the service from another target machine.After the testers recently updated the offline test CI environment to this mode, testers generally reported that the update operation was easier than before. Construction operations can also be omitted, when the developer in the joint environment Self-test completed, the tester directly in the dashboard to obtain the latest development of the mirror image address, replace the mirror address to complete the serv

The choice of the common LAN access Wan method, the LAN access Wan method, as the name suggests, the choice of LAN access Wan is to intervene in the internet. This article also introduces more popular related knowledge in the market. This topic is to discuss how a LAN can access the WAN Internet after the LAN is built. Virtual scenario: A Master Ethernet with 200 MB data points. To meet work requirements, the company plans to use the ddnleased line to connect the LAN to the WAN Internet, and use

: transmits only one color light;DS0 is a 64 K channel, divided by time slot, called time division multiplexing (TDM );China's ISDN adopts the E1 standard;The biggest benefit of PPP is compression and verification;CDP is a layer-2 protocol, and the underlying layer must support SNAP;Line protocol down: verification fails, compression fails, and layer-2 encapsulation protocols are different;PPPoE authentication and negotiation are on the second layer,

traditional fixed network terminal access and fixed network service experience based on the IMS architecture is also one of the main topics currently studied. The European tispan Standards Organization has introduced descriptions of the PSTN and ISDN simulation subsystems in the definition of NGN based on the IMS architecture. The PSTN/ISDN simulation subsystem simulates the PSTN/

Testing tools are the means to achieve automated testing. The rational use of testing tools can not only improve the network diagnostic capability, but also facilitate network management. Generally, broadly speaking, network testing tools can be divided into physical cable tester, network operation simulation tool, protocol analyzer, dedicated network testing equipment, network protocol consistency testing tool, and network application analysis testin

　　Purpose: ● Defined by ProjectTestTest the process. A test plan and test cases are developed by a test group independent of software developers and a test report is submitted. Roles and responsibilities: ● Project software Manager (Development Manager): Reviews test cases, and integrates the content to be tested into the test environment. ● Testers: responsible for completing test case design,Integration TestBuild Environment, perform integration testing, verify problems, and write test reports

There seems to be a quarantine bar between the programmer and the tester. Maybe I am too sensitive ...... Starting from the current division of labor in the company, I have heard many people complain to me. From Requirement Analysis to product delivery, a project in a small company is usually handled by one person, this is true even for some large companies. It also includes testing. In this case, there is no so-called division of labor. It is nothin

The first is an attribute, and the other two are methods. In addition to the three variables, I would also like to discuss the special variable arguments, which is slightly different from Function. prototype. arguments (discarded. First, I will define a "tester" function to help us figure out what happened. ; html-script: false ]var tester = function (a, b, c){ console.log({ this: this, a:

of an application with different browsers on different devices, because it is too costly to establish a lab and deploy human resources without a large number of devices. Crowdsourcing testing activities can help to cope with certain difficulties, such as getting users from different places and testing versatility on multiple devices. Crowdsourcing testing has been gaining momentum recently because the value produced by groups can be achieved by an internal testing team. Group testing cannot rep

in this particular network environment. The network standard defines the end-to-end connection specifications for the cable medium used in the network. Network standards are especially useful when you need to know whether a network fault is caused by a cable. Currently, most common networks run at 10 Mbps. 650 or 652 of existing low-price cable testers, such as Fluke, is used to test whether these cables comply with network standards. These cable testers provide automated testing capabilities t

1. When do testers need to participate in requirement analysis? In principle, the deeper the tester understands the requirements, the more favorable the testing work. Therefore, it is best to participate in the requirement analysis work from the very beginning. This can bring the following benefits: Testers participate in the demand analysis throughout the process and have a deep understanding of the requirements, which reduces the interaction with de

A lot of data, interface type This is a pointer, all cannot use a pointer to an interface type. Don't understand In order to better understand interface, we use a demo to understand what interface memory does. type tester interface{ t

according to 20% of all information points. After acceptance, technical personnel are responsible for routine maintenance and management of the network. Testing Instruments and testing standards Before testing, we need to select appropriate testing instruments and testing standards. Generally, we use internationally recognized testers for testing. For example, when testing copper cables, we use a cable test table for basic connectivity (on) testing. When testing Category 5 lines, we used the Mi

SDH is the most widely used optical transmission network. It features high bandwidth, strong anti-interference, and high scalability.In a specific network connection, the general service provider places the cable at the user's place, and the user places the cable with a modulation device (common Modem , DTU or baseband modem), and then our network edge settings (usually vrouters) are connected with the modulation device. But some lines A vro has a built-in device that can directly connect to the

Asyuncrical Digital Subscriber Loop Asymmetric Digital user line loop (ADSL) is a member of the XDSL family and is hailed as "express on modern information highway" by Western countries ". Because of its high downlink speed, high frequency bandwidth, and excellent performance, it is favored by many users and has become another new and faster and more efficient access method after modem and ISDN, it is also the most widely used access method in China.
