Intermittent Travis CI Issues #36

Hopefully not as flaky as thought 😎

Clue: npm install and npm test both succeed on local ubuntu VM, but the missing dependency is highlighted as an issue there as well. Some code in a dependency might be importing different packages at runtime based on some criteria that differentiates between the Travis CI VM and the local VM I'm testing with: $ npm ls typedarray-to-buffer
@hyperledger-labs/blockchain-integration-framework@0.1.0 /REDACTED/blockchain-integration-framework

Tried upgrading web3 to latest stable but that has another issue that breaks dependencies ( Will try with web3 |
|
I tinkered with the travis build, had to update the web3 version from that beta release to a stable one and put in some shell code to ensure npm dependencies are installed in the example sub-projects as well (fabric/api, quorum/api) There is still the issue of flakiness which is a different one, it appears to be in one of the unit tests, but that doesn't always fail, just sometimes. For now I put the fixed up code here in a draft PR, will hopefully come up with something for the flaky unit test tomorrow: |

Web3 released a fix for the dependency issues in |
Also a list of other changes that were required to make the CI green: - clean up steps in the script: remove .git folder of websocket package - install npm dependencies in the fabric and quorum api folders - update web3 to 1.2.4 - update the post install patching of web3 formatter to match v1.2.4 - clean up: run "down" npm script for fabric and quorum - force volume re-creation when calling docker-compose up Also: the CI script is now in a separate .sh file so that it can be invoked locally on any dev machine that has the dependencies pre-installed Fixes #12 Fixes #36 Signed-off-by: Peter Somogyvari <peter.somogyvari@accenture.com>
