Introduction on how to run performance tests with JMETER.
- Check you have JAVA installed:
java -version
-
Make sure the
JAVA_HOMEenvironment variable is set. -
Download JMeter: https://jmeter.apache.org/download_jmeter.cgi
-
Install JMeter:
- Unzip the zip/tar file into the directory where you want JMeter to be installed.
- Another option is to use Homebrew:
brew install jmeter
-
Start JMeter:
- Go to the
/binfolder and run thejmeter.bat(for Windows) or./jmeter(orsh jmeter.sh) (for Unix) file. - More details in the Apache website: https://jmeter.apache.org/usermanual/get-started.html#running
- Go to the
Contains a series of steps that JMeter will execute when run: Thread Groups, Logic controllers, listeners, timers, assertions, configuration elements, etc.
Place to keep elements temporarily, but they will not be saved.
We will simulate virtual users in a performance test.
Here we add the requests we can send to the server being tested (i.e HTTP FTP, etc)
We use them to gather info, save, view and analyze the performance test results in tabular or graphical form.
- View Results in Table
- It saves results in a table format.
- This visualizer creates a row for every sample result (or user request).
- It uses a lot of memory and CPU, so it's not suggested to be used for Load tests.
- Displays the sampler response header and response body.
| Column | Centered |
|---|---|
| Sample Time (ms) | the response time of the reques in miliseconds |
| Status | by default: green means the test passed, red means it failed (if we have assertions the status will depend on them) |
| Bytes | quantity of data in the sample response returned from the server (the size of the response). |
| Sent Bytes/sec | bytes virtual user(s) sent per second (request throughput) |
| Latency | the time to the first byte is returned, so the time it takes for a request to be sent and a response to be received (to acquire a connection) |
| Connect Time (ms) | time to establish connection |
