api performance testing using jmeter

The development tools built into each major browser provide a console object. It has two main functions: Displays the error message when the Web page code is run. Provides a command-line interface for interacting with Web page code. Let's look at how to use the console for performance testing in detail below. For front-end developers, often in the development process to monitor the value of some expression

Use IE to access the tested site (my Ie11,edge browser is the same), navigate to the page you want to test the action on, or the previous page of the page being tested. Press F12 to bring up developer tools, other features I'm not going to introduce, switch directly to the Performance tab.Follow the prompts by pressing the shortcut key Ctrl+e or by clicking the Start button in the upper left corner for analysis.Then on the page to be tested, here my a

); } function Bar (a) {return tracer (a); } var a = foo (' tracer '); Table Using console to render an object in a table You can output incoming objects, or arrays, in tabular form, which is more suitable for objects or arrays of internal elements than traditional tree output, or there may be a lot of undefined. var people = { Flora: { name: ' Floralam ', age : ' A ' }, John: { name: ' Johnma '

In general, we cache the array into a file, the first to be converted into a string form, and then into the text file, there are generally two mechanisms to convert the array into a string, The first is $str = Var_export ($arr, true);The second type is$str = serialize ($arr); The strings after the conversion of these two mechanisms are not the same, the first is the prototype pattern of the array, and the second is the serialized form. The first deposit in the file as long as the addition of ?
