Fix failing tests for users w/o access to the ACCOUNT_PASSWORD env variable. Disable e2e public network tests in Travis pull requests. Exclude lib dir from unit tests.
* Accounts are now encrypted with a strong passphrase.
* The encrypted passphrase is stored in .travis.yml
* Public testnet tests are now run after tests on a private net
During CI tests non-deterministic failures with "no suitable peers available" happened. Reason is a not finished synchronisation after starting of node.
Added and integrated an EnsureSychronization() almost solved it, but overlapped with new added EnsureNodeSync() in merged develop. Failure stayed, so exchange new algorithm in EsureNodeSync() with former one.
This change moves our e2e tests into a separate package to make room for proper unit and integration tests.
This is Phase 1 described in #371.
Changes:
Makefile has separate directives to run unit/integration tests and e2e tests,
CI runs unit/integration tests first and then e2e tests,
E2e tests are in reliability order, i.e. the least reliable tests are run in the end to be sure that nothing else is broken,
Some tests are fixed or quarantined.
