问题 I am working on a online file management project. We are storing references on the database (sql server) and files data on the on file system. We are facing a problem of coordination between file system and database while we are uploading a file and also in case of deleting a file. First we create a reference in the database or store files on file system. The problem is that if I create a reference in the database first and then store a file on file system, but while storing files on the file

Does Unit Tests still matter if Functional Tests is satisfied?

阅读更多关于 Does Unit Tests still matter if Functional Tests is satisfied?

问题 For a short summary: Unit tests are the smaller ones that expects something to do it right in dev's view. Functional tests are those that expects things are right in user's view If Functional Tests are already satisfied, do we still need to do Unit Tests? Most likely (let's use web development as context), this is common by using the browser to see if things are right by letting other users/people try the system/application. Let us put out other tests like for edge cases. 回答1: Are there any

问题 I am working on a thesis about meassuring quality of a product. The product in this case is a website. I have identified several quality attributes and meassurement techniques. One quality attribute is "Robustness". I want to meassure that somehow, but I can't find any useful information how to do this in an objective manner. Is there any static or dynamic metric that could meassure robustness? Ie, like unit test coverage, is there a way to meassure robustness like that? If so, is there any

Making all plugin specific rules strict

阅读更多关于 Making all plugin specific rules strict

问题 In eslint.json configuration, ESLint allows to configure rule strictness using the following logic: 0 - "off" 1 - "warning" 2 - "error" Example: { "rules": { "jasmine/valid-expect": 2, "eqeqeq": [2, "smart"] } } Question: Is it possible to make all plugin-specific rules strict (code 2)? In this case, we want all rules coming from jasmine (eslint-plugin-jasmine plugin) produce an error if there is a violation. I've tried to specify "jasmine/*": 2 and "jasmine": 2 , but both failed with a

How to simulate 120 concurrent users of a web application with real conditions?

阅读更多关于 How to simulate 120 concurrent users of a web application with real conditions?

问题 How to you simulate > 120 concurrent users using a Load Test Framework such as JMeter? Real concurrency, as far as I understand, would be possible if I would use 120 servers or 120 CPU cores. How did/do you test your web application or service with real conditions? 回答1: I have found JMeter to work fine, but I generally use is across 4-5 PC's to get the most accurate results. Although you may believe 120 concurrent users may be difficult to simulate from a single PC, you have to realise that

SonarQube - how is it used

阅读更多关于 SonarQube - how is it used

问题 I have a simple problem, with a simple answer probably, but I can't find what is it. We want to deploy SonarQube along with Checkstyle and some other tools, but we can't find out is it meant for a centralized, server deployment, or on each developer machine? All tutorials show installations on separate machines and being used in the localhost, while there is a public instance example, and the requirements and specs certainly look service-like. On the other hand, I'm not getting how do the
