How to Add Debug Data to the Result Browser

To aid in error analysis, XTC provides a feature that allows you to add your custom debug data to the result browser: the session’s value log is a storage for session-specific test parameters and result data. Any value you add to this log will later be available in the result browser.

Value Log in the Result Browser

This feature is primarily intended to aid in error analysis. The data in the result browser may help you to reconstruct and rerun a failed test case iteration without having to dig into log files, etc. Simply add any value of special interest and it will be available in the result browser. This is especially useful if your test case uses random or randomly chosen test parameters.

To address the problem with random test parameters, XLT adopts this feature to make the seed value of XltRandom - used for the current test iteration/session - available in the result browser. To rerun a test case with this seed value (i.e. with the “same randomness”), copy the seed value from the result browser, add the following line to your dev.properties file, and re-execute the test as usual from your favorite IDE:

com.xceptance.xlt.random.initValue = <copied seed value>

You may also add your own arbitrary values to the session’s value log. See below on how to access the value log and add values to it:

Map<String, Object> valueLog = Session.getCurrent().getValueLog();  
valueLog.put(“account.email”, randomEmail);  
valueLog.put(“cart.total”, currentCartTotal);

Your data will be stored as simple name/value pairs. Even though the log accepts any Object as value, it still needs to be converted to a string for proper display in the result browser, so make sure that your value classes provide a sensible toString() method.
