Data related to the single component consists of three files:
- component_name_reports - defect reports from Bugzilla
- component_name_backlog - defect reports converted into weekly defect backlog
- component_name_samples - set of week numbers from defect backlog for further predictions
These files are located in Data/project_name/component_name folder.
Defect reports were converted into weekly defect backlog. Every week in the backlog includes the following metrics:
-
backlog_all - the number of all defects in the backlog
-
inflow_all - the number of defects that were reported in corresponding week
-
outflow_all - the number of defects that were resolved in the corresponding week
-
backlog_normal - the number of defects labeled as normal in the backlog
-
inflow_normal - the number of defects labeled as normal that were reported in corresponding week
-
outflow_normal - the number of defects labeled as normal that were resolved in the corresponding week
-
backlog_major - the number of labeled as major defects in the backlog
-
inflow_major - the number of defects labeled as major that were reported in corresponding week
-
outflow_major - the number of defects labeled as major that were resolved in the corresponding week
For each defect backlog one week was drawn for each month. Week numbers which were drawn are saved in the file component_name_samples. The numbers refers to the week number in the corresponding defect backlog.
