Hello all,
Today I am going to post a quick snippet that I used recently and it quite made me spent a lot of time just because I didn’t read the Jmeter documentation in the first place 😅
In the pom.xml you will need to set some jmeter configurations:
<?xml...
<project...
<properties>
<jsonValue>[{"name": "Rafa", "age": 20},{"name": "Robin", "age": 5}]</jsonValue>
</properties>
...
<build>
<plugins>
<plugin>
</configuration>
...
<propertiesUser>
<jsonValue>${jsonValue}</jsonValue>
</propertiesUser>
</configuration>
</plugin>
How it should look like:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<configuration>
<!--

-->
<source>${project.build.directory}/results/*</source>
</configuration>

</project>
On the Test Plan configuration you will need to set the parameters getting it from the pom.xml:
- The default value for this parameter is:
[{"name": "Rafa", "age": 20},{"name": "Robin", "age": 5}] - It is optional to set a default value in case it is not sent.
- Note that we will need to escape the commas when adding the value to the jmeter script:
${__P(jsonValue,[{"name": "Rafa"\, "age": 20}\,{"name": "Robin"\, "age": 5}])}
Now you can run your jmeter tests passing a json code to the maven command line and if you don’t pass this parameter, then Jmeter is going to use the default one.
