Brief introduction:

Environment: Mac OS

Home directory similar to windows self-built directory such as: D:/test/id.txt

The previous article introduced the basic use of jmeter, slightly mentioned how to do parameterization, this article further explained the parameterization.

Jmeter probably has the following parameterization methods:

The use of parameterized scene 1User Parameters is suitable for using 2CSV Data Set Config when the range of parameter values is very small. This method is more flexible. 3User Defined Variables is generally used for parameter settings in Test Plan that do not need to iterate with the request. For example, functions in Host and Port Number4Function Helper can be used as supplements to other parameterized methods, such as ${_ Random (,)} generated by random numbers.

Parameterized meaning:

Parameterization can use different data for a variable. For example, when multiple users place an order to purchase goods, the API for calling and issuing an order is the same, but the user's id is different. The test interface using different users can more realistically simulate user scenarios, and can also be used in multi-user concurrent scenarios.

One definition, multiple uses, one modification, multiple modifications.

Today I'm going to talk about the slightly more complex CSV parameterization.

Continue yesterday's example, right-click thread group-> add-> configure components-> csv Data Set Config

The native home directory creates the file id.csv file, and sets the file directory in csv, as shown in the figure

The id.csv file is as follows:

In id.csv, we set up two different id, and the caller is in the http request

Then set up the thread group and execute it twice (we only set up two id)

Here, the setup has been completed, and then execute the thread group, and you will see 2 different results

The two results of id are consistent with our two id of id.csv, and the parameterized values are assigned normally to meet the test expectations.

Multiple file formats can be supported in Csv data set config. Let's use a txt example to show how to create an id.txt file in the directory home directory, as follows:

In modify Csv data set config, change the file name to id.txt

Remember to clear the last record before execution. We also gave 2 id in id.txt, which will be executed twice.

Both methods are very easy to use and achieve the desired results. I do not know if you have learned, if there is not clear welcome to leave a message to me. If the article is helpful to you, please follow my official account and share and retweet, so that more friends can grow together.
