waitForNodeStartup should now throw after 2 minutes rather than 20 seconds. Some bank devs were finding integration tests failing as nodes had still not started...
Added getFreeLocalPorts() for grabbing more than one port. Fixes bug in freeLocalHostAndPort() where the same port can be picked multiple times.
In README.md instruct users to grab IntelliJ16 instead of 15.
This moves a lot of the test support code into its own package which is only imported for tests,
so it's not shipped as a part of core Corda. The node currently depends on this support code to
compile, although future work could try to separate this out. This change highlights that parts
of production code is dependent on test elements (i.e. dummy keys), and makes it harder for
such accidental crosses to occur later.
An integration test category is also added as part of this work, to contribute towards COR-345.
