latter one is applicationcontext.xml configuredBut the @get method is not directly in the path central to obtain, to borrow external tools or write a test class, of course, I chose the former, online Baidu found the big God said postman Google browser plug-in , their own groping to test, no longer worry about interface debugging.The Get interface is as follows:650) this.width=650; "src=" Http://s2.51cto.co
We know that when writing each class, we need to test whether the class has errors. by writing a main () method in each class, we have a disadvantage, that is, the additional code that has been compiled must be carried with it. If this is troublesome for you, you can use Nested classes to place the test code.

调试十分困难。 Because the page may have a lazy load situation. Although the page has been rendered, there may be ajx lazy loading. Some elements need to wait until the AJAX call is complete before they can be displayed. At this point, you need to add a wait mechanism on the page./** * 用于等待某个元素出现,软等待 * @param by */public boolean wait(final By by){ new WebDriverWait(driver, 10).until(new ExpectedConditionFor example, you want to find an element that id= "name":if (wait(By.id("name"))) xxx;else

disk spaceHow to locate these performance issues: 1. Check the system log, log is the Magic weapon to locate the problem, if the full log records, it is easy to find the problem through the log.For example, when the system goes down, the system log prints out an out-of-memory error when a method executes, and we can follow the lead and quickly locate the problem that caused the memory overflow.2. Using performance monitoring tools, such as: Java Deve

In some cases, we need to unit test our own code (the benefit is to reduce the effort and expense of late maintenance), which is some of the most basic module tests. Of course, in the case of unit testing, it is necessary to understand the internal logic implementation of the code we test, so that we can clearly compare the results we expect from the code logic implementation to the actual results of the
