If this is the case, and the test run exercises all the code blocks in the line, it is counted as one line. A long block of calculation would count as a single block even if it occupies many lines.Ī line of code can contain more than one code block. Some users prefer a count of lines because the percentages correspond more closely to the size of the fragments that you see in the source code. You can also have the results displayed in terms of lines by choosing Add/Remove Columns in the table header. The number of times the block is used has no effect on the result. If the program's control flow passes through a block during a test run, that block is counted as covered. A block is a piece of code with exactly one entry and exit point. Report in blocks or linesĬode coverage is counted in blocks.

Coverage results and code coloring are not automatically updated after you modify your code or when you run tests. If you don't get the results you expect, see Troubleshoot code coverage.ĭon't forget to run code coverage again after updating your code. If you're working with unmanaged (native) code, use a debug build.
