Every day when I look at the templates on the ThemeForest, I test the compatibility of the browser-not to mention my own work. Over time, I've collected the best validation and browser compatibility testing tools on the Web, and here's my favorite.
HTML and CSS Validation
First let's take a look at how to verify HTML and CSS. I should say that because I work on a Mac, I have a slight bias towards the Mac. Don't worry, there are still a number of pla
The Uptime command of the Linux performance testing tool displays how long the server has been running, how many login users there are, and the overall load average evaluation of server performance ). The load average value records the number of processes waiting for execution in the queue for the last 1 minute, 5 minutes, and 15 minutes respectively ).

In Linux, there are many small workers who conduct stress tests on the web, and more famous are AB. although AB can run on Windows, it is a bit difficult for friends who want to operate on a simple interface. in fact, vs.net also provides the stress test function, but it is obviously too heavy. During the test, it also occupies a large amount of resources, resulting in unsatisfactory testing results.To make web stress

Brief introductionMulti-mechanize is an open-source performance and load testing framework that concurrently runs multiple Python scripts to generate load on a Web site or service (a composite transaction). The test output report is saved as HTML or JMeter-compatible XML. Multi-mechanize is most commonly used for Web performance and Scalability (scalability) testing, and also for any API that Python can acc

Two problems that must be understood before you begin:
1. Recording alone is not enough.
2. Not everyone can perform automated testing.
After understanding the previous two questions, I began to learn a tool:
1. Read the help documentation of the tool.
2. Familiar with programming languages
3. participate in online forums
4. Find a small project traine
running the program, you can avoid bugs to the maximum extent possible.
3. think that unit test code writing is boring. Programmers solve the problem by nature. many programmers think that unit test code writing is boring during intense coding. However, if you can discover as many errors as possible in the code by writing unit tests at an early stage, it will save time and reduce the number of errors. why not?
