# PolyGerrit

## Installing [Node.js](https://nodejs.org/en/download/)

```sh
# Debian/Ubuntu
sudo apt-get install nodejs-legacy

# OS X with Homebrew
brew install node
```

All other platforms: [download from
nodejs.org](https://nodejs.org/en/download/).

## Optional: installing [go](https://golang.org/)

This is only required for running the ```run-server.sh``` script for testing. See below.

```sh
# Debian/Ubuntu
sudo apt-get install golang

# OS X with Homebrew
brew install go
```

All other platforms: [download from golang.org](https//golang.org/)

# Add [go] to your path

```
PATH=$PATH:/usr/local/go/bin
```

## Local UI, Production Data

To test the local UI against gerrit-review.googlesource.com:

```sh
./polygerrit-ui/run-server.sh
```

Then visit http://localhost:8081

## Local UI, Test Data

One-time setup:

1. [Install Buck](https://gerrit-review.googlesource.com/Documentation/dev-buck.html#_installation)
   for building Gerrit.
2. [Build Gerrit](https://gerrit-review.googlesource.com/Documentation/dev-buck.html#_gerrit_development_war_file)
   and set up a local test site. Docs
   [here](https://gerrit-review.googlesource.com/Documentation/install-quick.html) and
   [here](https://gerrit-review.googlesource.com/Documentation/dev-readme.html#init).

When your project is set up and works using the classic UI, run a test server
that serves PolyGerrit:

```sh
buck build polygerrit && \
java -jar buck-out/gen/polygerrit/polygerrit.war daemon --polygerrit-dev \
-d ../gerrit_testsite --console-log --show-stack-trace
```

## Running Tests

One-time setup:

```sh
# Debian/Ubuntu
sudo apt-get install npm

# OS X with Homebrew
brew install npm

# All platforms (including those above)
sudo npm install -g web-component-tester
```

Run all web tests:

```sh
buck test --no-results-cache --include web
```

The `--no-results-cache` flag prevents flaky test failures from being
cached.

If you need to pass additional arguments to `wct`:

```sh
WCT_ARGS='-p --some-flag="foo bar"' buck test --no-results-cache --include web
```

For interactively working on a single test file, do the following:

```sh
./polygerrit-ui/run-server.sh
```

Then visit http://localhost:8081/elements/foo/bar_test.html
