# 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/).

## Installing [Buck](https://buckbuild.com/)

Follow the instructions
[here](https://gerrit-review.googlesource.com/Documentation/dev-buck.html#_installation)
to get and install Buck.

## Local UI, Production Data

This is a quick and easy way to test your local changes against real data.
Unfortunately, you can't sign in, so testing certain features will require
you to use the "test data" technique described below.

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

This is required for running the `run-server.sh` script 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/)

Then add go to your path:

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

### Running the server

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

```sh
./run-server.sh
```

Then visit http://localhost:8081

## Local UI, Test Data

One-time setup:

1. [Build Gerrit](https://gerrit-review.googlesource.com/Documentation/dev-buck.html#_gerrit_development_war_file)
2. 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

## Running tests (bazel)

Run

```sh
WCT_ARGS='--some-flag' sh polygerrit-ui/app/run_test.sh
```
