少し遅れましたが、Chromeがヘッドレスブラウザを立ち上げることができるようになったので
ブラウザーテスト駆動を導入してみました。
ローカル環境
mac(macOS 10.13.6)
Node.js(8.9.3)
gulp(3.9.1)
karma(2.0.0)
バージョン管理
GitHub
TravisCI
ローカル環境の準備
1. Node.jsの導入
nvmでNode.jsは管理する
cd ~
git clone https://github.com/creationix/nvm.git ~/.nvm
source ~/.nvm/nvm.sh
nvm install v8.9.3
nvm alias default v8.9.3
macを起動した時に自動でNode.jsが起動するよう設定
vim ~/.bash_profile
下記を追記
[[ -s ~/.nvm/nvm.sh ]] && . ~/.nvm/nvm.sh
nvm use default
npm_dir=${NVM_PATH}_modules
export NODE_PATH=$npm_dir
反映して完了
source ~/.bash_profile
2. gulp & karma
npm install -g gulp karma
必要なライブラリをインストール
npm install browser-sync gulp gulp-concat gulp-uglify jasmine jasmine-core karma karma-chrome-launcher karma-coverage karma-firefox-launcher karma-jasmine karma-spec-reporter --save-dev
3. gulpfile.jsを設定
gulpfile.js
var gulp = require("gulp");
var browser = require("browser-sync").create();
var concat = require("gulp-concat");
var uglify = require("gulp-uglify");
var Server = require("karma").Server;
/**
* server setting
*/
gulp.task("server", function ()
{
browser.init({
server: {
baseDir: "./",
index: "index.html"
}
});
});
/**
* browser reload
*/
gulp.task("reload", function ()
{
browser.reload();
});
/**
* output js file
*/
gulp.task("output", function ()
{
gulp.src([
"src/**/*.js"
])
.pipe(concat("output.js")) // 複数のJSを一個にまとめる
.pipe(uglify()) // 圧縮
.pipe(gulp.dest(".")); // 圧縮したファイルを出力
});
/**
* default setting
*/
gulp.task("default", ["server"], function ()
{
gulp.watch(["src/**/*.js"], ["tdd"]);
gulp.watch(["output.js"], ["reload"]);
});
/**
* test-driven development
*/
gulp.task("tdd", function (done)
{
new Server({
configFile: __dirname + "/karma.conf.js",
singleRun: false
}, done)
.on("run_complete", function (browsers, results)
{
if (results.failed) {
throw new Error("failed");
}
gulp.start.apply(gulp, ["output"]);
})
.on("error", function (err) {
done(err);
})
.start();
});
/**
* Run test once and exit
*/
gulp.task("test", function (done)
{
new Server({
configFile: __dirname + "/karma.conf.js",
singleRun: true
}, done).start();
});
4. karma.conf.jsを設定
karma.conf.js
// Karma configuration
// Generated on Wed Sep 06 2017 20:07:29 GMT+0900 (JST)
module.exports = function(config)
{
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
"src/**/*.js",
"test/**/*.js"
],
// list of files to exclude
exclude: [
],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {
'src/**/*.js': ['coverage']
},
// test results reporter to use
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['spec', 'coverage'],
coverageReporter: {
type: 'html',
dir: 'coverage/'
},
// web server port
port: 9876,
// enable / disable colors in the output (reporters and logs)
colors: true,
// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_INFO,
// enable / disable watching file and executing tests whenever any file changes
autoWatch: true,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['ChromeHeadless', 'FirefoxHeadless'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity
});
};
これで、ローカルの準備が整ったのでgulpを起動して動くか確認。
[00:00:00] Using gulpfile ~/gulpfile.js
[00:00:00] Starting 'server'...
[00:00:00] Finished 'server' after 8.89 ms
[00:00:00] Starting 'default'...
[00:00:00] Finished 'default' after 184 ms

TravisCIの設定
1. .travis.yml
.travis.yml
language: node_js
node_js:
- "8.9.3"
cache:
directories:
- "node_modules"
sudo: required
addons:
chrome: stable
firefox: latest
before_install:
- npm install -g gulp karma
install:
- npm install
before_script:
- "export CHROME_BIN=chromium-browser"
- "export DISPLAY=:99.0"
- "sh -e /etc/init.d/xvfb start"
- sleep 3
2. package.json
package.json
{
"directories": {
"test": "test"
},
"scripts": {
"test": "gulp test"
}
}
これで完了、ローカルではファイルを変更時に、コミット後はTravisCIで自動テスト
ブラウザテストできるのは助かる
