我正在努力让 Travis CI 使用 Sauce Labs 运行 Protractor 测试。隧道工作正常，我的 Express 服务器明显启动并保持在 http://localhost:9000 ，但我的 Protractor 测试很快失败，并出现错误 Error: Angular could not be found on the page http://localhost:9000/ : retries looking for angular exceeded 。互联网上的所有建议通常都涉及不使用 Angular 1.0(使用 1.3)、延长超时(这样做)或强制 Protractor 查看 <html>对于 ng-app 指令(这样做)。我没有主意了。
相关配置:
Protractor .conf.js
exports.config = {
sauceUser: process.env.SAUCE_USERNAME,
sauceKey: process.env.SAUCE_ACCESS_KEY,
baseUrl: 'http://localhost:9000',
specs: ['e2e/**/*.spec.js'],
framework: 'jasmine',
maxSessions: 1,
allScriptsTimeout: 30000,
rootElement: 'html',
multiCapabilities: [
{'browserName': 'chrome'},
{'browserName': 'firefox'},
{'name': 'diplomacy'},
{'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER ? process.env.TRAVIS_JOB_NUMBER : null},
{'build': process.env.TRAVIS_BUILD_NUMBER ? process.env.TRAVIS_BUILD_NUMBER : null}
],
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 360000,
includeStackTrace: true
}
}
main.spec.js
'use strict';
describe('Home page', function() {
var page;
beforeEach(function() {
browser.get(browser.baseUrl);
});
it('should pass', function() {
expect(true).toBe(true);
});
});

最佳答案
FWIW，我最终让一切正常工作。我没有做出“单一修复”，因此我无法轻松地阐明解决方案。以下文件是from my repository with which I set up continuous integration .
