The MPLAB^® Code Coverage feature provides visibility as to what portions of your code are being executed. Run your test cases to completion for a visual display of coverage.

The MPLAB Code Coverage feature requires the following tools:

• An MPLAB XC C compiler (either Free or PRO) that supports code coverage output, starting with MPLAB XC8 v2.10, MPLAB XC16 v1.40, and MPLAB XC32 v2.30.
• The MPLAB Code Coverage (SW006026-COV) license that provides visibility as to what portions of your code are being executed.
• MPLAB X IDE v5.25 or later, which supports the display of code coverage data from an MPLAB XC C compiler with the MPLAB Code Coverage license.

Code coverage is displayed in the MPLAB X IDE as:

• Editor text highlighted by colors representing coverage:
  • green = executed
  • yellow = partially executed
  • red = not executed
• Program memory highlighted by colors representing coverage.
• ACode Coverage tab with a report displaying color percentages of code covered. This information may be written to an HTML report for later viewing.
