json2test

Reverts the result of go tool test2json.

Reason

Imagine you want an Automated Go Tests report in two different formats.

• To produce HTML you can use go-test-report
• To obtain junit.xml you may use go-junit-report

But!

The first one wants json from go test -json in its input, while the second one wants a clean output from go test command.

Steps towards solution

Very naive attempt

Run tests twice.

1. go test -v -json | go-test-report
2. go test -v | go-junit-report

A little dissatisfaction leads to thinking.

The above solution is far far away from a touch of elegance. Almost like Lord Farquaad.

When we look at this pseudo json we notice that it contains the full output of the stdout of the command go test.

Notice the lines that have "Action": "output" `!

So maybe I could get it out? This idea leads us to the next step.

Less naive attempt

Run tests once and use it's pseudo json output as single source of truth

go test -v -json > ssot
cat ssot | go-test-report -o report.html
cat ssot | json2test | go-junit-report > junit.xml

Conclusion

It is obvious that the approach taken is patching.

Two directions to check.

1. Make go-junit-report ingest pseudo json from the command go test -json.
2. Get interested in gopogh

Last word.

However, if my tool is useful to you in any way, use it and if you can let me know that it was useful to someone more than just me.
