Viewing Code Coverage Results

Viewing code coverage helps you detect pieces of your source code that are not affected by simulation.

To view code coverage results

  1. Do one of the following:
  2. View coverage results:
  3. Open in the editor the files you want to explore.
  4. Use the color indicators in the left gutter to detect the uncovered lines of code.
  5. To find out how many times a line has been hit, click the line in the gutter area.

    The pop-up window that opens shows the statistic for the line at caret. For lines with conditions, the pop-up window also provides statistic on the number of true and false hits.

    Use the following toolbar buttons:

    • arrowUp arrowDown: jump to the next/previous groups of covered or uncovered lines.
    • junitIcon: view JUnit tests that cover the line at caret.

      The test that covers the line at caret, is shown in a pop-up window:

    • show-byte-code: show byte code of the current class in a pop-up window:
      • This button is only available, when Byte Code Viewer plugin that comes bundled with the product, is enabled.
      • When pinned, this pop-up window converts into the Byte Code Viewer.
    • settingsCoverage: open the General page of the Colors and Fonts settings, with the line Full line coverage highlighted.
    • close.png: hide coverage information.
  6. Create missing tests, as described in the section Creating Tests.
