JUnit test failing with NPE while using Variables objectValue method to store large value in execution context

 execution.setVariable("variable", Variables.serializedObjectValue(getMessage(messageString)).create());

tried differently

execution.setVariable("variable", Variables.objectValue(getMessage(messageString()))
                .serializationDataFormat(Variables.SerializationDataFormats.JAVA).create());

as far as I can see there are 2 issues:

  1. not able to mock the Variables class
  2. not able to workaround the mocking of Variable class

error stack trace for the location of invocation:

Caused by: java.lang.NullPointerException
	at org.camunda.bpm.engine.impl.core.variable.VariableUtil.checkJavaSerialization(VariableUtil.java:47)
	at org.camunda.bpm.engine.impl.core.variable.scope.AbstractVariableScope.setVariableLocal(AbstractVariableScope.java:308)
	at org.camunda.bpm.engine.impl.core.variable.scope.AbstractVariableScope.setVariable(AbstractVariableScope.java:303)
	at org.camunda.bpm.engine.impl.core.variable.scope.AbstractVariableScope.setVariable(AbstractVariableScope.java:284)

how can I mock the Variables object in my Junit or can I have a workaround if not possible to mock the variable class

solution:

 CommandContext mockedCmdContext = mock(CommandContext.class);
        ProcessEngineConfigurationImpl mockedConfiguration = mock(ProcessEngineConfigurationImpl.class);
        Context.setCommandContext(mockedCmdContext);
        Context.setProcessEngineConfiguration(mockedConfiguration);
