To get fully combined results, use the same build of the code, changing only the test data. If you merge coverage data from different versions of the code, the results are shown separately, but they aren't combined. Use Export Code Coverage Results to save the results of a merge operation. If you want to combine exported results, you must import them first. You can choose any combination of recent runs or imported results. Use Merge Code Coverage Results to do this. Now you merge the results from the two test runs, and the report and coverage coloring view shows that 100% of the function was covered. When you run the test a second time with the input '-2', you see in the coverage coloring view that the other 50% of the function is covered. Therefore, you might want to combine the results from different test runs.įor example, suppose that when you run a test with input '2', you find that 50% of a particular function is covered. In some situations, different blocks in your code will be used depending on the test data. If they have the same version of the source code, they can see coverage coloring. To send results to someone else, send either a. coveragexml file, which you could process with other tools or send easily in mail. To make results readable as text, choose Export Code Coverage Results. The coverage coloring might be incorrect if the source code has changed since the. To view results from a previous session, choose Import Code Coverage Results, navigate to the TestResults folder in your solution, and import a. The menu shows a temporary list that is cleared when you open a new solution. To view a previous set of results, select it from the drop-down menu.

You can merge the results of several runs, for example from runs that use different test data. The Code Coverage Results window can also be used to view previous results, or results obtained on other computers. The results will vary if you change your test data, or if you run only some of your tests each time. The Code Coverage Results window usually shows the result of the most recent run. If some but not all code blocks in the line are exercised, it is counted as a partial line. If this is the case, and the test run exercises all the code blocks in the line, it is counted as one line. A line of code can contain more than one code block.
