[JAVA] Load test with JMeter

I summarized it because there was no memorandum of addiction and an article that explained from top to bottom unexpectedly.

Purpose

Do a load test with JMeter. 10 accesses per second. Target https://hogehoge.jp/abc With basic authentication nuxt.js, API communication backend Laravel JMeter is done on Mac.

JMeter installation

Install JMeter anyway. Do it with brew. If you don't have brew, install brew.

To use JMeter, you need the main body and Java.

brew install jmeter
brew tap homebrew/cask-versions
brew cask install java

At the time of writing this, java version 14 was installed, but it worked normally.

Run JMeter

Run from the console.

jmeter

This will open the GUI tool. Use this screen to create a test plan (test content).

Localizing into Japanese

To make it Japanese, select the following from the menu. Options > ChooseLanguage > Japanese

Creating a test plan

Left column setting

Right-click on "Test Plan" in the left column Add> Threads (Users)> Thread groups Select to create a thread group.

Next, right-click on the "thread group" created above. Add> Sampler> HTTP Request Add> Listener> Statistical Report Add> Listener> View Results in Table Add> Listener> Save Response to File Add> Listener> Graph display Select to create each.

• The results are not shown in the table. It is not necessary to have the bottom three, but it is better if the results are easy to see.

Then it looks like this.

Thread group settings

Decide how many times to run the test every few seconds. Number of threads: 10 Ramp-UP period (seconds): 1 Number of loops: 1

To set. The above means that 10 requests will be executed in 1 second.

HTTP request settings

Select the HTTP request in the left column and enter the information.

If you have basic authentication

Right click on HTTP request Add> Configuration Element> HTTP Authentication Manager Select and create.

Save

Select ** TestPlan and press ** Ctrl + s to save. After this, this file will be used, so save it in a convenient location.

test

I will test if it works for the time being. Press the green △ at the top of the GUI to execute. After execution, select "Show results in table" and if Status is green, it is successful.

JMeter implementation

Implementation is done with CUI instead of GUI. Execute with the following command.

jmeter -n -t ~/src/jmeter/test_plan.jmx -l ~/src/jmeter/log.jtl
#For the path, set the location of the saved file. Please specify an appropriate location for the log.

Check the log

The contents of the log are like this.

cat ~/src/jmeter/log.jtl

Gununu ... This is due to the limit on the number of requests for laravel. Let's adjust the number of simultaneous accesses by referring to the articles around here. https://qiita.com/HorikawaTokiya/items/c04e410e4ed76d3dddc2

That's it. Chan-chan.
