go-junit-report

go-junit-report is a tool that converts go test output to a JUnit compatible XML report, suitable for use with applications such as Jenkins.

Build status Go Reference Go Report Card

Install from package (recommended)

Pre-built packages for Windows, macOS and Linux are found on the Releases page.

Install from source

Download and install the latest stable version from source by running:

go install github.com/jstemmer/go-junit-report/v2@latest

Usage

By default, go-junit-report reads go test -v output generated by the standard library testing package from stdin and writes a JUnit XML report to stdout.

Go build and runtime errors are also supported, but this requires that stderr is redirected to go-junit-report as well.

Typical use looks like this:

go test -v 2>&1 ./... | go-junit-report -set-exit-code > report.xml

More examples

JSON produced by go test -json is supported by the gojson parser. Note that stderr still needs to be redirected to go-junit-report in order for build errors to be detected. For example:

go test -json 2>&1 | go-junit-report -parser gojson > report.xml

Go benchmark output is also supported. The following example runs benchmarks for the package in the current directory and uses the -out flag to write the output to a file called report.xml.

go test -v -bench . -count 5 2>&1 | go-junit-report -out report.xml

The -iocopy flag copies stdin directly to stdout, which is helpful if you want to see what was sent to go-junit-report. The following example reads test input from a file called tests.txt, copies the input to stdout and writes the output to a file called report.xml.

go-junit-report -in tests.txt -iocopy -out report.xml

Flags

Run go-junit-report -help for a list of all supported flags.

Flag Description
-in file read go test log from file
-iocopy copy input to stdout; can only be used in conjunction with -out
-no-xml-header do not print xml header
-out file write XML report to file
-package-name name specify a default package name to use if output does not contain a package name
-parser parser specify the parser to use, available parsers are: gotest (default), gojson
-p key=value add property to generated report; properties should be specified as key=value
-set-exit-code set exit code to 1 if tests failed
-subtest-mode set subtest mode, modes are: ignore-parent-results, exclude-parents
-version print version and exit

Go packages

The test output parser and JUnit XML report generator are also available as Go packages. This can be helpful if you want to use the go test output parser or create your own custom JUnit reports for example. See the package documentation on pkg.go.dev for more information:

Changelog

v2.0.0

  • Support for parsing go test -json output.
  • Distinguish between build/runtime errors and test failures.
  • JUnit report now includes output for all tests and benchmarks, and global output that doesn't belong to any test.

  • Add support for reading skipped/failed benchmarks.
  • Add -subtest-mode flag to exclude or ignore results of subtest parent tests.
  • Add -in and -out flags for specifying input and output files respectively.
  • Add -iocopy flag to copy stdin directly to stdout.
  • Add -prop flags to set key/value properties in generated report.
  • Add -parser flag to switch between regular go test (default) and go test -json parsing.
  • Output in JUnit XML is written in <![CDATA[]]> tags for improved readability.
  • Add hostname, timestamp and id attributes to JUnit XML.
  • Improve accuracy of benchmark time calculation and update formatting in report.
  • No longer strip leading whitespace from test output.
  • The formatter and parser packages have been replaced with junit and parser/gotest packages respectively.
