Check points are of the following types: Thread checkpoints is the database check point, which may occur in the following cases: closing the database consistently; alter systerm checkpoint statement; switching online redo log file; alter database begin
There are two types of checkpoints in LR: Pictures and text.Common checkpoint functions are as follows:1) the Web_find () function is used to search for the specified text string from an HTML page;2) the Web_reg_find () function registers a request to search for the specified text string on the HTML Web page retrieved by the next operation function (such as web_url);3) the Web_image_check () function is used to find the specified picture from an HTML
Check points for RddThe RDD cache can be saved to memory, local file system, or Tachyon after the first calculation is completed. With caching, spark avoids repetitive computations on the RDD and can greatly increase the computational speed. However, if the cache is missing, it needs to be recalculated. If the calculations are particularly complex or time-consuming, the impact of cache loss on the entire job cannot be overlooked. To avoid the overhead of cache loss recalculation, Spark introduce
With the rapid development of Internet, how to guarantee the security of information and network, especially in the exchange of confidential information such as commerce in open interconnected environment, how to ensure that information access and transmission is not stolen, tampering, has become a matter of great concern to enterprises.

Determining if the script is successful is determined by the state returned by the server, and if the HTTP status returned by the server is Vugen, then the script is considered to be running correctly and is running. Will the error page code be returned when most systems fail? No, the general system will return a message prompt to enhance the user's feelings. For example, "website busy, please later".In fact, this time the site has been unable to correctly respond to user requests, but the Vugen

The purpose of setting checkpoints is not only to verify that our scripts are correct, but also to make the test results more convincing, therefore, we recommend that you add checkpoint settings in all test scripts.
I. How to set checkpoints
1. Switch the script to the tree structure, find the text you want to check on the page view page, right-click the script, and select Add a text check.
2. Switch the script backCodePage, ma

Checkpoint: For a simple understanding, we have parameterized the user name and password as described in the previous chapter. How can we determine whether jmeter correctly calls the files in test. dat. Of course, we can view it in the result chart. But I still want to check it in the "login" area.
Checkpoints in jmeter are completed by adding assertions.
