But I donnot know how to collect coverage at method level.（Because my ability is limited😭） could you tell me how to....I will be very thankful~

Hi @WuYiwen97,

GZoltar supports out-of-the-box three granularity levels: class, method, and line (default). To use a different granularity level you must configure the fault-localization report with a different granularity level.

For example:

• Supposing you are using the Ant example of the GZoltar Ant task you need to modify line #134 to method, or class.
• Supposing you are using the GZoltar CLI example you need to modify line #172 to method, or class.
• Supposing you are using the GZoltar Maven example you need to modify line #81 to method, or class.

In case you are using external scripts such the ones in the fault-localization repository you need to modify line #438 to method, or class. Please not that if you change #438 to method, or class you would also have to comment out or remove the sanity checks performed in lines 283 -- 533 in the job.sh script. (the job.sh script runs GZoltar on a single D4J bug).

-- Best, Jose

Just a note on this: on MacOS (maven version: 3.6.1, gzoltar: 1.7.2) I had to manually provide the flag -Dgzoltar.granularity=method, e.g. mvn gzoltar:fl-report -Dgzoltar.granularity=method. Providing the method value via the plugin configuration did not work.
