Code Coverage Window
Specifies the extent to which the application code is covered by tests. You use the Code Coverage window to track code coverage after you have run one or more test suites in the CAL Test Tool window. You can run both pages from the development environment, or from the Microsoft Dynamics NAV Windows client or the Microsoft Dynamics NAV Web client.
In the Code Coverage window, you can start, refresh, and stop the code coverage recorder.
Important
Code coverage is recorded globally for all sessions, so make sure that you run the tool in a controlled environment so you do not have any activity from unaccounted sessions.
Monitoring Code Coverage
Code coverage is the means of being able to track which part of the application code has been exercised during test activity. In Microsoft Dynamics NAV, code coverage is recorded by C/AL code line and specifies if a code line was exercised by test and the number of times the line of code was recorded.
To start monitoring code coverage, choose Start. This starts the code coverage engine, and code coverage is captured. However, you will not be able to see any updated information until you choose Refresh or Stop. The information contains coverage of objects, triggers and functions, and individual lines of code or empty lines as determined by the column Line Type. Only lines of type Code can have coverage. Lines of type Trigger/Function show the average coverage of all code lines in the trigger or function. Lines of type Object show the average coverage of all code lines inside the object. The following table illustrates the result of a code coverage run:
| Code | Coverage % | Line Type |
|---|---|---|
Table Currency (4) |
20,00 |
Object |
OnModify() |
0,00 |
Trigger/Function |
OnDelete() |
0,00 |
Trigger/Function |
OnRename() |
0,00 |
Trigger/Function |
InitRoundingPrecision() |
81,82 |
Trigger/Function |
In this example, the activity exercised 20% of the Currency table, including 81,82% of the InitRoundingPrecision function.You can then expand the section for InitRoundingPrecision to investigate the code coverage for each line of code in this function.
Only objects that are touched by the activity are recorded. This means that if an object is not shown in this window, the coverage of the object is implied to be zero. If you want to force the code coverage recorder to include specific objects even if they are not covered, choose the Load objects action, and then specify the relevant objects. This forces the code coverage engine to load these objects and provide information on even when no lines are covered.
