tparse

A command line tool for analyzing and summarizing go test output.

[!TIP]

Don't forget to run go test with the -json flag.

Pass	Fail

By default, tparse will always return test failures and panics, if any, followed by a package-level summary table.

To get additional info on passed tests run tparse with -pass flag. Tests are grouped by package and sorted by elapsed time in descending order (longest to shortest).

But why?! for more info.

Installation

go install github.com/mfridman/tparse@latest

Or download the latest pre-built binary here.

Usage

Once tparse is installed there are 2 ways to use it:

1. Run go test as normal, but add -json flag and pipe output to tparse.

set -o pipefail && go test fmt -json | tparse -all

2. Save the output of go test with -json flag into a file and call tparse with -file option.

go test fmt -json > fmt.out
tparse -all -file=fmt.out

Tip: run tparse -h to get usage and options.

But why?!

go test is awesome, but verbose. Sometimes you just want readily available failures, grouped by package, printed with a dash of color.

tparse attempts to do just that; return failed tests and panics, if any, followed by a single package-level summary. No more searching for the literal string: "--- FAIL".

But, let's take it a bit further. With -all (-pass and -skip combined) you can get additional info, such as skipped tests and elapsed time of each passed test.

tparse comes with a -follow flag to print raw output. Yep, go test pipes JSON, it's parsed and the output is printed back out as if you ran go test without -json flag. Eliminating the need for tee /dev/tty between pipes.

The default print order is:

• go test output (if adding -follow flag)
• passed/skipped table (if adding -all, -skip or -pass flag)
• failed tests and panics
• summary

For narrow displays the -smallscreen flag may be useful, dividing a long test name and making it vertical heavy:

TestSubtests/an_awesome_but_long/subtest_for_the/win

TestSubtests
 /an_awesome_but_long
 /subtest_for_the
 /win

tparse aims to be a simple alternative to one-liner bash functions.
