+# go-junit-report
+
+Converts `go test` output to an xml report, suitable for applications that
+expect junit xml reports (e.g. [Jenkins](http://jenkins-ci.org)).
+
+[![Build Status][travis-badge]][travis-link]
+[![Report Card][report-badge]][report-link]
+
+## Installation
+
+Go version 1.1 or higher is required. Install or update using the `go get`
+command:
+
+```bash
+go get -u github.com/jstemmer/go-junit-report
+```
+
+## Contribution
+
+Create an Issue and discuss the fix or feature, then fork the package.
+Clone to github.com/jstemmer/go-junit-report.  This is necessary because go import uses this path.
+Fix or implement feature. Test and then commit change.
+Specify #Issue and describe change in the commit message.
+Create Pull Request. It can be merged by owner or administrator then.
+
+## Run Tests
+go test
+
+## Usage
+
+go-junit-report reads the `go test` verbose output from standard in and writes
+junit compatible XML to standard out.
+
+```bash
+go test -v 2>&1 | go-junit-report > report.xml
+```
+
+Note that it also can parse benchmark output with `-bench` flag:
+```bash
+go test -v -bench . -count 5 2>&1 | go-junit-report > report.xml
+ ```
