Get code coverage when integration testing performed on application.

[nag....@gmail.com]

Hi,
We have a desktop application where we will not be able to write junints for complete application due to the architecture ( pretty old application). With the limited Junints we could see only 30% code coverage. Our idea is to know code coverage by running the application. It means we will perform some manual testing and at the end of the testing we would like to know the code coverage. This way, we will try to get the coverage details without the Junints. I am little knew to this area. Can anyone help me please? Additional information is that we are using ant to make the build. We are not using maven.

Thanks
Nagaraju

Hi Nagaraju,

the JaCoCo agent can collect execution data for any Java application, also manually tested desktop applications. All you need to do is to configure the JaCoCo agent for the JVM running your application. See documentation: https://www.jacoco.org/jacoco/trunk/doc/agent.html

When the application terminates a *.exec files is written. You can use Ant to create a report from it as you do it today.

Regards,

Hi, 

    I tried the following command but it did not return anything related to coverage. Can you please suggest if I am doing anything wrong?

java -jar test.jar -javaagent:C:/jacoco-0.8.5/lib/jacocoagent.jar=output=file

Thanks

Hi, 

    I am able to generate the report. Thanks. 

Issue was the order of javaagent in the command.
