TestRunner.runner.TestRunner>> OutOfMemory Java heap space

OutOfMemory Errors 

Error Description:

The Java Virtual Machine (JVM) serves as a platform-independent execution environment for web applications written in Java. However, during test execution, the JVM runs out of memory while handling a large volume of data, resulting in reports not being generated. The following error message is displayed:

TestRunner.runner.TestRunner >> OutOfMemory Java heap space

Error Context:
This error occurs when JVM runs out of memory. This issue can arise due to either running a large number of test cases or when report size increases. 

Resolution:  
To address this, run the following commands for maven:
            To execute all the test cases : mvn test -DargLine="-Xmx512m"
            To execute a specific test case : mvn test -Dcucumber.filter.tags="@test002" -DargLine="-Xmx512m"    
 Resolution:  
To address this, run the following command to start the apache server:
java -Xmx512M -jar algoqa_springboot_api.jar 
In this preceding command, 512 mb of heap space will allocated to java server. You can increase or decrease the heap space according to requirement.
