I use CTest fixtures.  
In my `FIXTURES_SETUP` I call a bash script, wich is starting a service in the background via:

```
"$@" > ${SERVICE_LOG_FILE} 2>&1 &

RESULT=$?

```

You see how I store the log output via a text file

Then in the `FIXTURES_CLEANUP` step I print the output of the logfile:

`$(cat ${SERVICE_LOG_FILE})`

However, even when the logfile contains text like this:  
` “[2020-09-18′ ’15:07:05.978]’ ‘[error]’ ‘FAILED!'”`

Ctest does not mark my FIXTURES\_CLEANUP test a failed.  
What is the problem?

Note that this _executes_ the output of the file. Are you sure you didn’t mean just `cat ${SERVICE_LOG_FILE}`?

If you want the test to be marked as failed based on the test output, then you need to set the test property `FAIL_REGULAR_EXPRESSION` to an appropriate value that will match the output according to your criteria.
