go test ./... -json | tparse [options...]
go test [packages...] -json | tparse [options...]

Options:
-h Show help.
-v Show version.
-all Display table event for pass and skip. (Failed items always displayed)
-pass Display table for passed tests.
-skip Display table for skipped tests.
-notests Display packages containing no test files or empty test files.
-smallscreen Split subtest names vertically to fit on smaller screens.
-slow Number of slowest tests to display. Default is 0, display all.
-sort Sort table output by attribute [name, elapsed, cover]. Default is name.
-nocolor Disable all colors. (NO_COLOR also supported)
-format The output format for tables [basic, plain, markdown]. Default is basic.
-file Read test output from a file.
-follow Follow raw output from go test to stdout.
-follow-output Write raw output from go test to a file (takes precedence over -follow).
-progress Print a single summary line for each package. Useful for long running test suites.
-compare Compare against a previous test output file. (experimental)
-trimpath Remove path prefix from package names in output, simplifying their display.
