I am doing a project which will build an ETL-grader. The ETL-grader is used to automatically evaluate the ETL script which is submitted by students. Now, I am trying to write an Eunit test for the ETL script to test if the script is correct. I have already read the relevant examples on the Epsilon website and I find that the Eunit test is easy to run on eclipse. However, the ETL-grader need to be implemented on Linux, which means I need to use command line to execute the Eunit test. I do not know what is need to run the Eunit test on linux. I find that in the example the author use ant task to execute the euint test. Therefore, I am also trying to use ant task to solve this problem, however, there is an error appear which shows an error which is
"BUILD FAILED
/home/jian/Desktop/org.eclipse.epsilon.eunit.examples.etl/build.xml:34: Problem: failed to create task or type epsilon.emf.register
Cause: The name is undefined.".
I think it may mean I need to import or install epsilon.emf. However, I do not know how to do this.
Do I do the correct thing? Could you please tell me how to fix this problem?
Or could you tell me how to run epsilon scripts on Linux?

Hi,

Does this help? https://www.eclipse.org/epsilon/doc/articles/running-epsilon-ant-tasks-from-command-line/ (you may have to replace 2.3.0-SNAPSHOT with 2.3.0 in some of the examples).

Best,
Dimitris

Dear Dimitris,
I want to output how many mistakes and what are those mistakes in the ETL script. Does the EUnit have functions which are similar with org.junit.runner and org.junit.runner.notification?
Best wishes,
Jian
