Quality assurance is an important process in the software development process. It is also the most important link to pay attention to. First of all, we must distinguish QA from the testing department or the system testing and maintenance testing department. This is an easy-to-understand mistake.I. QA responsibilities.A. Helps pm to crop general regulations and templates at the organization level.B. participate in software reviews.C. Approve and review

Lossless assurance of virtual networks-zOVN, virtual lossless-zovn Note:ZVALEThis is also an article published by the IBM Research Institute, which may be an extension of VALE. Currently, the data center network is dominated by two trends. One is for Lossless layer-2 fabrics, which is based on enhanced Ethernet and infiniband, by improving performance and performance. On the other hand, it is based onSoftware Defined NetworkThis makes it possible for

This is not supposed to occur in the investigation process, it will arouse the strong resentment of others.3. Several common ways to survey questionnaires　　A. Single-choice questionsB. Multiple choice questionsC. The question of openness4. Significance of the questionnaire　　Questionnaire Survey is a research method of discovering demand, the biggest goal is to get "what the user needs most", for the

deployment Diagram ( tasks assigned to the project this week)I. Introduction to the deployment diagramThe deployment diagram is used to describe the structure of the system at runtime, showing how the hardware is configured and how its software is deployed to the network architecture. From the deployment diagram, we can learn about the physical relationships between software and hardware components.Ii. composition of the deployment diagram1. Junction pointsA node, usually described as a three-di

When to start designing the user experience in the actual project: the user's first impression, the user's point of view, software Ah service always remember the user's choice; short-term stimulation and long-term impact2. Test Experience Exchange: basic terminology interpretation and classification, according to test design method classification, according to the purpose of the test classification, according to the timing and role of testing classification;3. Development phase: For each succ

of that type would be killed. Note: If the pod process is using more than pre-set limites rather than node resource constraints, the system tends to reboot the container or native or other to recreate a pod on its original machine. Use recommendations if you have sufficient resources, you can set the QoS pods type to guaranteed. Use computational resources to change business performance and stability, reducing the time and cost of troubleshooting. If you want to improve resource utilization bet

SummaryDue to the database-level read and write concurrency, the problem caused by inconsistent database and cache data (essentially a read request that occurred after the first return), may be resolved by two minor changes: (1) Modify the service connection pool, ID pick-up service connection, to ensure that the same data read and write fall on the same back-end service (2) Modify database DB connection pool, id modul

testing means checking and verifying the smallest testable unit in the software.The pile module refers to the module called by the analog module, the driver module refers to the upper module of the Model test module, the driver module is used to receive the test data, the module is started and output results.(2) Integration testing, is the next stage of unit testing, refers to the unit module through the test assembly into a system or subsystem, and then test, focus on testing the interface dep

Storm guarantees that every message sent out by spout will be fully processed. This article describes how storm is implementing this assurance mechanism and how we benefit from Storm's reliability as a storm user. meaning of the message being "fully processed" A tuple (tuple) sent out by spout triggers the generation of more tuples downstream. Let's look at your topology of this stream word count: Topologybuilder builder = new Topologybuilder (); Bu

very common, in order to prevent the same business is repeatedly executed, such as an order may be multiple payments, repeated deduction of money, we can be effectively avoided through this scheme, such as when the same order to pay the second time, because the order number and the last time the same, The business type is also the order payment, so when the "token service" is invoked, it is checked that the business has already created the token ID, and the status is accepted, at this point, th

1. What are the methods for estimating software workloads?Two commonly used methods of estimation:Method for estimating Pert sizingPert sizeing is a weighted average method that can be used to estimate the workload of a software project. In estimating each task, the first estimate is given in the best, probable and worst three cases, recorded as A,b,c;The expected value is then calculated using the following formula, the so-called final estimate:Expected value = (A+4*B+C)/6Delphi Estimation Meth
