What is a bug trend report in software testing?

The Bug Trends (or Defect Trends, Bug Dynamics) report in Software Testing calculates total number of bugs that the QA team has opened and closed over time. The reports are important for management to understand the overall trend at which the bugs are processed.

How to create a bug chart?

Just like the other items, the chart needs a data provider. In this case, you should load the Bugs Chart view for the settings table. Then, just drag the chart so it is a child of the data provider and adjust its settings. You need to use the label column as “name” and the data columns as “value”.

Why is a bug report important?

So +1 to this answer, even though bug taxonomy is what the question was after.
