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

Fluke Networks (Fluke Network) has launched an ethernet cable tester "DTX-1800", in addition to the widely used "5e" line, it can also be used to detect "6" and "7" lines with better transmission characteristics. You can check whether the cables used as the measurement object meet the corresponding specifications. The testing frequency is up to 900 MHz. Reduce the testing time of the "6" line to 12 seconds, less than 4300 of the latter, compared to ab

training opportunities, to start asking for help.So, I am a university to avoid the computer course study, and even the operating system is what ghosts are not clear of the guy, to open that small black window, began to lose command.Then, the story is usually the beginning.I will learn some of my knowledge, all recorded in this blog, although we all feel that only the people can be very sweet to write a blog, but I do not think. Most of the time I hope to find some basic, understandable things

problems a lot of companies have a very good solution in fact, test students, I am more looking at the test thinking!Not all students are suitable for testing and testing the introduction is very simple casually to a person, point will test the casual training for a few months, will be tested but that's not the testers I want!-------over today this topic, actually did not go in-depth to throw, we leave a message to discuss the next time to continue in-depth analysis of Lao Xu's point of view! －

course, there are rules for testing. Software testing requires a solid theoretical foundation and solid working ability. You need to read the customer requirement analysis documents, product manuals, project schedules, software design documents, and write test plans and test cases, defect report, useAutomated TestingTool, which requires clear measurement statistics and summary. In fact, it is impossible to perform a full test of the program, and software testing is risky. Of course, testing can

all of them, you need to think about them and think about them with an absolute dedication. It is a kind of creation. It is not clear if you copy the entries in the planning case. Instead, the functional points in the planning case are constantly divided until they are accurate to an input and output result. This is a process in urgent need of mental work. On the one hand, we must affirm the correct content in the planning case, and on the other hand, we must consider whether there are any abno

Regular Expressions are mysterious and obscure. First, you need to systematically learn the knowledge of regular expressions. In the so-called sense, to do a good job, you must first sharpen the tool. To learn a regular expression, you must test whether the regular expression is correct. So we found the code example ts RegEx tester test function. The comment on this tool is pretty good. This little tool is running well in my notebook. However, w

Before answering all questions, we should first find out a question. What capabilities should we need as a whole?I think that as a tester, I should have four aspects of knowledge: Testing basics, industry business reserves, testing tools and technology, testing management capabilities and experience.The above four aspects are also the reference for the promotion of testers. Of course, the basis of the test depends on the number of reserves. The other

Ruby is the hottest language in web development at the moment, simple, flexible, relaxed, and fun. In this year's automated test project, the RFT was used to build the test framework, and the identification of some OCX controls in the page was identified by Ruby. In this case, y
