It's showing either percentage number `X% of N` or `---`. `X% of N` means that `X%` of `N` coverage points is covered so far, a coverage point generally refers to a basic block or a CFG edge (depends on compiler and instrumentation mode used during build). `---` indicates there is no coverage in that directory. Directory can be clicked and you get view on files and possible subdirectories. On each source code file there is again either `---` or coverage percentage. |
