Building and Testing Business Service

This document describes how to set up your development environment to contribute to swyp business frontend service. It also explains the basic mechanics of using git, node, and npm.

Prerequisite Software

Before you can contribute to the application, you must install and configure the following products on your development machine:

  • Git.

  • Node.js, (version specified in the engines field of package.json) which is used to run a development web server, run tests, and generate distributable files.

  • Yarn (version specified in the engines field of package.json) which is used to install dependencies.

Getting the Sources

Fork and clone the application repository:

  1. Login to your bitbucket account and fork the application
  2. Clone your fork of the application repository to your local system and define an upstream remote pointing back to the main application repository that you forked from in the first place.
# Clone your GitHub repository:
git clone git@bitbucket.org:oracka/business-frontend-service.git

# Go to the appplication directory:
cd business-frontend-service

# Add the main  repository as an upstream remote to your repository:
git remote add upstream git@bitbucket.org:oracka/business-frontend-service.git

Installing NPM Modules

Next, install the JavaScript modules needed to build and test Angular:

# Install application project dependencies (package.json)
yarn install

Submitting a Pull Request (PR)

Before you submit your Pull Request (PR) consider the following guidelines:

  1. Make your changes in a new git branch:

    git checkout -b new-feature-name-goes-here develop
  2. Code the functionality or create your patch, including appropriate test cases.

  3. Follow our Coding Rules.

  4. Run the full test suite, as described in the Test Rules, and ensure that all tests pass.

  5. Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages.

    npm run commit
  6. Push your branch to GitHub:

    git push origin
  7. In bitbucket, send a pull request to business-frontend-service:develop.

  • If we suggest changes then:

    • Make the required updates.

    • Re-run the whole test suites to ensure tests are still passing.

    • Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

      git rebase develop -i
      git push -f

That's it! Thank you for your contribution!

After your pull request is merged

After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:

  • Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:

    git push origin --delete new-feature-name-goes-here
  • Check out the develop branch:

    git checkout develop -f
  • Delete the local branch:

    git branch -D new-feature-name-goes-here
  • Update your develop with the latest upstream version:

    git pull --ff upstream develop

Coding Rules

To ensure consistency throughout the source code, keep these rules in mind as you are working:

  • All features or bug fixes must be tested by one or more specs (unit-tests).
  • All public API methods must be documented. (Details TBC).
  • We follow AirBnb js-style-guide, but wrap all code at 100 characters. An automated formatter is available, see DEVELOPER.md.

Commit Message Guidelines

We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the application change log.

Commit Message Format

Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.

The footer should contain a closing reference to an issue if any.

Samples: (even more samples)

docs(changelog): update changelog to beta.5
fix(release): need to depend on latest rxjs and zone.js

The version in our package.json gets copied to the one we publish, and users need the latest of these.

Revert

If the commit reverts a previous commit, it should begin with revert:, followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.

Type

Must be one of the following:

  • build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • docs: Documentation only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • test: Adding missing tests or correcting existing tests

Scope

The scope should be the name of the file(s) affected (as perceived by the person reading the changelog generated from commit messages.

There are currently a few exceptions to the rule:

  • changelog: used for updating the release notes in CHANGELOG.md
  • none/empty string: useful for style, test and refactor changes that are done across all packages (e.g. style: add missing semicolons)

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize the first letter
  • no dot (.) at the end

Body

Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.

Footer

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.

A detailed explanation can be found in this [document][commit-message-format].

Editor Setup

Before editing or adding new code to the code base ensure that your ide or editor of choose has the following installed and enabled.

  • tslint

Building

To build application run:

$ npm run build
  • Results are put in the dist folder.

Running Tests Locally

To run tests:

$ npm run test             # Run all application tests on node

You should execute the 3 test suites before submitting a PR to github.

See DEBUG.md for information on debugging the code while running the unit tests.

All the tests are executed on our Continuous Integration infrastructure and a PR could only be merged once the tests pass.

  • CircleCI fails if your code is not formatted properly,
  • Travis CI fails if any of the test suites described above fails.

Formatting your source code

The Application uses eslint to format the source code. If the source code is not properly formatted, the CI will fail and the PR can not be merged.

You can automatically format your code by running:

$ npm run watch-debug

Linting/verifying your source code

You can check that your code is properly formatted and adheres to coding style by running:

$ ThankGod what command should i run here please?

Understanding Trello Pipelines

  • New Issues: New issues (in user story format) land here automatically. They are to be dragged to another pipeline as soon as possible.

  • Project backlog: Issues that are about to receive attention (Only project owner moves issues to the pipeline) Issues here are to be estimated by the developer designated to work on it. Once it has been estimated it is ready to be added to the strint backlog pipeline.

  • String Backlog: Issues here have been estimated and are part of a milestone to be delivered in at the end of the next sprint circle.

  • In progress: List of all task that has been started for the current sprint circle.

  • Ready for QA: All test here are ready to be tested.

  • Done: All Issues here have been merged to develop branch and ready to be shipped.

  • Closed: Issues here are either complete or are not going to be done.

  • Icebox: Issues here have no immediate value for the app or the priority level is very low

Understanding Trello Board Labels

  • Red label = Bug.
  • Yellow label = Design work.
  • Pink label = Engineering.
  • Purple Label = Help needed.
  • Blue Label = Front end work.
  • Green Label = Discussion.
  • Brown Label = Feature.
