How to format JUnit console output?

Question

Is it possible to format the JUnit output on the console in order to have a customed output? For example the standard JUnit output from my actual tests is:

junits:
[junit] Running com.myapp.tests.dao.Test_1
[junit] Testsuite: com.myapp.tests.dao.Test_1
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 10,016 sec
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 10,016 sec
[junit]
[junit] Testcase: insert took 3,984 sec
[junit] Running com.myapp.tests.dao.Test_2
[junit] Testsuite: com.myapp.tests.dao.Test_2
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 13,35 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 13,35 sec
[junit]
[junit] Testcase: load took 3,239 sec
[junit] Testcase: insert took 2,21 sec
[junit] Running com.myapp.tests.dao.Test_3
[junit] Testsuite: com.myapp.tests.dao.Test_3
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 12,786 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 12,786 sec
[junit]
[junit] Testcase: insert took 2,607 sec
[junit] Testcase: update took 2,338 sec
[junit] Running com.myapp.tests.dao.Test_4
[junit] Testsuite: com.myapp.tests.dao.Test_4
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 14,803 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 14,803 sec
[junit]
[junit] Testcase: getAll took 4,73 sec
[junit] Testcase: insert took 2,289 sec

I would like to better highlight each JUnit class. At least by adding some new lines in order to generate a similar output:

junits:
[junit] Running com.myapp.tests.dao.Test_1
[junit] Testsuite: com.myapp.tests.dao.Test_1
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 10,016 sec
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 10,016 sec
[junit]
[junit] Testcase: insert took 3,984 sec
[junit]
[junit]
[junit]
[junit] Running com.myapp.tests.dao.Test_2
[junit] Testsuite: com.myapp.tests.dao.Test_2
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 13,35 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 13,35 sec
[junit]
[junit] Testcase: load took 3,239 sec
[junit] Testcase: insert took 2,21 sec
[junit]
[junit]
[junit]
[junit] Running com.myapp.tests.dao.Test_3
[junit] Testsuite: com.myapp.tests.dao.Test_3
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 12,786 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 12,786 sec
[junit]
[junit] Testcase: insert took 2,607 sec
[junit] Testcase: update took 2,338 sec
[junit]
[junit]
[junit]
[junit] Running com.myapp.tests.dao.Test_4
[junit] Testsuite: com.myapp.tests.dao.Test_4
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 14,803 sec
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 14,803 sec
[junit]
[junit] Testcase: getAll took 4,73 sec
[junit] Testcase: insert took 2,289 sec

I am not aware of a way to format the console output of JUnit. However you can have JUnit produce reports in various formats, for example HTML, or XML.

Also, there is a whole lot of tools out there to process the results and present them to you in a useful manner. The Eclipse IDE for Java Developers, for example, comes packed with functions to run or debug unit tests and view the results in a tree view.

You can also use a Continous Integration System such as Jenkins to run your tests. It produces an interactive HTML report of your test results if you configure it to do so.

You're right, it will be better to process the results. As a Jenkins server is used, I will look for a documentation on how to configure it. – Sabbane Feb 04 '15 at 12:18

If you want full control, you can implement your own test runner quite easily.

Derive from RunListener – a class that handles testStarted, testFinished, testFailure etc – and then pass an instance of it as via addListener() to the JUnitCore.

I did this once to write what I then considered a fancy console log in just a few pages of code. It is not hard but given that you mostly want to insert a few additional line breaks, it might be a bit overkill.
