当测试失败时,TravisCI 不会让我的构建失败

TravisCI is not failing my build when tests fail

我用 JavaScript 编写了测试,我使用 TravisCI 进行测试。

设置

我的 package.json 是这样的:

"scripts": {
  "test": "node testsRunner.js"
}

而我的 .travis.yml 是:

language: node_js
node_js:
- '0.12.7'

'testsRunner.js' 是:

var nodeunit = require('nodeunit');
var path = require('path');

nodeunit.reporters.default.run([
  path.join(__dirname, 'suite1/test.js')
]);

suite1/test.js最后是:

module.exports = {
  setUp: function(callback) {
    // Initialization code...
    callback();
  },

  tearDown: function(callback) {
    // Cleanup...
    callback();
  }, 

  test1: function(test) {
    test.expect(10); // This test expects 10 assertions to be run
    // Doing stuff...
    test.done();
  },

  test2: function(test) {
    test.expect(10); // This test expects 20 assertions to be run
    // Doing stuff...
    test.done();
  }
};

问题

问题是test1成功而test2没有通过。在 test2 抛出异常之前,Travis 报告我的构建失败。

但是现在我修复了测试,所以 test2 不会抛出异常,但它的断言会失败。然而,Travis 将该构建报告为通过,而它应该将其报告为失败构建。

如何处理?

编辑

我已经像这样改变了我的跑步者:

var nodeunit = require('nodeunit');
var path = require('path');

nodeunit.reporters.default.run([
  path.join(__dirname, 'suite1/test.js')
]);
console.log('Done!'); // ADDED THIS LINE

好吧,在日志中我可以看到 Done! 显示在所有内容之前,之后我可以看到每个单独的测试日志和堆栈跟踪。这些测试是否可能正在执行异步,这导致主进程以 0 状态退出?

固定

根据 Chris Beck 的建议,我将转轮更改为:

var nodeunit = require('nodeunit');
var path = require('path');

nodeunit.reporters.default.run([
  path.join(__dirname, 'suite1/test.js')
], null function(data) {
  // `data` has a value if errors occurred
  if (data) { throw 'Error1'; } 
});

通常有通过 JUnit 进行单元测试集成的插件 xml。这是 travis ci 中的默认值吗?您是否使用 Junit 报告您的测试?

nodeunit 有一个内置的 junit 记者:

junit - Creates jUnit compatible XML reports, which can be used with continuous integration tools such as Hudson.

我使用 travis-ci 进行单元测试。

如果您希望测试失败代表构建失败,调用测试的命令行实用程序需要报告非零错误代码结果(如 bash 值中可见 $? 在 运行 测试之后。)

如果你的 js 环境不会导致 assert 失败,那么最简单的事情很可能是编写你自己的 assert 函数,它会抛出一个未捕获的异常,或者,它设置一个全局变量来指示失败,并且在之前存在你的测试 运行ner 脚本检查全局变量并在设置时抛出未捕获的异常。

(后者的优点是你 运行 所有测试即使某些断言失败,但缺点是如果测试无限循环那么即使在较早的断言失败之后你的构建也会停顿一段时间.)
