You won't get test case line info if it's the last line of
execution that causes the timetrap timeout. Because of tail call
elimination the {Suite,Testcase,Line} info is not saved on stack
unless there's a trailing expression. I.e.<br>
<br>
tc(_) -> func_that_may_not_return().<br>
<br>
will not generate test case line info if it fails, but<br>
<br>
tc(_) -> func_that_may_not_return(), ok.<br>
<br>
will.<br>
<br>
That said, Common Test removes internal common_test and
test_server elements from the stack before printing the stack
trace to the log. This operation is too agressive and removes all
elements if no {Suite,Testcase,Line} tuple is found "to sync
with". Knowing it must be the last call in the test case causing
the timeout and knowing which internal function executed the test
case, I should be able to print relevant stack info to the log
even when a test case tuple is not present due to tail call
elimination. Fix is coming asap...<br>

look inside the HTML logs that Common Test generates? They
usually contain the complete error and stacktrace, while the
console only gets partials.

Dear list,<br>
When running CT I have a test where I get:<br>
<br>
- - - - - - - - - - - - - - - - - - - - - - - - - -<br>
Error detected: {'EXIT',{badmatch,{...}}}<br>
- - - - - - - - - - - - - - - - - - - - - - - - - -<br>
<br>
No additional information. My application logs do not
show any errors.<br>
<br>
Weirdly enough, if I put a timer:sleep(10) somewhere
in my code, this<br>
error does not show up anymore.<br>
<br>
Thing is: how can I get CT to tell me the module /
line where this error<br>
happens?<br>
<br>
Thank you,<br>
r.<br>
