I'm assuming you've gone through Configuring Bromine for selenium Core

Creating and uploading the testsuite

Core tests are linked to Bromine testcases through their name. A test named 'test_example' will be linked to the testcase 'test_example'
This is critical if you want to use your core tests for Automatic requirement analysis.

1. Record a test. Save it as 'test_example.html'
2. Upload the test to your site
3. Add the test to your suite
4. Open Bromine
5. Navigate to 'Test Lab' --> 'Testcases'
6. Create a testcase and name it test_example. Fill in the steps or some jibberish

Running the testsuite

1. Click the 'test lab' tab
2. Click 'Testrunner core'
3. Choose environment (site to be tested)
4. Choose the current browser you are using
5. Choose the current OS you are running
6. Choose the testsuite you'd like to run
7. Choose an interval if you'd like
8. Click 'run test'

The testsuite should now be bussying along on its own in a new tab. When it's done you should get some sort of debug text saying how many commands were received and how many were inserted and so on. Don't mind if the numbers are odd.

Now go take a look at your results in the 'Test Result Manager' --> 'Raw data'
