The display of code coverage in SIMATIC AX Code can be toggled using the symbol in the status bar at the bottom. Click on the circle with the Watch label next to it.
Note
The result of the coverage is always rounded down. The displayed coverage is the coverage for the selected ST file and not the coverage for the whole project. The coverage result also only displays the coverage for the last test execution and does not take previous test executions into account, even if different tests where executed.
Note
The visualization of code coverage in SIMATIC AX Code is brought to you by Ryan Luker.
