regex tester

Regex usage in MongoDB Background Part1: Preface Anyone who uses MySQL or other relational databases knows that fuzzy queries are used in similar ways:SELECT * FROM products WHERE sku like "% 789 "; The regex in MongoDB described in this article implements similar functions. regex enables you to use regular expressions in queries. This article will use a simple e

problems! If your network has both wired and wireless, you need a tool that can diagnose both wired and wireless networks. Through rapid network search and fault diagnosis, elasticsearch can quickly find the cause of Wired/wireless network faults to ensure the normal operation of the network. It helps you optimize your network and make your work better. As a portable tester, the elasticsearch network is easy to carry and use. It also provides powerfu

working HUB. Identifying the cable link from the distribution frame microcable Pro can also provide office/room recognition, which can provide cable Direction recognition when adding, moving, and changing office sites. It helps identify the position of cables on the distribution frame and makes it easy to test and file twisted pair wires and coaxial cables. Audio function tracking and positioning cable the audio function of microbench Pro can generate audio signals, use the audio detector optio

Before answering the question of whether you want to be a generalist, we should first figure out a problem, what capabilities should you need as a generalist?I thinkas a tester, you should have four knowledge: testing fundamentals, industry business reserves, test tools and techniques, test management capabilities and experience. The above four is also a reference for the test staff promotion, of course, we have to test the basis of the number of rese

Test tool in the eyes of a practical Tester Chen nengtech 2007-9-5 Excellent testers are developed and need internal skill, external skill and weapon. The cultivation of internal strength, that is, the study of testing theory, has been mentioned in the test theory in the eyes of the practical tester. Here, let's take a look at the 18 weapons. How can our testers make good of them? Dialectical attitud

the signal emits locally and is measured remotely. Fext is not very valuable in itself. Because the fext is influenced by the length of the cable link, the signal intensity including crosstalk will be affected by the attenuation after the signal source is emitted. It is also the reason that measuring the equivalent distal crosstalk (elfext) is more meaningful. The effect of attenuation is considered in the elfext result, so this parameter is more practical. For the same reason, there are also

Recommendation 64: Increase the tester-doer mode for loops instead of placing the try-catch inside the loopIf you need to throw an exception in a loop, you need to be particularly careful that throwing an exception is a fairly performance-impacting process. You should try to judge some of the conditions of the anomaly in the loop and then process it according to the conditions.Do a test:Stopwatch Watch =stopwatch.startnew (); intx =0; for(inti =0; I

optical cables can be managed using a single software, and full-line cable Tester of fluke network is supported. Provides professional, customizable, and graphical test reports in common formats for fluke cable tester. Ensure compliance with the standards for configuring and printing the TIA 606-A document The new drag-and-drop feature makes it easier to manage and organize multiple projects. Compatibl

Previously, I was a happy tester in a city in central China. I was not busy at work and curious about all technologies. Tests are neither professional nor important. But I have my own happiness. When I am not busy at work, I will learn Performance Testing + LoadRunner today and learn automatic selenium tomorrow. The boss said, do a performance test on our project. Then, I ran to ask Baidu, Google, and my friends in the group about what tools and envir
