Run same test case in parallel for no of times. (multi-threading support)

[aghorpade]

I would like to run same test case for API testing in parallel. e.g. call GET api around 10 times in parallel and see response so I can check if any issue with my code in case of multi-threaded env.

Hi,
Thanks for the question.
This framework leverages the power of JUnit. That means all the advantages and power of JUnit is already available to the you(as users). Also you have advantages of overriding the ZerocodeRunners for your own customization e.g. setting up mocks, doing specific tasks to put the target system in a desirable state etc.

Parallel running is easy and simple, you can run parallely-

1. Each test wise
2. Class wise

In both ways you have choices of running the test cases in parallel.

• Test wise-

<configuration>
    <parallel>methods</parallel>
    <threadCount>2</threadCount>
</configuration>

• Class wise

<configuration>
      <parallel>classes</parallel>
      <threadCount>2</threadCount>
</configuration>

Suggestion-
Please start with thread count as 2, then increase to 3, then 4, 5... 10 etc to make sure your system is able to spawn so many threads.

Usage-
Look for artefact id <artifactId>maven-surefire-plugin</artifactId> in your POM or module POM.
The configure it below way.

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>${surefire-version}</version>
        <configuration>
            <parallel>classes</parallel>
            <threadCount>2</threadCount>
        </configuration>
    </plugin>

Hope it helps!

If your question is short, concise and you lookin for quick answers, you can even put into the gitter too.

Zerocode is intuitive for users once you start using it!

e.g.

@LoadWith("your_load_config.properties")
@TestMapping(testClass = AnyTestEndPoint.class, testMethod = "anyTestMethod")
@RunWith(ZeroCodeLoadRunner.class)
public class LoadTest {
}
