description: `
The first argument should be a block test file.
The second argument is the name of a block test from the file.
The block test will be loaded into an in-memory database.
If loading succeeds, the RPC server is started. Clients will
be able to interact with the chain defined by the test.
