    152  * In order to run tests inside the @jhbuild@ shell, these two environment variables must be set:
    153 {{{
    154 #!sh
    155 $ export TEST_RUNNER_TEST_PLUGIN_PATH=$WEBKIT_HOME/WebKitBuild/Release/Libraries/.libs/
    156 $ export TEST_RUNNER_INJECTED_BUNDLE_FILENAME=$WEBKIT_HOME/WebKitBuild/Release/Libraries/libTestRunnerInjectedBundle.la
    157 }}}
    158 
    159 
    160 == Debugging issues ==
    161 
    162  * Some times when running the WebKitTestRunner (WK2) you can see linking errors like the following one:
    163 {{{
    164 #!sh
    165 
    166 (lt-WebKitWebProcess:3392): WARNING **: Error loading the injected bundle (/home/javi/devel/WebKit/webkit.git/WebKitBuild/Debug/Libraries/libTestRunnerInjectedBundle.la): /home/javi/devel/WebKit/webkit.git/WebKitBuild/Debug/Libraries/.libs/libTestRunnerInjectedBundle.so: undefined symbol: _ZTVN7leveldb10ComparatorE
    167 }}}
    168    * One possible cause of such errors are missing symbols in the '''Source/autotools/symbols.filter'''. These symbols are automatically exposed in the by the '''libWebCoreInternals''' library via tags. Such library expose some symbols for testing purposes, just like the WTR application does.
    169    * The symbols.filter should be updated by a fresh checkout, but if that's not the case, it's possible to workaround the issue by manually adding the missing symbols to the file.
     150Once the MiniBrowser opens showing the results, look for the stderr hyper-text link. The GStreamer logs will be in that file.
