Gocov HTML export

This is a simple helper tool for generating HTML output from axw/gocov.

gocov-html has support for themes, you might want to have a look at the screenshots.

Installation

Binaries for most amd64 systems are built for every release. Please just grab a binary version of the latest release.

You can also build it from source. In this case, a working Go 1.11+ compiler is required:

$ go install github.com/matm/gocov-html/cmd/gocov-html@latest

A Dockerfile is also provided.

Usage

Usage of gocov-html:
  -cmax uint
        only show functions whose coverage is less than cmax (default 100)
  -cmin uint
        only show functions whose coverage is more than cmin
  -d    output CSS of default theme
  -lt
        list available themes
  -r    put lower coverage functions on top
  -s string
        path to custom CSS file
  -t string
        theme to use for rendering (default "golang")
  -v    show program version

Examples

Generate code coverage for the strings package then generate an HTML report:

$ gocov test strings | gocov-html > strings.html
ok      strings 0.700s  coverage: 98.1% of statements

Merge several coverage stats for different packages into a single report:

$ gocov test fmt math io | gocov-html > report.html
ok      fmt     0.045s  coverage: 95.2% of statements
ok      math    0.006s  coverage: 83.6% of statements
ok      io      0.024s  coverage: 88.2% of statements

In this case, the generated report will have an overview section with stats per package along with the global coverage percentage. This section may be rendered depending on the theme used. The golang (default) theme displays it.

List all available themes:

$ gocov-html -lt
golang     -- original golang theme (default)
kit        -- AdminKit theme

Generate a report using a specific theme with -t:

$ gocov test io | gocov-html -t kit > io.html

Only show functions whose code coverage is lower than 90% for the strings package:

$ gocov test strings|./gocov-html -cmax 90 > strings.html

In this example, only 5 matches are added to the report.
