gotestsum

gotestsum runs tests, prints friendly test output and a summary of the test run. Requires Go 1.10+.

Install

Download a binary from releases, or get the source with go get gotest.tools/gotestsum (you may need to run dep ensure).

Demo

Docs

gotestsum works by running go test --json ./... and reading the JSON output.

• Format
• Summary
• JUnit XML
• JSON file
• Setting go test flags and using custom commands

Format

Set a format with the --format flag or the GOTESTSUM_FORMAT environment variable.

gotestsum --format short-verbose

Supported formats:

• dots - output one character per test.
• short (default) - output a line for each test package.
• standard-quiet - the default go test format.
• short-verbose - output a line for each test and package.
• standard-verbose - the standard go test -v format.

Have a suggestion for some other format? Please open an issue!

Summary

A summary of the test run is printed after the test output.

DONE 101 tests[, 3 skipped][, 2 failures][, 1 error] in 0.103s

The summary includes:

• A count of: tests run, tests skipped, tests failed, and package build errors.
• Elapsed time including time to build.
• Test output of all failed and skipped tests, and any package build errors.

To disable parts of the summary use --no-summary section.

Example: hide skipped tests in the summary

gotestsum --no-summary=skipped

Example: hide failed and skipped

gotestsum --no-summary=skipped,failed

Example: hide output in the summary, only print names of failed and skipped tests and errors

gotestsum --no-summary=output

JUnit XML

When the --junitfile flag or GOTESTSUM_JUNITFILE environment variable are set to a file path gotestsum will write a test report, in JUnit XML format, to the file. This file can be used to integrate with CI systems.

gotestsum --junitfile unit-tests.xml

JSON file output

When the --jsonfile flag or GOTESTSUM_JSONFILE environment variable are set to a file path gotestsum will write a line-delimited JSON file with all the test2json output that was written by go test --json. This file can be used to compare test runs, or find flaky tests.

gotestsum --jsonfile test-output.log

Custom go test command

By default gotestsum runs tests using the command go test --json ./.... You can change the command with positional arguments after a --. You can change just the test directory value (which defaults to ./...) by setting the TEST_DIRECTORY environment variable.

You can use --debug to echo the command before it is run.

Example: set build tags

gotestsum -- -tags=integration ./...

Example: run tests in a single package

gotestsum -- ./io/http

Example: enable coverage

gotestsum -- -coverprofile=cover.out ./...

Example: run a script instead of go test

gotestsum --raw-command -- ./scripts/run_tests.sh

Note: when using --raw-command you must ensure that the stdout produced by the script only contains the test2json output. Any stderr produced by the script will be considered an error (this behaviour is necessary because package build errors are only reported by writting to stderr, not the test2json stdout). Any stderr produced by tests is not considered an error (it will be in the test2json stdout).

Example: using TEST_DIRECTORY

TEST_DIRECTORY=./io/http gotestsum

Run tests when a file is modified

filewatcher will automatically set the TEST_DIRECTORY environment variable which makes it easy to integrate gotestsum.

Example: run tests for a package when any file in that package is saved

filewatcher gotestsum

This package is heavily influenced by the pytest test runner for python.
