How to make Intellij Idea Coverage display full colored lines?

Question

In Eclipse, most of the coverage plugins, display covered/partially covered/uncovered lines with different colors (i.e. the whole line painted with a color)

In IntelliJ Idea, I couldn't find a way yet to paint the whole line with a descriptive color, only a small, almost imperceptible mark is added on the left hand side, making the visualization of partially covered / uncovered lines really difficult.

Any idea?

Answer 1

I found the solution to this problem here but I thought it would be better to create a specific, well-phrased question so that people having exactly the same problem as me can find it better in Google / StackOverflow.

In a nutshell, through Editor -> Colors & Fonts -> General (or, at least from IntelliJ 2017.3 onwards, Editor -> Colors Scheme -> General)

you can customize the Colors & Fonts used for covered/partially covered/uncovered lines, modifying the background of the following entries:

• Full line coverage
• Partial line coverage
• Uncovered line

For example, I wanted to use the same default colors already provided but not only on the margin but on the whole line (similar to how Eclipse does it), so I disabled "Foreground" and enabled "Background". Voilà!

Answer 2

I think the UI has been updated the the way to get to this option has changed. While it is already mentioned by others, I'd like to elaborate with a more detailed image to make it easier to see.

Intellij > Preferences > Editor > Color Scheme > General > Line Coverage > 

There you will have three options.

• Full
• Partial
• Uncovered

Here is the menu option:
