Jmeter-----Randomly generated mobile phone number 8 bit and go to heavy, to register mobile phone number of the pressure test

　　Requirements: 100,000 times the registration interface of the pressure test, mobile phone number has 126 beginning, the following 8 digits Unlimited

Foreword: In the test, we need to 100,000 times the registration interface, then the mobile phone number is required to complete the inconsistency, or mobile phone number will appear after the mobile phone number has been registered, in order to avoid this situation, we have to fill in the mobile phone number is usually 2 ways, 1, Randomly generated using the random function, 2, manually write 100 numbers in the Excel table, by adding a configuration component CSV Data set config to get. Obviously we will choose the first way of implementation is more convenient. Let's look at how to do this.

The first method:

　　Using the function helper directly, use the __random function to generate 8-bit numbers. Possible problems: The number of builds may appear duplicated

　　

　　

The second method:

　　Use timestamp + random number method to avoid duplication and generate 8-digit non-repeating numbers

1, add sampler BeanShell Sampler, and fill in the corresponding operation, the key part

//to avoid duplication of 8 digits after the phone number, use timestamp + random numberPhone=${__time (/100000,)} + ${__random (1,100000,)}; String a= string.valueof (phone);//turn the phone into a string because the phone number requires the type charVars.put ("Phone", a);//set string A to a variableVARs.Get("Phone");//Check the value of the phone in debug sampleLog.info ("8888888888888 hahaha:"+A);//Print view values in LogView

　　

　Here, the first half is to take a 10-bit timestamp, followed by a random number of 1 [1,100000], can be repeated, the larger the random range, the last generation of random number is not easy to repeat, when large concurrency, random numbers take quickly, so there is very low likelihood of repetition. So within the scope of the license, try to pull a large random number range.
${__time (,)} is the number that goes to the current millisecond time, 13 digits, and can be used to take a more accurate timestamp

2. Add the set of variables to the request

　　

3. Add "View results tree" to view the results of the operation, and add "Bebug Sampler" to view the value of the phone
