I am using DBT (data build tool) as an ETL tool for data analytics . 
The command 
dbt test
Resuts in the test cases being pass/fail on the output terminal but need to export this result into JSON/HTML/XML format for reporting.
Any help in this regard ?
If you are executing this on an UNIX shell like Mac or Linux, you can try with tee like this.
dbt run | tee -a your_log_file.txt
This will create and append there on the a log file of your choosing for whatever results of the dbt run command.
Can the results of dbt test be converted to report
