我能为量角器测试处理一个特殊的茉莉花错误吗
Can I handle a particular jasmine error for protractor tests?
我们有一些监控测试，它们按计划连续执行，有时由于未知的网络相关错误而失败。
修复随机网络错误是首要任务，但与此同时，我正在考虑优雅地处理这种错误——无论是在量角器上还是在茉莉花上。
错误消息总是一样的，所以我想知道是否有办法通过量角器配置文件或其他地方来处理这个错误？
例如：
expect(obj1).isEqual(obj2)
当出现真正的故障时，jasmine会发出类似的错误信息
obj1 is not equal to obj2
当出现具有一致消息的随机网络错误时，jasmine会打印出看起来像的错误
Unable to connect to network. It may be busy now so please try later (example message)
我想覆盖所有的jasmine错误，只忽略示例消息的失败报告。

感谢@alexe在跟踪日志中提供线索。可能是基本的，但仍然想回答，希望能帮助到别人。
由于我使用Jasmine 1.3，我在minijasminenode''lib''Jasmine-1.3.1.js中找到了许多地方可以覆盖故障，但我发现覆盖的最佳位置如下：
jasmine.Spec.prototype.fail = function (e) {
if(e.message && e.message.indexOf('timed out after')>=0) {
console.log("EXCEPTION MSG " + JSON.stringify(e, null, 4));
var expectationResult = new jasmine.ExpectationResult({
passed: true,
message: 'Skipped for proxy error',
trace: { stack: e.stack }
});
}
else {
var expectationResult = new jasmine.ExpectationResult({
passed: false,
message: e ? jasmine.util.formatException(e) : 'Exception',
trace: { stack: e.stack }
});
}
this.results_.addResult(expectationResult);
};
