Manual Development Workspace Setup Instructions

Go backend

The Go backend isn't strictly required for all development. Consider running locally with node if you will not be doing primary feature work where you need access to the actual Cloud Foundry API.

Cloning the repository

If you are unfamiliar with Go project directory structure, you want the code in this repository to be in something like <your-code-directory>/src/github.com/18f/cg-dashboard. You can use that exact pattern by cloning the repository with:

git clone [email protected]:18F/cg-dashboard.git src/github.com/18F/cg-dashboard

Set the environment variables

If you are testing locally, export these variables. There is a sample file of environment variables called env.sample. Feel free to copy it and use the proper data. If you've never used environment variables before, you can run the following: mkdir ~/.env && cp ./env.sample ~/.env/cg-dashboard

Then edit the file ~/.env/cg-dashboard and provide the proper values. When you want to set all the environment variables, just run source ~/.env/cg-dashboard. You'll have to do this every time you open a new shell. If you work at 18F, ask a team member to send you the secret credentials.

  • GOPATH: The absolute path to your code directory, one level up from the root of this project. If you followed the cloning instructions above, this path should correspond to the value you used for <your-code-directory>.
  • CONSOLE_CLIENT_ID: Registered client id with UAA.
  • CONSOLE_CLIENT_SECRET: The client secret.
  • CONSOLE_HOSTNAME: The URL of the service itself.
  • CONSOLE_LOGIN_URL: The base URL of the auth service. i.e. https://login.domain.com
  • CONSOLE_UAA_URL: The URL of the UAA service. i.e. https://uaa.domain.com
  • CONSOLE_API_URL: The URL of the API service. i.e. http://api.domain.com
  • CONSOLE_LOG_URL: The URL of the loggregator service. i.e. http://loggregator.domain.com
  • PPROF_ENABLED: If set to true or 1, will turn on /debug/pprof endpoints as seen here

Codecheck

You need to have Docker installed and active within your environment as the unit tests use Docker for short term real instances.

To run the go tests:

$ ./codecheck.sh

fmt can be used to fix any linting errors:

$ go fmt ./controllers

Front end

Front end build commands should be run in the same directory as the package.json file. If you've used the cloning command from this README it should be something like /path/to/cg-dashboard-ws/src/github.com/18F/cg-dashboard. Node version 6 and above should always be used.

Install front end dependencies (may require special steps for node-gyp):

npm install

Build the code:

npm run build

or to continually watch and build with changes:

npm run watch

To run the tests:

npm run test

or to continually watch for changes and run test suite:

npm run watch-test-unit

To lint the code (also run as part of tests):

npm run lint

In order to get correct syntax highlighting with vim, install the following npm modules globally:

npm install -g eslint
npm install -g babel-eslint
npm install -g eslint-plugin-react

Running locally

  • Make sure all of your environment variables are set and you are using the Go version as mentioned above.
  • Install dep
  • Run dep ensure to get all third party code
  • go run server.go
  • Navigate browser to http://localhost:9999

Run locally without needing Go

This is an easy way to test out front end changes without needing to set up environment variables or Go. We will use a small server with fake data (used for automated testing) to get going quickly. If you want to see live data, you'll need to follow the instructions above.

The command npm run testing-server will run the server. We will still be using npm run watch to build the front end application when the file changes.

Start it

  • npm install to get the Javascript dependencies
  • npm run testing-server & npm run watch to start the server and build process

Stop it

Now when you're done, you'll want to stop the testing-server that is running in the background. You can find it by running jobs, and the line that looks like this:

[N] + running npm run testing-server

To kill that process, run kill %N where "N" is the number from the line.

Unit Testing

Running Go unit tests

TEST_ROOT_PATH=`pwd` go test ./...

Running Javascript unit tests

Test can then be run with the command:

npm run test

Functional Tests

Functional tests are our high-level automated UI tests that are run from the browser. They can be slow to run, but often catch issues that only appear when functional components appear together, like when running in a real web browser.

Prerequisites

The tests are based on Webdriver and use the Selenium Standalone server to drive the browsers.

  • Java 8

Setup

You'll only have to do this once. This downloads the browser-specific drivers that we have configured.

$ npm run test-selenium-install

Run the tests

$ npm run test-functional
